And that definitely includes the next generation! So we have written two new articles for children. One is about the danger of plastic pollution for animals in the ocean and the other one is about marine invasive species and the rafting of these species on plastic debris. You can find these articles here (in Norwegian): About invasive species: [https://www.nysgjerrigper.no/tema/miljo-og-klima/plast-frakter-dyr/](https://www.nysgjerrigper.no/tema/miljo-og-klima/plast-frakter-dyr/?ref=blog.indecol.no) About plastic pollution: [https://www.nysgjerrigper.no/nn/finn-eit-tema/miljo-klima/plast-farleg-dyra-havet/](https://www.nysgjerrigper.no/nn/finn-eit-tema/miljo-klima/plast-farleg-dyra-havet/?ref=blog.indecol.no) ### Defense of second ATLANTIS PhD student URL: https://blog.indecol.no/defense-of-second-atlantis-phd-student/ Last updated: 2026-07-29T18:07:49.000Z On 31 October 2025 Philip Gjedde succesfully defended his PhD about including marine invasive species impacts into life cycle impact assessment. The defense also included a trial lecture with the title "Inclusion of biodiversity impacts from marine invasive species in maritime polices: Examples, uncertainties and potential economic trade-offs". The very well delivered trial lecture was folllowed with the defense and the opponents Rosalie van Zelm and Marlia Hanafiah asked many critical questions, that Philip answered very well.

Catherine, PhD candidate in ATLANTIS, had the pleasure of attending OOSC in Nice last June🌊. It was a full four days of intensive and essential ocean science aimed at protecting the ocean of tomorrow 🌍. Alongside 619 other scientists presenting their posters at the conference, one thing became clear: the research is available, now we need solutions 🧪. From the perspective of ocean rights and working towards an ecologically sustainable transition, we should focus on what the ocean needs to thrive, rather than what we need from it 🪸. Alarming discussions about pollution and the emergence of novel entities that transgress planetary boundaries, such as plastics, underscore the necessity of this shift 🚫. She had a poster session on: *Is It Fate? Quantifying plastic pollution from land to sea*. Aiming to link existing or in preparation marine impacts to mismanaged plastic waste, so we can quantify the probability of a piece of plastic reaching the ocean globally. ![](https://blog.indecol.no/content/images/2025/10/IMG_0441.jpg) Keep your eyes open, our publication for this fate model will come out in the coming months! ### ESA 2025: IndEcol Presents State-of-the-Art Invasive Species Model URL: https://blog.indecol.no/esa-2025-indecol-presents-state-of-the-art-invasive-species-model-2/ Last updated: 2026-07-29T18:07:52.000Z We know of many environmental impacts of ocean plastic, from entanglement with marine life to microplastic pollution of food webs. But did you know that ocean plastic can help contribute to the spread of invasive species as well? Former MSc student Elisha Wilson has been working closely with ATLANTIS PhD candidate Philip Gjedde to develop a model for the impacts of marine invasive species spread through “rafting” on ocean plastic. Elisha presented the results of this model at the Ecological Society of America’s annual conference in Baltimore, Maryland in August. ![](https://blog.indecol.no/content/images/2025/09/Haram-et-al.--2021.png) An illustration of alien species "rafting" on plastic debris. From **Haram et al., 2021*. Very little is known about ocean plastic’s contribution to the spread of invasive species. Floating natural debris items, such as driftwood or pumice, have always served as a means of transportation for marine life. The difference is, these items sink or degrade after a relatively short period of time, whereas plastic debris items may remain floating on the surface for years or even decades. An increasing number of studies show that these rafting communities can survive for very long periods of time in the open ocean, and that repeated introductions of these communities to new ecosystems almost certainly contribute to new, permanent establishments of rafting species there. What we don’t know is how often this occurs, the chances that new establishments will occur, and where the impacts are most likely to happen. This is where our model aims to shed some light!

Each color represents a different raft as it drifts across the ocean surface, while blue polygons indicate marine ecoregions. Species richness, colonization rates, and biodiversity impacts are mapped onto each of these raft "trajectories" in the model. Our work builds on other exciting research projects happening in ATLANTIS, most importantly the ocean plastic fate model developed by Marte et al. (link) and the MarInvaders database developed by Philip and his collaborators (link). The plastic fates, or trajectories of plastic debris items through the ocean, serve as the fundamental unit of the model. For each plastic item, we model how the community develops over time. This includes colonization rates, local die-off rates, and of course, dispersal rates of the “rafting” species in new ecosystems. When we do this for hundreds of possible plastic fates at the same time, we begin to understand how these floating plastic debris items may pick up and drop off alien species in any given coastal ecosystem worldwide. The presentation at ESA 2025 generated a lot of excitement! Invasive species impacts are mostly invisible, especially in the marine realm, so contributing to public awareness around this issue is an important step towards mitigating them.

The outcome of this collaboration is now published in [*Marine Pollution Bulletin*](https://doi.org/10.1016/j.marpolbul.2025.117869?ref=blog.indecol.no), where entanglement in fishing lines was found to be the leading cause of stranding. Stranded turtles, defined as individuals found dead, injured, or exhibiting signs of poor health, provide valuable information on wildlife and their contemporary threats. Over the course of this project, we looked at more than 10,000 stranding records from 1982 to 2024, made available through NOAA’s Pacific Islands Fisheries Science Center who collaborate with local partners such as Hawai‘i Marine Animal Response ([HMAR](https://h-mar.org/?ref=blog.indecol.no)). Historically, fibropapillomatosis (a virus that causes tumors) has been the most common cause of stranding in Hawai‘i. However, we saw a growing number of strandings linked to fishing line, which became the most prevalent cause as of 2016\. In the latest years, extra in-water searches from wildlife response organizations revealed an even higher number of turtles affected by hook-and-line in local waters. An important takeaway from this study is that many turtles survive fishing-related injuries if they receive such timely assistance. This underscores the value of coordinated stranding response and ongoing marine debris removal efforts. We also noted that the increase in entangled turtles is likely the result of a combination of a growing turtle population overlapping with nearshore fishing activities. Measures to avoid gear loss and interactions with turtles are thus warranted. ![](https://blog.indecol.no/content/images/2025/04/map_Fishing-Line.png) Predicted stranding pattern for green turtles (**Chelonia mydas*) with presence of fishing line found across the Main Hawaiian Islands 2003–2018. To enhance our understanding of the different stranding causes, we developed spatial models which highlighted areas where stranding due to each cause is more likely. For hook-and-line related stranding, the island of Oʻahu, with its high population density and accessible coastline, was identified as a hotspot. The turtles are often entangled in monofilament line, commonly used in recreational fishing. These are difficult to see underwater, accumulate on coral reefs and in nearshore habitats where turtles forage. Interestingly, we found that derelict fishing line was positively associated with coastal access points and proximity to boat harbors, but negatively associated with human population density. Mapping monofilament lines around Oʻahu was possible due to divers from HMAR that conduct clean-ups and record their findings. As such, these missions provide both direct efforts for the environment and a data foundation for research.

How would the future look like if all people and policy-makers would take action against the looming climate and biodiversity crises today? The exhibition centers around the idea of different people having travelled to the future, to 2035, and come back to tell how life in Norway looks like in the future. One of these “time travellers” was Francesca Verones, who painted a scenario for how life in Norway could look like with less plastic waste. The exhibition is open until Autumn 2025. ![](https://blog.indecol.no/content/images/2025/02/IMG_1871.JPEG) ### Disowning a Successful Policy to Pursue Retrograde Actions? URL: https://blog.indecol.no/conservativereversal/ Last updated: 2026-07-06T23:54:52.000Z With support from both member government and EU parliamentarians, the European Commission under the leadership of its conservative president, Ursula von der Leyen, formulated world’s hereto most impactful plan for sustainable development, the [European Green Deal](https://en.wikipedia.org/wiki/European%5FGreen%5FDeal?ref=blog.indecol.no). In its [election manifesto](https://www.csu.de/common/download/Regierungsprogramm.pdf?ref=blog.indecol.no) for the German Bundestag 2021, the CDU/CSU promised to turn German into a net-zero emissions industrialized country by 2045\. The manifesto contains many of the policies, from emission pricing for buildings and transport to carbon border adjustments, that have since become reality. Recognizing the desire of the German automotive industry to move away from combustion engines, the [manifesto](https://www.csu.de/common/download/Regierungsprogramm.pdf?ref=blog.indecol.no) called a build-out of the electric vehicle charging infrastructure and a faster expansion of the electricity grid. That Europe had started a transition away from fossil fuels helped it tremendously to soften the blow from Russia’s aggression 2022, as [I have argued elsewhere](https://iopscience.iop.org/article/10.1088/1748-9326/acdb87?ref=blog.indecol.no). The mistakes of past policies, which created an ill-considered dependency on Russian gas, however, could not be corrected overnight and required painful adjustments by industry and households. European belated [climate policies have been a success](https://blog.indecol.no/climate-policy-progress-and-unfinished-business-under-the-european-green-deal/) by any measure. Many of the detailed laws, regulations, and support programmes came in place, just as they had been promised in the election manifestos. They created a momentum as companies, municipalities, and other actors changed their investments and their future outlook. Investments in renewable energy shot up. Electricity prices came down again after adjustments were for the halted supply of Russian gas. Greenhouse gas emissions now that have entered a trajectory that could allow Europe, [if it completes its Green Deal agenda](https://climate-advisory-board.europa.eu/reports-and-publications/towards-eu-climate-neutrality-progress-policy-gaps-and-opportunities?ref=blog.indecol.no), to fulfill the ambitions laid out by the CDU/CSU in their election manifesto of 2021. **A success to celebrate! A reason to brag!** But what do European conservative parties do? They appear to be about to revert course. While the German car industry is plagued by [inventories of unsold EVs](https://www.ft.com/content/806a46a6-443b-4381-a14b-6ccd910672ee?ref=blog.indecol.no), the European Peoples' Party calls for [protecting the petrol engine](https://www.ft.com/content/61a769cc-478e-4935-9c22-10600710afd1?ref=blog.indecol.no). While German households are still dependent on gas from the unreliable Middle East and the US, the CDU [bad-mouth heat pumps](https://www.linkedin.com/posts/christianstoecker%5Fgut-w%C3%A4re-wenn-journalistinnen-und-journalisten-activity-7271890677255266306-FK3x?utm%5Fsource=share&utm%5Fmedium=member%5Fdesktop). Have they not called for energy efficiency in the past? Promised to electrify the economy? To support the car industry its transition to net-zero? Suddenly these are bad ideas!? Now conservatives appear to run from their own courageous decisions. To pretend it was someone else. To attack others for promises they made to voters one election cycle ago. To criticize laws and rules they voted for. Instead of doubling down on innovation, of creating the industries of the future, some conservatives now promise to back the golden past. They seem to think this can be achieved by supporting what has become low-margin industries. Should the state really try to offset the natural competitive advantage of other regions in basic chemicals production by subsidizing energy? *It is an economic policy that can never succeed.* The reversal of policy is doing great harm to businesses that followed our political leaders. Reversing course now is costly. It will make all future policy harder to implement, because it signals that businesses and investors cannot trust the political class to follow through on its plans. The European Green Deal was the project of a conservative Commission president and broad coalition across the traditional divides of European politics. Once successfully implemented, it will make Europe a better place to live, and less dependent on energy deliveries from powers that do not share our values, our freedom, our rights. Without the major parties coming together, such a monumental task cannot be achieved. I really hope conservatives will remember their past commitment to and leadership of this cause. Europe will not succeed without it. ### The Ocean's Changing Landscape: Insights from the 2024 State of the Ocean Report URL: https://blog.indecol.no/the-oceans-changing-landscape-insights-from-the-2024-state-of-the-ocean-report/ Last updated: 2026-07-29T18:07:57.000Z Our oceans are undergoing significant changes, with pollution, climate change, and biodiversity loss becoming increasingly urgent environmental issues. The *State of the Ocean Report 2024*, published by UNESCO’s Intergovernmental Oceanographic Commission (IOC), throws light on these challenges and emphasizes the need for immediate action. Many of the findings in this report are highly relevant to our ERC-funded ATLANTIS project, which focuses on understanding how plastic pollution is impacting marine ecosystems and exploring solutions to mitigate these effects. **Adapting Global Trends to Local Contexts** One of the key points highlighted in the *State of the Ocean Report* is the importance of recognizing both global trends and local variations in oceans. This is precisely what the ATLANTIS project aims to achieve. Rather than adopting a generalized approach, we focus on regional perspective to better understand how local environmental factors influence the impact of plastic pollution on marine ecosystems. By adopting a regionalized approach, we can more effectively assess the impacts of plastics and develop clearer, more targeted strategies to protect marine environments. **Tracking Plastic Pollution: Understanding its Fate** Marine pollution\`s fate has been poorly studies, particularly plastic and nutrient. Without comprehensive tracking, it is difficult to develop effective strategies to mitigate their impact on marine life. At ATLANTIS, several PhDs are working to understand the fate of plastic in the ocean\[1,2\]. Using Lagrangian particle models\[3,4\], we are studying how plastics move across ocean currents, accumulate in certain areas, and pose risks to marine life. This fate is crucial for developing more accurate impact models and targeted interventions. **Blue Carbon: The Intersection of Climate Change and marine plastics** Marine ecosystems play critical role in combating climate change. By capture and store carbon through biological and physical pump, oceans help mitigate the effects of global warming. In ATLANTIS, our research investigates how plastic pollution can interfere with the growth of algae, a key primary producer. Algae is vital in carbon sequestration because of photosynthesis, but plastics can inhibit their growth, reducing the ocean's blue carbon capacity. This research is an important part of our work, and more details on this topic will be shared soon, as our paper is currently under review. **Conclusion** The *State of the Ocean Report 2024* highlights the growing challenges facing our oceans, but it also calls for action and the development of solutions that address both global and local scales. The ATLANTIS project is committed to contributing to these efforts by investigating the fate of plastic pollution and its impacts on marine ecosystems at a regional level. As we continue our research, we remain focused on developing strategies to protect the ocean and ensure its resilience in the face of increasing environmental threats. \[1\] Høiberg, M.

New PhD in ATLANTIS URL: https://blog.indecol.no/whos-that-girl-new-phd-in-atlantis/ Last updated: 2026-07-06T23:55:08.000Z After working as a research assistant in ATLANTIS, I, [Catherine Deschênes,](https//www.linkedin.com/in/catherine-deschenes-452732160) am happy to announce that I have started a PhD in that same project. With ATLANTIS being extended a year until March 2026, an opportunity came up for me to step-up as a PhD in ATLANTIS. With a background in environmental chemistry and marine biology, and a master thesis on microplastics sampling and characterisation, I am excited to start a PhD in quantifying the fate and assessing the aquatic impacts of plastic pollution for Life Cycle Impact Assessment (LCIA). What does it entail if we mismanage 1 kg of plastics on land for biodiversity in the ocean? What will the probability be that this kilo reaches the ocean and in turn affects marine organisms through ingestion or entanglement? This PhD will help link other research done within the ATLANTIS project and will therefore connect the studies together. Otherwise, if I am not trying to follow plastic around, I am probably out-and-about in the wonderful Norwegian nature. ### ATLANTIS Members Lead Two Events on Plastic Pollution URL: https://blog.indecol.no/atlantis-members-lead-two-events-on-plastic-pollution/ Last updated: 2026-07-29T18:08:00.000Z Earlier this month, members of the ATLANTIS project took part in two events related to plastic pollution. These events brought together researchers, PhD candidates, and the public to explore the impact of plastics on the environment and highlight the need for urgent interventions. --- **The MAPLE Project in the Spotlight** On the 1st of October, the MAPLE project, led by Francesca Verones, took center stage in an engaging popular science dissemination event at [Young Researchers at Dokkhuset, Trondheim](https://www.ntnu.no/kveld/marine-plastic-pollution?ref=blog.indecol.no). Francesca, along with the four PhD candidates – Jenny, Gabrielle, Jakob, and Ahmed – presented their research in a style that made complex scientific ideas accessible to a broader audience. Each PhD project was shared through a popular science lens, sparking lively conversations about the global plastic crisis. ![](https://blog.indecol.no/content/images/2024/10/IMG_6806-2.jpg) Final Q&A session with the audience. Photo credit: Stig Andre Larssæther The event wasn't just confined to the room; [it was livestreamed online](https://www.youtube.com/watch?v=kSKahwRUoeE&ref=blog.indecol.no), allowing a wider audience to tune in and participate. The event ended with a Q&A session, focusing on the pressing concerns of plastic pollution and how it affects our environment. The audience, both online and in-person, left with a greater understanding of the issue and the ongoing research to combat it. --- **Workshop on Plastic Research and Innovation** The following day, on the 2nd of October, more than 20 researchers from the ATLANTIS, MAPLE, and SWEETSPOT projects gathered at Gløshaugen for an intensive workshop. This collaborative event aimed to foster the exchange of ideas and explore potential collaborations across various fields related to plastic pollution. La elección de [camisetas de fútbol retro para regalar](https://www.camisetatienda.com/?ref=blog.indecol.no) mejora al comparar la temporada, el diseño y los detalles históricos. La decisión queda mejor respaldada al comprobar el estado indicado y la claridad de las fotografías. Presentations covered a range of topics, including the transport and degradation of plastic, the impacts of plastic on marine ecosystems, plastic flows and circular economy models, and innovations and interventions to tackle the plastic crisis. One of the highlights was a group discussion focused on the future – exploring new research avenues, sharing methodologies, and identifying opportunities for collaboration. The workshop concluded with a dinner, where participants continued to exchange ideas in a more informal setting, laying the groundwork for future joint efforts. ### Reducing GHG emissions from global buildings URL: https://blog.indecol.no/reducing-ghg-emissions-from-global-buildings/ Last updated: 2026-07-29T18:08:02.000Z **Demand reduction, circular economy, and substitution offer complementary emission savings** A new scenario analysis for the global building stock confirms quicker and deeper emission reductions from combining biogenic building materials, lightweighting, lifetime extension, reuse/recycling, and demand reduction; compared to employing each strategy individually. [In a new paper in the Journal of Industrial Ecology](https://doi.org/10.1111/jiec.13557?ref=blog.indecol.no), [Stefan Pauliuk](https://www.blog.industrialecology.uni-freiburg.de/?ref=blog.indecol.no), [Fabio Carrer](https://www.linkedin.com/in/fabio-carrer-b870141b7/?ref=blog.indecol.no), [Niko Heeren](https://nheeren.github.io/?ref=blog.indecol.no), and I extended our previous modelling to include non-residential buildings and updated the analysis. Important insights: \- In all scenarios, material inflows are much larger than outflows. It is because of a growing population and the urbanization of Sub-Saharan Africa and South Asia. This new demand limits the scope of circular strategies such as lifetime extension, reuse, and recycling, as they do not apply in regions where demand for new building space is largest. These strategies are most effective in developed countries with an aging building stock, such as Europe. \- The largest material savings are achieved by reducing demand growth, limiting the amount of building space that each of us uses both for residential and non-residential purposes. Tax rules and planning drive demand for excessive building space beyond what it would be otherwise. They should be reversed. \- Non-residential buildings are of comparable importance to residential buildings. However, so far, they have received much less attention. We have previously only investigated office buildings, an important segment. \- The substitution of biogenic building materials for cement and steel offers significant opportunities for emission reductions that are larger than from circular strategies such as light-weighting, lifetime extension, and improved reuse/recycling. However, supply of such building materials is limited. We have primarily focused on wood but think that other materials such as bamboo, straw, reeds could offer additional supply. ![](https://blog.indecol.no/content/images/2024/10/Building_Material_Demand.jpg) Future material demand for all buildings according to scenario. Benefit of lower demand compared to implementation of all other circular economy (fullCE) measures. Together, these strategies can reduce cumulative emissions between 2020-2050 by as much as 44%. This reduction is substantial given the large in-built inertia. The strategies are also complementary to emission reductions from decarbonizing the energy supply and would allow for a quicker and steeper decline in emissions.

For electioneering politicians, climate action appears to be limited to crisis management. Pausing emission reductions, as they suggested before the floods, will bring new, more severe crises in the future.* Most of Austria's parties seem to think they have done enough, or maybe even too much, to reduce greenhouse gas emissions, for now. At least that's what I deduce from the questions posed by TV journalists and the comments in newspapers. It worries me because it is based on a fundamental miscalculation of the situation. A big concern has been a rhetoric about the cost of emission reductions. All the while, they oversee that in recent years, our dependency on fossil fuels has cost us more dearly than the current phase-out. One can see, however, that many comment-field comments suggest high energy prices are the result of climate action, rather than the consequent of a combination of earlier climate inaction and Russia's strategy of pressing Europe to not interfere with its recolonization of the Ukraine. As one of 15 climate researchers in the [EUs Climate Advisory Board](https://climate-advisory-board.europa.eu/about?ref=blog.indecol.no), I contributed to a report on the [2022-23 energy price crisis](https://climate-advisory-board.europa.eu/reports-and-publications/addressing-the-energy-crisis-while-delivering-on-eus-climate-objectives-recommendations-to-policy-makers?ref=blog.indecol.no) and two [subsequent](https://www.nature.com/articles/d41586-023-00766-y?ref=blog.indecol.no) [comments](https://iopscience.iop.org/article/10.1088/1748-9326/acdb87?ref=blog.indecol.no). Our analysis is also shared by other experts: The trigger of the crisis was clearly Central Europe's dependence on Russian gas, which Russia instrumentalized in the war against Ukraine. Russia had already cut gas supplies before the attack on Kyiv and emptied gas storage facilities in Central Europe unnoticed. **Russia intended gas shortage** The energy transition that has been initiated has made it easier for Europe to respond to the reduced gas supply. On the one hand, renewable energy supply had already begun, and on the other hand, Germany was able to reactivate old coal-fired power plants that had just been taken out of operation at short notice. In addition, there were already plans, expertise, and capacity to save energy. Thanks to these circumstances, the crisis was overcome relatively quickly, but not painlessly. In retrospect, one can only state that natural gas was an expensive source of energy. In its report, the expert council recommended doubling the investment rate in renewable energies, saving energy, and replacing fossil gas and oil with electricity. We advised against energy subsidies. Instead, we recommended cushioning social impacts through targeted donations. Posters of populist right and left parties (FPÖ, KPÖ) before the European elections blamed the EU for the high prices. They indicated that inflation would be brought back under control by currying favor with Russia. These parties seem to want to return to the dependence of 2022 that triggered the energy crisis in the first place. **Energy transition strengthens Europe** Only increasing domestic energy production and avoiding energy waste can reduce Europe's dependence on fossil fuel imports. Unfortunately, the expert council against subsidizing fossil energy was ignored. Investments in solar systems, heat pumps, EVs and home insulation have fallen far below the capacity of the economy today. In this way, we are prolonging our dependence on imported fossil energy and keeping our CO2 emissions higher than necessary. [A review of European climate policy by the Council of Experts](https://climate-advisory-board.europa.eu/reports-and-publications/towards-eu-climate-neutrality-progress-policy-gaps-and-opportunities?ref=blog.indecol.no) shows that great progress was made in the last EU legislative period, which contributed to the reduction of CO2 emissions. At the same time, there are many planned measures that have been prepared but not yet decided, and decisions that have yet to be implemented by the member states. One example of this is the energy-efficient renovation of buildings. Reducing climate change is important to protect ourselves from climate damage, even if it is not sufficient given all the emissions we have already caused. Austria has not been a pioneer in climate policy; rather it lacks behind in the formal policy making process, despite progress in actual measures in recent years. Journalists no longer ask about the topic, and politicians hardly mention it. Instead, the population should be prepared for imminent, difficult decisions. I am worried that the new Austrian government could become a brake for EU climate protection. This would be irresponsible. ### Defense of first ATLANTIS PhD URL: https://blog.indecol.no/defense-of-first-atlantis-phd/ Last updated: 2026-07-29T18:08:05.000Z On Friday the 13th of September Marthe Alnes Høiberg defended her PhD thesis with the title “Towards inclusion of plastic pollution in Life Cycle Assessments: Impacts of entanglement from species to ecosystem quality level”. Marthe has written about the impacts of plastic entaglement within life cycle impact assessment and has conducted a study for Hawaiian turtles in more details. Marthes defense started with a trial lecture on the topic “Assessing damage on marine ecosystem quality in LCA: recent developments and future needs”. Marthe did a great job to present the ongoing developments in our field in a pedagogic way and has presented excellent reflections for future developments. The defense itself was a very good presentation followed with an excellent exchange of questions and answers with the two opponents Arnaud Hélias and Elena Corella-Puertas. Marthe did an excellent job and we are all very proud of her!

While many studies have addressed and reported on different impacts of plastic pollution, the Life Cycle Assessment (LCA) community are still working on incorporating this information into the framework, i.e., by developing relevant inventory and impact assessment methods. Our study represents a piece of the puzzle towards filling the methodological gap of plastic pollution impacts. In this paper, we introduce the first spatially explicit Characterization Factors (CFs) for quantifying impacts of plastic entanglement on marine megafauna, including mammals, birds, and reptiles. We developed a framework that combines Lagrangian particle tracking and a Species Sensitivity Distribution (SSD) model to estimate the potential entanglement impacts from lost plastic-based fishing gear across the world. We simulated plastic losses from global fishing hotspots (Figure 1) and generated country-specific CFs to be used in LCA combined with estimates on the quantities of gear loss. ![](https://blog.indecol.no/content/images/2024/08/norway_map_hoiberg2024.jpg) Figure 1: Example of spatial distribution following hypothetical releases of plastic in fishing hotspots in Norway. Our research follows a relative global impact assessment approach, where the effects are estimated to be higher in areas where susceptible species overlap (Figure 2). As a consequence, the CFs associated with Oceania were found to be higher than those of Europe, Africa, and Asia, illustrating regional differences in vulnerability. ![](https://blog.indecol.no/content/images/2024/08/efmap.jpg) Figure 2: Effect Factors (PAF/kg) By incorporating entanglement along with other plastic pollution impacts in LCA, we can provide a more complete assessment for policymakers and industries where plastic is involved, thus supporting informed decision-making with marine ecosystem health in mind. Whileour study lays the groundwork for one type of effect of marine macroplastic, future work could expand on this model by incorporating relevant fate processes as well as differentiating impacts based on the type of plastic and specific environmental compartment.

There are many who have quantified the spread of invasive species, and a few who have tried to generally quantify the impact after said spread. Until now. [In our new article](https://doi.org/10.1007/s11367-024-02325-7?ref=blog.indecol.no), we assess a relative impact, globally and regionally. As a result we can map out sort of a "priority map" showing hotspots where we must be extra careful to avoid invasions, see the figure. The goal of this work is the novel implementation of characterizing marine invasion impacts on biodiversity in life cycle impact assessments (LCIAs). That is, eventually we can connect two measures: (i) How many invasions are caused by flows in our industry (e.g., shipping, macro plastic emissions), and (ii) the relative loss of biodiversity once this happens (the effect factors presented in this article). ![](https://blog.indecol.no/content/images/2024/06/EFs_and_violins_bigger_map.png) The impact on biodiversity caused by a successful invasion in the marine, measured in potentially dissapeared fraction (PDF) of native species. The impact is on a log-scale where red is the highest impact. Green regions have no alien species, and blue regions have no species threatened by invasive species specficially. The figure also show the distribution of effect (EF) or "relative threat frequency" specifically for biological invasions (Φ(inv)) in violinplots on the side. The latter distribution indicates how much of the total threat in an area is from invasive species and not some other kind of threat, like pollution, fishing, climate change, etc.. This shows that we should be extra careful in the Atlantic and Southern Ocean as the trend show that these places are impacted the highest. Especially the Southern Ocean, which have almost no data on alien introductions yet, have a high fraction of threat from biological invasions. This trend also signals another message: "Pristine ecosystems are the most prone to invasions". Once these effect factors are multiplied with factors describing the spread of invasive species through different pathways (in LCIA terms: "Fate factors") we can begin assessing hotspots for biodiversity loss from said pathways, comparatively. For example: La elección de [camiseta de la selección](https://www.camisetatienda.com/?ref=blog.indecol.no) mejora al comparar el equipo, la temporada y el tipo de camiseta. Antes de pagar, es útil verificar el tallaje disponible y el plazo de entrega. - Which shipping route cause the most impact to biodiversity by spreading invasive species? - Or, where on the shipping route should we focus our resources to minimize the impact? - Or, are any locations worse than others in relation to where littered plastic is released to the ocean, and so also where it ends up? Biological invasions is often dated back to a "mainstream" introduction by [Charles S. Elton in 1958](https://doi.org/10.1007/978-1-4899-7214-9%5F1?ref=blog.indecol.no), but the scientific interest of the topic is much older. Introducing biological invasions to the life cycle assessment (LCA) framework, however, is no older than the novel attempt by [Hanafiah et al. in 2013](https://doi.org/10.1021/es403870z?ref=blog.indecol.no) relating the concept to impacts on freshwater ecosystems from inland shipping. Along with the model from [Borgelt et al.2024](https://doi.org/10.1021/acs.est.3c08500?ref=blog.indecol.no) on terrestrial ecosystems, this model is the first step towards implementing biological invasions in LCA. And so, we can soon begin assessing one of the five greatest impacters to biodiversity loss, and how this is connected to the life cycle, or product chains, throughout our industry. ### ATLANTIS visits second graders URL: https://blog.indecol.no/atlantis-visits-second-graders/ Last updated: 2026-07-06T23:56:07.000Z Francesca Verones and Martin Dorber visited a second class in Trondheim to teach and inform about plastic and its environmental impacts. We talked about how plastics are made, how much is thrown away and what happens with the plastic that is not properly managed. The children were very engaged and quick to find all the things that are made from plastic in their classroom, which turned out to be many and diverse things from laminated paper, to bags and T-shirts, boxes and pens, to water bottles and chairs. We had collected a box of plastic waste from the coastal area in Mausund, an island outside the Trondheimsfjorden, where a lot of plastic is found. The kids enjoyed digging through the waste and were astonished to find the diversity of plastic items they could find, from fishing lines, to bottle caps, pacifiers, plastic bags and toys. It was impressive to see how much the children already knew about how plastic is affecting marine wildlife. We talked about entanglement and ingestion, and we shared experiences and pictures from the stay in Hawaii. The children also had very good ideas for how to reduce the plastic problem! All in all, this was a visit that made us hopeful for the future. Despite the large issue with plastic today, the youngest generation seems to be very aware of the problems and is aware of solutions to mitigate the issue. They are interested and curious to learn more about the impacts and solutions. If we can in the coming years put all the solutions to actual practice, this will definitely help to solve the global plastic problem once and for all! ![](https://blog.indecol.no/content/images/2024/05/Copy.jpg) ![](https://blog.indecol.no/content/images/2024/05/Image--4-.jpg) ![](https://blog.indecol.no/content/images/2024/05/Image.jpg) ![](https://blog.indecol.no/content/images/2024/05/Schoolvisit.jpg) Impressions from the school visit.

Historically, around 90% of global fossil hydrocarbons have been used as fuels for electricity generation, industry, transport, and heating. The remaining 10% serves mainly as raw materials (feedstocks) for the chemical industry, leading to the production of plastics, fertilizers, and a range of chemicals crucial to various industrial processes. However, as climate action requires a paradigm shift in fossil hydrocarbon usage, countries have reached a consensus to decarbonize their energy sectors by transitioning away from fossil fuels. Many oil giants are pivoting from energy provision to material manufacturing, with most new chemical complexes leveraging oil-to-chemical (OTC) technology that can transform up to 70%-80% of crude oil into high-value chemicals. Despite these shifts, the metabolic patterns of fossil resources, especially in the complex chemical industry, have not been thoroughly explored. This knowledge gap stems from the inherent diversity and complexity of chemical products and production processes. ![](https://blog.indecol.no/content/images/2024/05/Figure_1.png) *Figure 2\. Schematic diagram of fossil hydrocarbon usage and an overview of this study* **Complexities of China’s Chemical Industry** China plays a critically important role in the global chemical sector due to its world's largest production volume, comprehensive process network, and high fossil hydrocarbon consumption. Generally, crude oil and natural gas constitute the primary fossil feedstocks in the chemical industry. In China, most downstream chemical products are derived from crude oil through petrochemical processes. Approximately 70% of the oil and 37% of the gas required to meet demand are imported due to limited domestic oil and natural gas resources. Hence, coal is also used as an important feedstock, specifically utilized, for example, for producing methanol and generating hydrogen for ammonia synthesis. As such, most chemical products manufactured in China are still oil-based. To better understand the complexity of China’s massive chemical production systems, researchers from Tsinghua University, NTNU Indecol, and other collaborators developed a tailored process-based material flow model for China. The model highlights the interconnected mass and carbon flows within the expansive gate-to-gate production network, encompassing seven primary chemicals, 48 intermediates and final products, and 71 major production processes. This analysis revealed the material flows of coal, oil, and natural gas across the production chain, providing estimates of direct and indirect CO2emissions. In 2017, China’s chemical industry used 90 million tons of crude oil, 13 million tons of natural gas, and 180 million tons of coal, as feedstock, constituting 15%, 7%, and 5% of China’s respective total consumption. Process emissions from primary chemicals in 2017 amounted to 300 million tons of CO2, while energy-related emissions (from primary chemicals) were slightly higher at 340 million tons. As China seeks to reduce CO2 emissions without increasing oil and gas imports, improving energy efficiency, shifting to renewable and nuclear power, and utilizing green hydrogen will be crucial. The remaining emissions can be tackled with carbon capture, utilization, and storage (CCUS). **Look into the Future and Stakeholders' Engagement** The chemical industry plays a significant role in the structural transition from fossil “energy” to fossil “feedstock”, given the world's climate ambitions. The complex material flow of fossil feedstock to products revealed by this study significantly enhances our understanding of fossil hydrocarbon metabolism. It also provides a solid foundation to connect supply-side and demand-side solutions in future investigations into the industry's decarbonization. The scale of China's chemical industry is expected to continue expanding in the foreseeable future. Consequently, greater efforts will be required for energy conservation and emission reduction. Converting coal to chemicals requires large-scale hydrogen substitution, which is energy-intensive when using water as the hydrogen source. Part of the carbon in the feed is oxidized to absorb the oxygen from the water molecules. Green hydrogen could drastically reduce emissions—by up to 68% compared to traditional processes. Given that much of China's chemical production is situated in coal-rich regions with significant renewable energy potential, integrating green technologies makes sense. This approach leverages existing infrastructure and shifts facilities towards more sustainable practices without starting from scratch. However, scaling up these new technologies to meet the 2030 timeline will present significant challenges, requiring a blend of innovation, investment, and commitment. Continuous collaboration with industry experts is essential to refine strategies that enhance energy efficiency, integrate sustainable practices, and promote a circular economy. Dialogue with practitioners on decarbonizing the chemical sector revealed a difference in outlook compared to environmental experts. This disparity may stem from varying perspectives on the industry, differing interpretations of economic and technological factors, and the overall complexity of sustainability considerations. This contrast underscores the need to challenge current norms and incentivize pragmatic decarbonization. Regular reviews and models that account for regional differences in production methods are crucial as the industry expands. Moreover, shifting consumer behavior to reduce plastic waste and support circular flows will be vital for achieving effective decarbonization. The research, led by researchers from Tsinghua University and NTNU Indecol, was recently published in ***Nature Communications***.

This newly initiated project in the archipelago seeks to leverage artificial intelligence (AI) to monitor and combat the plastic pollution washing up on its shores. **Frøya's Archipelago: A Natural Filter of Floating Debris** Plastic pollution has escalated into one of the most pressing environmental issues of our time. Every year, millions of tons of mismanaged plastic waste enter our oceans, carried by rivers, winds, and tides. This has profound implications for regions like Frøya's Archipelago, where the currents deposit significant amounts of plastic on the shores. ![](https://blog.indecol.no/content/images/2024/04/output_resized_loop.gif) Frøya's Archipelago, with its strategic location in the path of the Gulf Stream's currents, acts as a natural filter, intercepting floating debris. The shores now bear witness to the relentless accumulation of plastic waste. The consequences of this pollution are manifold. Marine life suffers greatly; seabirds, fish, and mammals mistake plastic for food, leading to ingestion and entanglement. The degradation of plastics results in microplastics, tiny particles that can penetrate deep into the marine food web and even into the human food chain. Beyond the ecological impacts, the aesthetic degradation of natural landscapes like Frøya's Archipelago diminishes their recreational, cultural, and economic value. Monitoring this accumulation is not just crucial for understanding the scale of pollution but also for initiating effective cleanup and prevention strategies. **The Role of Artificial Intelligence in Environmental Monitoring** In response to this pressing issue, a pioneering project is being launched in the archipelago, where multiple cameras are being installed at strategic locations to capture the influx of plastic debris. These images serve as the eyes of an AI-driven monitoring system designed to detect plastic litter. By analyzing images taken at hourly intervals along the shoreline, AI algorithms can track the accumulation of plastic debris over time. This information is invaluable for scientists, conservationists, and policymakers working to address the issue of plastic pollution. ![Imagen que contiene exterior, foto, pequeño, cubierto Descripción generada automáticamente](https://blog.indecol.no/content/images/2024/04/Picture1.png) AI and machine learning algorithms are at the heart of this project, offering a way to sift through vast amounts of visual data quickly and accurately. By training these algorithms to recognize plastic debris, the project aims to automate the detection process, providing real-time insights into how, where, and when plastic accumulates. #### Benefits of AI in the Fight Against Plastic Pollution - **Efficiency**: AI can analyze large datasets far quicker than humanly possible, making it feasible to monitor extensive coastal areas continuously. - **Accuracy**: With the ability to learn from thousands of images, AI models reduce the likelihood of human error, ensuring precise detection and classification of plastics. - **Data-Driven Insights**: The project will generate a wealth of data on pollution patterns, informing more effective cleanup operations and preventive measures. This project is in its early stages, with cameras currently being installed across the archipelago. These cameras will feed images into the AI system, which will analyze the data to map the distribution and accumulation of plastic waste. Over time, the system accumulates a wealth of data, revealing trends in pollution accumulation. This information is crucial for both for developing biodiversity impact models and for targeted interventions, [from cleanup efforts](https://eider.no/?ref=blog.indecol.no) to policies aimed at reducing plastic usage. This technological approach not only enhances our understanding of plastic pollution dynamics but also aids in the development of targeted cleanup operations. By pinpointing hotspots and timing of litter accumulation, cleanup efforts can be directed more effectively. **Looking Ahead** The integration of AI into environmental conservation efforts in Frøya's Archipelago represents a fusion of technology and nature, offering a glimpse into the future of environmental protection. As AI technology advances and becomes more accessible, its potential for addressing global challenges like plastic pollution continues to grow. However, technology alone cannot solve the problem. Reducing plastic pollution requires a multifaceted approach, including policy changes, public education, and improvements in waste management practices. AI provides us with the tools to understand and combat pollution more effectively, but collective action is essential to create a sustainable future for places as vulnerable as Frøya's Archipelago. ### Ocean Sciences Meeting 2024 URL: https://blog.indecol.no/atlantis-and-the/ Last updated: 2026-07-06T23:56:30.000Z Every two years, the [Ocean Sciences Meeting,](https://www.agu.org/ocean-sciences-meeting?ref=blog.indecol.no) co-sponsored by the American Geophysical Union, the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS), brings together the ocean community to exchange findings, foster connections among scientists worldwide, and advance the impact of science. ![](https://blog.indecol.no/content/images/2024/03/conference.jpg) The Ocean Sciences Meeting 2024 (#OSM24) took place in New Orleans, Louisiana, from February 18th to 23rd, 2024, where I had the opportunity to represent the [ATLANTIS project](https://atlantis-erc.eu/?ref=blog.indecol.no) among nearly 6000 attendees. I successfully proposed and moderated a session titled” “Toward a Sustainable Ocean: Holistic Tools, Transdisciplinary Approaches, and the Next Generation of Ocean Solutionists”, together with [Stephanie Sharuga (Bureau of Ocean Energy Management)](https://www.boem.gov/about-boem?ref=blog.indecol.no) and [Carlie Wiener (Schmidt Ocean Institute)](https://schmidtocean.org/person/carlie-wiener/?ref=blog.indecol.no). Initially I had a poster in this session titled “Sustainable consumption and production: “Integrating "Whales, Waste and Sea Walnuts” into Life Cycle Assessment”, but due to some last-minute dropouts, I was additionally permitted to present it in the oral session. ![](https://blog.indecol.no/content/images/2024/03/poster.jpg) Furthermore, [Francesca Verones ](https://www.ntnu.edu/employees/francesca.verones?ref=blog.indecol.no)had an oral presentation for her abstract titled "The Perception of Ecosystem Services and Threats Globally: How Different Are We?" I stepped in on her behalf and used the opportunity to share the latest ATLANTIS results with the community. In summary, the ATLANTIS project gained significant visibility and attention, leading to new collaboration opportunities and challenging questions on how to connect the results to a broader audience. ![](https://blog.indecol.no/content/images/2024/03/presen.jpg) Now, let's dive deeper into what I am taking away from the conference for both myself and the ATLANTIS project. The conference started with a planetary session, highlighting environmental injustice at the Mississippi River, also known under the nickname “cancer alley”. Although slavery in the agricultural field has ceased, it has been replaced by chemical factories polluting its surroundings. This was impressively reinforced by stories from the residents. It served as a good reminder that every quantifiable number of our models is grounded in real consequences and that environmental decision-making needs to consider various factors at the same time, such as biodiversity and social consequences. ![](https://blog.indecol.no/content/images/2024/03/missi.jpg) Another key takeaway was the omnipresence of AI and cloud computing. NASA presented its [podaac database ](https://podaac.jpl.nasa.gov/?ref=blog.indecol.no)for sharing remote sensing data and discussed new satellite missions on the horizon. With the abundance of available data, cloud computing becomes essential for processing, leaving only the final results as output on local computers. Integrating this data with citizen science and AI will greatly increase data and knowledge availability, particularly regarding species presence data. Examples include detecting species in videos from autonomous vehicles, conducting wildlife surveys from planes using AI algorithms in tandem to provide results before landing, and automatically identifying all species in seabed images. This all provides new input data for more sophisticated impact models. Concurrently, Environmental DNA is rapidly advancing in the marine sector. Could all these developments soon enable us to model impacts on a monthly scale? Moreover, many presentations reminded me that impacts can vary significantly depending on the life stage of a species. For instance, during the construction of offshore wind farms, juvenile fish appear to be more sensitive to noise impacts than adults. Additionally, studies have shown that ingestion impacts for turtles vary by species. While one turtle species predominantly ingests white plastic, despite not preying on jellyfish, another species primarily ingests red plastic. Additionally, numerous presentations focused on plastic research. One significant question still remains: How exactly does plastic flow through the ocean after being improperly managed? It's reassuring to see that the ATLANTIS project, particularly the work of [Marthe Alnes Høiberg](https://www.ntnu.no/ansatte/marthe.a.hoiberg?ref=blog.indecol.no), is addressing this research question by developing a global Macroplastic fate model. What we understand is that plastic accumulation continues unabated, both in the ocean plastic gyres and in coastal regions. What's alarming is the rapid pace at which this is occurring. Several presentations highlighted that these rates are not currently linear but closer to exponential. This underscores the urgency for decision-making regarding plastic and underscores the importance of the models being developed in ATLANTIS. ![](https://blog.indecol.no/content/images/2024/03/platsic.jpg) Mississippi river: 300 meters from the conference venue ### EU's climate target within reach thanks to the European Green Deal URL: https://blog.indecol.no/climate-policy-progress-and-unfinished-business-under-the-european-green-deal/ Last updated: 2026-07-29T18:08:09.000Z Naysayers argue nothing can be done about climate change; action is too costly, disruptive, and technically challenging. Anarchists argue emissions are fault of the economic system; we need to overthrow capitalism and degrow the economy to reduce emissions. Europe may be about to prove both sides wrong. Greenhouse gas emissions of European Union member states were [32.5% lower in 2022 than in 1990](https://climate.ec.europa.eu/system/files/2023-11/com%5F2023%5F653%5Fglossy%5Fen%5F0.pdf?ref=blog.indecol.no). In 2023, the EU managed a substantial emission reduction of [five percentage points](https://globalcarbonbudget.org/carbonbudget2023/?ref=blog.indecol.no), according to projections of the Global Carbon Project, a group of scientists. This substantial emission reduction is the result both of climate policy progress and high energy prices following Russia’s war on the Ukraine. If the EU successfully concludes and implements the European Commission’s climate policy proposals, it may be well on track to achieving its ambitious emissions targets of minus 55% in 2030 and net-zero in 2050. [Unparalleled but incomplete progress](https://climate-advisory-board.europa.eu/news/eu-climate-advisory-board-focus-on-immediate-implementation-and-continued-action-to-achieve-eu-climate-goals?ref=blog.indecol.no) is the main finding of an assessment of European climate policy by the independent [European Climate Advisory Board](https://climate-advisory-board.europa.eu/?ref=blog.indecol.no), which was created under the EU’s climate law of 2022\. The scientists point to large gaps in agriculture, which has not managed to reduce emissions at all. They miss systematic attention to saving energy and materials. They see substantial and unmet investment needs, in installations that will have very low running expenses. They identify opportunities for further emission reductions, some profitable such as the phase-out of fossil-fuel subsidies and other economic distortions in favour of resource overconsumption. *Late turn-around following costly mistakes.* Like the rest of the world, Europe is late in realizing the depth of change in development needed to build a zero-carbon economy and staking out a course of reaching that goal. Past mistakes, such as making oneself dependent on cheap Russian gas and investing heavily in diesel engines rather than car battery technology, imply costly course correction now. Before 2019, the EU had put in place a general climate policy architecture, including an Emissions Trading System which puts a price on emissions from large stationary polluters, national emission targets for buildings, transport and agriculture, and technology standards. The carbon price was low, and progress was piecemeal and always counteracted by policies in agriculture, transport, and industry that increased emissions. *Finally, real leadership* With the European Green Deal from 2020, the Commission under the impressive leadership of Ursula von der Leyen and supported by the European Parliament and Council, has undertaken comprehensive policy reform addressing many emission sources. Not all policy proposals have yet been approved, however, and many still need to be implemented by the member states. Implementation can be more or less ambitious, more or less effective, slow or fast. The Board finds that only a swift and effective implementation of the proposed policies will allow the EU to meet its emission target for 2030\. A successful completion of the European Green Deal, which is well under way, would demonstrate European leadership in addressing one of the fundamental challenges of our times and put pressure on other governments. ![](https://blog.indecol.no/content/images/2024/01/VonDerLeyen.webp) The European Commission is currently the most important force for emission reductions. Here Commission president Ursula von der Leyen. Picture: Etienne Ansotte, © EU *Opportunities to save tax money and the planet.* What struck me most in reviewing European climate policy is the persistence of policies that are both costly and cause of emissions. The European Court of Auditors has repeatedly criticised [fossil fuel subsidies, which have not been reduced](https://www.eca.europa.eu/en/publications?did=60760&ref=blog.indecol.no) over the past decades. Further, tax breaks support excessive energy use, unsustainable agricultural practices, and large residences. Why do our politicians feel that this is a good use of our tax money? These are past mistakes that need to be urgently corrected, but they imply confronting special interest groups who benefit from public largess. Sometimes fossil fuel subsidies and energy tax breaks also benefit less well-off parts of the population. In these cases, the board recommends, targeted policies should be put in place to help people and businesses to adjust. *Despair or indifference? There is a better alternative.* The transition to net-zero will need to continue after 2030\. Policy implementation is not at all trivial, from renovating an aging housing stock to constructing the required electricity grid. But the fact that the crucial milestone of a 55% reduction is well in sight demonstrates the feasibility of moving away from fossil fuels. With redoubling our efforts, rather than overthrowing the system or throwing up our hands in despair, we can solve one of the big challenges of our times! Denying progress, as both activists and populists are prone to do, falsely suggests that we are on the wrong way when we have finally begun to turn the ship around.

These bans have typically targeted packaging and other single-use items as this equates to about half of all plastics produced, and most consumer items used one single time surely do not need to be as persistent as plastic is. Now in 2024, UN member states are also set to commit to a legally binding global resolution with a life cycle perspective to end plastic pollution ([1](https://www.unep.org/news-and-stories/press-release/historic-day-campaign-beat-plastic-pollution-nations-commit-develop?ref=blog.indecol.no)). This aligns well with ATLANTIS’ research goals, which is to develop global models for marine impacts of plastics in life cycle assessments, allowing impacts from “cradle to crave” to be considered when comparing different products or production options. While details of the global agreement are in sight but yet to be finalized, several NGOs such as the Marine Conservation Society and the Ocean Conservancy have urged for the treaty to target plastic waste in the form of Abandoned, Lost or otherwise Discarded Fishing Gear (ALDFG). Fishing nets, lines and ropes are typically made from non-degradable polymers such as polyethylene (PE), polypropylene (PP) and nylon, and constitute a direct and significant source of plastic to the marine environment. To quote Nicholas Mallos from the Ocean Conservancy: > [2](https://oceanconservancy.org/news/global-plastics-treaty-ghost-gear/?ref=blog.indecol.no) International governance frameworks addressing lost fishing gear already exist, but the current policies have been criticized for being vague, fragmented and incomplete ([3](https://eia-international.org/report/convention-on-plastic-pollution-essential-elements-fishing-gear/?ref=blog.indecol.no)). Therefore, the upcoming global treaty is a unique opportunity to comprehensively address ALDFG or ghost gear, which is often recognized as the deadliest type of marine litter through entanglement and entrapment. These impacts pose an undeniable threat to both commercially important species, as well as charismatic keystone species of marine ecosystems. When it comes to entanglement of marine megafauna such as whales, seals, sharks, seabirds and turtles, the only plastic treaty that can purposefully address this impact is one that encompasses plastic losses from the fishing industry. The solution to the complex issue of ghost gear naturally requires measures at both local and global scales. For example, new gear designs as well as gear labeling and reporting schemes can be useful to minimize and keep track of losses at sea, while convenient access to waste management systems is a prerequisite in order to achieve better handling of derelict gear. Additionally to the upcoming plastic treaty, a UN agreement from last year pertaining protection of marine biodiversity beyond national borders is also a promising starting point for reducing pollution from fishing activities in the high seas ([4](https://news.un.org/en/story/2023/06/1137857?ref=blog.indecol.no)). In this regard, international coordination and collaboration can hopefully be a crucial driver to both limit future inputs, but also to incentivize actions for retrieving the already existing hazardous debris, which otherwise will outlive us and potentially entangle and catch marine animals for years to come.

From agricultural machines to advanced technology like graphics processors and renewable energy tools like solar panels, machinery is ubiquitous. Machinery capital is essential, yet research in [Environmental Science & Technology](https://pubs.acs.org/doi/10.1021/acs.est.3c06180?ref=blog.indecol.no) indicates that its manufacturing process alone contributes to significant carbon emissions and entails heavy consumption of metals and materials. ## The Carbon and Material Footprint of Machinery In this study, we integrated input-output analysis with dynamic material flow analysis to understand the material and carbon footprints of machinery. In 2019, machinery production required 30% of global metal production and contributed to 8% of global carbon emissions. Moreover, from 2000 to 2019, the metal footprint of machinery stocks grew at a rate twice that of the global economy. The complexity of machinery's role in climate change is highlighted. On one hand, machinery is crucial for climate mitigation technologies and services, but on the other, its production and lifecycle are heavily carbon-intensive. ![](https://blog.indecol.no/content/images/2023/12/image.png) Figure 1\. Metal footprints in machinery and equipment capital stock: in 2019, 2000 and changes in the global share. ## Key Findings and Global Implications A detailed breakdown of the carbon footprints associated with machinery production is presented, along with a regional comparison of carbon, material, and metal footprints within machinery and equipment capital stock. Industrialized countries use 2−4.5 tons of metals per capita to build their stock of machinery and equipment, while many developing countries dispose only of a tenth of that amount. To illustrate the global implications and scale, we spotlight key countries. Around 2008, China's total machinery capital stock, indicated by the metal footprint of machinery stock, exceeded that of the United States. By 2019, it had doubled, though its per capita level still remained at only half of that in the US. The growth rate and absolute increase in developing regions significantly surpassed those in developed countries. Consequently, the share of advanced economies in the global material footprint of machinery stock declined from 51% to 34%. This shift was more pronounced in machinery used in production industries (extraction, manufacturing, and machinery), where in 2019, advanced economies accounted for only 24% of the worldwide share, a decrease from 45%. ## Towards a Circular Economy We discuss the concept of depreciation in the financial sector and its discrepancy with the actual service life of physical machinery. For instance, a five-year-old car might lose half its value on the book, but more than 50% of such cars are still in use. It indicates that the physical assets continue to serve long after their book value has depreciated. Understanding the relationship between a machine's tangible value and its environmental impact is vital for both financial and environmental strategy. For instance, in scope 3 emissions accounting, the methodology a company uses to calculate capital-related emissions greatly affects reported data and shapes responsibility allocation. Our findings point towards an essential transition: as physical machinery stocks saturate, new machinery can increasingly be built from metals recycled from retired machinery. This shift is vital for moving towards a more sustainable and circular economy, where waste is minimized and resources are reused efficiently. ![](https://blog.indecol.no/content/images/2023/12/image-1.png) *Figure 2\. Metal footprint embodied in machinery stock: Comparison of the physical world vs. financial present values. The metal footprint is calculated by using the survival curve (SV) and depreciating rates (DP) for different countries.* ## Conclusion Machinery holds a dual role in the battle against climate change. As an essential component of industrial and daily life, its environmental impact is also significant. The presented analysis lays the foundation for future research and policymaking. It underscores the importance of devising strategies that balance machinery's utility with its environmental footprint. This serves as a call to action for industries and policymakers to harmonize the advantages of machinery with the imperative of sustainability.

In [this publication](https://www.sciencedirect.com/science/article/pii/S0269749123019371?via%3Dihub&ref=blog.indecol.no), Naiara Casagrande, affiliated with the ATLANTIS project, has developed effect factors for additives that are used in plastic products. The results of the 25 calculated effect factors varies by several orders of magnitude from 20.69 PAF·m3·kg−1 for diethylphtalate to 11081.85 PAF·m3·kg−1 for 4-Nonylphenol. ### Knowledge gained on marine litter through beach cleanups URL: https://blog.indecol.no/knowledge-gained-on-marine-litter-through-beach-cleanups/ Last updated: 2026-07-06T23:57:13.000Z Our coasts and beaches are more than just beauty. They are home to many animals and plants. They also provide jobs and income for communities and people, such as fishermen, tour guides, and hotel owners. Despite of their importance, these ecosystems are under pressure from the huge amount of marine litter in recent decades. Marine litter hurts the ecosystem service in many ways. It can be dangerous for marine life, at the same time, it can also be harmful for human and society. Beaches, where the land meets the sea, often are more exposed. Marine litter on the beach not only pose the danger of physical injury but also reduce the recreation value for locals. In my research of plastic´s impact on recreation value, we looked through 10 international organizations who initiate cleanups, trying to find what is most common items searched and found in the beach cleanups. Those organizations are: (1) [OSPAR](https://repository.oceanbestpractices.org/handle/11329/1466?ref=blog.indecol.no) (2) [Blue Ocean Society Beach Cleanup](https://www.blueoceansociety.org/beachcleanup/?ref=blog.indecol.no) (BOS) (3) [World Cleanup Day (LDIW)](https://www.worldcleanupday.org/about?ref=blog.indecol.no) (4) [Surfrider beach cleanup](https://www.surfrider.org/pages/beach-cleanup-activist-guide?ref=blog.indecol.no) (5) [#EUBeachCleanup](https://oceans-and-fisheries.ec.europa.eu/eu-beach-cleanup%5Fen?ref=blog.indecol.no) (6) [Ocean conservancy coastal cleanup (TIDES)](https://www.coastalcleanupdata.org/?ref=blog.indecol.no) (7) [Marfo Beach clean-up](https://www.marfo.no/en/strandrydding/?ref=blog.indecol.no) (8) [Marine LitterWatch (MLW)](https://www.eea.europa.eu/themes/water/europes-seas-and-coasts/assessments/marine-litterwatch/data-and-results/marine-litterwatch-data-viewer?ref=blog.indecol.no) (9) [EMODnet](https://emodnet.ec.europa.eu/en/marine-litter?ref=blog.indecol.no) (10) [Global cleanup campaign (oceanic society)](https://www.seaturtleweek.com/plan-your-cleanup?ref=blog.indecol.no) First, I looked at those organization´s guidelines and data cards, and word cloud of the 20 most common items they searching for was drawn. The font suggests its frequency. ![](https://blog.indecol.no/content/images/2023/12/wordcloud_item.png) Figure 1.Word Cloud for plastic items in reporting cards Then, many organizations often group similar items into a category, such as plastic, metal, glass, etc. Another word cloud by frequency of each category is created. ![](https://blog.indecol.no/content/images/2023/12/wordcloud_catagory.png) Figure 1.Word Cloud for plastic categories in reporting cards Last, we retrieved coastal European countries´ beach cleanup from source (6). Ocean conservancy coastal cleanup (TIDES). It suggested in many country/year, the most common items by number were cigarette butts and small pieces of plastic or foam. ![](https://blog.indecol.no/content/images/2023/12/Piece_Cigarette-butts.png) Figure 3\. Share of Different Plastic by pieces in European countries While beach cleanups offer invaluable insights into the issue of marine litter, they are not without their limitations. Factors such as location, frequency, season, and scale can all significantly influence the results. Moreover, the lack of universally agreed-upon reporting guidelines often leads to discrepancies in the quality of reports. Therefore, it’s essential to view the data from beach cleanups with caution and a critical eye. They are a piece of the puzzle, but not the entire picture. ### New ATLANTIS publication out URL: https://blog.indecol.no/new-atlantis-publication-out/ Last updated: 2026-07-06T23:57:20.000Z Our paper about the MarInvaders WebTool has finally been published in Ecosphere. We have built a tool to visualize the database that we compiled previously. We collected data for 966 aliens pecies for 225 marine ecoregions and also included over 1500 species that are threatened by invasive species. While the trend regarding sitribtion of invasive species remains the same as seen in previous publications, our database is more comprehensive and allows to visualize both invasive and threatened species in the sma e regions. We plan to update the WebTool regularly. ### "Plastic day" / "Plastdagen" in Trondheim URL: https://blog.indecol.no/plastic-day-plastdagen-in-trondheim/ Last updated: 2026-07-06T23:57:28.000Z Guest author: Gabrielle Häberli Time: 12th of October 2023 Location: Dokkhuset, Trondheim. ## Plastics – incredibly useful Plastic is an umbrella term describing a wide range of materials often perceived as "non-natural". They date back more than 100 years although their production only really "took flight" as an industry in 1907 when Leo Baekeland created Bakelite. [Plastics have had a significant influence on human development](https://plasticseurope.org/plastics-explained/history-of-plastics/?ref=blog.indecol.no) and today it's nearly impossible to avoid contact with plastic in our day-to-day life; it's everywhere around us. Some technologies started only after plastics were invented but are today no longer in need of plastics, like celluloid used in photographic film. Other sectors have experienced massive developments after the invention of plastics, as we see in: The healthcare industry, due to plastic's ability to isolate and so keep hygiene; rubber car tires, for friction and so safety; plastic bottles and other storage equipment, which immensely improved shipping; and the use of plastic as a light and durable material generally improved many inventions from hiking equipment to airplanes. But not unlike nuclear power, this great invention comes with a responsibility. If plastics are not properly - we'd dare say perfectly - managed then they have immense environmental impacts. Plastics that are lost to the environment are practically impossible to retrieve and, in addition, [many plastic products are estimated to take 500 years to decompose](https://wwf.org.au/blogs/the-lifecycle-of-plastics/?ref=blog.indecol.no). In light of this, both industry and science have a responsibility to the sustainability of the plastic industry, and a small piece of a very large effort was witnessed at "Plastdagen". ![](https://blog.indecol.no/content/images/2023/11/image.png) Macroplastic turning to microplastic on an island in [Mausund](https://www.euronews.com/green/2022/01/17/norway-s-most-beautiful-nature-reserve-is-being-destroyed-say-researchers?ref=blog.indecol.no). The 2023 edition of Plastdagen took place on the 12th of October, uniting in Dokkhuset (Trondheim) people from industry, academic and scientific research, to open the discussion around sustainable solutions to tackle plastic pollution. Karl Klingsheim, the organizer of the event, catered a mix of lectures, posters exhibition and one-on-one discussions, all motivated by a common goal: contribute to a greener future. The issue was addressed through a diverse range of relevant angles. Multiple companies and organizations contributed, bringing insight into UN treaties, waste management, project funding, etc. NTNU research also had its share of the spotlight, represented by PhD students from the ATLANTS and MAPLE projects. ## In the perspective of ATLANTIS and MAPLE As many of our most vigilant readers by now probably know, [ATLANTIS](https://atlantis-erc.eu/?ref=blog.indecol.no) is a taskforce determined to introduce *marine biodiversity impacts* in the framework of Life Cycle Impact Assessments (LCIA, [see the book on "Life Cycle Impact Assessment" by Hauschild and Huijbregts, 2015](https://doi.org/10.1007/978-94-017-9744-3?ref=blog.indecol.no)). Philip from ATLANTIS presented how both macro- and microplastic pollution affects marine biodiversity and through this also global climate change when emitted to end up in the final environmental "sink" of plastics: The ocean. ![](https://blog.indecol.no/content/images/2023/11/MicrosoftTeams-image--3-.png) Philip presenting the perspective of ATLANTIS The impacts in focus from macroplastics were: Entanglement, ingestion, invasive species spread, and damage to tourism and culture. Especially marine mammals birds have been observed to entangle themselves in plastics which leads to laceration, strangling, and so death. Animals of all sizes, birds and zooplankton, have been witnessed to ingest plastics which has both toxic effects and also slows feeding of actual nutrients leading to sickness and starvation. And invasive species, especially barnacles and mollusks, have been seen "hitchhiking" on floating plastic debris and thereby reach pristine environments where they bring havoc and imbalance heavily impacting the welfare of the native species communities in recipient ecosystems. And then plastics are ugly to look at which diverts tourists from coastal societies whose economy is reliant on tourism, especially now that pollution and over-exploitations of different kinds have eradicated their marine source for food. The impacts from microplastics mainly deal with the growth inhibition of phytoplankton which sends cascading effects through the marine trophic web, especially primary producers. Among other things, phytoplankton aggregates in lumps to micro-plastic particles which for any individual not on top of the aggregate decreases the amount of sunlight needed for photosynthesis. In addition, such lumps may sink to deeper waters rendering the same effect. Since [primary production is the greatest natural "engine" for carbon sequestration](https://www.sciencedirect.com/science/article/pii/S0025326X19308689?ref=blog.indecol.no), the inhibition of these species has an indirect, but significant, impact on climate change. ATLANTIS is therefore developing impact assessment methods for the above mentioned issues to use in LCIA. In midst of the excitement and appreciation of the many different perspectives and ideas to combat plastic pollution, we also noticed the use of life cycle assessments (LCA, the framework including LCIAs) on plastic products which underlines the importance of our work. For the evaluation of product and policy environmental assessments and also environmental product declarations (EPDs), LCA becomes an increasingly more important and popular tool. But for plastic products, some of the most devastating impacts are not yet considered in the modelling framework and so decisions are made without the inclusion of these factors. We warned people at Plastdagen that while LCA is improving and expanding fast to include such impacts, we are not yet there. We encourage the use of LCAs, but we must remember what each model is able to assess and not forget to also qualitatively assess what our models cannot yet do. When asked when the ATLANTIS models are ready for use, we answered honestly: We cannot say how long it will take for these models to mature into a state where they are robust enough to be used for industrial and political decision-making - but we already know the answer to solve this plastic crisis without the models. Stop the excessive and unnecessary use of plastic wherever possible even if a product system becomes economically more costly. ![](https://blog.indecol.no/content/images/2023/11/20231012_125956.jpg) Ahmed (MAPLE) presenting his Material Flow Analysis quantifying plastic flows in the Norwegian economy. This is something that Ahmed emphasized when he presented his work at Plastdagen. He developed a Material Flow Analysis (MFA) model that quantifies the plastic flows in the Norwegian economy and further estimates the amounts that leak to the environment. He showed that the Norwegian waste management is already highly efficient, and further cuts in plastic leakages entails a consumption reduction of certain products, such as consumer packaging and agricultural products. He also highlighted tire wear rubber as the major source of microplastic pollution, and current policies and regulations overlook this source. Ahmed also presented an estimation of the plastic additives that get released alongside plastic products. Many of the substances he included are toxic, understudied or poorly regulated, which shows the other dimension of the plastic crisis. His work was submitted for revision in a peer-reviewed journal, and we hope to see it published in the very near future. Ahmed’s PhD is part of [MAPLE (Marine Plastic Pollution: Environmental Impact and life cycle scenarios)](https://www.ntnu.edu/web/sustainability/maple?ref=blog.indecol.no) project, funded by NTNU’s interdisciplinary sustainable initiative, where his role is to assess the sustainability performance and develop scenarios for a more sustainable Norwegian plastic economy. ![](https://blog.indecol.no/content/images/2023/11/MicrosoftTeams-image--4-.png) Gabrielle (MAPLE) presenting the impacts of plastic on marine microbial communities. Alongside Ahmed in the MAPLE project, Gabrielle Häberli, a PhD student in the biology department at NTNU, works on the relationship between marine plastic debris and microorganisms. She presented her work on the impact of plastic on marine microbial communities and impact of microbial communities on plastic fate. This dual point of view is necessary to assess risks on biodiversity, as well as development of strategies for regulation and mitigation. Elucidating the complex plastic-microbe interactions is key to modelling impact and fate scenarios. Gabrielle aims to provide a better understanding of microbial colonization dynamics on marine plastic debris and potential plastic biodegradation in Trondheimsfjord, by using a mix of molecular and microscopy techniques. Hopefully adding to the scarce understanding of what we call the plastisphere (or plastic microbiome). In addition, Gabrielle provided important distinction in the terms used to describe plastic biodegradation. As microbes have an apparent role in ocean plastic mitigation, and overall fate, the distinction of terms such as “degradation” and “mineralization” are needed to give the public the correct understanding of microbe-plastic dynamics, and potential biotechnological solutions for the future. ATLANTIS and MAPLE projects are examples of current efforts aiming to fill the research gaps in the plastic pollution crisis. We hope more opportunities, like Plastdagen, will allow us to reach and sensibilize a wider public with regard to this critical issue. ### Dagsvik silent on the detection limit of their instrument URL: https://blog.indecol.no/dagsvik-silent-on-the-sensitivity-of-their-method/ Last updated: 2026-07-06T23:57:36.000Z This blog post was publihed in Norwegian in [forskersonen.no](https://forskersonen.no/debattinnlegg-global-oppvarming-klima/dagsvik-svarer-ikke-pa-de-viktige-sporsmalene/2272008?ref=blog.indecol.no) In his [response](https://forskersonen.no/debattinnlegg-global-oppvarming-klima/edgar-hertwich-sitt-innlegg-tyder-pa-manglende-forstaelse-for-var-metodiske-tilnaerming/2269342?ref=blog.indecol.no) to [my critique](https://forskersonen.no/debattinnlegg-global-oppvarming-klima/gamle-og-forkastede-klimateorier-i-ssb-notat/2267533?ref=blog.indecol.no) of Dagsvik and Moen’s [discussion note](https://www.ssb.no/natur-og-miljo/forurensning-og-klima/artikler/i-hvilken-grad-endrer-temperaturnivaet-seg-pa-grunn-av-klimagassutslipp/%5F/attachment/inline/5a3f4a9b-3bc3-4988-9579-9fea82944264:f63064594b9225f9d7dc458b0b70a646baec3339/DP1007.pdf?ref=blog.indecol.no), John K. Dagsvik fails to address my fundamental points: **What is the sensitivity of the model they used?** I asked about the sensitivity of the method they had employed: How much would the climate need to change for them to detect an impact that could be ascribed to CO2? JD did not respond to that point. JD confirmed elsewhere that their study had not ascertained that CO2 had not influenced the climate, it only found that the analyzed temperatures had not changed enough to be detected by the employed method. This is why I would like to repeat my question: What is the sensitivity of the method? In his response, Dagsvik explained: *A purely statistical (stochastic) model was used to analyze a selection of temperature series, each by itself. Using more weather stations does not make the analysis more or less precise.* This statement confirms my suspicion that they tried to detect climate change in the temperature records of an individual weather station. > Seeking to detect global climate change in the records of an individual weather station is like trying to ascertain a pandemic by observing one individual's body temperature. In that context, I would like to point to the discussion note: *From these estimates and the formula above it follows \[..\] that the upper bound of the temperatures in July in Oslo becomes 51.0 degrees Celsius. The highest temperature ever recorded in Oslo is 35 degrees (21 July 1901), which we note is substantially lower than the upper bound. \[..\] Thus, even in a stationary model with normally distributed variations, such as FGN \[the model employed by JD\], quite extreme temperature realizations are possible.* That means, in other words, that **the temperature in Oslo would need to rise well above 51 degrees to be detected as abnormally warm**. And JD would need several such extreme temperatures to ascertain that the climate had changed. If deviations by tens of degrees, or even several degrees from the historical record are required for the method to indicate there is something going on, we could not expect it to confirm climate change, given that the IPCC reports an increase in global average temperature by just over one degree compared to the preindustrial level. The quotes strengthen me in my suspicion that the method used was really not suitable to investigate the research question that was posed. In that case, the failure of the method to detect a systematic temperature rise would hence indicate the method's insufficient precision rather than the absence of climate change. ![](https://blog.indecol.no/content/images/2023/10/bilde.png) **What has fluid mechanics to do with temperature analysis?** I criticized the discussion note for a literature review that was off-topic, i.e. it was irrelevant to the research they presented. JD did not respond to this critique. I also showed that their literature review [repeated standard climate-denialist talking points](https://blog.indecol.no/climate-sceptic-talking-point-published-by-statistics-norway/) based on outdated references and had ignored newer evidence that showed the assertions to be false. While JD provided some arguments with newer references that try to salvage their earlier assertions, this does not address the issue of the irrelevance of these points to the study they had conducted. I shared Dagsvik's texts with my colleague [Simen Åndøy Ellingsen](https://www.ntnu.no/ansatte/simen.a.ellingsen?ref=blog.indecol.no), professor of fluid mechanics. He sums up a lengthy email to me with: *"The argument is irrelevant. These properties of Navier-Stokes' equations, which are inherently correct in principle, do not change the fact that climate models provide predictions good enough to inform best response decisions. It's a common misconception. The flow is chaotic locally, but statistically it is quite predictable; Just think of the flow in a stream – if you look from a few centimetres away second by second, it's chaos, but if you take a step back, you'll see a calm current that changes slowly. Call it weather vs. climate, if you will. Navier-Stokes describes the first image, but it's the latter that's interesting here. Take-home message: Solving Navier-Stokes' equation in full detail is here completely uninteresting, nor necessary to make useful predictions."* Ellingsen also points out that similar approaches to Navier-Stokes' equations are used in almost all practical applications, and form the basis for today's design of aircraft, ships, cars, processor fans, oil pipes, wind turbines, hydropower and much, much more. Since Dagsvik and Moen clearly do not understand fluid mechanics, why do they see themselves competent to assess these complex arguments about atmospheric physics which they reproduce in a one-sided manner in their note? To argue even that atmospheric physicists are wrong in their use of fluid mechanics? Given the lack of understanding of the science they are discussing, and the lack of relevance to the question they are investigating, Dagsvik and Moen should remove paragraphs 3-6 and parts of paragraph 1 of the discussion note. ### Climate denial published by Statistics Norway URL: https://blog.indecol.no/climate-sceptic-talking-point-published-by-statistics-norway/ Last updated: 2026-07-29T18:08:15.000Z It is very surprising that the agency entrusted with the offical statistics, [Statistics Norway](https://www.ssb.no/?ref=blog.indecol.no), has published the manuscript “[To what extent are temperature levels changing due to greenhouse gas emissions?](https://www.ssb.no/natur-og-miljo/forurensning-og-klima/artikler/i-hvilken-grad-endrer-temperaturnivaet-seg-pa-grunn-av-klimagassutslipp/%5F/attachment/inline/5a3f4a9b-3bc3-4988-9579-9fea82944264:f63064594b9225f9d7dc458b0b70a646baec3339/DP1007.pdf?ref=blog.indecol.no)” by Dagsvik and Moen, given the dubious content and character of that work. Statistics Norway says[ it is normal practice in social science to release preprints of scientific work](https://www.ssb.no/omssb/ssbs-virksomhet/nyheter-om-ssb/diskusjonsnotat-fra-ssb-skaper-debatt?ref=blog.indecol.no), but their release gives this manuscript the impemature of peer-reviewed and officially approved information. However, the argument that the agency had no choice but to release work that one of their (retired) scientists was involved in, does not hold. The manuscript does not constitute a research paper but a piece of propaganda. The agency does not publish anybody else's opinion pieces. **It should be easy for Statistics Norway to recognize that it is not a scientific manuscript given the following characteristics**: \* Since Isaac Newton’s famous dictum ‘I stand on the shoulder of giants’, it has been a standard scientific practice to review prior work in the same domain before presenting one’s own work. The manuscript does not contain such a review. Given their question, the authors would otherwise have had to account for the chapter ‘[The Human Influence on the Climate System](https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC%5FAR6%5FWGI%5FChapter03.pdf?ref=blog.indecol.no)’ of the latest IPCC report, which on 100 pages provides a very thorough treatment of the matter. That assessment is based on the full body of scientific work, and just the list of sources used fills 30 pages. \* Instead of reviewing prior analyses of temperature trends and their connection to greenhouse gas concentrations, Dagsvik and Moen promote several alternative, false theories, as well as assertions and remarks that are irrelevant to the matter at hand. \* The report repeats several points from the book[ 'the cold sun](https://scilogs.spektrum.de/klimalounge/fritz-vahrenholt-und-sebastian-luening-beharren-auf-abkuehlung/?ref=blog.indecol.no)' by German ex-politician Fritz Vahrenholt, published in 2012, which promoted the theory that the solar cycle determines the climate of the Earth. The book was characterized by a biased presentation of the literature, where several sources were [misquoted](https://environmentalfootprints.org/blog/germany-solar-influence-on-climate-in-public-spotlight?ref=blog.indecol.no). Vahrenholt further concluded with certainty that the temperature up to 2020 and beyond would [drop.](https://twitter.com/rahmstorf/status/1491015574390214659?ref=blog.indecol.no) Haven't Dagsvik and Moen realised that [the opposite](https://berkeleyearth.org/are-temperatures-this-summer-hotter-than-scientists-expected/?ref=blog.indecol.no) has happened? ![](https://blog.indecol.no/content/images/2023/09/Prognose_KalteSonne.jpg) Prognosis of global temperatures in "the cold sun" and actual development. Figure credit: [Stefan Rahmstorf](https://www.stefanrahmstorf.com/en/?ref=blog.indecol.no) \* Dagsvik and co-author Moen further cite astrophysicist [Henrik Svensmark's ](https://en.wikipedia.org/wiki/Henrik%5FSvensmark?ref=blog.indecol.no) theory that cosmic rays through processes in the upper atmosphere affect the climate on Earth. The theory was tested in climate research's [most expensive experiment](https://en.wikipedia.org/wiki/CLOUD%5Fexperiment?ref=blog.indecol.no), at CERN about 10 years ago. The experiment showed that the mechanism described by Svensmark was too [weak to affect the temperature of the earth's surface](https://www.science.org/doi/10.1126/science.aaf2649?ref=blog.indecol.no). It is surprising that Statistics Norway cites old theories that have been tested and rejected. ![](https://blog.indecol.no/content/images/2023/10/image.png) [Summary of the 2016 paper in *Science*](https://www.science.org/doi/10.1126/science.aaf2649?ref=blog.indecol.no) on the results of the CLOUD experiment which tested Henrik Svensmark's theory of cloud formation and its impact on the global climate. \* Retired economist Dagsvik asserts that atmospheric physicists do not understand that the weather is chaotic. In fact, atmospheric physicists teach this in their introductory courses. They also understand fundamental fluid dynamics and have developed an approach to solve fluid-dynamic equations for an open system. *It is inappropriate for a scientific manuscript to contain disparaging assertions about other, far-removed disciplines and fields of study*. **Have temperatures increased?** ![](https://blog.indecol.no/content/images/2023/10/image-1.png) **Frequency of extreme temperatures: a** Percent of the global land area with monthly temperatures above different sigma-thresholds in any calendar month (averaged over the year). Sigma is the standard deviation of the mean monthly temperature during the period 1951-1980\. **b** Global annual mean series (1880−2020) of the ratio of observed local monthly temperature records on land compared to those expected in a stationary climate.

Their statistical model, however, does not use any data on greenhouse gases. After they have asserted, in their review, that multiple factors affect temperatures including natural variations, their model does not take such natural influences into account. It is completely useless to investigate the question they have posed. According to the model, the maximum temperature that can be expected within the normal range on a random July day in Oslo is 51 degrees Celsius! *Only when it gets even warmer will the model allow that temperatures are outside the normal range*. An instrument that is so insensitive cannot be used to evaluate theories of climate change, because these do not suggest that temperatures should have increased by tens of degrees because of past greenhouse gas emissions. It should be noted that Dagsvik and Moen could have used their model to investigate the question of whether observed temperatures are inconsistent with the theory that temperatures have increased. This would be closer to answering the question they pose in the title of their manuscript. However, they have not done that. **Like medicine, climate science relies on multiple lines of evidence** When assessing whether the climate is changing due to human influences, the IPCC conducts a much more sophisticated analysis that takes multiple indicators such as temperature records in many locations, elevations, and media, sea level rise, ice melting, and shifts of seasons into account. Imagine you go to the doctor because you have fever and feel unwell. Given a body temperature of 38 degrees, Dr. Dagsvik would assert that this was in the normal range and send you back to work. A real doctor would instead look at your throat and nose, hear your lungs, maybe send a test of your saliva to the laboratory. She would make a diagnosis based on all these different observations.

Given the unscientific character of the content, they put their own reputation on line.** P.S.: It is somewhat ironic that Dagsvik and Moen criticise the statistical analysis of temperature data through climate researchers and claim that they can do better. Fifteen years ago, physics professor at Berkeley, Richard Muller, did. His [Berkeley Earth ](https://en.wikipedia.org/wiki/Berkeley%5FEarth?ref=blog.indecol.no) project received big money from climate skeptics in the U.S. coal industry to disprove the hypothesis that the Earth's temperature has increased. The team improved both the dataset and statistical method. The analysis showed that warming was even stronger than what the Intergovernmental Panel on Climate Change had determined at the time. Berkeley Earth also publishes a [guide for climate skeptics](https://berkeleyearth.org/wp-content/uploads/2022/12/skeptics-guide-to-climate-change.pdf?ref=blog.indecol.no), showing the limits of climate science knowledge in a simple manner. ### An emergency brake for the climate URL: https://blog.indecol.no/an-emergency-brake-for-the-climate/ Last updated: 2026-07-29T18:08:18.000Z Originally published in [forskning.no](https://forskersonen.no/eu-fn-global-oppvarming/uten-a-brabremse-klimautslippene-kan-vi-passere-15-grader-rundt-2030/2245728?ref=blog.indecol.no). Translated from Norwegian. The climate crisis is here. We are experiencing possibly the warmest year in human history. Record-warm oceans are contributing to historic floods in China, Greece, Slovenia, and Norway. [Forest fires ruined Northern Europeans’ summer holiday](https://www.nrk.no/ytring/et-forsvar-for-reiseguidene-1.16495281?ref=blog.indecol.no) and devastated Hawaii’s Mau Island.

There is broad political support for the 1.5°C target in the Paris Agreement, in Norway as in Europe. Politicians promised voters to take strong action to reduce emissions. Emissions of 350 billion tonnes suffices to raise the concentration of carbon dioxide in the atmosphere to the level where there is a 50% probability that the average temperature will reach or surpass the threshold of 1.5 degrees Celsius above the pre-industrial average. Last year, carbon emissions from energy and cement production alone reached a record 37 billion tonnes, according to [Global Carbon Project](https://www.carbonbrief.org/analysis-global-co2-emissions-from-fossil-fuels-hit-record-high-in-2022/?ref=blog.indecol.no). Without abruptly slowing down, we pass the 1.5 degrees emissions budget by around 2030, and summer this year gives us a taste of what an average year will look like then. The European Union has through the [presidency of Ursula van der Leyen](https://commission.europa.eu/strategy-and-policy/priorities-2019-2024/european-green-deal%5Fen?ref=blog.indecol.no) done a lot for climate protection. The EU’s and Norway’s target for 2030 is to reduce emissions by 55% from 1990 levels. The EU had achieved a reduction of 32% by 2021, Norway by just [4%](https://miljostatus.miljodirektoratet.no/tema/klima/norske-utslipp-av-klimagasser/?ref=blog.indecol.no). The EU Climate Law of 2021 requires the Union to set an emission target for 2040 and prepare a budget of accumulated emissions for the period 2030-2050\. This is the objective by which future policies in industry, energy, transport, and agriculture will be governed. Norway is obliged to follow EU rules in several of these policy areas and has in the past also chosen to set the same emission targets. [The EU climate advisory board, ](https://climate-advisory-board.europa.eu/news/eu-climate-advisory-board-recommends-ambitious-2040-climate-target-and-urgent-transitions-for-the-european-union?ref=blog.indecol.no)anchored in the Climate Law, has now submitted proposals for both a target for 2040 and an emissions budget for 2030-2050\. In our work on the 2040 target, we have considered how the global emission budget of 350 billion tonnes can be fairly distributed among the world's eight billion inhabitants, and the feasibility of emission cuts.

Three of four railway lines from Trondheim we blocked by land slides following storm 'Hans' in August 2023 and one key railway bridge on the Trondheim-Oslo line collapsed. The UN Framework Agreement on Climate Change from 1992 already laid down guidelines for equitable distribution of emission cuts. Everyone has a responsibility to reduce emissions, but it is necessary to differentiate both according to who causes how much emissions and the ability to implement reductions. Philosophers and researchers have worked out different distribution principles and investigated what this means for the distribution of the global emission budget. All principles based on historical emissions show that rich countries and China have used up their share of the emission budget, and then some. Only if we disregard who was responsible for past greenhouse gas emissions are European countries still allowed to emit more. In other words, the EU and Norway must reduce their emissions to zero as quickly as possible and prepare for carbon removal afterwards. At the same time, no one can be obliged to achieve the impossible. The global energy and climate models used by the Intergovernmental Panel on Climate Change ([IPCC](https://www.ipcc.ch/sr15/chapter/chapter-2/?ref=blog.indecol.no)) have long struggled to find measures that reduce emissions fast enough to limit warming to 1.5 degrees. But no one predicted that solar and wind energy would become so cheap, that electric cars could compete with fossil-powered vehicles so quickly, and that developing countries could increase their welfare with so relatively less energy use than rich countries did. The advisory board has examined two thousand different emission scenarios from many models. Three scenarios were selected as examples. These scenarios now serve as our basis for analyzing the necessary emissions reductions in different sectors of the economy. The scenario analysis shows that there are different ways of reaching the 1.5°C target. Scenarios that achieve the 1.5°C target involve a radical phasing out of fossil energy sources and a rapid expansion of solar and wind energy. All scenarios involve reduced consumption of meat and transport services, accelerated development of renewable power, use of nuclear power, carbon capture and storage, and hydrogen, but in different composition and scope. In the scenarios that achieve the 1.5°C target, emissions in 2040 are only 5-10% of emissions in 1990\. The EU's accumulated greenhouse gas emissions between 2030 and 2050 are 11-14 billion tonnes. This is not more than four years’ worth of the current annual emissions of 3.5 billion tonnes per year. After 2050, the EU will have to remove some carbon dioxide from the atmosphere to remedy old sins. The advisory board recognises that a reduction of 90-95% by 2040 compared with 1990 is a tough climate target. If we reduce less, then we rush past 1.5 degrees of warming. It will be difficult to stop emissions later, while at the same time we are battling the consequences of the climate crisis, such as refugee flows, floods, and heat waves. We must stop emissions! The EU is on the right track, and the goals proposed by the Council are achievable, but require a faster pace of change. Norway is a good illustration that not all countries are as well positioned as the EU. Stronger action is needed there.

Copenhagen. ### Experience from the research visit in Norway URL: https://blog.indecol.no/experience-from-the-research-visit-in-norway/ Last updated: 2026-07-06T23:58:02.000Z From May to August 2023, Naiara Casagrande was invited to join the Industrial Ecology Programme at NTNU as a visiting PhD student. Naiara is a Ph.D. student at NOVA University of Lisbon, in Portugal, and conducts research at the Marine Research and Environmental Risk Lab (MARlab), which is part of the Marine and Environmental Sciences Centre (MARE). The research visit at NTNU was part of a collaboration with ATLANTIS. Naiara has been working online with Francesca since the beginning of her Ph.D., and the research visit was an excellent opportunity to work closer with Francesca’s group. In general, her thesis is a contribution to the integration of impacts caused by plastic pollution in the aquatic ecosystem into the life cycle assessment (LCA) methodology. Naiara is focused on the impacts of additives released from plastic pollution to water, causing ecotoxic effects in the aquatic ecosystem. Working at IndEcol, she could exchange knowledge with the group to define the next steps of her research. Since the first week at IndEcol Naiara, could exchange information with other researchers on anthropogenic activities affecting biodiversity loss. During the research visit, she presented her work, and there was an analytical discussion about it. This discussion, in addition to meetings and small talks with other Ph.D. students working on similar topics, brought meaningful new inputs to the research from a LCA perspective. She also had the opportunity to present to IndEcol how the lab tests at MARLab assess the ecotoxicological effects of plastic pollution on aquatic biodiversity. These presentations provided an excellent exchange of information and collaboration between her and the researchers working on LCA and the impacts of plastic pollution on the aquatic ecosystem. This research visit also improved her skills in data analysis by helping her learn more about the different software used by the group for this purpose and the application of artificial intelligence (AI) in research. As a result, she could further improve the process of analysing data and then apply it to her future model. During her stay in Trondheim, Naiara could learn how the municipal waste collection and management system works, especially related to plastics. Furthermore, small talks with colleagues working on industrial ecology generated discussions related to the problem we are facing with plastic pollution, helping to expand the way we are thinking of solutions to advance sustainability research. Besides the scientific learning Naiara could participate in the social activities of the group. ### The ISIE2023 conference in Leiden URL: https://blog.indecol.no/isie2023-leiden/ Last updated: 2026-07-29T18:08:20.000Z People with interests in the field of Industrial Ecology from around the world gathered in the city of Leiden (Netherlands) from the 2nd to the 5th of July. They met for the conference set up by the International Society for Industrial Ecology (ISIE). The overall theme was "transitions in a world of turmoil". For some, this mainly stirs up thoughts of sectoral transitions like in the energy, construction, or mining sector. Others think of cultural transition. I thought of my own transition, specifically how I perceive and evaluate problems of global climate change and biodiversity loss that, especially in our field IE, we are faced with on a daily basis. I assume everyone thought a bit about all of it. As the theme states, we are "in a world of turmoil", turmoil is (according to Oxford Languages) "a state of great disturbance, confusion, or uncertainty." In this case I would exchange the "or" with an "and". This turmoil became very visible as the conference symbolically ended with the greatest storm ever recorded in the Netherlands for summer months. Two people died (not related to the conference), and the country was on code red shut down most of the day. But most staff and visitors of the conference went through the storm to shelter in the university building Kamerlingh Onnes Gebouw (KOG - mind your pronunciation), wherein the search for a better way forward was unfaltering. ![](https://blog.indecol.no/content/images/2023/07/--Remko-de-Waal---ANP-AFP.webp) ![](https://blog.indecol.no/content/images/2023/07/20230705_111355.jpg) ![](https://blog.indecol.no/content/images/2023/07/20230705_111430-2.jpg) From left: Aftermath of the storm Poly in the Netherlands (© Remko de Waal / ANP/AFP), walking outside the hotel Golden Tulip towards the conference, our colleagues Dafna and Daniel coming back from morning sessions drenched to the bone. A better way forward has for a long time been painted in the colors of improving technology and efficiency. But at the ISIE2023 we saw a remarkable focus on "limits to growth" and/or "de-growth", planetary boundaries, and critique of the Gross Domestic Product (GDP) as indicator of welfare, all being mentioned by multiple keynote speakers. This indicates a life-style transition, a rather hot topic on the conference. ![](https://blog.indecol.no/content/images/2023/07/20230704_124731.jpg) Only vegetarian food was served. No questions were asked, it is simply the new norm. With that in mind, the transition to a more sustainable life-style must be mapped, and I suspect it to be a more complex issue than that of the transition to green energy - alone in terms of being more cross-disciplinary from humanities to natural sciences. That being said, IE is in the eye of the storm (as it was quite literally). We can evaluate the potential impacts from industry and human societies to ecosystems, and I saw some working with feedback models - so industry to ecosystems, and then ecosystems to industry impacts as well. I felt a recognition that we are part of the ecosystem, not the user of it. ![](https://blog.indecol.no/content/images/2023/07/20230704_113931.jpg) Keynote speech in the university halls I have been inspired by how much complexity our modelling tools can sometimes encompass, although admittedly I sometimes think that maybe we are overcomplicating our quantitative approach when in fact the problem is something else. Many asked: "How do we get word to the policy-makers?". Greta Thunberg's name was mentioned more than once, she has said: "For more than 30 years, the science has been crystal clear. How dare you continue to look away..." And here we were, repeating our science, but somehow our message does not go through well enough. Maybe science is sometimes too dull to attract the interest of the masses. One alternative shot at getting the message out there was setting up the "creative abstracts". Here people sang, animated, painted, and poetically rhymed out their work. At NTNU we made a board-game where the player must balance between meeting energy-demands and avoiding biodiversity impacts on an island in the midst of green transition and growth. And that won a 1st place for Dafna Gilad's creative group. 0:00/1×The creative abstract deliverable from NTNU was a teaser-video of our developing board game. From NTNU, Francesca Verones also managed to set up a special session focusing solely on "Biodiversity Loss and Impact Indicators in LCA \[Life Cycle Assessment\]", stealing some of the typical spotlight from climate change and energy transition. And then we, the "biodiversity enthusiasts", expanded our reach outside of LCA as Jan Borgelt presented results of an input-output (IO) study. ![](https://blog.indecol.no/content/images/2023/07/20230703_145806-2.jpg) ![](https://blog.indecol.no/content/images/2023/07/MicrosoftTeams-image--1-.png) From left: Jan Borgelt presenting his work on "The exotic species footprint of traded commodities" at an input-output session.

As we were in the midst of the mindboggling problems we ask ourselves to solve, the pressure of their urgency, and the frustrations of seeing almost any trendline continuing towards damnation, we took a break. On the 4th of July many attendants met for drinks and food in the Naturalis Biodiversity Center for a rather unique opportunity to cheers with the long extinct T-rex. ![](https://blog.indecol.no/content/images/2023/07/20230704_223840-1.jpg) ![](https://blog.indecol.no/content/images/2023/07/IMG-20230707-WA0006-1.jpg) ![](https://blog.indecol.no/content/images/2023/07/IMG-20230707-WA0014-1.jpg) From left: A skeleton of the Tyrannosaurus rex, two IndEcol colleagues having a good time, industrial ecologists from around the world having a good time.

The report, commissioned by the Norwegian Society for Nature Conservation, allegedly shows that pressures on global biodiversity caused by Norwegian consumption have tripled since 1995. It is true that much of the SINTEF report summarises research articles in international journals, including articles from industrial ecology at NTNU. However, Sjølie criticises an analysis of Norway's contribution to nature loss that is not elucidated in the underlying reports. *Third-party data should be used with care* The articles referred to examine global conditions, and where Norway is a small piece of the global economy. They relied on the EXIObase [database](https://exiobase.iedl.no/?ref=blog.indecol.no#/exiobase) which describes the world's economy and resource use with many millions of data points. Our research group has collated the data from different sources and used balancing calculations to produce as consistent a picture of the whole as possible. We cannot take responsibility forquality one of some datapoints. Data on agriculture, which the [UN Food and Agriculture Organization](https://www.fao.org/faostat/en/?ref=blog.indecol.no) has collected from member states, has some gaps and input errors.

Foto: Edgar Hertwich *Loss of nature varies with place of production* Sjølie argues that it must be wrong that Norway's contribution to nature loss has increased, while the EU’s contribution has decreased. However, this is not a reasonable comparison because[ Norway import half of the foodstuffs](https://www.faktisk.no/artikler/z873q/hvor-selvforsynte-er-vi-egentlig-med-mat?ref=blog.indecol.no), while the EU is largely self-sufficient with the exception of animal feed and fruit imports from southern countries. Biodiversity loss from agricultural production varies depending on location and cultivation method. It is precisely the point of the [impact assessment methods](https://lc-impact.eu/?ref=blog.indecol.no) co-developed at NTNU to take such regional variations into account. There is generally more loss in biodiversity from agriculture in tropical countries because biodiversity there is greater to start out with. Coffee production, for example, leads to high nature loss. Depending on a year's harvest and adjustment in import rules, countries of origin of Norway’s imports can shift from year to year and produce large variations in nature loss. Given Norway's import dependence, it is quite possible that both nature loss and its development are different from those of the EU. *Biodiversity footprints are knowable, but research on Norway is lacking* On behalf of the [Swedish Environment Agency](https://www.naturvardsverket.se/en/international/research/the-environmental-research-fund/research-efforts-community/policy-relevant-indicators-for-consumption-and-environment-prince?ref=blog.indecol.no), NTNU has worked with the [Swedish Central Bureau of Statistics](https://www.scb.se/hitta-statistik/statistik-efter-amne/miljo/miljoekonomi-och-hallbar-utveckling/miljorakenskaper/pong/statistiknyhet/miljorakenskaper---miljopaverkan-fran-konsumtion-2017/?ref=blog.indecol.no) to compile and quality assure an environmental account for [Sweden's consumption](https://www.prince-project.se/?ref=blog.indecol.no). We haven't done anything similar for Norway, and neither has Sintef, to our knowledge. However, we know that the balancing calculations affect small countries’ numbers more, since the calculations minimizes the aggregate error. In the starting year of the database, 1995, there are larger gaps in the UN's agricultural data than later. Data from 2020 onward is not based on statistics, but on economic projections from the IMF. Thus, it should not be regarded as empirical, and it is not correct to compare 1995 with 2020 or later. [The alarming message posted by the](https://naturvernforbundet.no/nyheter/slik-gar-vi-fra-forbruksfest-til-baerekraft/?ref=blog.indecol.no) Norwegian Society for Nature Conservation has inadequate scientific support. I believe that Sjølie's critique is appropriate, even if he is mistaken in several points. He is correct in saying that SINTEF presents the data and calculation results as conclusions without providing the necessary scientific assessment or interpretation. Research used in public debate must withstand that kind of critical review. ### The Legacy Footprint of Capital URL: https://blog.indecol.no/the-legacy-footprint-of-capital/ Last updated: 2026-07-06T23:58:25.000Z by [Ranran Wang](https://www.universiteitleiden.nl/en/staffmembers/ranran-wang?ref=blog.indecol.no#tab-1) and [Edgar Hertwich](https://www.ntnu.edu/employees/edgar.hertwich?ref=blog.indecol.no) Manufactured capital assets, such as buildings, machinery, and transport equipment, play a pivotal role in driving economic development and human progress. Yet, a common misconception pins greenhouse gas emissions and resource extractions mainly on short-term consumption. New research published in the [Proceedings of the Academy of Sciences](https://doi.org/10.1073/pnas.2218828120?ref=blog.indecol.no) (PNAS) shows otherwise, and how the manufacture of long-lived assets continues to intensify global inequities from three critical perspectives —capital access, the environmental burden of this capital accumulation, and economic gains within the global asset supply chains. ### Unmasking the Legacy Environmental Footprint (LEF) By 2019, global manufactured capital accumulated since 1970 resulted in significant environmental costs. These costs include the emission of 254 GtCO2eq (five times the annual emissions in 2020), as well as the utilization of 31Gt iron ore, 24 Gt copper ore, 507 Gt non-metallic minerals, and 23 Gt wood. Furthermore, the production of these assets cumulatively caused 650 million disability-adjusted life years (DALYs) in adverse health impacts. This legacy environmental footprint reveals the substantial historical costs represented by the capital stock that is used every day to deliver services and produce goods. The study constructed the LEF pyramids to reveal the dynamics of manufactured capital accumulation across low- to high-income economies. China, in particular, experienced exponential growth in LEF between 1995 and 2019, surpassing the combined LEF growth of Brazil, Russia, India, and South Africa. Developed economies maintained a steady increase in LEF over time, modest in relative terms but larger than the increases LEF per person seen in less-developed economies. Hence, the gap in available capital assets between rich and poor countries is growing. ![](https://blog.indecol.no/content/images/2023/06/iron_ore_extraction_1970-2019.gif) The Legacy Iron Footprint as it developed over time. The figure shows the accumulation, starting from investments in 1970. ### Tracing LEF from Production to Consumption Manufactured capital accumulation relies heavily on international supply chains, leading to the outsourcing of environmental pressures and impacts. The study showed that a significant portion of legacy material extractions and human health damages occurred in nations other than those where the capital stocks were accumulated. Developed economies, in particular, had substantial overseas impacts, highlighting a double burden for less-developed economies that provided the raw materials but received a smaller proportion of economic gains. The study also traced the environmental impacts of manufacturing assets to their use in economic sectors and final consumption. Structures, machinery, and transport equipment were identified as significant contributors to legacy greenhouse gas emissions and human toxicity. From the consumption perspective, the majority of the global LEF (about 60-70%) is attributable to four purposes: shelter (including housing, heating & cooling, and house furniture and appliances), public administration and security, health, and mobility. Between an average consumer in developed and less-developed economies, the LEF difference is the narrowest for iron ore extraction (133%) and largest for wood extraction (555%). The most significant gaps between developed and less-developed consumers are potentially due to larger floor areas, complex building practices, and generally larger administrative states in developed economies. ![](https://blog.indecol.no/content/images/2023/06/Sankey.jpg) Illustration of how GHGs were emitted in different decades to make various assets that are used today in various industries to satisfy the consumption in developed and less developed countries. From [PNAS](https://doi.org/10.1073/pnas.2218828120?ref=blog.indecol.no) ### The Urgency of Sustainable Investments As adequate nutrition, sanitation, health care, security, and access to clean water and energy in poorer countries depend on continued investments in manufactured capital, understanding the resource and environmental impacts of this accumulation is crucial. The trade-off involved between the environmental costs of producing capital stocks and the social benefits of the services provided by this capital is a core dilemma for sustainable development. The LEF per gross value added of production (LEF/GVA) provides a new metric for assessing sustainable investments as it tracks the additional environmental costs incurred by a producer when adding an extra unit of manufactured assets. Unlike flow-based metrics considering direct or indirect impacts in a given year, the LEF-based metric isolates capital environmental efficiency from operational environmental efficiency. The significant variations in LEF/GVA across economic activities highlight addressing resource efficiency, reducing environmental intensities, and promoting circular economy practices can contribute to mitigating the environmental toll of manufactured capital accumulation. ### Conclusion The study's findings underscore the high environmental costs associated with global capital accumulation. The legacy environmental footprint (LEF) provides a comprehensive measure of the historical material extractions and environmental impacts embedded in the current stock of manufactured assets. The research emphasizes the need for policymakers, businesses, and society to consider the long-term environmental consequences of manufactured capital investments. By addressing the resource and environmental challenges associated with manufacturing, we can work towards sustainable development that benefits present and future generations. ### Lead authorship for upcoming IPBES report URL: https://blog.indecol.no/lead-authorship-for-upcoming-ipbes-report/ Last updated: 2026-07-06T23:58:34.000Z Francesca Verones was selected as lead author for the upcoming IPBES report on Biodiversity and business.

Metals are omnipresent in our society and crucial for its functioning. However, we rarely purchase and use metals directly as individuals, but instead use it indirectly through our consumption of other goods. The metals are then either embodied in the goods we purchase (e.g., laptops, cars, home appliances etc.) or used in the supply chain of other goods (e.g., agriculture machinery in food production). The consumption of the most important metals has increased faster than GDP. However, metal production is energy and carbon intensive, both at the production site and in the upstream supply chain. In our work we investigate how different technological and socioeconomic drivers have helped increase or decrease the carbon footprint of primary metal production in the period from 1995 to 2018\. A better understanding of these drivers and how they have developed historically provides an empirical base for developing policies targeting carbon footprint reductions in metal production and their supply chains. ![](https://blog.indecol.no/content/images/2023/05/Picture1.png) Figure 1: Global metal production, gross domestic product (GDP), and population growth rates since 1995\. GDP is in constant 2005 prices. Sources: British Geological Survey (metals production statistics), EXIOBASE (GDP), and UN WPP (population). ## What should you know? The drivers investigated in this study were *emissions intensity of the energy supply*, *energy efficiency of metal production*, *metal consumption intensity* (tons metal consumed per unit of GDP in a country), *affluency (*GDP per capita), *population composition*(share of global population living in different regions), and *global population*. Improved energy efficiency of metal production has had a notably impact on decreasing the carbon footprint of metals. This is potentially due improved production technologies and economies of scale, which has been observed in the steel industry (Figure 2a). The decrease in carbon footprint by improved energy efficiency is however complete offset by increasing affluency, global population, and emissions intensity of the supply chain. Affluency and population growth have historically been strongly coupled to increasing carbon footprint. However, the emissions intensity drivers shows that the energy fuels used in the supply chain of metal production have become more carbon intensive since the turn of the century. ![](https://blog.indecol.no/content/images/2023/05/Picture2.png) Figure 2: Montgomery (LMDI-I) decomposition of the GHG emissions in the upstream supply chain of metal production triggered by the consumption of metals in different regions. (a) Global decomposition with metal consuming regions in stacked bars. (b) Regional decomposition with metal groups in stacked bars. The factors in the decomposition are either 6-year aggregates (emissions, energy, and metals) or averages (GDP, population). Note: In (b) the subplots have different y-axis ranges. ## What can you take away from it? There is a need for a complete system thinking when it comes to policies targeting carbon footprint of metals. Policies need to consider the complete supply chain of the goods we consume to effectively reduce emissions. There are multiple levers to push and pull, as well as trade-offs to be considered due to the complex supply chains. E.g., lightweighting cars might reduce the amount of metal used in the product, but if the lightweighting-technology makes the metal production for the car more energy and carbon intensive, no net reduction may be achieved. High-income regions appear to have successfully decouple their metal use carbon footprint from increased affluency, especially due to improved energy efficiency and reduced metal consumption intensity (Figure 2b). Although, it is only the case in the last 6-year period of the study, and it is not clear whether they are able to continue the decoupling trajectory if affluency keeps increasing.

Apart from team building and social activities, the aim was to hold the midterm evaluations of 8 PhD students of the Industrial Ecology Programme, among them Fei Song and Philip Gjedde from the ATLANTIS project. Every PhD student at the IV faculty of NTNU has to deliver a progress report, give a scientific presentation and have a discussion wit a review committee when they are approximately half-way through their PhD. Both Fei and Philip gave excellent and inspiring presentations, explaining their progress. They were able to present complex topics, such as ecosystem services and the use of ballast water in a didactically valuable manner, so that also non-experts could follow and enjoy the learning experience. The following discussion showed that both of them were able to reflect about the uncertainties and values of their approaches in a thoughtful manner. Both of them have several manuscripts that are close to submission and we are excited to submit them soon for review and then hopefully are able to publish them soon on the ATLANTIS webpage! Historic shirts can bring older football stories back into everyday discussion as the difference between authentic and fan styles can shape how a shirt is used. Discussions about retro shirt collecting give collectors a way to compare value, comfort, and emotional meaning. For people following national team history, [replica football shirts](https://www.camisetatienda.com/?ref=blog.indecol.no) is a clear search phrase for readers comparing styles and versions.

We have been benefiting from them since approximately 1600 BC when natural rubber was first discovered\[1\]. A polymer is a material that consists of many repeated smaller subunits known as monomers. The way these monomers are arranged results in the formation of different kinds of polymers with distinctive physical and chemical properties. Polymers can be naturally occurring (e.g., silk, natural rubber, wool) or man-made (e.g., thermoplastics, synthetic rubber, silicone). The term “plastic” is used to refer to synthetic (man-made) polymers that are made from nonrenewable organic petrochemicals (e.g., oil and gas)\[2\]. At the moment, thousands of different plastic polymers each with unique chemical properties are being commercially produced\[2,3\]. Different product applications require different chemical and physical properties. Polyethylene terephthalate (PET) and high-density polyethylene (HDPE) for example are commonly used in plastic bottles. Polyvinyl chloride (PVC) on the other hand is strong, lightweight, dense, and resistant to many chemicals, and therefore is used in the manufacturing of pipes. Moreover, each of the different plastic polymers contains different additives and processing aids to enhance performance, many of which are classified as hazardous\[4–10\], but are understudied, or inadequately regulated\[2\]. We have benefitted substantially from plastics\[11\]. For example, it is used in the packaging of food items to make them last longer. Due to its lightweight, plastic also requires less energy when it comes to the transportation of packaged goods. Packaged goods need less plastic material as compared to e.g., glass, since plastic has a high strength-to-weight ratio. With plastic being incredibly versatile, it is used extensively in a wide range of industrial applications and products. Since \~1950 plastic production has increased by 230-fold\[12\], becoming one of the largest man-made materials. With this rapid growth in its production, plastic waste has also been surging since \~1950 (see the figure below), and future trends are not showing any slowdown\[13\]. ![](https://blog.indecol.no/content/images/2023/03/image-7.png) Cumulative plastic waste generation and disposal 1950-2050 with a business-as-usual scenario\[13\] Unfortunately, plastic products are often being mismanaged once they reach their end of life and eventually find their way to the natural environment. In 2015 alone, 4.8-12.7 million metric tons of plastics were released to the ocean only from land-based human activities\[14\]. Once plastics reach the environment, they degrade very slowly since they are derived from hydrocarbons\[15\], leading to an accumulation of plastics in the environmental compartments, and especially in the ocean since it is the last and biggest sink for plastic waste. This has resulted in the formation of marine debris hotspots in the global oceans\[16,17\], and due to the continuous ocean circulation, plastic items can easily be transported over vast distances due to their lightweight and buoyancy\[18\], making it a global issue. ![](https://blog.indecol.no/content/images/2023/03/COLOURBOX13205207.jpg) The presence of plastic in the ocean has tremendous impacts on the marine ecosystems. It can alter the marine carbon cycle and affect the ability of the ocean to sequester carbon out of the atmosphere, which can eventually accelerate climate change and ocean acidification. An estimated 7.8 million metric tons of plastic carbon reach the seafloor every year\[19\]. Furthermore, marine biodiversity is increasingly at risk due to plastic pollution. Marine species can get entangled with plastic items where their movement becomes hindered, or mistake plastic items for food, which gives them a false feeling of satiation, leading to mortality. Over 350 different species have been observed entangled with plastic debris\[20\]. The uptake of plastics by marine organisms could potentially cause the bioaccumulation of plastics and chemical additives, posing a potential risk even to humans through the food web. Plastic fractions have already been found in human foods\[21–23\], human vein tissue\[24\], and stool\[25\]. ![](https://blog.indecol.no/content/images/2023/03/image-5.png) A seal found entangled in a fishing net\[26\] Plastic items in the ocean can also act as a medium for the transport of invasive alien species, which eventually leads to species being introduced to new ecosystems where they can outcompete the native species, and hence cause a decline in the species richness within the ecosystem. ![](https://blog.indecol.no/content/images/2023/03/image-14.png) Species colonizing a plastic bottle\[27\] With this ever-growing trend of plastic waste generation and mismanagement, plastic pollution is expected to increase, posing a serious threat to ecosystems and, potentially, humans. We clearly need to find solutions to address the issue of plastic pollution. Current policies are increasingly emphasizing on achieving increased circularity and recycling of plastic waste. These policies will undoubtedly help in preserving our fossil reserves, but they will certainly not prevent plastics from leaking to the environment. These policies could even potentially lead to increased plastic pollution mainly due to a phenomenon known as “Jevon’s Paradox”\[28,29\]. Jevon’s Paradox states that increased efficiency (in the form of technological improvement) aiming at reducing the environmental impacts in most cases backfire. Take airplanes as an example; as they became more fuel efficient, ticket prices became cheaper, resulting in more people flying and hence led to an increase in the overall environmental impact. In fact, we have already experienced some form of Jevon’s Paradox with plastics throughout their development. The increase in our consumption since \~1950 is a result of plastic production becoming more efficient and cheaper. A higher recycling rate will lead to a further drop in the price of plastics and may even give the consumers the perception that their consumption has no negative environmental impacts, since their plastic waste will be “managed” in an environmentally sustainable way. However, even when looking at plastics within the circular economy concept, achieving full circularity is not an easy task. For instance, plastic polymers lose their quality and strength as they get recycled\[30\], and not all plastic polymers are easy to recycle (e.g., polystyrene) or recyclable (e.g., polyvinyl chloride). The physical and chemical contamination of plastics\[31\] is another barrier that hinders our ability to create a full-blown circular system. ![](https://blog.indecol.no/content/images/2023/03/image.png) A picture showing the extent of plastic pollution found in one of the many islands in Frøya (a nature reserve in Norway) Even in well developed countries with highly efficient waste management systems and high collection rates, plastic items are often found in the environment. In Norway, which is considered an affluent country, a significant share of the plastic items found at the Norwegian coasts are of a Norwegian origin, while the rest come from countries that are also highly developed, such as the United Kingdom, Denmark, and Germany to name a few\[32\]. The picture above shows the extent of plastic pollution found in a nature reserve island located at the outer Norwegian coastline. Accepting the fact that plastic pollution is only a problem of the developing world is an obviously flawed assumption. ![](https://blog.indecol.no/content/images/2023/03/image-1.png) A bird found dead on a heavily polluted island in Frøya (a nature reserve in Norway) The solutions we need rely on a whole systemic and structural change within the plastic system. Beach clean-ups are certainly important, but unfortunately, they are only addressing the symptoms of the plastic pollution issue. We need to prevent plastics from entering the environment in the first place. We need to design products that contain less plastics and ones that last longer. We need to find alternative materials that can replace plastics. We need to monitor the chemicals and additives added to the plastics, and we most importantly need to reduce our consumption. We need policies that aim at reflecting the environmental impacts of plastic products in their prices. If humanity continues with the existing system aiming at increased growth without respecting the biophysical boundaries of the planet, our oceans will soon be full of plastics, outnumbering all the fish, and we will soon exploit all of the fossil reserves, polluting the atmosphere and causing irreversible ecological changes, and as Herman Daly said: *“As the world becomes full of us and our stuff, it becomes empty of what was here before”*\[33\]. > [Ahmed Marhoon](https://www.ntnu.no/ansatte/ahmed.marhoon?ref=blog.indecol.no)[MAPLE](https://www.ntnu.edu/sustainability/maple?ref=blog.indecol.no) ### References: \[1\] Hosler, D.; Burkett, S.L.; Tarkanian, M.J.

In light of this issue, the 15th meeting of the Conference of Parties (COP15) to the [UN *Convention of Biological Diversity*](https://www.cbd.int/?ref=blog.indecol.no) (CBD) was held from the 7th to the 19th of December 2022 in Montreal, Canada. The main result of COP15 is the [final text of Kunming-Montreal global biodiversity framework](https://www.cbd.int/article/cop15-cbd-press-release-final-19dec2022?ref=blog.indecol.no), including four long-term goals to be achieved in 2050, and 23 targets that, if achieved by 2030, should help the party nations towards achieving the long-term goals. In this article we shortly review the history leading up to the COP15 to CBD and how our project team, ATLANTIS, supports the tasks ahead. ## Short history of the UN Convention of Biological Diversity The history of the UN CBD began together with the more known UN *Framework Convention on* C*limate Change* (FCCC) at the [*Earth Summit*](https://en.wikipedia.org/wiki/Earth%5FSummit?ref=blog.indecol.no) in 1992\. Whereas the FCCC focus on combating greenhouse gas emissions, the CBD combats loss of biodiversity by developing national strategies on sustainable use and conservation of biological resources, *i.e.* the sustainable interaction between industry and ecosystems for which we, in our field (Industrial Ecology), develop decision-tools to achieve, *e.g.* integrated assessment models (IAMs), material flow analysis (MFA), input-output analysis (IO), and life cycle assessments (LCAs). The CBD is meant to cover all ecosystems, species, and genetic resources. It also follows the *precautionary principle*, which means that the lack of scientific certainty should not excuse any postponing of measures needed to avoid or alleviate impacts on biodiversity. The Nairobi Final Act entered into force on the 29th of December 1993 with 168 signatures. In its 2nd resolution it mentions to “To **identify components of biological diversity of importance** for its conservation and the sustainable use of its components” and to “**identify processes and activities which have** or are likely to have an **adverse impact on biological diversity**”. Today we have identified [five key drivers of biodiversity decline](https://www.unep.org/news-and-stories/story/5-key-drivers-nature-crisis?ref=blog.indecol.no): Changes in land and sea use, climate change, pollution, direct exploitation of natural resources, and invasive species. To these drivers we have also evaluated which human activities are related and estimated the economic value of biodiversity as our natural resource. This December, 195 countries ratified the Kunming-Montreal Global Biodiversity Framework, along with the EU. Of these, all UN member states have ratified the treaty except the US, although they have made programs for species conservation and recovery. But in between the Nairobi Final Act in 1993 and our current Kunming-Montreal goals, was the equally ambitious Aichi goals that we mostly failed to achieve. ![](https://blog.indecol.no/content/images/2023/02/image-2.png) [WWF's Living Planet Report 2022](https://livingplanet.panda.org/?ref=blog.indecol.no#:~:text=The%20Living%20Planet%20Report%202022,are%20to%20reverse%20nature%20loss.) had identified 5 key drivers of biodiversity decline. The UN’s *“decade on biodiversity”* from 2011-2020 started at the 2010’s *International Year of Biodiversity*, a “celebration of biodiversity” meant to increase the awareness and importance of biodiversity. It coincided with the failure of the 2010 biodiversity target aimed to halt the decline of biodiversity loss – a target that was far from reached. The next targets until 2020 were imbedded in the [Aichi Biodiversity Targets](https://www.cbd.int/sp/targets/?ref=blog.indecol.no). The first strategic goal (A) wanted to “address the underlying causes of biodiversity loss…” which has impacts on the Kunming-Montreal Global Biodiversity Framework agreed in COP15 where the goals now focus on more measurable actions as the causes have now been identified. The other 4 Aichi goals relate to reduced biodiversity pressure, and improved and enhanced ecosystem diversity and services, which were to be achieved through enhanced implementation through better planning, knowledge management, and capacity building. However, we failed to reach these goals, critics state that they were too vaguely formulated. Similarly, the Kunming-Montreal goals regards ecosystem and biodiversity health, halting of species extinctions, and presents biodiversity as a resource valuable to human society that should be used sustainably. But there is a different tone in the Kunming-Montreal goals compared to the Aichi goals. **The progress seen in the Kunming-Montreal goals** Whereas the Aichi targets have been [critiqued ](https://www.reuters.com/business/environment/why-did-past-targets-protect-nature-fail-over-last-decade-2022-12-09/?ref=blog.indecol.no#:~:text=And%20no%20single%20country%20met,were%20deemed%20%22partially%20achieved.%22)because they “included vague language and did not hold countries to specific action”, the Kunming-Montreal goals present more specific goals than seen before, and has both short termed targets (2030) while the goals are long term (2050). [National Biodiversity Strategies and Action Plans](https://www.cbd.int/nbsap/?ref=blog.indecol.no) (NBSAPs) has been made by most participating parties and developed since the beginning of CBD. The NBSAPs are meant help nations carry out the necessary actions needed to reach the Aichi targets and had to be made on a national level to account for the different needs and challenges of different nations. But despite many nations having successfully implemented a strategic framework, the Aichi targets were not reached in 2020 and deemed a failure. Reflecting on what caused the failure, two major perspectives have been considered when setting up the Kunming-Montreal goals: 1\. The Aichi targets were ambitious and inspired parties to make an effort, but they were also vaguely described and mostly with no benchmark to compare progress. One target, target 11, was specific: "By 2020, at least 17 per cent of terrestrial and inland water, and 10 per cent of coastal and marine areas… are conserved…” And indeed 15 and 8 percent was achieved by 2020\. It is a failure, but also a proof of progress. 2\. The Aichi targets left it up to each nation’s environmental ministries to finance the measures needed to reach the targets. Target 20 aims at *substantially* increasing mobilization of financial resources but has no specific value and is also subject to change. Therefore, with the lack of agreement on international economic needs, especially developing countries were unable to build the capacity needed to reach the targets. In the Kunming-Montreal targets you will find more specific and measurable benchmarks. *E.g.,* by 2030, 30 percent of ecosystems are under effective restoration, and 30 percent of areas of biodiversity importance are conserved and managed. And human induced extinctions are halted, establishment rates of known invasive species are reduced by 50 percent in 2030 and tenfold in 2050, and most notably the estimated economic finance gap of 700 billion USD per year is closed. **Time to manage those that “roll up their sleeves”** The UNEP executive director, Inger Andersen, said “it’s time to roll up our sleeves” which could be an almost direct message to Greta Thunberg that *now* we will come to the action. We have spent decades identifying and quantifying the problem, which to be fair should not have been a necessary primer of action, since we supposedly should follow the precautionary principle. Nonetheless, now that there are specific targets with measurable progress and benchmarks, we can at least expect the parties to be held more accountable to their promises. Also, we can add the specific targets to our NBSAPs and evaluate amongst each other, and over time. What history has shown is that specific and measurable targets have led to better progress, and creating these quantifiable targets is what we have now come a step closer to. But new critiques are already in place, amongst others the executive secretary of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES): Dr. Anne Larigauderie. She regrets to have only agreed on the [“30x30”](https://www.euronews.com/green/2022/12/20/global-biodiversity-framework-almost-200-countries-have-signed-but-is-it-truly-historic?ref=blog.indecol.no#:~:text=Almost%20200%20countries%20have%20agreed,induced%20extinction%20%2D%20among%20other%20measures.)pledge, *i.e.* the focus on conserving 30 percent of nature. Whereas some believe to be close to the target already, making this a clearer but non-influential target, the specific formulation of the target was in debate before it was even ratified. For example, the UK believed to have protected 26 percent of their ecosystem area, but the [Wildlife and Countryside Link](https://www.wcl.org.uk/progress-report-on-protecting-land-and-sea.asp?ref=blog.indecol.no) declared that only 3.22 and 8 percent of land and sea area, respectively, is *effectively* protected. Therefore, the formulation of how we indicate progress towards our targets should also be standardized – such work has already been done for the Aichi targets, although only as [guidelines](https://www.cbd.int/nbsap/training/quick-guides/?ref=blog.indecol.no). It is my hope that we will see stronger formulations for the Kunming-Montreal targets in a similar manner but as more than guidelines. On one side we find that specifically quantified targets and goals give way for better results, but simultaneously we must allow nations, sectors, industries, companies, and even households to set their own agenda on how to reach these targets as the best path is context dependent – in other words, we cannot be too specific! Meanwhile, we must ensure that the communication between these entities is transparent and continuous so that they can reach the targets symbiotically rather than in competition. And for this to succeed we must have tools and standards that enable decision-making across these entities. ## How ATLANTIS will help reach the Kunming-Montreal targets ![](https://blog.indecol.no/content/images/2023/02/plastic-whale.jpg) Illustration of a "plastic whale" - to ATLANTIS the whale is a symbol of ecosystem services from our marine environment. Credits: Shutterstock.com The ATLANTIS project is tasked with creating “ecological indicators” in the marine environment specifically focused to be compatible within the “Life Cycle Assessment” framework. Ecological indicators are meant to communicate the impacts of human activities on our ecosystem. Life Cycle Assessments calculate on all energy and material flows between our ecosystems and the “life cycle” of a product or service. Such a life cycle is usually said to be from the first acquisition of resources needed for production (like fuels and metals) until it is discarded (reused, recycled, or disposed of), and includes all steps in between (like use and transport). Thereby, we develop tools that can help decision-makers evaluate if one choice is more sustainable than another and highlight where to invest resources for further development towards a sustainable value chain. This means that each consumer and producer know of the biodiversity impacts related to a strategic choice or product bought, given that the life cycle assessment is clear and transparent, and that the impact on biodiversity is included in the LCA framework when used. ![](https://blog.indecol.no/content/images/2023/02/shutterstock_2249806955.jpg) Representation of a product life cycle. Credits: Shutterstock.com However, the life cycle assessment framework is continuously in development. Whereas impacts related to global warming are considered reliable indicators, indicators on other biodiversity threats are fully missing in the framework. We in ATLANTIS are developing the first indicators for invasive species, and macro-plastic pollution, and we relate these impacts along other impacts to ecosystem services – all for the marine biosphere. This is a step closer to quantify our footprint on two of the five key drivers on biodiversity decline: Invasive species, and pollution. In addition, the impacts are assessed throughout the value chains thereby giving an overview of the impactors in different sectors and industries, allowing for communication between the right stakeholders as the material or energy flows become highlighted in the value chains and so you are able to map relevant connections that needs to be developed to achieve your own target. We are creating all indicators on a regionalised resolution meaning that we differentiate between impacts based on the context of their location. Therefore, you could very well find that you are able to reduce your impacts caused by introducing invasive alien species, by either changing trade routes or communicating to your shipping partners that there are impacts that needs to be alleviated and the change documented. In my personal perspective on life cycle assessment, it is not meant to “stamp” anyone as sustainable or not, but rather it is a tool that allows for better screening and communication of impacts between stakeholders such that we in collaboration can move towards the best sustainable choices. An example related to our Kunming-Montreal goals is [Norway’s NBSAP](https://www.cbd.int/doc/world/no/no-nbsap-v4-en.pdf?ref=blog.indecol.no) stating that: “We are responsible for the environmental pressure Norwegian activities cause outside the country’s borders through trade and investment. Norway’s efforts to reduce pressure from Norwegian activities in other countries are therefore an important part of its national policy for biodiversity at global level.” The mentioned pressures can be found using life cycle assessment, and therefore it is paramount that we include the key drivers of biodiversity decline.

URL: https://blog.indecol.no/consence-on-the-move/ Last updated: 2026-07-29T18:08:25.000Z In 2022, the CONSENCE project was on the move. Literally! As the global coronavirus pandemic eased (-ish), came the first opportunity to attend conferences and share some of our first results! The first stop was the 32nd annual European meeting of SETAC (the Society of Environmental Toxicology and Chemistry) \[1\], which took place between the 15th and 19th of May in Copenhagen, Denmark. Unsurprisingly, I was mostly interested in the niche session about Novel Life Cycle and Sustainability Assessment approaches supporting biodiversity in land and water management. A wide variety of talks explored the impacts of plastics on wildlife, overexploitation of fish, off-shore wind farms on birds, water consumption, or global extinction probabilities. At the conference, I presented our new methodology to quantify the life cycle collision impact of power lines on birds in Norway in a poster. ![](https://blog.indecol.no/content/images/2023/01/Screenshot-2023-01-02-at-4.35.26-PM.png) The poster "Between the Lines": how to quantify the collision impact of power lines Later that year, I attended the Environmental Concerns in Rights-of-Way (ROW) Management conference \[2\]. It is a symposium that takes place every four years (!). The conference aims to provide a forum to discuss the environmental impacts of the ROW. In case you are unfamiliar with the term, the ROW is the treeless corridor in which the power lines stand. The conference occurred between the 9th and 12th of October in Charlotte, USA. ![](https://blog.indecol.no/content/images/2023/01/IMG_4654.jpg) Marshall Park in Charlotte The symposium was focused on the management aspect of the ROW. The sessions discussed vegetation management, drones identifying plant communities, and satellite data detecting hazard trees along the ROW. Regarding nature conservation and ecology, the Monarch butterfly (*Danaus plexippus*), a threatened species in North America, was mentioned regularly in the talks. The species migrates annually from Canada and the USA to Mexico and depends on certain plant species (i.e., Milkweed, *Asclepias syriaca*) to survive \[3\]. The ROWs provide a good habitat for species that need open habitats, for instance pollinators. ![](https://blog.indecol.no/content/images/2023/01/UAA_ROW13-067-Group-scaled-1.jpg) ![](https://blog.indecol.no/content/images/2023/01/UAA_ROW13-017-scaled-1.jpg) ![](https://blog.indecol.no/content/images/2023/01/UAA_ROW13-080-scaled.jpg) ![](https://blog.indecol.no/content/images/2023/01/UAA_ROW13-326-scaled.jpg) ![](https://blog.indecol.no/content/images/2023/01/UAA_ROW13-104-scaled-1.jpg) Pictures from the field trip and the ROW conference \[2\] Indeed, in many cases, we can observe a higher number of species in the ROW compared to the nearby forest. Yet by reducing the forest area, species that dwell mostly in forests will be affected \[4\]. At the conference, I presented the global impacts of power lines on biodiversity, focusing on birds and mammals. We assessed the impact of habitat loss on the ecoregion and country level, showing how the effects of power lines vary across countries, and highlighting the importance of sustainable planning. A conference paper about our research will be published later this year. In February 2023, I will attend the 6th conference of the Norwegian Ecological Society (OIKOS) \[5\]. It will be held at the Norwegian University of Life Sciences in Ås. At the conference, I will talk about our life cycle impact assessment models that quantify two main impact pathways of power lines – electrocution and collision – on Norwegian birds.

The research center is part of Hawai'i Pacific University ([HPU](https://www.hpu.edu/?ref=blog.indecol.no)) and they conduct interdisciplinary research on plastic pollution in the field and their labs. As such, to be hosted by CMDR was an excellent opportunity for me to get a more hands on understanding of local impacts of plastic pollution. As a group of islands situated downstream from the great pacific garbage patch, Hawai'i receives a lot of bouyant plastic debris that have potentially travelled the world before washing up on the local reefs and beaches. Environmental problems related to marine ecosystems also appear to be even more pressing and in focus in a place where the ocean is such a direct part of everyday life, both for leisure and subsistence. Prior to the visit, I had read research papers on plastic debris entanglement of Hawaiian monk seals and the green sea turtles so getting to meet with the researchers that gather this data in the field was a highlight. Specifically, the goal of the research stay was to investigate the issue of sea turtles getting entangled in discarded or lost fishing line. Related to this project, I got to meet with people from organizations such as Hawaii Marine Animal Response ([HMAR](https://h-mar.org/?ref=blog.indecol.no)), and the Marine Institute of Maui Ocean Center ([MOCMI](https://mocmarineinstitute.org/?ref=blog.indecol.no)) who respond to calls from the public about entangled wildlife. Through these connections and by witnessing entanglement injuries and the debris that causes them, I've gained a better understanding of the nature of this issue, which I had only studied in the literature prior to the visit. ![](https://blog.indecol.no/content/images/2023/01/bilde-2.png) Plastic debris in the form of bottles, fishing net and floating fragments During my stay, I also had the chance to learn about the ongoing research at CMDR by joining in on activities ranging from sea turtle necropsies in the lab to international workshops on fishing gear and plastic debris field sampling on beaches. As the issue of plastic pollution is so well known on Hawai'i, it was also not hard to find beach cleanups and other community events for raising awareness on plastic impacts to join outside of the office. This was the second time an ATLANTIS member went to Hawai'i for a research visit - Read about Francesca Verones' stay in [this blogpost](https://blog.indecol.no/research-visit-in-hawaii/). Mahalo! Home, away, and third kits each tell a different part of a club story as fabric, fit, and breathability now matter alongside colour and badge design. Supporters of Chelsea often compare home kits, away kits, and retro designs when discussing the identity of the club. Anyone comparing player and fan versions may find, [Chelsea football shirts](https://www.camisetatienda.com/?ref=blog.indecol.no) is a clear search phrase for readers comparing styles and versions. When fabric details are part of the choice, the paragraph can mention shirts without turning into direct advertising. ### ATLANTIS at the EcoBalance 2022 URL: https://blog.indecol.no/atlantis-at-the-ecobalance-2022-fukuoka/ Last updated: 2026-07-29T18:08:27.000Z EcoBalance is a conference held in Japan every second year since 1994, it has a strong focus on LCA and its application in industries. This year, the 15th EcoBalance, was hosted in Fukuoka, and themed ´Shifting Paradigms with Life Cycle Thinking´. Two members from the ATLANTIS project, me (Fei Song) and my colleague Philip Gjedde, attended the conference and presented our recent research. ![](https://blog.indecol.no/content/images/2022/12/ATLANTIS-at-the-EcoBalance-2022.png) **ATLANTIS´ session and presentations** COVID has hit many conferences in Asia hard, and Japan just lifted its travel restriction in October 2022 after 2-years closing up; thereby, the conference was held as hybrid. On the street and in the conference hall, one can still see many wearing masks. Despite all the difficulties brought by COVID, EcoBalance 2022 still managed to bring together LCA researchers from all over the world. Many scholars attending are from Japan and China; however we also encountered scholars from the Netherlands, Bangladesh, Switzerland, Chile, Australia, Korea, Indonesia, Turkey, etc. The organizer has arranged a variety of activities for all participants to experience a little taste of Japan, including Ninja show, Japanese cuisine lunchbox, and karaoke-networking. ![](https://blog.indecol.no/content/images/2022/12/Ninja-show-.jpg) **The welcome Ninja show at the opening** The conference has a wide coverage: In addition to poster stand, there are max 15 parallel sessions every day, which span from Agriculture, Urban system, Eco-design, to Circularity and Footprints. The focus on LCA application can be spotted everywhere, many posters and presentations are practical research (developing a model to assess a case). Since I am reaching on ecosystem service and culture service is one of potential area, I paid special attention on culture related assessment. Many studies turns out to be very creative, the one left me deepest impression is from Akihiko Tsutsumi of Tokyo City university, who investigated the environmental and social impact of a drama series. Another one inspired me is from Ryusei Murata of Tokyo City University, who managed to estimate Footprint of a traditional festival. ![](https://blog.indecol.no/content/images/2022/12/Interesting-culture-assesment-.png) Two interesting studies of culture related assessment My overall impression of the conference is great! It has advanced tech-support, great coordination and communication, and I got any new ideas for furthering the development of ecosystem service measurement as well as the feedback to my current study. It proven to be a conference worthy participating in the academic sense, with great opportunity to networking as well as discovering Japan.

The LCA discussion fora are held three times a year in Switzerland and cover a large range of LCA-related topics. Participants come from academia, industry, government and non-governmental sectors and this, and the format, which allows room for more dialogue and questions than in normal conference settings, make up a very interesting mix The day was structured into three thematic sessions on the release, the fate and the exposure and effects of plastic and was providing a lot of information on the latest state-of-the-art of addressing marine plastic pollution within life cycle assessment. We were able to invite speakers from a broad background including chemists, consultants, environmental engineers, industrial ecologists, and intergovernmental organizations. Since the discussion forum was organized in a hybrid form, we were able to include speakers from Switzerland, Norway, Denmark, Canada, France, and Peru and three team members of ATLANTIS (Francesca, Marthe and Fei) gave presentations, while Martin acted as an additional moderator. ![](https://blog.indecol.no/content/images/2022/11/Picture1.jpg) We learnt that there is a lot of knowledge about plastic pollution available, especially on microplastics. But at the same time, information is scattered and not standardized, which makes comparisons and inclusions into models hard. And, despite all the knowledge, there are still parts with very limited knowledge, such as degradation rates and the exact behaviour of different plastic items in the ocean. All the slides from the discussion forum are available on the website of the [LCA discussion forum](https://lca-forum.ch/forum?tx%5Fnews%5Fpi1%5BactbackPid%5D=1&tx%5Fnews%5Fpi1%5Baction%5D=detail&tx%5Fnews%5Fpi1%5Bcontroller%5D=News&tx%5Fnews%5Fpi1%5Bnews%5D=3&cHash=6dc3039c1666d9a9ad4bd9b5d0f33075&ref=blog.indecol.no) and video recordings will be available [here](https://video.ethz.ch/events/lca/2022/autumn.html?ref=blog.indecol.no). The culture around football apparel reaches from stadium terraces to everyday collections as fabric, fit, and breathability now matter alongside colour and badge design. Fit and sizing choices can change how a shirt feels for daily wear, display, or collection. For collectors looking at classic seasons, [Barcelona football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) is a natural way to describe interest in club apparel without sounding promotional. For collectors comparing older shirts, the link between design and identity remains clear. ### Participation at the 7th International Marine Debris Conference (7IMDC) URL: https://blog.indecol.no/participation-at-the/ Last updated: 2026-07-16T21:38:01.000Z Naiara Casagrande, who is affiliated with ATLANTIS, attended the 7th International Marine Debris Conference (7IMDC) with a group of research from NOVA University of Lisbon, Portugal. The conference took place from the 18th to the 23rd of September 2022 in Busan, Republic of Korea. This was the first to be held outside the United States dedicated to the issue of marine litter and plastic pollution and was the world’s longest-running international conference series. The conference brought together governments, industry, academia, civil society, and all relevant stakeholders, to discuss the latest science, strengthen collaborations, find solutions and catalyse action to address the urgent, global problem of marine litter and plastic pollution. ![](https://blog.indecol.no/content/images/2022/10/WhatsApp-Image-2022-10-05-at-10.28.24--1-.jpeg) The conference was divided into 9 sessions which included Monitoring; Research; Technology & Innovation; Education, Awareness & Communication; Regulations, Laws & Policy; Circularity & Waste Management; Economics-Financing & Private Sector Engagement; Sea-based Sources; International Collaboration. Naiara presented her research entitled “Life Cycle Impact Assessment perspectives for integration of impacts caused by microplastic in the marine ecosystem” in the session entitled "The future of the science of monitoring". This was an update of how LCA researchers are using data on microplastic pollution in order to address the environmental impacts in the methodology. ![](https://blog.indecol.no/content/images/2022/10/WhatsApp-Image-2022-10-05-at-10.27.41.jpeg) Multiple options for field trips were included in the program at the 7IMDC, organized to occur on Wednesday afternoon. Naiara attended the field trip which included an industry tour at Netspa, Busan Resource Circulation Cooperation Center and the Nakdong Estuary Eco-center. The Netspa is an interesting fibre manufacturer which produces eco-friendly textiles by recycling abandoned fishing nets. Netspa works in partnership with the Busan’s government which establish a system for separate disposal of abandoned fishing nets, while Netspa charges of washing and processing the collected fishing nets. It was a great opportunity to meet this industry and their work on recycling fishing nets as South Korea has a huge fishing industry. On the last day of the conference, attendees were invited by the Ocean Conservancy and Our Sea of East Asia (OSEAN) to a Beach Clean up and data collection exercise. The groups of participants collected microplastic from the Gwanganli beach and registered their characteristics in the CleanSwell app. The conference was also a great opportunity to meet the research community on plastic pollution and the beautiful country of the Republic of Korea. These connections brings new ideas, exchanges of scientific knowledge and creates great memories. National team shirts can hold memories of tournaments, cities, and shared celebrations as fabric, fit, and breathability now matter alongside colour and badge design. The visual identity of Spain often becomes stronger during World Cup runs and continental competitions. For collectors looking at classic seasons, [AC Milan football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) is connected to the way fans compare eras, colours, and shirt details. This approach shows how football apparel can carry history without becoming a sales pitch. ### Marine plastic pollution in Trondheims neighbourhood URL: https://blog.indecol.no/marine-plastic-pollution-in-trondheims-neighborhood/ Last updated: 2026-07-29T18:08:30.000Z When thinking about marine plastic litter, which has become one of the most pressing environmental issues, many people may think first about piles of waste in Africa or Asia. However, the pollution can be closer than you think. As the crow flies it is less than 100 km from Trondheim to [Eider AS Mausund field station](https://www.eider.no/om-oss/?ref=blog.indecol.no), actively combating marine plastic pollution. A key aim of the ATLANTIS project is to quantify the impacts of marine plastic litter, so in September the entire Life cycle impact assessment research group visited the station for 3 days to get an idea of the extent of plastic pollution and to learn about relevant mechanisms behind it. During our trip we first learned from Odd Arne Arnesen (general manager) that the Froan Nature Reserve, one of the largest coastal reserves in Scandinavia, is particularly exposed to marine plastic litter. This is because the several thousand islands of the Nature Reserve are functioning as a net for plastic litter that is transported by ocean current along the Norwegian costs. Since 2017 the team of Odd Arne has the task to clean up the area from plastic and during our trip, we could join the cleanup of one of these islands. During our 30 minutes boat ride, we saw some of the white-tailed eagles and seals that live in the nature reserve, but no plastic. This immediately changed when leaving the boat after arriving at the island. Plastic was everywhere and with every step we were able to spot more plastic. ![](https://blog.indecol.no/content/images/2022/10/overview-plastic.jpg) After a short crash course in plastic collection, each of us was equipped with trash bags. We were all surprised that it was possible to fill several bags within minutes, while almost standing at the same spot. The litter varied from small plastic, over plastic bottles to entire fishing nets, requiring several people to lift them. ![](https://blog.indecol.no/content/images/2022/10/Philip.jpg) We identified that the plastic we found came from all over the world, for example, from Argentina, Malaysia, UK, Spain, Germany Netherlands, but also from Norway. ![](https://blog.indecol.no/content/images/2022/10/Image25.jpeg) In many cases, it was not easy to remove the plastic, because it was already part of the soil. Research from the field station revealed that soil samples in average contained 25% of plastic. In addition, lots of plastic objects where fragile and broke down into small pieces after touching them. Many of these pieces disappeared behind one of the many rocks lying on the islands. We were also surprised to see how far inshore the plastic get flushed by wind and tide. The amount of plastic litter present on the island was so large, that even after several hours one could have thought that we never had started.

Para evitar errores, merece la pena revisar la composición del tejido y su comportamiento con el uso. ![](https://blog.indecol.no/content/images/2022/10/Pond.jpg) As refection we were all astonished how much effort is needed to clean up the plastic, bearing in mind that we only have been on 1 of several thousand islands in the Nature Reserve. This shows that it is first of all important to stop the mismanagement of plastic, to hinder it from reaching the ocean. As the plastic we found came from all over the world, this is a collective effort and not only of the country in which the plastic reaches the shore. However, we must also acknowledge that the local plastic pollution is happening now, and to ensure that the ocean clean-up can keep pace with the amounts of plastic arriving, new technical solutions for clean-up must be developed in parallel. After 2 days we left the Mausund island with mixed feelings. On one side happy as we could experience the beauty of Froan Nature Reserve but on the other side realizing that a serious environmental issue is occurring so close to Trondheim. ### Sharing our research at the 14th ISIE SEM conference URL: https://blog.indecol.no/sharing-our-research-at-the-14th-isie-sem-conference/ Last updated: 2026-07-16T21:38:03.000Z On the 19-21 September, the Socioeconomic metabolism (SEM) section of the International Society of Industrial Ecology (ISIE) organized the [14th ISIE SEM conference](http://www.isiesem2022.org/?ref=blog.indecol.no) in Vienna. Co-organized by the Vienna University of Economics and Business (WU), the University of Natural Resources and Life Science, Vienna (BOKU) and TU Wien (TU), the conference was covering a large variety of topics ranging from urban metabolism, circular economy, modelling of the stock-flow-service nexus to open science. Seven people from our IndEcol team joined the conference: Edgar Hertwich, Meng Jiang, Romain Billy, Fernando Aguilar Lopez, Lola Rousseau, Kamila Krych and Kajwan Rasul. During the conference, IndEcol members presented their latest research. The first one to present right after the opening session was Lola Rousseau, who showed her latest research on urban material stock of roads. The next day, Kamila Krych talked about trends in product lifetimes using dynamic material flow analysis (MFA) and even made some jokes to keep the public entertained since she was given the last presentation slot of the day! During the last day of the conference, Meng Jiang presented his poster on the role of capital investment in China’s material development [\[1\]](https://doi.org/10.1016/j.oneear.2021.12.011?ref=blog.indecol.no). Kajwan Rasul, who is working with input-output data, gave a presentation of the drivers of emissions embodied in global metal consumption. Fernando Aguilar Lopez explained the product-component framework [\[2\]](https://doi.org/10.1111/jiec.13316?ref=blog.indecol.no) allowing to model systems where a failure of a critical component can be the reason for product discard. Fernando showed how this framework could be used for electric cars and batteries. As the very last presenter of this conference, Romain Billy gave some insights from his work on the passenger car market and how its transformation can affect the demand for aluminium and its carbon footprint. ![](https://blog.indecol.no/content/images/2022/10/group_presentations.png) (From left to right) Top row: Meng Jiang, Romain Billy, Fernando Aguilar Lopez - Bottom row: Kamila Krych, Lola Rousseau, Kajwan Rasul The conference was the opportunity to meet the research community on Socio-Economic Metabolism. This topic is gaining more and more interest, and the community is growing quite fast. More than 150 researchers were participating at the conference. It was therefore not possible to network with everyone! This conference was also the opportunity to meet with former colleagues. A reunion picture was taken after the conference dinner (as a side note, all the food provided during the conference was vegetarian and delicious!). ![](https://blog.indecol.no/content/images/2022/10/group_picture-1.jpg) (From left to right) Lola Rousseau, Romain Billy, Sónia Cunha, Kamila Krych, Kajwan Rasul, Edgar Hertwich, Fernando Aguilar Lopez, Stefan Pauliuk, Peter Berrill All the IndEcol members enjoyed the conference. This was even the first conference for several of the early-career researchers. It was a lot of fun as shown on the picture below: ![](https://blog.indecol.no/content/images/2022/10/group_picture_phds_postdoc_funny.png) After the conference, Kamila and Lola chose to travel back to Trondheim by train and bus. A total distance of around 2100 km had to be covered! Door-to-door, around 60 hours were required. By plane, it would have taken only around 9 hours. However, Kamila and Lola were glad to have done such a trip! They could visit some old friends on the way and discover new cities (Hamburg and Copenhagen). They also wanted to reduce the carbon footprint of the trip. A plane trip would have caused around 230 kgCO2eq per person, while a train/bus trip caused around 115 kgCO2-eq. If all the trains were powered by low-carbon electricity, the impact of the trip would have decreased by almost half. \[3\] This shows the importance of both behavioural and technological changes for a sustainable future, which hopefully can soon become the reality, partly thanks to the research we do at IndEcol! ![](https://blog.indecol.no/content/images/2022/10/Lola_Kamila_Train2.jpg) Happy Lola and Kamila at the train station in Hamburg \[1\] Jiang, M., et al., (2022).

The shirt worn during a meaningful run can stay in a fan base for years because the badge and colours can carry meaning long after a fixture ends. Fans following Juventus may notice how badges, collars, and sponsor layouts change the feel of a kit. For collectors looking at classic seasons, [England national team shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) remains a useful phrase within the wider story of football shirts. In conversations about club identity, the shirt works as a cultural object as well as something to wear. ### Research visit in Hawaii URL: https://blog.indecol.no/research-visit-in-hawaii/ Last updated: 2026-07-16T21:38:05.000Z Francesca Verones spent July and August 2022 on Oahu and Big Island, Hawaii for a research visit to continue working on the issues of how plastic pollution is affecting the marine ecosystem. She focused especially on how plastic and invasive species are perceived to impact important marine ecosystem services in the region, amongst others tourism, fisheries and biodiversity itself. Francesca carried out numerous interviews with people from academia, NGOs, federal and state agencies to elucidate the question of how plastic is impacting marine ecosystem services in the region. It was a very interesting and informative stay. While the Hawaiian Islands are contributing to plastic pollution it was very interesting to learn that indeed a large part of the plastic that is found ashore an in Hawaiian waters are being transported here from the Pacific Garbage Patch. This is especially true for things like fishing nets (in the islands fishermen mostly use long-lines) and eel traps. In addition, it makes a big difference how the currents are going, which are, for example, influenced by whether it is an El Niño or a La Niña year. In La Niña years, like this year, there is much less plastic found on the beaches of the Hawaiian islands. Still, even though the beaches on the islands are stunning, especially on the Northern and Eastern sides of them plastic pieces can be found daily. They range from small microplastics to large objects like fishing nets, plastic crates and boxes, flip flops and the odd stuffed animal (we found two of those during our stay here, which were both cleaned and adopted by our children). We did also see the consequences of plastic entanglement first hand. On the beach in front of our house we could observe a green sea turtle who was missing a limb. It may have lost the limb through a shark attack, but the likelihood of it having been entangled in fishing line is large. If turtles get entangled with their flippers, they may be strong enough to rip the fishing line apart and continue swimming, but the fishing line will constrict around their flipper, impacting the blood flow and the turtle may lose its limb (or dies from sepsis). Another time, one of the interviews Francesca was performing on Maui had to be postponed on a very short notice, because the interviewee had to go on a turtle rescue mission. Every year they rescue between 150 and 200 turtles that got entangled in Maui alone, almost 90% of them are entangled in fishing gear. Fortunately, the majority of them can be rescued successfully and be released back to the wild after a rehabilitation period. Now, we return with a lot of data and impressions from this research stay to Norway. Aloha! A football shirt can turn a season, a badge, and a colour scheme into part of supporter identity because it links personal memory with the wider culture of the game. Discussions about matchday clothing give collectors a way to compare value, comfort, and emotional meaning. When personalised names and numbers matter, [football shirts for collectors](https://www.camisetatienda.com/?ref=blog.indecol.no) remains relevant to conversations about collecting, matchday wear, and kit design. When classic designs return, the shirt can carry both practical value and a sense of belonging. ### Early career ocean scientists at conference in St. Johns, Canada URL: https://blog.indecol.no/early-career-ocean-scientists-at-conference-in-st-johns-canada/ Last updated: 2026-07-16T21:38:06.000Z In July, Marthe Høiberg had the pleasure to attend the fourth ICES/PICES Early Career Scientist Conference, taking place in St. Johns on Newfoundland, Canada. As revealed by the name, this is a conference dedicated to giving a platform to young researchers and encourage their involvement specifically in the management and stewardship of our oceans. The main organizers of this conference are the International Council for the Exploration of the Sea (ICES)​ and the North Pacific Marine Science Organization (PICES)​, which this year were hosted by Fisheries and Oceans Canada (DFO). ![](https://blog.indecol.no/content/images/2022/08/a7a3f851-58e2-4630-804f-26daaf12ad69-1.JPG) Marthe Høiberg with new ocean scientist collegues at the conference in St. Johns The conference featured a large variety of topics across scales and many subdisciplines given the broad and encompassing theme of “*Ocean sciences for the future we want*”. The topics of the sessions ranged from biogeochemical cycles, fisheries and biodiversity, to blue economy and novel technology developments, as well as science communication and engagement. Marthe Høiberg had the chance to present her ongoing work on the development of a characterization factor for macroplastic debris impacts in a session called “Science, management and policy for a sustainable and productive blue economy”. To the authors knowledge, this was also the only (sub)session where the topic of plastic debris was addressed, which is in stark contrast to the focus of this year’s [SETAC conference](https://blog.indecol.no/atlantis-at-the-copenhagen-setac-conference/), where ATLANTIS members also contributed. However, this is not unexpected as the ICES/PICES conference has a general ocean sciences theme, and is not dedicated specifically to anthropogenic pollution of our ecosystems. Several other topics of impacts were also addressed, such as those of invasive species in addition to influences on specific species and ecosystems brought about by climate change. Although plastic pollution was not on top of the agenda of the scientific sessions, the conference (through leadership from members of the [Surfrider](https://www.surfrider.org/?ref=blog.indecol.no) foundation) arranged a beach cleanup in a near-by area. This was a great opportunity to give something back to the community that we were visiting, which the majority of the conference participants were happy to take. ![](https://blog.indecol.no/content/images/2022/08/bilde-1.png) Conference participants at Topsail beach after the beach clean-up, organized by the Surfrider foundation and ECOP Canada. Picture: https://twitter.com/ECOPCanada The conference was also a good platform for networking with enthusiastic young scientists from around the world and admiring the impressive marine environment on Newfoundland. Trips were taken to stunning cliffs which are the home to thousands of northern gannets (*Morus bassanus*) and common guillemots (*Uria aalge*), among other species. These two seabird species are known to be subject to plastic debris entanglement, primarily due to the use of pieces of old ropes and nets in the building of the gannets’ nests – however, luckily no incidents were observed on this leisurely visit. Humpback whales (*Megaptera novaeangliae*), another marine species that is known to swim into and get entangled in both active and passive fishing gear, were also observed in the coastal waters of St. Johns. ![](https://blog.indecol.no/content/images/2022/08/threebirds.png) Northern gannets (left), an Atlantic puffin (middle) and cliffs with Common guillemots (right) It became clear throughout the conference that we are rapidly learning so much more about complex aspects of the marine environment, although we need to acknowledge that in some respects we have only “just” begun. In addition, there is a need to place focus on communication of the importance of the ocean, and especially to create engagement among large inland populations that do not have direct and frequent interactions with the marine environment – although we all depend on it. This was highlighted by a keynote speaker who addressed the understanding of how we influence the oceans and vice versa, a concept termed ocean literacy. Lastly, the role of early career scientists in improving equality and diversity in the marine science field and for the future of our oceans was highlighted. A shirt from a famous season can become a shortcut to remembering goals and rivalries when a tournament or league season gives the design a lasting meaning. Discussions about number printing choices help readers think about how a team shirt fits their own use. For people following national team history, [Liverpool football shirt for supporters](https://www.camisetatienda.com/?ref=blog.indecol.no) remains a phrase that sits comfortably in content about football identity. A thoughtful shirt choice keeps the paragraph grounded in football culture rather than simple promotion. ### ATLANTIS at the Copenhagen SETAC conference URL: https://blog.indecol.no/atlantis-at-the-copenhagen-setac-conference/ Last updated: 2026-07-29T18:08:32.000Z Several members of the ATLANTIS project attended the SETAC Europe 32nd annual meeting in Copenhagen this year. We presented our recent progress in the development of characterisation factors for life cycle impact assessment (LCIA) and the MarINvaders toolkit and database, meanwhile we were inspired by other researchers and met associates in the field. For some it was the first time we met physically although we have been working together on projects during the covid-19 epidemic, and with others it was a pleasant reunion. The SETAC conference has brought together environmental scientists, managers, and engineers since 1979\. With its multidisciplinary approach on solving global environmental issues, the launch of the UNEP/SETAC Life-Cycle initiative in 2002 was a natural development of the NPO and this year’s conference was marked by the relevance of LCIAs in solving issues related to chemicals, and especially plastic, in the environment. From the ATLANTIS team, Martin Dorber co-chaired the scientific session on “Novel Life Cycle and Sustainability Assessment approaches supporting biodiversity in land and water management”. With Verones as second author, Koen Kuipers presented the global extinction probability (GEP) model which is some of the work by the global life cycle assessment method (GLAM) working group, with whom ATLANTIS is in close collaboration. We also met other collaborators from GLAM, more precisely from the MarILCA group. ![](https://blog.indecol.no/content/images/2022/06/20220518_100849.jpg) Members of the MarILCA group meeting physically for the first time after the covid pandemic. Other ATLANTIS members presented in the “Life Cycle Impact Assessment modelling and application” session to shed light on the marine environment within LCIA. Marthe Høiberg’s effect factor on macroplastic debris entanglement marked the audience who have mostly been concerned with microplastics but now saw that novel attempts are being made to model the impact of macroplastic. ![](https://blog.indecol.no/content/images/2022/06/IMG-20220518-WA0043.jpg) Marthe Høiberg's presentation on effects of macroplastic debris in the marine environment. We also presented posters about the impacts of plastic debris on marine carbon sequestration (Fei Song) and the MarINvaders database and webtool (Philip Gjedde), the latter is a harmonization of some of the biggest recognized databases on marine species with global coverage and useful for modelling the impacts of invasive species. All the ATLANTIS presentations and posters can be seen on our website: [https://atlantis-erc.eu/](https://atlantis-erc.eu/?ref=blog.indecol.no) ![](https://blog.indecol.no/content/images/2022/06/20220517_154948.jpg) Posters by Dafna Gilad regarding impacts on birds from collision with power lines (right) and Philip Gjedde on the MarINvaders database (left). It was inspirational to see people work with impacts in marine environments. LCA promises to be a holistic tool for sustainability assessment, and people in the LCA community can look forward to characterisation factors related to plastic pollution, fishery, and invasive species being pushed out in the next wave of impact categories in LCIAs.

Las fotografías y la ficha del producto deberían confirmar las instrucciones de cuidado y cualquier límite aplicable a la personalización. My most apparent impressions from the conference relates not only to impact categories but rather how life cycle assessment (LCA) is conveyed in general. There is a call for more transparency and easier access on choices made and data used, meanwhile uncertainty and sensitivity analysis still lack in many LCA’s. Even the ISO 14040 standard which should work as a guideline for all LCAs was criticized as ambiguous. Although basic elements of LCA have room for improvement other branches within the LCA framework are rapidly developing tools to support regionalized and prospective LCIAs meaning that our new characterisation factors will benefit from including these perspectives. My take-home-message from the conference was Marthe’s answer to a purposely provocative, and yet humorous and charming, question by Olivier Jolliet, the lifetime achievement award winner. He asked why we put so much effort into modelling the impacts of plastics when in fact the impact may not be very severe. Marthe responded that such a hot topic must be acknowledged by the scientific community and especially within LCA to answer *if*, *where*, and *how* this emission impacts our environment – this of course is the answer that was sought for, because with the promise of being holistic we must include every potentially relevant impact. ### Two IndEcol professors appointed to International panels URL: https://blog.indecol.no/two-indecol-professors-appointed-to-internationals-panels-2/ Last updated: 2026-07-16T21:38:09.000Z IndEcol is proud to share the latest appointments of professors [Francesco Cherubini](https://www.ntnu.edu/employees/francesco.cherubini?ref=blog.indecol.no) and [Edgar Hertwich](https://www.ntnu.edu/employees/edgar.hertwich?ref=blog.indecol.no) to two new International panels positions.

In particular, it will examine biodiversity-related policies and procedures related to the governance of climate change, adaptation and mitigation strategies, including relevant aspects of the energy system. Further, the chapter will examine financing options and incentives to mitigate and adapt to climate change, while conserving, restoring and sustainably using biodiversity, and meeting relevant global objectives for food, water, and health. Professor Edgar Hertwich has been nominated by the [European Environment Agency (EEA)](https://www.ntnu.edu/indecol/international-panels/eea?ref=blog.indecol.no) to work with 14 other independent senior scientific experts, to provide the European Union (EU) with scientific knowledge, expertise and advice relating to climate change.

Our research suggests decarbonization and growth are independent processes. Delaying one to achieve the other is unnecessary and a wasteful detour.* Nobody in the rich world can blame developing countries for wishing to improve their economic status. We began to industrialize and grow wealthy when we learned to use first coal and then oil to provide us with motive power. [India has been widely blamed for weakening the Glasgow climate agreement](https://www.bbc.com/news/uk-59280241?ref=blog.indecol.no). However, its [coal use per capita is less than Germany’s](https://ourworldindata.org/grapher/coal-consumption-per-capita?ref=blog.indecol.no), and its oil and gas use are much lower. [Sympathetic commentators detect a Northern bias in the negotiation’s exclusive focus on coal, the dirtiest fuel](https://theconversation.com/coal-why-china-and-india-arent-the-climate-villains-of-cop26-171879?ref=blog.indecol.no). Yet, the [tremendous environmental costs of fossil fuel combustion](https://e360.yale.edu/digest/air-pollution-from-fossil-fuels-costs-8-billion-per-day-new-research-finds?ref=blog.indecol.no) are nowhere more apparent than in poor countries, which suffer disproportionately from both air pollution and climate change. When these damages are not reflected in the cost of polluting activities and fuels are subsidized, polluting activities become profitable even if they destroy value and worsen countries. Develop first, clean up later, aptly describes the historical development of rich countries. It is a result of ignorance and the persistent power of special interests. Yet even among experts, there is a widespread belief that emissions first need to rise as countries grow richer before they can go down. In [a recent study](http://dx.doi.org/https:/doi.org/10.1016/j.oneear.2021.10.010?ref=blog.indecol.no), we have analyzed a comprehensive datasets of emissions and economic development covering 73 countries’ carbon emissions and underlying energy and economic variables over 47 years. Our statistical analysis ascertained that economic growth and decarbonization acted independently. If economies relied on fossil fuels, every percent growth raised CO2emissions by a percent. Shifting to cleaner energy, increasing productivity, moving from industry to services, and switching from fuels to electricity contributed to reducing the economy’s carbon intensity. A dozen countries have reduced carbon emissions over extended periods while maintaining economic growth, including Denmark, New Zealand, and Uruguay. They managed this feat through a combination of energy system transition and structural economic change. It is a recipe that can be applied in any country. It has never been easier. Unsubsidized [solar and wind power have become cheaper than fossil power](https://www.irena.org/newsroom/pressreleases/2021/Jun/Majority-of-New-Renewables-Undercut-Cheapest-Fossil-Fuel-on-Cost?ref=blog.indecol.no) but are still hindered by structural barriers, [fossil fuel subsidies](https://www.imf.org/en/Publications/WP/Issues/2021/09/23/Still-Not-Getting-Energy-Prices-Right-A-Global-and-Country-Update-of-Fossil-Fuel-Subsidies-466004?ref=blog.indecol.no), and the power of vested interests. These developments mean that China and India can directly follow in the footsteps of countries that have reduced carbon emissions while maintaining economic growth. Basing economic development on coal and oil and changing the industrial structure afterward is harmful to the environment, economically wasteful, and politically challenging. It is wiser to change the sequence: Clean up first, and then invest in development. We hope the leaders of China and India recognize as much. Their decisions will shape our planet’s future. *Ranran Wang, Valentina Assenova, Edgar Hertwich (2021) “Energy system decarbonization, and productivity gains reduced the coupling of CO2emissions and economic growth in 73 countries between 1970-2016.” One Earth (Cell Press).* [*https://doi.org/10.1016/j.oneear.2021.10.010*](https://doi.org/10.1016/j.oneear.2021.10.010?ref=blog.indecol.no) Al considerar [compra de camisetas de fútbol](https://www.camisetatienda.com/?ref=blog.indecol.no), la decisión resulta más sencilla cuando se confirma la comodidad, el tejido y la frecuencia de uso.

Reducing the use of materials through a more intense utilization of products such as homes or cars, or the construction of lighter and smaller products, will also reduce the energy needed to provide services such as shelter and transportation. Dematerialization hence offers two mechanisms by which emissions can be reduced: the use of materials in production and the use of energy in the operation of these products. In a [comparative scenario analysis](https://www.nature.com/articles/s41467-021-25300-4?ref=blog.indecol.no), we investigated the production, use, and disposal of residential buildings and vehicles in the period up to 2050\. We investigated different strategies that could reduce demand for materials that cause high emissions in their production from natural resources, such as steel, concrete, plastics, aluminium, copper, and glass. These scenarios differ in their assumptions regarding future demand for buildings and vehicles, population size, and climate policies. We focused on residential buildings because they are the most important product of the construction sector, which causes [40% of the material-related carbon emissions](https://www.nature.com/articles/s41561-021-00690-8?ref=blog.indecol.no). We also chose passenger vehicles because they are the most important consumer product of the manufacturing sector, which also contributes another 40%. We found that dematerialization could reduce carbon emissions from residential buildings by 20 to 52 Gt CO2\-equivalent over the entire period up to 2050, depending on future demand and climate policy. Emissions from cars could be reduced by 13-26 Gt during that period (Figure 1, top row). Full implementation of all strategies is assumed by 2040\. In 2050, emissions from buildings and cars would be reduced by one third to two thirds compared to the emissions without the implementation of these strategies. The modeling demonstrates that material efficiency can deliver savings which are in addition to those that can be achieved through a decarbonization of the energy system, increased energy efficiency, and a rising share of electric vehicles. Figure 1 indicates that, in scenarios with a cleaner energy system and more electric vehicles (2°C policy scenario), the percent-wise reduction of emissions due to material efficiency is higher than in no policy scenarios with a moderate rise of renewables and EVs. ![](https://blog.indecol.no/content/images/2022/04/image.png) Fig. 1: Total global cumulative (top) and annual 2050 (bottom) greenhouse gas (GHG) emission reductions of the technical potential of ten industrial and demand-side material efficiency strategies.

For [vehicles](https://doi.org/10.1111/jiec.13067?ref=blog.indecol.no), there are three strategies which provide most of the reductions. These are quite instructive. The first strategy ride sharing, that is, reducing both the number of cars and the distance driven by riding together. Ride sharing, also called carpooling, is now facilitated by apps such as [BlaBalCar](https://www.blablacar.com/?ref=blog.indecol.no)and [Scoop](https://www.takescoop.com/commuter?ref=blog.indecol.no), which match up people who drive with those who need to go the same direction. Ride sharing is different from ride hailing, in which taxi services are provided to riders independent of the transportation needs of the drivers. Ride hailing does not lead to emissions reductions. Another promising strategy is car sharing, which allows a rental of cars by the hour and close to the place of need. Car sharing can be effective in reducing car ownership, but also serves to shift the trips towards other modes of transportation. The third measure is reducing the size and thus weight of vehicles. This often occurs automatically as a result of car sharing: when you rent cars by the trip, you choose a trip-appropriate car. When you buy a car, you size your car for the most demanding trips you plan, be it a ski vacation, taking the neighbors’ kids to a ball game, or pulling a trailer. For homes, we [assessed that floor space per capita](https://onlinelibrary.wiley.com/doi/full/10.1111/jiec.13122?ref=blog.indecol.no) could be reduced by up to 20% compared to the baseline, with a heated floor area in the North of around 30 m2 per capita compared to the current 35 m2in the United Kingdom. Lower floor space not only reduces the amount of building material, but also the energy needed to heat or cool buildings. One measure to reduce floor-space is to have people live in multi-unit dwellings instead of single-family houses. It also reduces operational energy need (because there are fewer outer walls per unit floor space) and increases urban density, which reduces trip distances and increases the attractiveness of public transport and walking/biking over driving. We also investigated the use of wood instead of concrete and masonry buildings. Timber has much lower greenhouse gas emissions and it binds carbon, both of which helps to reduce the CO2concentration in the atmosphere. We considered that there was only a limited supply of wood. To our amazement, we found that if we combine wooden buildings and floor space limits, total wood demand would not increase, but it would shift from single-family homes to apartment buildings, and from industrialized to developing countries. Additional measures we also investigated were increased recycling, reuse of parts, increased product lifetime, increased yields of production processes, and the construction of lighter products. All these strategies offer some savings, and overall, the relative savings in terms of materials are larger than the relative savings in terms of carbon emissions over the life cycle of the products. For recycling, there is already a substantial degree of recycling of metals which saves substantial emissions. Expanding the recycling to other materials has lower benefits than the recycling that already occurs. We also found that product life extensions benefited the climate only when it is applied to efficient buildings and electric vehicles, not to poorer-performing products in the current stock. ![](https://blog.indecol.no/content/images/2022/04/image-1.png) Fig. 2: Impact of material efficiency on material production for passenger vehicles and residential buildings. Full image: [https://www.nature.com/articles/s41467-021-25300-4/figures/4](https://www.nature.com/articles/s41467-021-25300-4/figures/4?ref=blog.indecol.no) Overall, the strategies we investigated would substantially reduce the demand for material production from natural resources (primary materials) by the two sectors. Primary steel demand would drop to a sixth, cement demand to a quarter, and copper demand to half. The primary materials would, to a substantial degree, be replaced by recycled materials. For the metals investigated, at the global level, secondary production would become more important than primary production within the current decade (Figure 2). Next to energy efficiency and low-carbon energy supply, material efficiency is the third pillar of deep decarbonization for these sectors. For those [promoting the circular economy](https://ellenmacarthurfoundation.org/topics/circular-economy-introduction/overview?ref=blog.indecol.no), this would be a significant development. We would like to note that for achieving this switch-over from primary to secondary supply, reducing the overall demand for materials by reducing the demand for new products is at least as important as increasing recycling rates. It means that if we want to achieve a circular economy, we need to look at more than recycling! For this research, we built [a new model](https://doi.org/10.1111/jiec.13023?ref=blog.indecol.no) which traces the product vintages, their composition and operational characteristics from production through use and maintenance to the end-of-life where the materials become available for recycling. This model was first applied to the G7 countries in a report for the [International Resource Panel](https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change?ref=blog.indecol.no), which has informed the formation of the EU’s [Circular Economy Action Plan](https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1583933814386&uri=COM:2020:98:FIN&ref=blog.indecol.no) and its [Renovation Wave](https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1603122220757&uri=CELEX:52020DC0662&ref=blog.indecol.no). The new research shows that, in absolute terms, carbon emissions cuts from dematerialization in developing countries are much larger than those in industrialized countries. Realizing some of these gains is maybe [not trivial in terms of policy innovations](https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change?ref=blog.indecol.no), but it requires no technical breakthroughs. In fact, the technologies are all in place and we can begin realizing the gains identified in our research quite immediately.

As a means towards achieving this goal, we have developed an indicator of potential macroplastic entanglement impact levels, which has now been published in Ecological Indicators: [https://doi.org/10.1016/j.ecolind.2021.108509](https://doi.org/10.1016/j.ecolind.2021.108509?ref=blog.indecol.no) By combining observed entanglement rates from marine mammals, turtles and birds with the species populations’ ranges and exposure to plastic debris concentrations, we have modelled the potentially affected fraction (PAF) of species. This indicator covers the world’s oceans in a spatially explicit manner, and reveals potential hotspots where a larger fraction of species may be exposed to entanglement impacts. The indicator highlights the global issue of entanglements and communicates parts of the damage potential that mismanaged plastic has on marine biodiversity. ![](https://blog.indecol.no/content/images/2022/01/FIG2wordformat-1.jpg) Potentially affected fraction (PAF) of species by macroplastic entanglement This work has also resulted in the first indicator for macroplastic effects that is ready to be applied in impact assessments. Once a separate model that estimates the distribution patterns, i.e. the fate, of a given plastic “emission” has been fully developed, we are ready to incorporate the impact pathway of macroplastic entanglement in LCIA. Football fans often treat kit design as part of the story around a team because matchday clothing can express loyalty without needing many words.

To coordinate research progress, and to ensure that the impacts are modelled in a harmonized way, [Woods](https://www.ntnu.no/ansatte/john.s.woods?ref=blog.indecol.no) et al. developed a new model framework for plastic litter impacts in life cycle impact assessment models, which has been published as open access paper in Ecological Indicators in 2021 ([https://doi.org/10.1016/j.ecolind.2021.107918](https://doi.org/10.1016/j.ecolind.2021.107918?ref=blog.indecol.no)). According to this framework, the impact of plastic litter, and thus the modelling of the impact should start with the release of a certain amount of plastic litter into the environment. But besides the pure amount of plastic also its size matters. Woods et al. highlight that for the impact assessment one should differentiate between three different sizes of plastic litter: macro (5 mm >), micro (5mm - 1µm) and nano-plastic litter (< 1 µm). ![](https://blog.indecol.no/content/images/2021/11/COLOURBOX39177793.jpg) In addition, also the location of the released plastic litter matters. Is the plastic directly released into the ocean (e.g., fishing nets) or into a river, on land or into the air? That implies that it is also important to model the plastic transport between these different compartments and especially how plastic is transported through the marine environment. Also, macroplastic litter can be fragmented and degraded into microplastic over time. Hence, impact models should differentiate between impacts that take place at different time scales, for example, 50 years ago and 100 years into the future. Humans, ecosystems (e.g., species) and structures (e.g., cultural valued sites), which can also be described as receptors, are then exposed to the plastic litter concentration in the marine environment. Species and ecosystems, for example, can be exposed to marine plastic litter via a variety of exposure pathways including ingestion, entanglement, smothering, and the rafting and introduction of invasive species. Each receptor will respond differently to an exposure and ultimately the exposure to plastic litter leads to the potential occurrence of effects. Exposing ecosystems to marine plastic litter can lead to ecotoxic or physical effects on biota and a potential invasive species introduction, which can lead to a potential reduction in species diversity, which ultimately leads to an ecosystem quality damage. In addition, marine plastic can cause damages for other areas, like human health, ecosystems services and socio-economic assets. For socio-economic assets the accumulation of plastic at a beach can reduce options for tourism, leading to an economic damage. ![](https://blog.indecol.no/content/images/2021/11/COLOURBOX39244629.jpg) However, Woods et al. point out that for many of the areas the underlying exposure and effect mechanisms leading to damage are still unclear and that therefore more research and data is needed to fully cover the detailed modelling steps described in their framework. Consequently, they highlight that it is currently more feasible to model impacts that link plastic litter with damage on ecosystem quality. Modelling plastic litter damages on ecosystems is one of the main aims of the [ATLANTIS](https://atlantis-erc.eu/?ref=blog.indecol.no) project. Inside the ATLANTIS project, [Marthe Alnes Høiberg](https://www.ntnu.no/ansatte/marthhoi?ref=blog.indecol.no) is currently working on developing life cycle impact assessment models to quantify the impacts of plastic debris on marine ecosystems and [Philip Gjedde](https://www.ntnu.no/ansatte/philip.gjedde?ref=blog.indecol.no) is working on models to quantify the impacts of invasive species on marine ecosystems. Furthermore, [Fei Song](https://www.ntnu.edu/employees/fei.song?ref=blog.indecol.no) aims to close the research and data gap when it comes to the ecosystem service area, as she estimates the impact of marine invasive species and marine plastic debris on ecosystem services. **Reference:** Woods, J.

Office buildings in hot countries URL: https://blog.indecol.no/green-and-cool-office-buildings-in-hot-countries/ Last updated: 2026-07-16T21:38:15.000Z Office buildings are a special type of buildings, with lots of people and appliances, all producing heat. They usually have big windows that allow lots of sunlight to enter. And while this additional heat can be advantageous on a cold day, it usually means that **office buildings need much more cooling** than residential buildings. In the future, most office buildings are expected to be built in developing countries. These economies are growing, meaning that more and more people will be employed in the service sector, likely increasing the demand for offices. At the same time, developing countries typically have very warm climates! ### The green: greenhouse gas emissions Now we know — office buildings in warm climates are important. But how much do they impact the environment in terms of greenhouse gas emissions? We tried to answer this question in our new study (Krych et al. 2021). We analyzed the life cycle of a building. Actually, not one, but 1000 buildings! Each of them had slightly different characteristics. We considered ten parameters, including climate, cooling system efficiency, and frequency of replacement. The main results can be seen in the figure below. Not surprisingly, the right panel shows that the highest emissions are caused by operational energy use, particularly cooling. But surprisingly, paint pops up as the hotspot of material replacement emissions! The decisive factor is its frequency of replacement, on average every 8 years. ![](https://blog.indecol.no/content/images/2021/11/Figure1.png) Greenhouse gas emissions of: (a) material production and transport, (b) material replacement, (c) operational energy use. Source: Krych et al. (2021). ### The cool: cooling systems Cooling in buildings requires lots of energy, causing greenhouse gas emissions. How do we decrease the emissions while still keeping the buildings cool? Typically, office buildings are kept cool using mechanical air conditioning (AC). But it uses lots of energy! Wouldn't it be better to open the windows to get some fresh cool air and only use the AC when necessary? That's the idea behind mixed-mode ventilation. Our findings suggest that the mixed-mode strategy can offer a **14% reduction of greenhouse gas emissions** on average. By opening windows, we can decrease the environmental impacts of cooling in buildings. Just don't forget to first turn off the AC! ![](https://blog.indecol.no/content/images/2021/11/COLOURBOX19662306.jpg) Photo: [Colourbox.com/PetraD](https://www.colourbox.com/image/facade-of-a-modern-office-building-image-19662306?ref=blog.indecol.no) Read more: Krych, K., Heeren, N., & Hertwich, E.

It is true to some extent, as oceans cover more than 70% of the global surface, and 40% of the world’s population live in coastal areas. Many aspects of our lives interact closely with the oceans: sea-foods provide important nutrition, a mild climate is moderated by oceans, a coastal town can be a perfect holiday destination, coral reefs and mangrove forest provide protection from storms, to just name a few examples. All these examples have in common that they are ecosystem services. These are services that nature provides us humans with and can be distinguished into provisioning, regulating and cultural services, respectively. We are enjoying so many of the marine ecosystem’s services without realizing it! Nowadays, anthropogenic interventions in marine ecosystems is more frequent than ever, and the number and intensity of stressors the marine ecosystems are confronted with keep rising.

Still, in a Life cycle assessment(LCA) context, we know little about the impacts that humans have on marine ecosystem services. My PhD project is part of the ATLANTIS project.

Improving the lives of their citizens will increase the demand for energy and materials — which in turn will make climate change worse.* *It may seem like an insolvable problem. But the combination of clean energy, efficient energy use, and material efficiency can allow the Global South to develop while reducing greenhouse gas emissions,* [*our research shows*](https://www.nature.com/articles/s41467-021-25300-4?ref=blog.indecol.no)*.* Developing countries are gravely exposed to the harms that result from global warming — increased frequency and severity of heat waves, droughts, storms, and floods, as well as sea level rise. While temperatures are increasing more in polar and temperate regions than in the south, it is in the tropics that [wet-bulb temperatures](https://www.cbc.ca/news/science/how-hot-is-too-hot-for-humans-understanding-wet-bulb-temperatures-1.6088415?ref=blog.indecol.no) threaten to surpass a lethal level. It is very much in the interest of poor countries in the Global South to mitigate greenhouse gas emissions. Yet, some politicians and businesspeople see climate change mitigation as a Northern ploy to cheat them out of the opportunity for development. The North developed its infrastructure, buildings, and factories without consideration for the climate. Why should people in the South be denied this opportunity? Well, they don’t need to. Those Southern politicians correctly point out that it is our obligation in the North to take a lead in mitigating greenhouse gas emissions. People in the North have filled up more than their share of the planet’s atmosphere with CO2\. Yet today, the 6.5 billion inhabitants of low and middle-income countries emit more greenhouse gases ([62% of global CO2](https://ourworldindata.org/co2-by-income-region?ref=blog.indecol.no)) than 1.2 billion inhabitants of high-income countries, an improvement over historically even more inequitable emissions. [China’s per-capita emissions have even surpassed those of Europe](https://edgar.jrc.ec.europa.eu/climate%5Fchange?ref=blog.indecol.no). Continued industrialization following a Northern or Chinese model threatens indeed to accelerate climate change. A different development pathway is possible. The South can achieve modest prosperity while reducing its emissions substantially in three ways: They can shift to clean, low-carbon energy sources , increase energy efficiency overall, and [use materials and services more efficiently](https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change?ref=blog.indecol.no), too. ![](https://blog.indecol.no/content/images/2021/09/image-4.png) Contribution of different emission reduction strategies to the reduction of GHG emissions from residential buildings and passenger vehicles in 2050 for the Global South. The two side-by-side bare explore a different sequencing of the reductions. The reductions are applied for three different scenarios, the Low Energy Demand scenario which has a tight limit on activity, the Shared Socioeconomic Pathways SSP1, which is optimistic about climate-friendly development, and the SSP2, which is more broadly in line with current development.

Today, [photovoltaic cells produce the cheapest electricity](https://www.carbonbrief.org/solar-is-now-cheapest-electricity-in-history-confirms-iea?ref=blog.indecol.no) in India, undercutting dirty coal. In East Africa’s Rift Valley, wind power plants can deliver full-load electricity in 60% of the time, which is more reliable than many of the continent’s electricity grids. So there’s no doubt that clean energy offers hope for developing countries. But can clean electricity production can be ramped up quickly enough to replace dirty power plants, as well as to provide for rapid growth? Land-use conflicts arise. The electricity grid needs to be strengthened and expanded. There are high up-front costs. That’s why increasing energy efficiency is also critical. [Energy efficiency](https://www.iea.org/data-and-statistics/data-product/energy-efficiency-indicators?ref=blog.indecol.no) has long been in focus when it comes to reducing energy needs. In powering machines, electric motors are more efficient than combustion engines. LEDs offer the same light as incandescent or oil lamps for a small fraction of the energy. Well-designed buildings require much less or no mechanical cooling. Those savings should help shrink the gap between new supplies of clean energy and overall demand. The third ingredient in this climate policy mix is [material efficiency](https://www.uselessgroup.org/research/materials-systems-analysis?ref=blog.indecol.no). [One quarter of global greenhouse gas emissions are in the production of materials](https://www.nature.com/articles/s41561-021-00690-8?ref=blog.indecol.no). Most material use is in emerging economies, contributing to nine of 11.5 gigatons of the carbon footprint of materials in 2015\. Concrete in new buildings, steel in new machines, factories, and vehicles, copper in new wires. There are many opportunities to reduce material use, and most of them can be found in emerging economies. In China today, [the average lifetime of a building is 23 years](https://iopscience.iop.org/article/10.1088/1748-9326/ab0fe3/meta?ref=blog.indecol.no). Designing and building buildings that last longer can reduce the use of concrete, steel, and glass. Individually owned cars are parked twenty-two or more hours a day. Shared fleets of vehicles offer mobility with fewer vehicles. Clever designs of buildings can save substantial amounts of structural steel. According to [our modeling](https://www.nature.com/articles/s41467-021-25300-4?ref=blog.indecol.no), such strategies can deliver up to a quarter of the potential emissions reductions from the passenger vehicle and housing sectors in the Global South. Energy and material efficiency offer avenues to reduce the total energy demand. Often, these kinds of efficiency strategies are readily available, require fewer capital outlays, and generate less conflict than renewable electricity or nuclear power. By reducing process-related emissions in material production, material efficiency offers emissions reductions that can’t be supplied through low-carbon energy alone. Our modeling clearly shows: if developing countries implement all three of these strategies, climate change mitigation doesn’t need to hamper the kind of development the Global South needs to bring a better quality of life to its citizens. ![](https://blog.indecol.no/content/images/2021/09/image-5.png) Annual GHG emissions from the making, use, and disposal of cars and homes in selected developing and emerging countries depending on whether material efficiency is implemented, and the energy system is decarbonized.

My name is Philip Gjedde, my double master’s programme in Residual Resource Engineering and Industrial Ecology on DTU (Denmark) and NTNU (Norway) have now led me to working in the Industrial Ecology programme in the Department of Energy and Process Engineering at NTNU as a PhD in the [ATLANTIS ](https://atlantis-erc.eu/?ref=blog.indecol.no)project. ![](https://blog.indecol.no/content/images/2021/09/image-3.png) Different species attached to a ship's hull (fouling) makes the ship a pathway to new ecosystems.

The importance of including a spatial context in the LCA framework then became evident to me and working with this challenge has motivated me further in developing tools for LCA and environmental assessments. A major gap in the LCA framework is the lack of modelling tools for marine impacts on a regional and global scale. ![](https://blog.indecol.no/content/images/2021/09/image.png) Barnacles on plastic litter.

My goal is to distinguish introduction pathways of invasive species in marine environments and quantify the impacts of invasive species on marine ecosystems – throughout “the seven seas”. I am thrilled, to say the least, about this challenge. I believe innovative thinking and collaboration with people of different skill sets will allow us to expand the already vast toolkit within the LCA framework to also include the last 70% of our planet's area: The ocean.

URL: https://blog.indecol.no/mammals-and-power-lines-a-problem/ Last updated: 2026-07-29T18:08:42.000Z We already know that [power lines can impact biodiversity, for instance birds](https://blog.indecol.no/birds-power-lines/). But – actually – most of our knowledge is based on birds! Other animal groups (or plants!) do not get as much attention \[1,2\]. But in this post, we’ll put a spotlight on mammals. ![](https://blog.indecol.no/content/images/2021/08/image.png) *Number of published papers about power lines’ impacts on various groups \[2\]* Similarly to birds, mammals can get electrocuted – for example when they touch two conductors simultaneously. But unlike birds, there is a lack of data about mammals as potential victims. Although electrocution is known to cause death for some bats species \[3\], bats are often overlooked when assessing the impacts of power lines \[1\]. Electrocution was observed in other mammals \[4\], but only a few individuals were reported. When building power lines corridors, you cannot escape the necessary removal of existing vegetation to make room for pylons. By “cutting” the landscape, you can end up affecting habitats \[5,6\] by: 1. Fragmenting it - instead of having one continuous habitat you end up with numerous small, isolated areas. 2. Changing it - the local plants are often replaced by invasive species \[7\]. 3. Losing it. But when we address mammals, do power lines actually pose a physical barrier for species? Well, yes! And also no. Mammalian species that dwell primarily in forests avoid narrow forest clearings, including power lines corridors \[7\]. Medium-sized mammals – mustelids or squirrels – prefer to remain in forests, and therefore tend to shun narrow forest clearings \[8\]. Predators, on the contrary, LOVE linear clearings. It makes life easier to walk within a path cleared from trees compared to a dense forest – especially when you go hunting \[8,9\]. An increased predation risk may explain why ungulates (e.g. caribou, deer or moose) try to avoid fragmented landscapes \[10\]. ![](https://blog.indecol.no/content/images/2021/08/wolf-2984865_1920.jpg) Wolves (*Canis lupus*) can walk faster and further within narrow forest clearing during summer \[9\] Or maybe it’s all about us? Human activity also takes its toll on animals. In some cases, species reduce their abundance near infrastructure \[11\]. Reindeers, for instance, prefer to use areas located far away from power lines and in some cases do not dare to cross them \[12\]. It is, however, possible that their movement is affected only during the construction phase. And that afterwards, they return to use areas near power lines \[13\]. Moose also did not seem to mind power lines much \[14\]. Maybe power line corridors are not necessarily that bad. They can also be an opportunity, as the availability of plants there is quite different compared to a forest. Moose and deer species were observed foraging under power lines \[6\]. Furthermore, one study showed that moose had no preference to either linear clearings or forests, and even increased its habitat use near linear clearings \[8\]. Small mammals seem to be unaffected by power lines corridor \[8\]. The total number of species there might even increase. That’s what a group of researchers discovered while examining a power line corridor, forest edge and forest habitats. Surprising? Not necessarily. Remember that species richness isn’t everything. The two rodent species that dominated that corridor did not belong in the forest. Moreover, the evenness of species (similar number of individuals per species vs. single dominant species) was the highest in the forest \[15\]. Increase in species richness can often be based on increase of generalist species (species that can live in multiple habitat types and consume different food resources). Specialist species (species that require certain food resources or specific habitat preferences), however, are much more vulnerable to environmental disturbances \[16\]. Changes in the landscape affect species differently and it’s important to consider that variation among species when assessing how they are impacted. ### References: \[1\] Richardson, M.

The conference serves as a contribution to Norway's role as a maritime nation, and every year they invite researchers, policy makers, innovators and citizens to get engaged in the topic of oceans. This year, the main question setting the scope for the conference is: > "How can NTNU, Trondheim, and Norway contribute to achieving the UN goals for sustainable oceans?" The conference is also digital this year, so in addition to the sessions with speakers and panelists, NTNU Oceans have created an online Research Gallery with short videos from Post-Doc, PhD and master students working with ocean related research at NTNU.

URL: https://blog.indecol.no/why-do-materials-matter-for-global-climate-action/ Last updated: 2026-07-16T21:38:24.000Z On 15-16 April 2021 the [**World Circular Economy Forum + Climate (WCEF)**](https://www.wcefplusclimate.com/?ref=blog.indecol.no) was held. The virtual summit was organized jointly by the Netherlands’ Ministry of Infrastructure and Water Management and Ministry of Foreign Affairs, and the Finnish Innovation Fund Sitra. The WCEF aimed to draw attention to the importance of a circular economy in reaching the climate goals. Professor [Edgar Hertwich](https://www.ntnu.edu/employees/edgar.hertwich?ref=blog.indecol.no) presented the results from the [**IRP report on Resource Efficiency & Climate Change**](https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change?ref=blog.indecol.no). This report examines the mitigation opportunities presented by higher material efficiency in the production and use of residential buildings and high-duty vehicles. ![](https://blog.indecol.no/content/images/2021/04/WCEF-session-2-slides.jpg) During the session, representatives of governments, businesses and research institutes introduced multiple ways in which the circular economy can reduce the carbon footprint throughout the value chain, and how these can be incorporated in policymaking. We sum up the discussion in 7 key messages: 1\. The Global Resources Outlook shows that the extraction and processing of the resources causes 50% of global climate change, and 80% of water stress and land-related global biodiversity loss. However, material efficiency has largely been overlooked in climate policy until now. ***Janez Potocnik*** 2\. The Resource Efficiency and Climate Change study identified the most promising opportunities to decrease emissions through material efficiency in the building and transport sectors. The most effective strategy is more intensive use by using less space and taking fewer individual rides. It implies important changes in the ways we live and move (shared cars, multi-family homes). ***Edgar Hertwich*** *3\.* Automobile industry is starting to look at the material efficiency strategies, including recycling, reparability, longer lifetime of vehicles, design, etc. We need to focus on things that can be done quick, such as, recover and reuse of materials from old vehicles and increase shared mobility. ***Anirban Ghosh*** *4\.* Implementing better regulations (i.e, waste regulation, taxation of activities) can incentives business to make improvements and it is great way to initiate performance changes. ***Andrew Spencer*** 5\. Policymakers need to be braver and use the tools they have (regulation, taxation, legislation, etc.). We also need international agreements to have the same kind of rules for everyone. ***HE Krista Mikkonen*** 6\. Sustainable lifestyle needs to be easier and cheaper. ***HE Krista Mikkonen*** 7\. Consumers need to have freedom and transparency to make their choices but, at the same time, governments need to set the market conditions. For instance, prices need to be correct and make sustainable choices affordable. ***Janez Potocnik and Edgar Hertwich*** You can watch the session again here! A well remembered kit can shape how supporters talk about a team because fans often compare the emotional pull of old and new designs. Collectors interested in Tottenham Hotspur often look at how different seasons changed the shape and details of the shirt. Among the options linked to club identity, [how to choose a Borussia Dortmund football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) is connected to the way fans compare eras, colours, and shirt details. The interest in classic kits keeps the paragraph grounded in football culture rather than simple promotion. ### So what’s the story with birds and power lines? URL: https://blog.indecol.no/birds-power-lines/ Last updated: 2026-07-29T18:08:44.000Z You’d think that birds, which often sit on power lines, wouldn’t mind them. However, power lines affect birds in several ways. Firstly, they act as an artificial barrier. Did you know that power lines kill millions of birds every year? \[1,2,3\]. In fact, scientists estimated that between 12-64 million birds die **annually** from collision and electrocution in the US alone \[4\]. **Collision** occurs when a bird flies into overhead wires. Some birds are more susceptible to collide than others, especially species with small wings yet relatively large bodies (rails, coots and cranes), because they are less capable of manoeuvring their flight. Also, birds that fly together in flocks (ducks, pigeons and starlings) can have limited sight and/or space to control their movement \[2,6\]. Other potential risky traits are being a night owl (literally!) or active during dawn or dusk, as visibility conditions during these times may be limited. Being a young inexperienced individual may also increase the chances of hitting a power line, as well as having certain flight behaviours, e.g., hunting, displaying courtship or defending territories, since they might take away all the focus while approaching a power line \[2,6\]. ![](https://blog.indecol.no/content/images/2021/04/800px-Kerro-_Coturnix_coturnix-1.jpg) ![](https://blog.indecol.no/content/images/2021/04/Otis_tarda_-cropped--1.jpg) ![](https://blog.indecol.no/content/images/2021/04/White_Stork_-Ciconia_ciconia--_Zajki_meadows-_Eastern_Poland-1.jpg) ![](https://blog.indecol.no/content/images/2021/04/675px-Pica_pica_-_Compans_Caffarelli_-_2012-03-16-2.jpg) ![](https://blog.indecol.no/content/images/2021/04/450px-Buteo_buteo_-Netherlands-8-1.jpg) ![](https://blog.indecol.no/content/images/2021/04/16309337267_f4d5c9658d_h-2.jpg) Three common **collision** victims (top images from left to right): Common Quail *Coturnix coturnix*, Great bustard *Otis tarda* and White Stork *Ciconia ciconia*; three common **electrocution** victims (bottom images from left to right): Magpie *Pica pica*, Common Buzzard *Buteo buteo* and Common kestrel *Falco tinnunculus* **Electrocution**, on the other hand, happens when a bird touches either two conductors or a conductor and a grounded component at the same time \[4,5\]. Electrocution mostly affects raptors that perch on the pylons and in some cases even nest there \[3,4,6\]. Size is a relevant factor, as larger birds have a higher chance to reach both conductors and a grounded device simultaneously. Among the most common victims are hawks, vultures, eagles, crows, falcons, owls and storks \[5,6\]. Although researchers assume that bird populations are overall not affected by collision and electrocution, most studies actually don't address effects within populations \[1,3,6\]. But for some endangered species, power lines pose a serious threat, e.g. the vulnerable Spanish Imperial eagle (*Aquila adalberti*) \[7\] or the endangered Saker falcon (*Falco cherrug*) \[8\]. Secondly, power lines also play a crucial role for birds when choosing where to nest or rest. Some species prefer sites that are well distanced from power lines, others might even abandon their territories if the density of power lines is high. It’s possible that birds acknowledge power lines as a barrier and therefore change their flight behaviour \[3\]. Furthermore, the construction of the pylons, which requires the removal of existing vegetation (often followed by a re-colonisation of invasive plants), can degrade the quality of the habitat and eventually lead to its loss \[3,5\]. I already mentioned that pylons are favoured by birds (mostly raptors and crows) as a good perching spot. The usage of power lines may in some cases increase species’ home range and population size. But on the other hand, it can alter the natural dynamic between predators and their prey and add more pressure on some bird populations. It’s no wonder then, why some birds prefer to avoid areas near power lines \[1,3\]. The impacts of power lines on birds have been (and still are!) studied for several decades, but some research gaps remain. For instance, understanding the impacts throughout the entire life of power lines (including construction and operation phases), considering multiple organism groups rather than focusing on certain species and developing a better impact quantification to address the effects on populations, communities and ecosystems \[1,3\]. **References:** \[1\] Richardson, M.

The workshop had almost 30 attendees and a very diverse speaker list from around the world. After a general introduction into the project, life cycle assessment and the current framework for including plastic waste into life cycle impact assessment by Francesca Verones and John Woods, very interesting topical presentations about the data needed and available for macroplastic impacts and the movement of plastic particles were held by a number of experts from South Africa, Norway, the US and New Zealand. The workshop showed that while a lot of inofrmation is available, there are still many gaps to be filled. Covergae of species that are entangled in pallstic waste is till scattered and incomplete. Also for the impact of invasive species that are rafting on marine debris, there are unknowns, such as how long they can survive on these rafts. Some manage to survive decades at sea! The workshop showed that the project is definitely needed to help cover sustainability aspects related to plastic waste and that a lot of research is still needed. Discussions about national team shirts can hold memories of tournaments, cities, and shared celebrations because shirts can show how clubs balance heritage and modern style. Classic sponsor layouts can change the way a shirt is valued by fans who follow design closely. For fans weighing fit, fabric, and team identity, [Benfica football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) is a natural way to describe interest in club apparel without sounding promotional. The focus on fit and fabric keeps the focus on clubs, supporters, and the stories behind each design. ### Five Indecol Professors featured in World’s top 2% scientist list URL: https://blog.indecol.no/five-indecol-professors-featured-in-worlds-top-2-scientist-list/ Last updated: 2026-07-29T18:08:47.000Z Standford University has recently released a list that identified the top 2 percent of the world’s nearly 7 million working scientist in various disciplines.

If you were being questioned, you may immediately think of Plastic. Yes, plastic is very widely used in our life and pollution due to plastic has been an emerging, global environmental problem in the past few decades. Among all the issues linked to plastic, ocean plastic debris is one of the most addressed issues and has gained more and more public attention worldwide. It is often asked where this plastic debris is coming from. It can be categorized into land-based (household, tourism, etc.) and sea-based plastic (shipping, fisheries, etc.), where the sea-based plastic counts for around 20% of total ocean plastic debris \[1, 2\]. The vast majority of sea-based plastic debris can be traced back to the industry of fisheries and aquaculture \[3\]. As a country well known for sea-food, Norway offers plenty of choices on the dining table such as salmon, herring, mussel, scallop and sea-urchin. These delicacies naturally triggered my curiosity about Norwegian fisheries and aquaculture’s role in ocean plastic debris. So, right after enjoying a decent seafood meal, I decided to dive into plastics issues in Norwegian fisheries and aquaculture. I wanted to figure out: (1) How does plastic deployed in fisheries and aquaculture turn into ocean plastic debris? (2) How large is the volume? (3) What happened to the rest of the plastics? At the end of my project thesis, an overview of Norwegian fisheries and aquaculture became clear: (1) How does plastic deployed in fisheries and aquaculture turn into ocean plastic debris? The facilities and tools used in fisheries and aquaculture require a lot of plastic, such as fishing nets, buoys, feeding pipes, etc. Due to weather, operation condition, and some accidents, they may get worn out, age and lost, and enter the ocean as debris eventually. (2) How large is the volume? Unfortunately, limited by the lack of existing systematic surveys, only a very rough estimate of the contribution to ocean plastic debris is available: 4800 t from fisheries and 1200 t from aquaculture, equal to 10% and 9% of their total annual plastic waste respectively. \[4,5,6,7\] (3) What happened to the rest of the plastics? As for the rest of the plastics, which is properly collected and managed, it is used for material recovery (recycling) or energy recovery (incineration), and the remainder is landfilled. Although the estimated results are approximate, the magnitude is still shocking. Moreover, this is what happened under the active promotion of ocean plastics retrieval from the Norwegian government and society. Imagine in other parts of the world where regulation and social collaboration are missing, the situation maybe even worse. Despite the severe challenges brought by ocean plastic debris, it is gratifying that more and more efforts are being invested into the research and control of ocean plastic debris, and cooperation in this field is more and more extensive. As a global problem, the solution to ocean plastic debris is inseparable from the interdisciplinary, interdepartmental, interregional, and intergovernmental joint efforts. Only in this way can we achieve the common goal for our human future: when we enjoy nature by the seaside, there will be no plastic eyesore floating on the sea, no need to worry about entangled sea turtles and birds, and no concern of microplastic-containing seafood. We can proudly tell the next generation: we have succeeded in cherishing and protecting our oceans——the cradle of all life. **References** \[1\]US EPA, O.

Supporter culture is shaped by chants, colours, badges, and the shirts worn on matchday because it links personal memory with the wider culture of the game. Modern ventilation panels can affect whether a shirt feels right for matchday wear or display. For supporters studying famous shirt designs, [La Liga football shirts](https://www.camisetatienda.com/?ref=blog.indecol.no) is a natural topic when the focus is on design, fit, and supporter meaning.

My name is Dafna Gilad and I just recently joined the [Industrial Ecology Programme](https://www.ntnu.edu/indecol/industrial-ecology-programme?ref=blog.indecol.no) in the Department of Energy and Process Engineering at NTNU. With background in ecology and conservation biology, the promotion of wildlife conservation has always been important to me: I participated in nature conservation and research projects, aiming to preserve and study bird species like the kākāpō, kiwi, kārearea and the red kite. Therefore, I acknowledge the urgency to develop effective impact evaluation frameworks to address and mitigate human activities on wildlife. That is where [life cycle assessment](https://www.sciencedirect.com/topics/earth-and-planetary-sciences/life-cycle-assessment?ref=blog.indecol.no) (LCA) kicks in. LCA is a holistic instrument that analyses the environmental impacts of a product or a system over its life cycle: from the extraction of raw materials, through production and usage, till its disposal. In the [CONSENSE ](https://www.sciencedirect.com/topics/earth-and-planetary-sciences/life-cycle-assessment?ref=blog.indecol.no)project, we will implement LCA to quantify the environmental impacts of energy systems – including renewable energy – to understand and minimise their effect on biodiversity. I am supervised by Francesca Verones (NTNU) and co-supervised by Roel May (NINA). My tasks within the project are to identify the impact pathways of power lines, assess the overall impact of the current electricity supply-demand and evaluate potential impacts of future electricity production in Norway. Supporters often connect a favourite team with the design worn during a memorable campaign as fans compare old designs with the look of newer campaigns. Home and away kit collections can change how a shirt feels for daily wear, display, or collection. Among the options linked to club identity, [football shirts for retro kit collectors](https://www.camisetatienda.com/?ref=blog.indecol.no) is a phrase that sits comfortably in content about football identity. The focus on fit and fabric helps explain why different versions can matter to different fans. ### The ocean plastic pollution from a Norwegian perspective URL: https://blog.indecol.no/the-ocean-plastic-pollution-from-a-norwegian-perspective/ Last updated: 2026-07-29T18:08:54.000Z There is no doubt that the increasing plastic pollution of the world's oceans has also reached Norway. Plastic bottles, fishing nets and countless other plastic items can now be found even on the most remote coastline stretches in the far north of Norway and are no longer only a problem of heavily frequented beaches in the south of the country. Unsurprisingly, also the number of scientific literature addressing microplastics found in fish, pictures of marine mammals entangled in plastic waste, and observed seabirds starving despite a full stomach is increasing. Initiatives such as the recently enacted EU regulation on single-use plastic try to counteract the pollution of the oceans whereas e.g. the [ATLANTIS](https://atlantis-erc.eu/?ref=blog.indecol.no) project seeks to account for the impacts of plastics on marine ecosystems to better understand the effects of mismanaged plastics. To invest the limited resources in research and sustainable mitigation measures in the best possible way, it is advisable to determine the current state of knowledge. This includes getting a greater picture of the extent of pollution as well as locating its source. Anyone who seeks to do so for the Norwegian case will quickly realise that no definitive statement can be made about the absolute amount of plastic pollution nor its concrete material composition. While global models and estimations exist, the Norwegian plastic pollution status has to be roughly estimated from beach clean-ups and documented losses from sea- and land-based waste sources. Especially the beach clean-ups indicate that waste from (industrial) fishing and aquaculture is mainly responsible for the increasing abundance of marine litter. According of a report published by Mepex in 2020, around 40% (weight-based) of the plastic found along the entire Norwegian coast could be attributed to the fishing industry, mostly consisting of ropes, trawls and other fishing gear. However, clear regional differences can be observed. While the relative share of plastic waste from the fishing industry rises with increasing latitude and accounts for almost 60% in the North of the country, plastic items from personal use dominate among the plastic items in the area around Oslo. A closer examination of found food packaging furthermore revealed that the vast majority of those that could be identified had their origin in Norway. Only 23% could be attributed to other countries, which gives valuable information regarding possible programmes to avoid littering or to mitigate possible shortcomings in the regional waste management systems in the future. The adverse effects of marine plastic litter are manifold. For example, the number of Northern fulmars found with plastic residues in their stomachs has reached a worrying level. In addition, marine mammals and even land animals grazing at the coast are affected by entanglement in mainly fishing gear. This gear, often lost or deliberately abandoned, also causes ghost fishing and thus poses a serious threat to biodiversity and fish stocks in Norway. Even though the list of encountered species affected by entanglement and ingestion is comparably lower than the well-investigated regions of the North-Western Atlantic or Northern Pacific, the number of affected species and individuals is likely to increase with further investigation. Moreover, there are other effects such as smothering of marine fauna and corals or the rafting of pollutants and alien species on plastic litter. Especially if rafting affects sensitive ecosystems, vulnerable equilibria can be disturbed and irreversible damage can occur. Even though no published observations of smothering or rafting in Norway can be found, it is unlikely that these do not take place in Norwegian waters too. In general, further research is needed to estimate the negative effects of ocean plastic waste, its long-term effects on fauna and flora as well as its socio-economic implications. But there is hope: a bunch of preventive and end-of-pipe solutions both of technical and non-technical nature are available. The great variety reaches from financial incentives, legal approaches, technical inventions to awareness raising initiatives.

To succeed in this fight, before it is too late, we need more data and new knowledge as a foundation for decisive actions by governments, companies, and individuals. SANO Excursion 1H2021 aims to contribute by facilitating young people working together across academic, social, geographic, cultural, and legislative boundaries. The program, “Interns for Sustainability”, is made possible by a generous grant from the Norwegian Retailers’ Environment Fund. This pilot project, running from January to June 2021, will bring together 40-50 young researchers (and their supervisors) from both countries. The participants will form small working groups, each focusing on a particular issue (to be decided by the group) related to plastic pollution. The idea is that sharing ideas, insights and knowledge across traditional boundaries will enrich and add value to the participants’ individual projects at their home institutions. The pilot project will kick-off in January 2021 by digitally connecting concurrent workshops at the Sustainable Seas Trust in Port Elizabeth, South Africa and at NTNU in Trondheim, Norway. We hope to be able to bring everybody together in person at the concluding workshop in Norway in June 2021, Covid-19 permitting. In the interim, the groups will work together on-line, augmented by weekly guest lectures and information sharing within the pilot project. Home, away, and third kits each tell a different part of a club story when a classic design returns through a retro collection or anniversary release. Number printing choices can change the way a shirt is valued by fans who follow design closely. When personalised names and numbers matter, [Bayern Munich football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) is connected to the way fans compare eras, colours, and shirt details. For collectors comparing older shirts, the link between design and identity remains clear. ### Two presentations from ATLANTIS team members URL: https://blog.indecol.no/two-presentations-from-atlantis-team-members/ Last updated: 2026-07-16T21:38:36.000Z In the beginning of November, Marthe had the opportunity to present her ongoing work with marine plastic debris entanglement through a seminar called Ocean talks. This series of seminars is hosted by the student organization NTNU Ocean Club at the Norwegian University of Science and Technology in Trondheim. The theme of the talk was “Waste in the ocean” and how our way of life impacts the ocean, making it a good match with the objective of ATLANTIS and Marthe’s research. Other topics presented during this Ocean Talks included the development of bioplastics from seaweed, utilizing jellyfish as a means to combat marine litter and dealing with lubricant waste in the oceans. As such, the topic of ocean waste was covered from the angle of the problems to innovative industry solutions, which made it a diverse and interesting seminar. Francesca had the chance to present the larger ATLANTIS project to the REVOcean Initiative. The aim of this presentation was to show what kind of data and models are being developed in the ATLANTIS project and how these could feed into the large planned Ocean Data Platform. At the same time we could discuss our needs for data for validating our models for when the REVOcean vessel will be operational and collecting data. A football shirt can turn a season, a badge, and a colour scheme into part of supporter identity when a tournament or league season gives the design a lasting meaning. Modern ventilation panels allow a paragraph to connect practical choice with football identity. For collectors looking at classic seasons, [football shirts with names and numbers](https://www.camisetatienda.com/?ref=blog.indecol.no) remains connected to the way fans compare eras, colours, and shirt details. A thoughtful shirt choice keeps the paragraph grounded in football culture rather than simple promotion. ### EXIOBASE update: v3.8 URL: https://blog.indecol.no/exiobase-update-v3-8/ Last updated: 2026-07-29T18:08:57.000Z We just released a new update for the EXIOBASE 3 MRIO time-series of monetary tables: v3.8. It is a full re-estimate of the time-series, but still relies heavily on "now-casting" economic structure (and environmental extensions). [![image](https://zenodo.org/badge/DOI/10.5281/zenodo.4277368.svg)](https://doi.org/10.5281/zenodo.4277368?ref=blog.indecol.no) For the SUT and IOT coefficient data the latest available source data is for 2011\. As such, the data is likely good for global analysis, and country level estimates, but the uncertainty relative to official data at transaction level would be considerably higher. The time-series extends into the future (2022), but this is based on the now-casting procedure and projections of GDP and aggregate trade of the IMF. Most of the updates were done by [Richard Wood](https://www.ntnu.edu/employees/richard.wood?ref=blog.indecol.no). # Main updates Macroeconomic and trade data for recent years - Updated to 2018 macroeconomic data from UN, and GDP & gross import/export projections until 2022 from IMF. - Trade data from Comtrade/BACI in HS6 classification (detailed data) updated to 2018 Energy and energy-related emissions - At detailed level, energy / emissions updated to 2015 IEA energy balances - At an aggregate level, all CO2 fossil emissions updated to 2019 based on Edgar Database; all other GHG emissions updated to 2017 based on PRIMAST database. More recent data are now-casts. - There is a major update to the historical time-series of non-fuel combustion GHG emissions. Non-fuel combustion GHG emissions are now scaled to match the PRIMAST dataset, with sectoral (IPCC based) emissions by gas availabe. Land, material and water-related data - No updates to v3.7, so purely reliant on now-casts post 2011, or 2013 in the case of materials. Co-efficients for environmentally-relevant flows - No updates to v3.7 Balancing algorithms - No updates to v3.7 As of v3.8, the end years are: 2015 energy, 2019 CO2, 2017 all GHG, 2013 material, 2011 most others, land, water. More recent data are purely "now-casts". # Public vs private version Note, that there is a public ([available on Zenodo](https://doi.org/10.5281/zenodo.4277368?ref=blog.indecol.no)) and private EXIOBASE datasets. The private dataset contains more detailed working files - we are not able to make these fully public because they contain licensed data for energy (IEA), land use and material flows (so these are aggregated in the public version). We don't have permission to release these files to users without requisite licences, and use of the data here should be undertaken only in respect to these licenses. Please contact us for access to the private version with providing evidence for the relevant licences. # Prior Release Info v37 (June 2019) - includes all notes relating to 36 below, but also updates to the emission accounts where the emission accounts are updated [as described Wood et al 2020](https://t.co/miLWSbqIXW?amp=1&ref=blog.indecol.no) - includes simplification of balancing from purchaser price to basic price for the reconciliation step (hence purchaser price data no longer part of balancing). Pricing layers are now available only in the "init" tables of the individual country SUT files. - includes a fix regarding data constraint on macro-economic data regarding taxes less subsidies on final demand. Fix regarding gap filling where binary discrepancy between EXIO2 data and EXIO3 trade data occurs v36 (September 2018) - includes new energy and emission accounts, energy and emission accounts updated for better consistency with MSUT, and updated to 2015. - includes net energy account broken down by type, and explicit identification of losses (new stressor classification). - includes more coefficient constraints (implemented in coeffixer, see coef\_fixer log file) - switch from QP to CE in objective of trade data reconciliation. v35 - update of the Macro-economic account (based on a problem identified in RoW ME) - inclusion of the net energy account - major update of land and water extensions - major update of coefficient constraints (in CoefFixer) The data here has different end-dates for the environmental extensions. Anything beyond the end date is an extrapolation. As of v3.5, the end year is: 2011 energy, 2015 CO2 fuel combustion, 2013 material, 2011 most others, incl methane and N20, land, water As of v3.6, the end year is: 2015 energy, 2015 CO2 fuel combustion, 2013 material, 2011 most others, incl methane and N20, land, water As of v3.7, the end year is: 2015 energy, 2016 all GHG, 2013 material, 2011 most others, land, water land extensions to 2015 are available on request soon, but not yet processed. Constant price data has been estimated, but we are not robust enough to be released yet. Price indices for each product in the database are available. # Bulk Download To allow the download of specific years we uploaded the data as zip archives per year and mrio type (industry by industry: ixi, and product by product: pxp).

And please also check our [main EXIOBASE 3 announcement blog post here.](https://environmentalfootprints.org/blog/exiobase3/?ref=blog.indecol.no) # Data quality/adherence In terms of data quality for more recent years please be mindful of: - 2007 is the base year for the SUTs and the method of interpolation over time involves using data in different classifications and formats to understand structural change over time (i.e. intermediate and final demand flows by product and industry). Only output, trade and macroeconomic constraints (7 sectors) are direct inputs to final balancing in absolute terms. The database is under the NACE1 classification scheme. - SUT and IOT data are only used to inform structural change - Whilst the 2007 EXIOBASE2 table is the base, the National Account Main Aggregates is the main constraint. The main goal was temporal consistency, and not disaggregation of official tables in EXIO3\. SUTs/IOTs do often not get updated going backwards, whilst National Account Main Aggregates data does. In general, National Account Main Aggregates are often 10-20% off the equivalent data points aggregated from the official SUTs/IOTs from 2007. Energy & emission accounts Energy and Emission accounts are based on the IEA energy balances, but are not always fully consistent with the monetary IO tables (different data sources was used in the disaggregation of the energy accounts). This does lead to some minor discrepancies in relationships between energy flows and monetary flows. Some efforts are ongoing to fix these. Household use of energy is available in disaggregated form (by EXIOBASE product), but is auxiliary to the main MRIO dataset, as it does not fit that data structure. Similar case for fuel combustion emissions. # Further Updates and Development In terms of financing future work, we of course are reliant on funding. We are updating parts of the dataset based on individual project requirements, and providing some internal funding for co-ordination across these efforts. We are of course welcome to participate in projects that help fund these updates, either central updates or peripheral work that has benefits for both a single end-user, but also that can be rolled into future public data releases. We are continually updating the data behind EXIOBASE with a rolling release cycle. Hence more feedback that is given, the greater the chance of improvements in future updates! # Announcements Stay tuned for announcements [by subscribing to our EXIOBASE email list.](https://groups.google.com/forum/?ref=blog.indecol.no#!forum/exiobase-announcements) Al considerar [camisetas de selecciones para coleccionar](https://www.camisetatienda.com/?ref=blog.indecol.no), la decisión resulta más sencilla cuando se confirma el tipo de tejido y el corte propio de la época.

In [a new report for the International Resource Panel](https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change?ref=blog.indecol.no), we show that reducing the use of emissions-intensive materials such as metals and cement in buildings and cars can lead to significant emission reductions. Savings are greatest with measures that reduce the need for new production altogether. Unfortunately, current policy often supports and promotes the use of more materials. It is natural to focus on energy use when we think of greenhouse gas emissions from buildings. In many countries, however, it is the production of building materials that is causing higher emissions than heating or cooling buildings. Scandinavia is a leader in the development of carbon-free material production with the Swedish [Hybrid](https://www.hybritdevelopment.com/first-pilot-plant-for-fossil-free-steel?ref=blog.indecol.no) pilot plant using hydrogen instead of carbon to reduce iron ore to iron and the [Norwegian carbon capture plans](https://ccsnorway.com/capture-norcem/?ref=blog.indecol.no) for cement production at [NorCem](https://www.norcem.no/en/CCS?ref=blog.indecol.no) in Brevik. It will take at least two to three decades for such advanced green technologies to transform material production, given that these have yet to be tested and commercialization remains. In the meantime, the focus should be on reduced use and increased reuse of emission-intensive materials. ![](https://blog.indecol.no/content/images/2020/11/image.png) In the resource panel report, we have quantified possible emission reductions through increased resource efficiency for housing and cars. We investigated policy instruments that affect resource efficiency. The results are clear. The largest emission reduction can be achieved through increased utilization of the products so that demand for new buildings and vehicles is reduced. Emission reductions are complementary to those achieved through energy efficiency and renewable energy. In relation to housing, we find that there is a significant potential for limiting the growth in floor space and improving the utilization of homes. For example, many older people continue to live in large homes when their children move out, while young people are desperately looking for a place to start their own family. Policies should make it easy to move to housing that is appropriate for the current life-stage, rather than hindering moving by increasing the cost of shifting ownership, such as through a tax on sales or a registration fee ([stamp duty](https://www.investopedia.com/terms/s/stampduty.asp?ref=blog.indecol.no)). **Small is beautiful …** Flats in multifamily buildings are smaller and often better organized than single-family homes. In addition, they tend to have lower energy consumption. Multifamily buildings also provide the opportunity to share part of the infrastructure. One example are shared guest rooms, which can be reserved if needed, rather than every flat having their own guest room. Unfortunately, in some countries such as the United States, tax breaks for home ownership are designed to favour single family homes. … **but large is more profitable** Failed policies are often co-responsible for large imbalances in the housing market, which lead to the over-consumption of housing by wealthy older people and a poor supply for younger and poorer population groups. Norway is a good example of that. Here, there are [large and unlimited tax incentives to invest in housing](https://www.skatteetaten.no/en/person/taxes/get-the-taxes-right/property-and-belongings/houses-property-and-plots-of-land/?ref=blog.indecol.no), such as tax deductions for mortgage interest and a tax exemption for the value appreciation in one's own home. Hence, for those who can afford it, it pays to buy a larger home even if they do not need it. The resulting rise in house prices makes it difficult for them young to save up enough equity to get into the housing market. The tax benefits could easily be limited to the first 30 square meters per person only, and a [land tax](https://www.economist.com/briefing/2018/08/09/the-time-may-be-right-for-land-value-taxes?ref=blog.indecol.no) could capture the windfall profit associated with rising property values. **Elegant, light structures** Several strategies can reduce greenhouse gas emissions associated with home construction. [Lighter constructions](https://block.arch.ethz.ch/brg/files/BLOCK%5F2020%5FStructural-Engineer%5FRedefining-structural-art%5F1578310555.pdf?ref=blog.indecol.no) such as trusses and self-supporting arches can reduce the amount of material per area significantly. Furthermore, [more material is often used than is technically necessary](https://www.uselessgroup.org/use-less/use-less-industries/construction?ref=blog.indecol.no), as research at [Cambridge](https://www.uselessgroup.org/?ref=blog.indecol.no) has shown quite unequivocally. We can use wood or other biological materials that bind carbon instead of reinforced concrete. But it is not only that there are few incentives to reduce the use of emission-intensive materials, many rules and standards practices favour high consumption of such materials. **Low-emissions materials** Eighty-five meters high [Mjøstårnet](https://www.dezeen.com/2019/03/19/mjostarne-worlds-tallest-timber-tower-voll-arkitekter-norway/?ref=blog.indecol.no) demonstrates that it is possible to build high-rise buildings from wood. Construction standards needed to be adapted to permit such a structure. The report recommends adapting regulations to promote environmentally friendly material choices and construction methods. Further, certification systems such as [BREEAM](https://www.breeam.com/?ref=blog.indecol.no) and [LEED](https://www.usgbc.org/leed?ref=blog.indecol.no) are important for buildings that are built better than what is required. Such systems should be adapted to promote material efficiency. Worldwide the greatest need to change construction practices is in China. China has surpassed England in floorspace per capita, while the rate of expansion continues to skyrocket. The building style is high-rise towers of glass and concrete, which need more material than the dense low-rise houses recommended in the Resource Panel’s [Weight of Cities](https://www.resourcepanel.org/reports/weight-cities?ref=blog.indecol.no) report. The service life of Chinese buildings has historically been extremely low, around 30 years. The hope is the quality of current construction has improved so that new buildings will be adequate for a much longer period. **Shared fleets of on average smaller vehicles** For cars, we find that strategies that reduce the number and size of cars can deliver significant reductions in emissions related to car production and operation. The sharing economy, which is based on mobile apps, can be the key to making better use of cars. On [ride-sharing](https://www.theguardian.com/sustainable-business/2017/apr/26/carpooling-commuting-car-share-liftshare-uber?ref=blog.indecol.no) platforms like [Same-Way](https://same-way.com/?ref=blog.indecol.no) or [BlaBlaCar](https://www.blablacar.com/?ref=blog.indecol.no), it is possible to find passengers travelling long distances or get hitch-hike with somebody. Acquaintances living in Denmark report that there is extensive use of ride sharing also for daily journeys with established 'stops'. It even starts competing with the bus. Perhaps a little safer in relation to infection control is car sharing, which has now also reached smaller cities, and which makes it easier to live without owning a car. You rent the car per hour when you really need it. The advantage of car sharing is that the size of cars in the car fleet decreases because you have a large car available the few times you need to shop for furniture, while you rent a small car if you are going to drive the child to the football match. Using on average smaller cars provides savings of both metal and energy. ![](https://blog.indecol.no/content/images/2020/11/image-1.png) Now that a transition to clean energy is underway, it is important to address the remaining sources of emissions. It is time for climate policy to aim at the significant potential to reduce emissions through material efficiency and the circular economy.

The aim of this project is to help prioritize solutions towards marine plastic pollution. For this reason the project aims to find out which polymer types, products and pathways are the most abundant ones. This is done on a country basis, based on national data and, if available, data from the industry producing, using and recycling plastics within the country. After these “hotspots” of plastic products and pathways have been identified, individual country interventions can be planned together with relevant stakeholders. The project released a report explaining the methodology behind the national guidance. It is exciting to see that methods like this one are proposed. There is no doubt that assessments like this, on national level, will have to deal with uncertainties and are crucially depending on the availability of data and the willingness of different industries and governments to share data. Still, this guidance provides an opportunity to assess the amounts of plastic that are potentially putting the marine ecosystems at risk and allow for the concrete planning of interventions. This is crucial, in order to minimize the amount of plastic reaching the oceans. [Project website](https://www.lifecycleinitiative.org/national-guidance-for-marine-plastic-hotspotting-and-shaping-actions/?ref=blog.indecol.no) [The national guidance report](https://plastichotspotting.lifecycleinitiative.org/wp-content/uploads/2020/07/National-Guidance-for-Plastic-Hotspotting-and-Shaping-Action-Final-Version-2.pdf?ref=blog.indecol.no) The choice between modern and retro shirts often reveals what fans value most when collectors use kit details to place a team in a particular period.

Owing to this, I am very excited to be a part of ATLANTIS! Within this project, I will be working on developing life cycle impact assessment (LCIA) models to quantify the impacts of plastic debris on marine ecosystems. This is an urgent need in environmental assessments in general and in the LCA framework in particular, as the potential for adverse effects of mismanaged plastic is currently left unaccounted for, due to the lack of a comprehensive methodology.

Going further with this research and developing an operational effect factor (EF) for this impact pathway is the first goal of my research as a PhD student. ### LC-IMPACT: a new spatially differentiated life cycle impact assessment method URL: https://blog.indecol.no/lc-impact-a-new-spatially-differentiated-life-cycle-impact-assessment-method/ Last updated: 2026-07-16T21:38:45.000Z [LC-IMPACT](https://lc-impact.eu/?ref=blog.indecol.no) was originally a project financed by the seventh framework program of the European Union. During the project many new models and approaches for assessing impacts on ecosystems and human health within a life cycle assessment framework were developed. However, an overarching combination of all these developments was lacking. This is what some of the researchers aimed to do after the end of the project and we have spent the last years to try and make the different models as compatible as possible. At the same time, we aimed for including spatially explicit characterization factors wherever possible and relevant. Today we proudly present the framework publication of this endeavor. You can find the open source publication[ here](https://doi.org/10.1111/jiec.13018?ref=blog.indecol.no). The report and the characterization factors can be downloaded [here](https://lc-impact.eu/?ref=blog.indecol.no). The marine ecosystem is, however, still underrepresented in LC-IMPACT and we hope that we can contribute with our work in the ATLANTIS project to change this.

Due to the situation with the Coronavirus, the conference could of course not be held as planned. Instead of canceling the conference, the organizers decided to transform the conference into a fully virtual meeting, complete with keynote speakers, scientific sessions, poster sessions and exhibition hall. Together with my colleagues from the [Marilca](https://marilca.org/?ref=blog.indecol.no) working group, I had a talk about the planned framework for marine plastic impacts within a life cycle impact assessment (LCIA) context. This framework is very important for making sure we have a holistic picture of the complex issues of marine plastics and I was delighted to be able to present a current version of it (see presentation section for the recording)! The virtual meeting was in my opinion very well organized, all talks were available on demand and questions could be asked and answered via a chat box. Instead of a regular session, there was a webinar which invited for discussion among the participants. I found that a very interesting format, because it allowed participants to watch presentations whenever they could (and now they also did not need to choose between sessions running at the same time) and the webinar allowed for a more overarching discussion than simple question-answer sets for individual talks. In this whole digital adventure the social, face-to-face component was of course missing, but for me the conference was nevertheless a big success and if such a virtual meeting could perhaps be combined with an on-site conference in the future, this could potentially be a way forward to reducing at least some of the business travel around the world. A shirt from a famous season can become a shortcut to remembering goals and rivalries especially when supporters associate it with a title race or a European night.

The papers describing the work in EXIOBASE 3 are coming out at Journal of Industrial Ecology ([https://onlinelibrary.wiley.com/journal/15309290)](\"https://onlinelibrary.wiley.com/journal/15309290%29\") in June 2018\. The database is available on [www.exiobase.eu](\"http://www.exiobase.eu/\") The data has aggregated energy and material accounts because of licensing issues with the IEA. See [environmental footprint](\"https://environmentalfootprints.org/footprints-embodied-in-trade/\") results. **Documentation** The main data documentation is described here [http://onlinelibrary.wiley.com/doi/10.1111/jiec.12715/full](\"http://onlinelibrary.wiley.com/doi/10.1111/jiec.12715/full\") This corresponds to version 3.4 of the data for the time series 1995-2011. **Versions** There was an earlier release of the data for v3.3 – for some uses, e.g. energy, emissions and material accounting, the data is valid. However, care should be taken in the water and land use accounts. There were major differences that were corrected in v3.4, and a public release of data for v3.3 will not be made available. Depending on research questions, the data may be impacted. **End-year** We also have estimates based on trade and macro-economic data up to 2016 as well, however, a lot of care must be taken in use of this data. It is not suitable for analyzing trends over time. The basic description of the process employed is in the relevant deliverable: [http://fp7desire.eu/documents/category/3-public-deliverables?download=24:d5-3-integrated-report-on-ee-io-related-macro-resource-indicator-time-series](\"http://fp7desire.eu/documents/category/3-public-deliverables?download=24:d5-3-integrated-report-on-ee-io-related-macro-resource-indicator-time-series\") The data here has different end-dates for the environmental extensions (2011 energy, 2015 CO2 fuel combustion, 2013 material, 2011 most others, incl methane and N20, land, water), and is not part of the main public release. Some work is going on to update these, but other collaborative efforts are more than welcome. **Data quality/adherence** In terms of data quality for more recent years. Please be mindful of: \-2007 is the base year for the SUTs and the method of interpolation over time involves using data in different classifications and formats to understand structural change over time (i.e. intermediate and final demand flows by product and industry). Only output, trade and macroeconomic constraints (7 sectors) are direct inputs to final balancing in absolute terms. The database is under the NACE1 classification scheme. \-SUT and IOT data are only used to inform structural change \-Whilst the 2007 EXIOBASE2 table is the base, the National Account Main Aggregates is the main constraint. The main goal was temporal consistency, and not disaggregation of official tables in EXIO3\. SUTs/IOTs do often not get updated going backwards, whilst National Account Main Aggregates data does. In general, National Account Main Aggregates are often 10-20% off the equivalent data points aggregated from the official SUTs/IOTs from 2007. **Updates** More specific updates for each environmental extension will be provided in relevant publications. Right now, our focus is on having a robust time-series to 2016\. We are not currently working on updating data past 2016, although we do expect to continue the work in the future. The data past 2011 is currently being made available through Box. Unfortunately, the only method of access is manual addition to the shared folder – please email Konstantin or Richard. Also ensure that you have read the limitations above and have registered on exiobase.eu In terms of financing future work, we of course are reliant on funding. We are updating parts of the dataset based on individual project requirements, and providing some internal funding for co-ordination across these efforts. We are of course welcome to participate in projects that help fund these updates – either central updates or peripheral work that has benefits for both a single end-user, but also that can be rolled into future public data releases. We are continually updating the data behind EXIOBASE with a rolling release cycle. Hence more feedback that is given, the greater the chance of improvements in future updates! **Announcements** Stay tuned for announcements: [https://groups.google.com/forum/#!forum/exiobase-announcements](\"https://groups.google.com/forum/#!forum/exiobase-announcements\") **Energy & emission accounts** Energy and Emission accounts are based on the IEA energy balances, but are not always fully consistent with the monetary IO tables (different data sources was used in the disaggregation of the energy accounts) – this does lead to some minor discrepancies in relationships between energy flows and monetary flows. Some efforts are ongoing to fix these. Household use of energy – this is available in disaggregated form (by EXIOBASE product), but is auxiliary to the main MRIO dataset, as it does not fit that data structure. Similar case for fuel combustion emissions. **Concordances** For useful concordances, please see: [https://ntnu.box.com/s/ziox4zmkgt3cdsg549brr0qaecskgjsd](\"https://ntnu.box.com/s/ziox4zmkgt3cdsg549brr0qaecskgjsd\") EXIOBASE3 is based on EXIOBASE2\.

This finding emerges from [a special report of the Intergovernmental Panel on Climate Change (IPCC) on 1.5 degrees](http://www.ipcc.ch/report/sr15/?ref=blog.indecol.no) released on Monday 8 October 2018\.

Technology is a key ingredient that offers us many possibilities; however, naïve faith in technology has also lulled us into complacency and blinded us to the social, political, and economic actions we need to take if we want to kick our carbon habit.

Climate policy has focused on technological development and promotion of cleaner alternatives. We have achieved initial success in the deployment of solar and wind power and electric vehicles, but at the same time allowed energy use to grow. We cannot achieve zero carbon emissions by building new runways and high ways, by continuing urban sprawl and economic growth by the ever-growing consumption of cheap, throw-away junk. We need entirely new models of economic development, social and individual well-being that are fundamentally different from the ones we have pursued in the 20th We must rid ourselves off our dependency on cheap, abundant fuels. [Grass-roots groups](https://www.sciencedirect.com/science/article/pii/S0959378018301109?ref=blog.indecol.no), urbanists, scientists, engineers, have taken promising initiatives to limit our footprint on this planet, and we cannot allow these to remain a side-show. - While we increasingly observe the consequences of climate change in rising temperatures, sea levels, and severity of storms, floods, and droughts, climate change remains a phenomenon that is primarily understood through science. Scientists observe and model solar radiation, atmosphere, oceans, the biosphere; they observe and quantify the impacts; and they model energy transformations and response strategies. The dominance of scientists in the public debate coincides with a weakness of social movements devising climate solutions and experimenting with the social, political, and economic change that scientists increasingly agree is essential for halting carbon emissions. I do not know whether this weakness of social movements is a consequence of the technical arguments that dominate climate policy debates and disempowers the common citizen, but it prevents the emergence of a politics of climate solutions. Even advocacy groups and think-tanks present themselves as quasi-scientific outfits and aim to gain influence based on the technical and economic merit of their proposals rather than building a ground-swell of support for those solutions. ![](https://blog.indecol.no/content/images/2020/06/image-1.png) Marching for the Climate. Photo credit: [Mark Dixon, Flickr](https://flickr.com/photos/9602574@N02/33551770633?ref=blog.indecol.no). - Possibly because of this lack of a ground-swell of political support for climate action, our governments have been unable to mount the scale of response required. This scale is comparable to the [response of governments](https://www.forbes.com/sites/mikecollins/2015/07/14/the-big-bank-bailout/?ref=blog.indecol.no) to the global 2007/08 financial crisis, the response of the US government to the 9/11 terror attacks, or the Chinese government’s one-belt one-road initiative. While the scale is not unprecedented or insurmountable, the speed is slower, the impact less immediate, and a longer-term commitment is required. The threat is not quite as imminent and visible as the collapse of the world trade towers or Bear-Stearns. Several world leaders have shown dedication to the climate cause and have managed to move the needle appreciably, but their actions have often been undone by a shift of priorities or [by vicious campaigns of fossil-fuel interests](https://doi.org/10.1073/pnas.1509433112?ref=blog.indecol.no). The weakening of government through globalization, of public debate through social media, of civil society through fragmentation, strife, and the conscious sowing of discord by moneyed and hostile interests, the world’s march on the [road to unfreedom](https://www.nytimes.com/2018/05/09/books/review/road-to-unfreedom-timothy-snyder.html?ref=blog.indecol.no), have seriously compromised our ability to mobilize the resources required. We will need to reconstitute our civil societies and political institutions to withstand the rougher conditions of the 21st century, not only to reduce emissions but also to protect ourselves from disease, tyrants, and the destructive consequences of global warming. When I started my scientific career in the 1990s, one could still make the argument that we did not fully understand the climate consequences of choices we needed to make, that low-carbon technologies were not mature and required further development, that better science and engineering was required. Today, we exactly know what to do, as the 1.5°report reiterates, but our actions remain inadequate. It is time to change that. ### Metals use tied to economic upswings URL: https://blog.indecol.no/will-more-expensive-metals-impede-economic-growth-in-the-us/ Last updated: 2026-07-16T21:38:50.000Z **Will more expensive metals impede economic growth in the US?** As the US government justifies new tariffs on steel and aluminum imports with their military importance, the role of metals in society comes into focus. [New research shows that metals are an important ingredient in economic upswings](https://t.co/Gu4R7yTvwF?ref=blog.indecol.no). Conversely, metal use declines rapidly in recessions. Restricting the access to metals or increasing their price may come at a cost to the economy. Metals are key enablers of economic development and human progress, being widely used for their superior structural properties, durability, and increasingly for their special chemical properties that are the basis for technological wizardry from drones to brain imaging. Access to metals is important for a modern economy. Taxing an important input to production may cause disruption in global supply chains. New research published in Nature Geoscience by a team of scientists from Yale, Tsinghua University, and NTNU tried to unravel the relationship between metal use and economic activity. ![](http://carbonfootprintofnations.com/wp-content/uploads/2018/05/MetalDemandGrowth-2.png) This research addresses the metal footprint, which is a way to combine the consumption of different metals to a single indicator. It represents the ore that needs to be extracted to satisfy the consumption in a country, even if the metal is actually employed in another country, as in the factory producing your laptop. The metal footprint reflects the effort in the extraction of the ore and represents the associated environmental costs. Since 1970, global metal ore extraction increased more than threefold, to 1.2 tons per person in 2013\. More than half of the metal footprint was caused by the large emerging economies: Brazil, Russia, India, China and South Africa (BRICS). The most significant growth was associated with iron ore, which expanded especially after the year 2000\. To understand this growth of metal use, one needs to understand what metals are used for. In 2013, two thirds of metal use was associated with investments, up from half two decades earlier. These macro-level descriptions, while interesting, tell us little about causality. That is why we conducted a panel analysis of metal footprint of 43 large economies looking at the time span of 1995 to 2013, for which good data was available. *We find that metal footprints are more strongly dependent on economic growth than any other resource or environmental indicator previously investigated.* *Increasing economic growth by 1% increased the metal footprint by 1.9%.* ![](http://carbonfootprintofnations.com/wp-content/uploads/2018/05/MF_GDP.png) We then went on to unpack this elastic, aggregated metal footprint-economy relationship. We tested the metal footprint effects of other factors, such as the degree of urbanization, the share of industry in value added, the share of investment in GDP, population density, or domestic ore extraction reflecting the availability of metals. Only investment proved to be important, and very important at that! We found that at the same level of economic growth, a 1 percent higher share of investment in GDP would increase the metal footprint of a country by 2 percent. With investment included, the sensitivity of metal use to economic growth became less, indistinguishable from a 1:1 relationship. We conclude that metal use is tightly coupled to economic development and to investment in particular. The finding raises questions about the impact of the Trump tariff on steel and aluminum. What will the impact of higher prices and reduced access be on the American economy? There are many ways by which a reduced access to metals can constrain economic growth. Many investment goods – cars, machinery, and buildings – are made from metals. As metals become more expensive, products made domestically from metals become more expensive and import of those products becomes more attractive. Increasing investment costs may reduce the level of investment and hence the capacity to produce goods in the future. The largest impact, however, will be in the construction sector, where shifting to imports is not really an alternative and higher costs are most acutely felt.

How can we ensure that technologies we employ to reduce greenhouse gas emissions do not give rise to the next generation of problems? Protecting the climate demands a fundamental reorganization of some aspects of our economy. How can we make sure that we select and develop solutions that offer us the largest net benefit? The [International Resource Panel](http://www.resourcepanel.org/?ref=blog.indecol.no) has now released the [second](http://www.resourcepanel.org/reports/green-technology-choices?ref=blog.indecol.no) in a series of reports investigating potential environmental trade-offs and co-benefits of green technologies. This report addresses energy efficiency, while [the first report addressed renewable energy and CO2 capture and storage](http://www.resourcepanel.org/reports/green-energy-choices-benefits-risks-and-trade-offs-low-carbon-technologies-electricity?ref=blog.indecol.no). The report provides strong support for energy efficiency strategies: they are very effective in addressing a wide range of pollutants, as well as land and water use. It offers the most detailed look at the potential side-effects of efficiency to date. Research teams studied individual technologies, such as [LED lighting](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12342/full?ref=blog.indecol.no), [building energy management systems](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12378/full?ref=blog.indecol.no), and efficient [copper smelting](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12369/full?ref=blog.indecol.no), in order to get an understanding of the resource requirements of manufacturing, use and disposal of efficient devices and their performance relative to conventional technologies. Going beyond individual technologies, implementation of new technologies was modeled in the context of their entire market and value chain. The approach is maybe most neatly illustrated by the work on transportation systems for [goods](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12277/full?ref=blog.indecol.no) and [people](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12391/full?ref=blog.indecol.no), conducted by colleagues in California and Arizona. For example, the study on [goods transport](http://onlinelibrary.wiley.com/doi/10.1111/jiec.12277/full?ref=blog.indecol.no) considers the shift of transportation mode – from land to rail to road – that is typical for many movements. For personal transport, it considered improvements in competing technologies as well as in the underlying electricity system which becomes more important as e-mobility advances. Research results on different technologies were integrated in a [life-cycle model of the global economy](http://pubs.acs.org/doi/10.1021/acs.est.5b01558?ref=blog.indecol.no), built specific for the purpose and specified to reflect the changes in [the electricity mix](http://www.pnas.org/content/112/20/6277?ref=blog.indecol.no) and the economy that come with the realization of the [2-degree and 6-degree scenarios](http://www.iea.org/publications/scenariosandprojections/?ref=blog.indecol.no) of the International Energy Agency. The model captured the interaction of implementing a whole portfolio of clean technologies in the 2-degree scenario. It compared those with the utilization of conventional technologies in the 6-degree scenario. Through the clean-energy scenario, 17 million tons of particulate matter per year can be avoided, saving many lives. Water use can be reduced by 200 billion cubic meters, land use by 150’000 km2. Individual technologies contribute substantially. For example, building insulation would reduce life cycle greenhouse gas emissions by 30-50%. Echoing findings of the earlier report, the new technologies would require more metals. Both PV and LED technologies rely on a wide range of specialty metals, while railways rely on steel. The new report offers little indication whether this increased metal demand poses a problem or not. An important issue that will be on the agenda for the International Resource Panel and other sustainability research. Our [previous study](http://www.pnas.org/content/112/20/6277?ref=blog.indecol.no), just of the electricity sector, showed that the additional metal demand for just electricity generation was modest, though, with potential concerns only related to the use of copper. ![](http://carbonfootprintofnations.com/wp-content/uploads/2017/06/GreenTechChoices_irp.png) *More information on the individual technologies can be found in a* [*special issue of the Journal of Industrial Ecology*](http://onlinelibrary.wiley.com/doi/10.1111/jiec.2016.20.issue-2/issuetoc?ref=blog.indecol.no)*.* Una comparación útil de [camisetas de fútbol para aficionados](https://www.camisetatienda.com/?ref=blog.indecol.no) comienza por el ajuste previsto para actividad deportiva o uso casual.

It is clear, this decision unmistakably indicates that the United States is no longer deserving of the global leadership role that it has long held but now sees as a burden. As other countries and parties way their options, they should not overlook a potentially powerful strategy to reduce the US carbon footprint: shift away from the dollar. This option is grounded in seemingly unrelated phenomena: First, in addition to driving oversized vehicles and having grossly inefficient buildings, a significant part of the carbon footprint of the United States is related its import of goods from other countries. The US has been running substantial [trade deficits](https://blog.bea.gov/category/trade-deficit/?ref=blog.indecol.no) with the rest of the world for well over two decades. *In 2016, the deficit in the trade of goods and services was $ 500 billion, or 3% of GDP. Measured in carbon, the US trade deficit amounted to 300 million tons of CO2 or 6% of its domestic emissions.* Nixing this trade deficit would be a useful contribution to global emission reductions, able to offset a substantial portion of the damage done by Trump. *Second, countries can run a persistent trade deficit and current account deficit only when somebody loans them money or invests in them. The US has been spending more than it earns for an extensive period of time, binging on consumption. Such an imbalance is normally not possible. It can only be sustained because* Third,US dollar serves as the global reserve currency. *Central banks of all countries need to hold dollars to stabilize their own currencies.* [As emerging economies develop, more dollars are needed](http://www.economist.com/news/finance-and-economics/21716618-pillar-global-financial-stability-under-threat-donald-trump-and-dollar?ref=blog.indecol.no), both to conduct international trade, as bilateral contracts, say between Saudi Arabia and South Korea, are denominated in dollars, and to grow foreign reserves of central banks. Other countries obtain the dollars they need by selling products to America. These sales are the root cause of the trade imbalances. The reserve currency system has become outmoded and a [threat to economic stability](http://www.economist.com/news/leaders/21669875-americas-economic-supremacy-fades-primacy-dollar-looks-unsustainable-dominant-and?ref=blog.indecol.no), especially given erratic US politics. It has become a bad deal for everybody. For those of us who invest in the US, [we get much lower returns on our investment than US companies accrue on their overseas investments](http://www.economist.com/news/finance-and-economics/21709549-exorbitant-privilege-looks-greater-ever-net-debt-big-returns?ref=blog.indecol.no). For US workers, a dollar overvalued compared to the economic vitality of the economy and subsequent competition from cheap imports has meant job losses and salary cuts. [Only US lawyers and banks benefit](http://www.economist.com/news/international/21601858-american-and-english-law-and-lawyers-have-stranglehold-cross-border-business-may?ref=blog.indecol.no). So, what can other countries do? First, get your central banks to diversify their portfolio of reserves to include a broader basket of currencies. Such a step is necessary in the long run, so better do it sooner! Second, start developing contracts denominated in other currencies or basket of currencies such as ‘special drawing rights.’ This step is also likely to reduce the exposure of these contracts to currency fluctuations. Third, get your own assets, including your pension fund, to shift away from investments in the United States, especially those in low-yield government bonds. You deserve better! These steps should relieve the US of the ‘exorbitant privilege’ of issuing the reserve currency of the world, thereby removing the reason for its trade imbalance. If we are collectively successful in our efforts, US consumers will reduce their emissions by as much as current emissions of global aviation. A worthwhile goal, no doubt. We will also have helped Trump achieve one of his election promises.

But are they really better than fossil fuels and nuclear power? ![The Conversation](https://counter.theconversation.edu.au/content/52484/count.gif?distributor=republish-lightbox-basic) To answer that question, one needs to compare not just the emissions of different power sources but also the [health benefits and the threats to ecosystems](https://doi.org/10.1088/1748-9326/aa6047?ref=blog.indecol.no) of [green energy](http://www.resourcepanel.org/reports/green-energy-choices-benefits-risks-and-trade-offs-low-carbon-technologies-electricity?ref=blog.indecol.no). Production of electricity is responsible for about [a quarter](https://www.epa.gov/ghgemissions/global-greenhouse-gas-emissions-data?ref=blog.indecol.no) of global greenhouse gas emissions, and demand is poised to rise as [underserved populations connect to the grid](http://iopscience.iop.org/article/10.1088/1748-9326/8/2/024015?ref=blog.indecol.no), and electronics and [electric vehicles](http://www.conservationmagazine.org/2016/09/evs-will-green-despite-increasing-power-demand/?ref=blog.indecol.no) proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, such as disrupting ecosystems and wildlife or causing [air pollution](https://www.nytimes.com/2017/02/14/world/asia/indias-air-pollution-rivals-china-as-worlds-deadliest.html?ref=world). In a [research paper](http://dx.doi.org/10.1088/1748-9326/aa6047?ref=blog.indecol.no), we analyzed the impact of electricity generation from renewable sources, [nuclear fission](https://en.wikipedia.org/wiki/Nuclear%5Fpower?ref=blog.indecol.no) power plants and fossil fuels, with and without [CO₂ capture and storage](https://en.wikipedia.org/wiki/Carbon%5Fcapture%5Fand%5Fstorage?ref=blog.indecol.no) (CCS) technology for separating CO₂ and storing it underground. We accounted for the environmental effects associated with the production, operation and dismantling of facilities, as well as the production, transport and combustion of fuels. We then compared a baseline scenario to a [low-carbon electricity scenario](http://www.iea.org/publications/scenariosandprojections/?ref=blog.indecol.no) that would prevent global average temperatures from rising more than two degrees Celsius above preindustrial levels by 2050 – the [point](http://newsroom.unfccc.int/unfccc-newsroom/under-2-mou-a-subnational-global-climate-leadership/?ref=blog.indecol.no) climate scientists say will avoid dangerous climate change. Our study emphatically confirms that fossil fuels – mainly coal – [place a heavy burden on the environment](https://theconversation.com/why-coal-fired-power-stations-need-to-shut-on-health-grounds-68809?ref=blog.indecol.no) and that most renewable power projects have lower pollution-related impacts on ecosystems and human health. Nonetheless, no energy source is without adverse environmental side effects. Power plant siting, project design and technology choice are critical issues that investors and governments should consider very carefully. ## Solar shines Replacing fossil fuel power plants with renewable energy sources, including solar, wind, hydropower and geothermal power, would reduce diverse types of pollution. The magnitude of difference in pollution between fossil and some renewable energy options is stunning. For example, we found that the entire process of manufacturing, setting up and operating photovoltaic panels causes less pollution than only delivering fuel to a coal-fired power plant when mining is included. What about the environmental footprint of actually making renewable energy systems? Photovoltaics (PV) comes out very well in our analysis. Today, the production of PV cells uses much less energy than previously. The carbon emissions per unit of PV electricity is one-tenth or less of even the most efficient natural gas power plants. Human health problems, such as respiratory disease from particulate matter exposure, are around one-tenth of those of modern coal-fired power plants with advanced pollution control equipment. Similar conclusions hold for water and soil pollution on ecosystems, we found. But solar panels require much more space to generate the same amount of power as fossil fuel or nuclear power generators. Shouldn’t covering huge areas with solar panels be a problem? Not necessarily. The amount of land needed to generate a kilowatt-hour from PV is comparable to that of coal power, when the land associated with mining coal is accounted for. And about half of the PV installations in our future scenario in 2050 could be placed on rooftops. Producing PV panels does require various metals, many of which are produced only in [limited locations](http://e360.yale.edu/features/a%5Fscarcity%5Fof%5Frare%5Fmetals%5Fis%5Fhindering%5Fgreen%5Ftechnologies?ref=blog.indecol.no). Some of those metals are highly toxic. Waste treatment and recycling, which we did not include in our assessment, are therefore important. PV, of course, delivers electricity only when the sun shines. However, a different solar technology – [concentrating solar-thermal power](http://www.eia.gov/energyexplained/?page=solar%5Fthermal%5Fpower%5Fplants&ref=blog.indecol.no), which concentrates light to make heat – may be a viable way forward as it delivers a similar performance in terms of pollution reduction yet offers the option to store heat and thus generate electricity in the evening. We assumed CSP technology, which currently has very low adoption compared to PV, would provide one quarter of solar electricity in our low-emissions scenario. ![](https://cdn.theconversation.com/files/161681/width754/image-20170320-9117-tb0cg.jpg) From the perspective of carbon emissions and health, solar power is far better than fossil fuel power generation. But large-scale solar plants require large tracts of land and can have a negative impact on local species.

[Some dams cause significant climate impacts](https://www.washingtonpost.com/news/energy-environment/wp/2016/09/28/scientists-just-found-yet-another-way-that-humans-are-creating-greenhouse-gases/?utm%5Fterm=.80b2d0eb8462&ref=blog.indecol.no) through the emissions of methane from the decomposition of biomass in reservoirs. Other dams [cause equally serious ecological problems](http://theconversation.com/chinese-hydropower-electrifies-southeast-asia-but-at-a-cost-20275?ref=blog.indecol.no) through habitat destruction. They can also block the migration of aquatic species and reduce sediment flow and nutrient transport, which affects floodplains and deltas. On the other hand, reservoirs form new habitats for birds and other species. Hydropower offers a good illustration of the importance of site selection and project design. Some projects may be economically viable but ultimately should not be realized if society considers the environmental degradation they can cause. For other projects, the impacts can be limited by mitigation strategies such as [environmental stream flow](https://en.wikipedia.org/wiki/Environmental%5Fflow?ref=blog.indecol.no) and [fish ladders](http://adventure.howstuffworks.com/outdoor-activities/fishing/fish-conservation/fish-populations/fish-ladder.htm?ref=blog.indecol.no), which provide a detour for migrating fish around a dam. Similar lessons hold for wind power, where habitat destruction during construction should be minimized and operations adjusted in order to reduce [collisions with raptors and bats](http://theconversation.com/what-can-be-done-to-make-sure-that-wind-energy-and-africas-vultures-co-exist-43677?ref=blog.indecol.no). Also, wind power resources vary widely across locations, which argues for choosing locations where wind resources are more abundant. ## Bioenergy threatens biodiversity [Biomass](https://theconversation.com/does-bioenergy-have-a-green-energy-future-in-the-us-46921?ref=blog.indecol.no) energy, or burning plant material for power generation, plays a central role in most plans to limit global warming to 2°C above preindustrial levels. Contrary to PV and wind, it provides on-demand renewable power. When combined with CO₂ capture and storage, it can [scrub carbon from the atmosphere](http://roadtoparis.info/2015/03/30/will-negative-emissions-technology-get-us-to-2-degrees/?ref=blog.indecol.no) and place it underground. Burning short-rotation coppice, such as [willow](https://en.wikipedia.org/wiki/Willow?ref=blog.indecol.no) and [miscanthus](https://en.wikipedia.org/wiki/Miscanthus?ref=blog.indecol.no), to produce power can also lower the net greenhouse gas emissions of biopower. In these ways, the health effects of burning biomass can be reduced. ![](https://cdn.theconversation.com/files/159649/width754/image-20170306-20739-ndp41q.jpg) Making power from bioenergy, such as wood chips, has carbon emissions and other air pollutants. Capturing carbon and pumping it underground improves its environmental footprint. [Oregon Department of Forestry](https://www.flickr.com/photos/oregondepartmentofforestry/14492838086/in/photolist-o5FzQJ-6nMQsW-qwseB3-cdkAAA-jyk1zr-5EyEX5-eQcjHd-9zfV7t-uTTQbQ-uMzvr-4U6RhP-pi2dzd-b7qmzi-65BCRS-4hSLAU-5PgquD-5Eun9i-5Eun8p-wRJo5b-4nc9yY-4wGdak-5Eunaz-aFH8GZ-gZkD9y-65Q7Uj-gZkCjs-da7GXg-ntxXWi-6HLrvg-dGRmwy-khJSXc-asqZKX-dn3KpF-gZkqEN-GWQS5-7Jf5TG-adHke6-6ExLU7-ppYB1B-sdRq54-5ZoWAR-9cjB84-pPMK2a-9Vx44H-6baKir-8cgdFs-7gZnwu-q2DvZU-ebxED4-oNTPC?ref=blog.indecol.no), [CC BY](http://creativecommons.org/licenses/by/4.0/?ref=blog.indecol.no) Yet, the land use required to grow even these fast-growing plants dwarfs the land use of other power sources. This has significant ecological implications. As measured by species lost per kilowatt-hour generated, we found that the ecological damages of biomass are comparable to that of coal and gas. So while it does deliver benefits from reduced greenhouse gas emissions, biomass power becomes more favorable to ecosystems only when used [with carbon capture and storage](https://en.wikipedia.org/wiki/Bio-energy%5Fwith%5Fcarbon%5Fcapture%5Fand%5Fstorage?ref=blog.indecol.no), we concluded. Climate mitigation strategies can provide a rare opportunity to reduce not only carbon emissions but also a wide range of environmental problems. However, deployment of low-carbon technologies should avoid sensitive habitats in order to fully realize their environmental benefits without triggering unintended consequences. While most people recognize that solar and wind are low-carbon energy sources, bioenergy and carbon capture and storage also have an indispensable role in basically all scenarios where countries rapidly reduce carbon emissions. Our results indicate that we need to search for ways to use these technologies while minimizing the harm to ecosystems. It is not just about whether we employ clean energy, but what technologies, where and how.

Being composed mostly of cement and steel, we would expect their production to cause a lot of greenhouse gas emissions. [In a new paper, we offer a first detailed analysis of the carbon footprint of gross fixed capital formation across countries and sectors](http://dx.doi.org/10.1111/jiec.12532?ref=blog.indecol.no). The picture that emerges is interesting because of some small surprises. ![](http://carbonfootprintofnations.com/wp-content/uploads/2017/01/Sodersten_CFofCapitalPerCountry2007-1.png) Share of capital formation in the final demand and carbon footprint of different countries. Source: [Journal of Industrial Ecology](http://dx.doi.org/10.1111/jiec.12532?ref=blog.indecol.no) First of all, capital is big. Capital formation constitutes about one quarter of gross global product in monetary terms. It causes about 30% of global greenhouse gas emissions. Leaving it out is a pretty big oversight. Second, capital formation varies across countries. The country with the highest capital formation over the past decade was China, where it constituted 44% of GDP in 2007 and caused 57% of the carbon footprint. In developed economies, capital formation constitutes only about 20% of GDP. Third, the carbon intensity of capital formation varies depending on what capital goods countries and industries invest in. While construction and machinery are carbon intensive, software and business services are not and ICT hardware has an average carbon intensity. Globally, construction accounts for half of capital formation and 60% of its footprint. In wealthier countries, capital formation is less carbon intensive than household consumption. Fourth, capital formation increases with GDP across countries. This is maybe not surprising: affluent people save more. However, despite purchasing more software and business services, rich countries also keep investing in buildings and roads. Across countries, the carbon footprint of capital formation increases by 83% for each doubling in GDP per capita, measured on a purchasing power parity basis. China is an outlier in this picture, having a carbon footprint of capital per person higher than France or Great Britain. This increase of the carbon footprint of capital with wealth occurs in spite of investing in cleaner types of capital and having cleaner technology. Most of the capital goods are purchased domestically. We investigated two groups of countries, those with the highest and lowest carbon intensities of capital formation, and found that in both groups, two thirds of the value added associated with capital formation was domestically produced. However, the location of GHG emissions diverges: In countries with a high carbon intensity of capital, most of the emissions occurred domestically, while in countries with a low carbon intensity of capital, three quarters of the carbon footprint was associated with imports. That is quite a stunning divergence! In economies with a clean energy mix and a high energy efficiency of production, one would expect imports to have a disproportionate share of the carbon footprint, but the differences observed for capital are especially egregious. In [Prosperity without Growth](https://www.routledge.com/Prosperity-without-Growth-Economics-for-a-Finite-Planet/Jackson/p/book/9781849713238?ref=blog.indecol.no), Tim Jackson argues that investing in assets and infrastructure was an important step in the transition to a sustainable economy (p.177 f). We find that investments are just as or even more polluting than consumption, so that this strategy, per se, is not one that will solve our environmental problems. His list of suggested investments, of course, focuses on investments that would enable a more sustainable living, such a renewable energy, public transport, and energy-efficient buildings. We agree that such investments are required, but would like to point out that capital formation as such is polluting and that hence, this pollution needs to be considered when looking at the whole picture. Finally, I would like to close by reflecting on my own field. When considering the carbon footprint of products or services, the carbon required to produce the machinery that produces the products we consume, the carbon required to lay the roads and build the ports, warehouses and shopping malls that deliver these products to us are usually not considered in the assessments, independent of whether life cycle assessment or input-output analysis is used for the quantification. We have now provided an estimate of the potential magnitude of the resulting error. It is too large to be ignored. *Source*: Södersten, C.-J., R. Wood, and E. G. Hertwich. 2017\.

The figure shows a clear trend, but also some significant outliers. The capital invested in rich countries has lower CO2 emissions, as it consists more of software, and it is produced with cleaner technology. Nonetheless, the sheer volume of investment is higher, leading to this effect.

El pedido puede cerrarse después de confirmar las instrucciones de conservación para estampados y bordados. In 2012, [I reviewed a best-selling book](https://blog.indecol.no/germany-solar-influence-on-climate-in-public-spotlight/) by two German scientists critical of the greenhouse effect as a theory explaining recent temperature rise. These scientists claimed that it was cosmic radiation, instead. Part of public attraction of the book was the prominence of the first author, Fritz Vahrenholt, a former environmental activist, chemist-turned-politician and later corporate big-wig at Germany’s largest electric utility, another part was the scientific appearance of the argument, with a book full of figures and references, but written in accessible language. For me, finding a consistently argued contrarian case was welcome, as it allowed me to understand and probe the intellectual content of that position. I had been faced with various contrarian arguments often contradicting each other and no alternative theory to explain the phenomenon of global warming or other climatic developments. Probing the book, I identified inconsistencies of the presented arguments, e.g. about feedback mechanisms, contradiction between observations in the scientific literature and those reported in the book, a very selective representation of the available evidence, and gross misrepresentations of a few of the cited articles. Sure of their alternative theory, the authors predicted that given the expected development of cosmic radiation in response the sun’s regular cycles, temperatures would decline. In fact, they predicted a measurable decline to levels seen in the 1990s already by 2015\. I am afraid the picture I took at the time of the figure in question was not the sharpest, but you can get a good impression. What has happened was exactly the opposite. After 2014 already setting a new temperature record, 2015 is now the warmest year on record by a good margin. This new evidence clearly contradicts the predictions made by the sceptics. They were very sure of themselves. I wonder what they say now. ### Industrial Ecology – Reflexions URL: https://blog.indecol.no/industrial-ecology-reflexions/ Last updated: 2026-07-16T21:38:58.000Z ![The entire team of PhD students, PostDocs and professors on the steps of the main building, 17 October 2014](http://carbonfootprintofnations.com/wp-content/uploads/2015/09/15771182305_12d70bfb18_z-300x200.jpg) The entire team of PhD students, PostDocs and professors on the steps of the main building, 17 October 2014 In 2003, I moved to Trondheim to become Director of the [Industrial Ecology Programme](http://www.ntnu.edu/indecol/?ref=blog.indecol.no) (IndEcol) of the Norwegian University of Science and Technology (NTNU). In 2015, I have [moved on](https://environment.yale.edu/news/article/edgar-hertwich-global-leader-in-industrial-ecology-joins-fes-faculty/?ref=blog.indecol.no) to head the [Center for Industrial Ecology](http://cie.research.yale.edu/?ref=blog.indecol.no) at Yale University, following [Tom Graedel](https://environment.yale.edu/profile/graedel?ref=blog.indecol.no), the founding president of our [society](http://is4ie.org/A-Note-from-the-Presidents?ref=blog.indecol.no). This transition provides an occasion to reflect on NTNU’s contribution to the field and on opportunities for future development. Industrial Ecology as a scientific field coalesced in the 1990s going back to beginnings in the 1960s and 1970\. As an interdisciplinary activity strongly influenced by industry, industrial ecology was simultaneously 1. built on an explicit systems approach, borrowing both from biology and engineering; 2. an analogy between nutrient cycles in nature and material cycles in industry, analyzing “industrial ecologies” (specific arrangements of material cascading and looping), with a normative implication that circular material flows in the economy were more sustainable; 3. a pro-active environmental attitude by industry. Rare among academic fields dealing with the environment, industrial ecology accords industry agency in solving environmental problems and sees it not just a cause of problem and responding to government regulations. At NTNU, the Industrial Ecology programme was initiated on the request of industry, with Norwegian Hydro’s Vice President [Rolf Mastrander](http://homepages.uwp.edu/crooker/research/systems/articles/2000-mastrander-etal-jie.pdf?ref=blog.indecol.no) in the leadership. Mastrander became the first industry-sponsored Adjunct Professor of Industrial Ecology in the second half of the 1990s, a position later held by Kjell Øren, also from Hydro and the World Business Council on Sustainable Development. An international evaluation of IndEcol after its initial five years praised the work of founding director Professor [Helge Brattebø](https://en.wikipedia.org/wiki/Helge%5FBratteb%C3%B8?ref=blog.indecol.no) and his team of co-conspirators and stated that NTNU, offering the first organized educational program, was a true pioneer in the field. For me, the position at NTNU offered an opportunity to realize research ideas of consumption-based accounting for environmental pressures and of evaluating the potential contributions of emerging technologies to reducing these environmental pressures. It also offered an opportunity to expand on and permanently establish the original project organization, and I initially did not realize how much time I would dedicate to this. Fortunately, NTNU’s engineering deans took a positive attitude towards our field, creating new professorships and financing PhD students. In return, they were awarded with a highly productive and internationally well-recognized unit. In a [research assessment](http://www.forskningsradet.no/en/Article/Evaluation%5Fof%5Fbasic%5Fand%5Flongterm%5Fresearch%5Fwithin%5Ftechnology/1253995805470?ref=blog.indecol.no) conducted for the Research Council of Norway (RCN), IndEcol was ranked third out of 64 research groups in engineering, beaten only by two well-funded heavyweights. In particular, the assessment emphasized the synergy achieved among different topics and projects and praised our societal impact, evidenced by the contributions to the Intergovernmental Panel on Climate Change (IPCC) and the creation of spin-offs. In preparation for the research assessment, the RCN also commissioned a [bibliometric study](http://www.forskningsradet.no/servlet/Satellite?blobcol=urldata&blobheader=application%2Fpdf&blobheadername1=Content-Disposition%3A&blobheadervalue1=+attachment%3B+filename%3D%22Bibliometricreport-Finalversion.pdf%22&blobkey=id&blobtable=MungoBlobs&blobwhere=1274506527829&ssbinary=true&ref=blog.indecol.no) of scientific papers published by Norwegian engineers in the peer-reviewed literature, which identified IndEcol as the most cited group in terms of total citations. It listed the Carbon Footprint of Nations as the single most cited study published in the considered time period 2009-2013\. The analysis also showed that work published by the group was on average cited 2.5 times as much as other papers appearing in the same journals, an indicator of the impact that our work has in the scientific community. NTNU is well placed to continue making substantial contributions. - IndEcol has a substantial pool of talent. As the research assessment emphasized, IndEcol researchers “have very good overall performance with some excellent individuals”. IndEcol researchers will continue to provide leadership in scientific societies and journals, an IEA task force, and the UNEP-SETAC Life Cycle Initiative. - IndEcol has an excellent educational program. Its International MSc program in industrial ecology provides a very solid training especially in the quantitative analysis approaches characteristic of the field. IndEcol also educates engineering Master students and receives a substantial number of visiting students from other European universities. These MSc students contribute to ongoing research and provide access to talent. - Environmental issues will continue to be a serious concern and industrial ecology approaches are increasingly recognized as being essential to addressing these problems. Industrial ecology has seen the start of a convergence of traditionally separate methods and approaches. IndEcol has contributed to this trend; yet I am convinced that the potential for further synergies is large. We have developed scenario approaches based on either material cycle dynamics or energy scenario models, yet a combination of those two would provide a real breakthrough. IndEcol scientists have produced models of the global economy resolved also to specify und understand emissions and resource use at the national level while others have worked on spatially explicit impact assessment especially on ecosystems, but not yet combined those approaches to model the environmental impacts arising from specific value chains and product baskets. IndEcol researchers have studied different climate impact mechanisms of biomass utilization but not yet connected these to broader scenarios of energy and material consumption. All this research would help us to answer research questions important either for policy decisions or for individual companies and authorities. What opportunities does a circular economy hold for climate change mitigation? How do specific action options of specific industries affect future resource access? We demonstrated pollution benefits of shifting to a low-carbon electricity supply, yet do such benefits also occur from other climate change mitigation strategies? The world economy is continuing a tectonic shift in the utilization of resources, so what are the implications of this shift for resource owners, like Africa, and regions dependent on resource imports, like Europe? Research activities need to reach a certain scale to be able to tackle such questions, as they require a systematic build-up of research infrastructure in terms of databases and software and a combination of skills that are usually not held by a single individual. To take advantage of these research opportunities and the potential synergies that lie in the complementary competences of IndEcol staff, the new IndEcol leadership will have to find funding for larger projects involving multiple PIs. Unfortunately, I have not been able to generate such funding. Our proposal for a Centre of Excellence received good scores but was not funded. Since twice rejecting proposals to fund the work that lead to the Carbon Footprint of Nations, the Research Council of Norway has consistently failed to support larger projects in our domain. Others may be more capable of maneuvering the politics of research funding that invariable affects small countries. I have enjoyed many aspects of living in Trondheim. It has great outdoors, 100s of km of hiking trails and ski tracks, good but expensive food and decent cultural offerings. I really should have spent more time in the mountains! Norway is a well-run and extremely cohesive society where family life is important and many are active in volunteer activities; a country with a high social capital. Like Berkeley, Vienna, Zurich, a great place to live, and I still manage to move on. Other places have other attractions. All of us are visitors on this beautiful planet, and we may as well visit a few places to see what it is like. I would like to thank my former colleagues for their excellent collaboration and wish them good luck with their further path.

While two billion people still lack access to clean cooking fuels and one billion lacks access to electricity, the number of energy-poor in Europe is small and energy is both reliable and affordable for most European consumers. The real benefits of modern energy become apparent only when we experience power outages, gas embargoes or when we see ![BalancingEnergyEconomy150120](http://carbonfootprintofnations.com/wp-content/uploads/2015/01/BalancingEnergyEconomy150120-300x169.png) what fraction of the household income energy-poor are willing to pay for energy. Research on the social metabolism of societies has demonstrated that [access to fossil fuels was essential to allow the growth of urban centers](http://anr.sagepub.com/content/early/2014/01/08/2053019613518033.abstract?ref=blog.indecol.no) even before invention of the steam engine and how it has fueled the industrial revolution and [economic growth](http://www.e-elgar.co.uk/bookentry%5Fmain.lasso?id=13324&ref=blog.indecol.no) ever since. **The use of fossil fuels, however, has substantial environmental costs**. In a [study for the International Resource Panel](http://www.unep.fr/scp/publications/details.asp?id=DTI/1262/PA&ref=blog.indecol.no), we assessed the main drivers of a large set of environmental problems in terms of industry sectors, products and materials. We found that fossil fuel utilization was the number one cause of most pollution-related environmental problems, while agriculture and food production stood as the major cause for habitat change, biodiversity loss, and a significant contributor to ecotoxicity and overfertilization of the environment. Energy not only stands for 80% of the climate problem, it also causes the exposure to fine particulate matter with significant health impacts especially but not only in developing countries, the formation of smog, significant pollution associated with the extraction and transport of fossil fuels, and more. As people become wealthier, they are increasingly [less willing to have their lives cut short by five years](http://www.pnas.org/content/110/32/12936?ref=blog.indecol.no) because of cheap energy supply, as we see in China today. **The environmental costs of fossil fuel use should be the deciding factor in determining our energy policy**. Climate costs affect mostly future generations and the poor, which have little political clout today and cannot force decision makers to internalize these costs. Fortunately, as our recent research has shown, [low-carbon power sources also lower other types of pollution](http://www.pnas.org/content/early/2014/10/02/1312753111.abstract?ref=blog.indecol.no) which cause more immediate damages. This dual benefit provides an additional rationale for climate policies. **In the area of solar and wind energy; Europe has been at the forefront** creating a market for these technologies, thereby driving costs down and making these energy sources cost-competitive in some markets, even if the environmental costs of fossil fuels are not yet fully internalized. Even if China has now taken over as a technology supplier, it would not have happened without European leadership. Solar and wind energy are intermittent. Good resources are sometimes far from demand centers. **Extending electricity grids and removing regulatory barriers to create a single energy market in Europe** can overcome some of the challenges posed by intermittency and remoteness. Our research shows that transmission lines and subsea cables, while adding to the pollution impact of renewables, do not compromise the environmental edge renewables have over fossil fuels. Even with extensive [transmission networks, in North Sea](http://dx.doi.org/10.1007/s11367-014-0709-2?ref=blog.indecol.no) or [across Europe](http://dx.doi.org/10.1016/j.energy.2014.03.072?ref=blog.indecol.no), RES come out as very attractive from a pollution perspective compared to today’s system. However, **impacts on the landscape** become a problem – people do not want to have all places full of windmills and transmission towers. The variability of RES may be a real challenge to effective utilization if not sufficient transmission capacity is built. We should hence also explore alternative options to address variability through energy demand reduction, peak shaving, and various forms of energy storage. Technological progress, including in smart grids and energy storage, will reduce the costs and hassle associated with these strategies and will make them more attractive. They may also have clear environmental benefits, which, however, need to be demonstrated. **Energy and climate policy**, GE Europe CEO Stephan Reimelt claimed in the discussion, **have become a major source of volatility for companies, providing a challenge to businesses**. The way of internalizing social costs is important. Instead of imposing a carbon tax or an effective ETS with predictable carbon costs, Europe has followed a second-best strategy of protected markets, subsidies, and regulation. This strategy has been successful in stimulating necessary technology development and increasing energy efficiency, but it is not reducing emissions enough. The second-best approach has resulted in inconsistent and varying signals to companies. The system thus exposes investors to unnecessary policy risks, thereby adding to the financing costs of the energy transition. [Transmission system operators](https://www.entsoe.eu/major-projects/ten-year-network-development-plan/tyndp-2014/Pages/default.aspx?ref=blog.indecol.no) call for a stable investment climate to reduce the risk to those making huge investments. **Internalizing environmental costs can provide the stable investment climate requested by industry.** The EU should introduce a price floor for the emissions allowances in its emissions trading system (ETS) by charging a minimum price for handing out the allowances. Better still, [it could replace the ETS by a carbon tax](http://www.economist.com/news/leaders/21639501-fall-price-oil-and-gas-provides-once-generation-opportunity-fix-bad?ref=blog.indecol.no). A more predictable price of carbon would reduce the market volatility for energy efficiency, transmission and other energy investments and thus reduce the costs of financing the energy transition. It will also reduce the need for regulation, thus further reducing the costs to business. Today, some electric utilities in Europe are in a difficult economic position, as[ the split of Germany’s EON shows](http://www.ft.com/intl/cms/s/0/9c358caa-78cf-11e4-b518-00144feabdc0.html?siteedition=intl&ref=blog.indecol.no#axzz3PXQrFZnn). They have **created an overcapacity of fossil fuel fired power plants**, because they expected more demand growth and maybe did not believe the planned renewable generation would be realized. Their investment decisions were based on a higher carbon price, but their own overestimates for required emission allowances are to blame for the glut in the ETS. Utilities today complain that guaranteed feed-in tariffs for renewables are to blame for their poor return on investment, but both feed-in tariffs and EU renewable energy targets were in place when they invested in the most recent fossil capacity additions. Sure, few have predicted the shale gas revolution and its effect on the price of coal, so gas was a poor bet. Higher carbon prices improve the position of gas, but it would not go all the way making it competitive with coal today. Right now, some utilities lobby for capacity payments – a way to subsidize fossil fuel power plants in a manner comparable to the protected markets for renewable power. I am not convinced that more subsidies are the right decision.

Increased pressure in the pursuit of climate protection is still required to reach the 2°C Target. **Carbon Budget: Trillion tons of CO2** The report from the *Intergovernmental Panel on Climate Change (IPCC)* on the climate climate system launched last year has a clear message: emitting [more than one trillion tons](http://www.nature.com/nature/journal/v458/n7242/full/nature08017.html?ref=blog.indecol.no) of carbon dioxide from fossil fuels risks moving us far beyond the target of limiting global warming to [*2*°C](http://news.nationalgeographic.com/news/energy/2014/02/1402277-global-warming-2-degree-target/?ref=blog.indecol.no) *above preindustrial level*. This carbon budget stems from the climate sensitivity – the correlation between the increased concentration of greenhouse gases and the resulting temperature rise. ![Following the climate sensitivity, temperature increases as we put more carbon dioxide into the atmosphere. The level of increase is largely independent of the rate of emissions; it depends on the cumulative amount emitted. A higher emissions rate means the temperature will increase faster. If we want to limit the warming to a certain level, one can read the carbon budget (cumulative emissions we are allowed to produce) off the figure. Credit: IPCC WG1.](http://carbonfootprintofnations.com/wp-content/uploads/2014/11/Picture1-300x239.jpg) Following the climate sensitivity, temperature increases as we put more carbon dioxide into the atmosphere. The level of increase is largely independent of the rate of emissions; it depends on the cumulative amount emitted. A higher emissions rate means the temperature will increase faster. If we want to limit the warming to a certain level, one can read the carbon budget (cumulative emissions we are allowed to produce) off the figure. Credit: IPCC WG1. One thousand billion tons sounds tremendous. But think again! In 2050 we will have a nine to ten billion humans on earth; the budget is equivalent one hundred tons per person. If we give ourselves hundred years to learn how to live without a net carbon dioxide emission, that is a ton per year for each of us. Currently the greenhouse gas emissions in Norway count about ten tons per person, adding the carbon footprint, which includes imported goods and international flights, the average rises to approximately fifteen tons per person. The global average is seven tons. At the current emission rate, we will have consumed the *budget in 20 years.* **Rapidly increasing emissions** Unfortunately the development is heading in the wrong direction. In the 2000s greenhouse gas emissions increased more rapidly than previous: 2.2 % per anno compared to 1.7% per anno in the period 1970-2000. Combustion of coal – the *dirtiest* energy source – rose faster than otherwise energy production. China’s state-run capitalism boosts growth through investments in mines, power plants, infrastructure, buildings and machinery, all financed by savings of relatively poor Chinese. It is easy to feel blue on behalf of the climate! However, the picture is not entirely devastating. In my work with the *IPCC-report* on climate change mitigation, I have discovered a series of bright spots. Perhaps we have made more progress with climate protection than the pessimists among us realize? Here are my reasons for optimism. ![The atmospheric CO2 concentration has increased at an unprecedented rate in the 2000s due to a rapid rise in population and economic output and a failure to shift to low-carbon energy sources.](http://carbonfootprintofnations.com/wp-content/uploads/2014/11/SPM6-300x248.png) The atmospheric CO2 concentration has increased at an unprecedented rate in the 2000s due to a rapid rise in population and economic output and a failure to shift to low-carbon energy sources. **Testing of instruments on a large scale** While the summary report, that is the abstract for policy makers, is rather cautious in its discussion of instruments for climate protection, the chapters of the main report offers more interesting reading. It describes climate policy measures implemented by countries, cities, regions and multinational organizations. The instruments include systems with emission constraints and trade with emission allowances such as the EU emissions trading system (EU ETS) that Norway also is a part of, various kinds of support for renewable energy and energy efficiency improvements in amongst others China and India, regulations and voluntary agreements for more efficient cars, airplanes, washing machines, and much more. Quite many climate policy measures have been implemented since the publishing of the former climate report in 2007\. Not every measure works as good as foreseen; but at least we have the opportunity to harvest important learnings that may become the basis for a more effective policy in the future. **We can live without fossil energy – can we?** If we search to limit global warming we need energy technologies producing little or no greenhouse gas emissions. Energy Scenario models that the IPCC has applied in several reports indicate that renewable energy will be an important element of climate protection. Previously it seemed rather optimistic, given that solar energy only could supply relatively small cabins with light. Back then wind energy only had an important role in little Denmark. Today, however, utilities built wind farms that produce as much power as coal power plants. (For a 6000 MW windfarm in the Gansu province in China, see [here](http://en.wikipedia.org/wiki/Gansu%5FWind%5FFarm?ref=blog.indecol.no).) Engineers have designed solar thermal power plants can supply electricity based on storage of heat. [One such plant produces as much electricity as the controversial gas-fired power plant at Mongstad](http://en.wikipedia.org/wiki/List%5Fof%5Fsolar%5Fthermal%5Fpower%5Fstations?ref=blog.indecol.no). The IPCC report informs us that the capacity of renewable energy production in 2012 increased by 105 gigawatts – roughly equally distributed between solar, wind and hydropower. Solar power continues its growth in 2013\. One gigawatt is the effect of one large atomic power plant, or four times the power rating of Mongstad. A comparison with the IEA’s 2°C scenario shows that we have already achieved the required rate of expansion renewable energy production. We just have to continue on the same level. The maturation of renewable energy technologies ought to be celebrated as a climate politic success! Recent years we have seen the arrival for electric cars that are attractive, comfortable, and with acceptable range. Electric cars are only environmental friendly if supplied with clean electricity; reducing energy consumption in battery production is imperative for climate mitigation. Still, electric cars will become a technology that offers us more opportunities to face the transport demands with fewer emissions than current cars do. In addition to various forms of state support, electrical cars are driven forward through customer interest in sustainable transportation. Meanwhile engineers have learned to build houses that barely consume energy for heating and identified new ways to reduce emissions through recycling of components and materials. I have also learned from the report that nuclear power is not as dangerous as I presumed; actually the human body is able to handle low-intensity radiation from accidents such as the Fukushima accident. The realization of a low carbon society still requires a number of technological innovations, but it appears that we can manage these challenges. It is less certain whether we really are able to apply all the environmentally friendly technology to reduce emissions. **Do we manage to use the technology to reduce emissions?** Coal consumption continues its rapid growth as coal is readily available and inexpensive to produce in regions experiencing high economic growth, such as China, Malaysia, Turkey, India and South Africa (f[igure](http://carbonfootprintofnations.com/wp-content/uploads/2014/04/SPM5.png?ref=blog.indecol.no)). The amount of emissions also grows because industrialized countries fail to reduce their emissions and import steadily more goods from coal dependent economies, mainly in Asia. While technology has presented us the opportunity to replace the use of fossil fuels through a combination of energy efficiency, renewable and nuclear energy – this is not what we use the technology for. We can stop global warming if we cease to use fossil energy without capture and storage of CO2. Of the many climate political instruments implemented, the reduction in the use of fossil energy has been the least successful. The European emission trading systems is based on the distribution of free emission allowances that has given large revenues to many industry actors. As a result of intensive lobbyism too many emission allowances have been distributed and the price has dropped close to zero. Meanwhile, financial support to fossil energy, good conditions for the fossil industry and other promoting measures that enhance fossil energy, continue. Gasoline is subsidized amongst in Brazil, India, Nigeria and many other places. The level of security in the coal mines in China and Turkey is so low that hundreds of lethal accidences occur every year. NATO and the United States maintain an extensive and pricey presence in the Middle East that serves to ensuring the continued access to petroleum. In Norway, the petroleum industry opposes the electrification of oil platforms at Utsirahøgda and has seemingly failed implementing CO2 capture at Mongstad. Unless we confront the support for fossil energy and at the same time manage to gain approval for effective measures that restrict the use of fossil fuels, emissions will continue to increase. **We choose the path** Even though the latest report from the International Energy Agency (IEA), [*Energy Technology Perspectives 2014*](http://www.iea.org/etp/etp2014/?ref=blog.indecol.no) is very optimistic regarding renewable energy and predicts a bright future especially for solar power, it is not so that renewable energy simply emerges by itself. The financial crisis has reduced the investment in renewable energy production and has worsened conditions in some pioneering countries such as Spain. In 2013, investments in renewable energy production had dropped by a quarter from the peak in 2011 according to Bloomberg. In Germany, the value of renewable energy is decreasing due to a large fluctuating production that result in energy prices close to or below zero when the production is high. Essential for renewable energy in the time to come is two things. First, new markets and countries must acquire framework conditions for implementation of renewable energy. For the climate it would be desirable that this would happen through quota markets or emission taxes rather than subsidies. Second, we must increase our effort to develop and implement solutions to address variable energy production from renewables. Part of the solution lies in power plants with more operating hours (wind power at sea rather than on land) and sources that vary independently of sun and wind, such as wave and tidal power. Further, energy systems can be adapted to variable energy supply through flexible demand, more transmission capacity over larger areas, and energy storage. Maybe some of these alternatives seem somewhat unrealistic? Possibly just as unrealistic as gigawatt-scale solar power plants seemed to be in 2007? Renewable energy is not enough. We must also scrutinize emissions from industry, transport, agriculture and deforestation. The IPCC has examined novel options, such as recycling of building components, spatial planning as a tool to reduce the need for transport, restructuring of nutrition away from the high and unhealthy meat and dairy consumption, reducing food waste, and carbon storage in products. Many of these solutions have different advantages, from better health and more leisure time to the preservation of natural resources. It is hard to see that we could manage foregoing these options if we want to continue economic development for a growing population and limit climate change. I think we should regain courage by the successful development and the introduction of new energy technologies such as solar power, electric cars, and passive houses. These options provide us great opportunities! We should also learn lessons from how various measures have been more or less effective. It is time to let technology replace fossil energy use. *This article appeared first in Norwegian, initially in Bergens Tidene,* [*Adresseavisen*](http://www.adressa.no/meninger/kronikker/article9496063.ece?ref=blog.indecol.no) *and in the full version in* [*2/C*](http://energiogklima.no/kommentar-analyse/ny-teknologi-gjor-togradersmalet-mulig/?ref=blog.indecol.no) A national team shirt can become part of how supporters remember a tournament because fans often compare the emotional pull of old and new designs.

By [Edgar Hertwich](http://carbonfootprintofnations.com/author/edgar-hertwich/?ref=blog.indecol.no), [Thomas Gibon](http://www.ntnu.edu/employees/thomas.gibon?ref=blog.indecol.no) and [Anders Arvesen](http://www.ntnu.edu/employees/anders.arvesen?ref=blog.indecol.no), NTNU The use of fossil energy sources has made it possible for cities, population and prosperity to grow. It has also led to the pollution of air, water and soil. The main product of the combustion of fossil fuels is carbon dioxide, a gas that holds back the Earth’s heat radiation so that the surface and ocean temperature increases. To prevent dangerous anthropogenic warming, we have to either switch to non-fossil energy sources or adopt clean technologies that prevent carbon dioxide from reaching the atmosphere. Fossil energy is not only the main cause of climate change, but is also the most significant source of air pollution and an important cause of several other environmental problems. As many people die from air pollution every year as in battlefields of World War II: 7 million per year, according to the World Health Organization. About half of these deaths are caused by fossil fuels; a tenth by fossil power plants. In a new study, we investigate how the replacement of normal coal and gas power with climate friendly alternatives affects the pollution and hence damage to humans and ecosystems. The production of electricity from renewable sources causes little or no emissions directly, but the construction, maintenance and scrapping of plants such as wind farms requires materials, electricity, and transport. These activities lead to emissions, which can be quantified using life cycle analysis. In [our study](http://dx.doi.org/10.1073/pnas.1312753111?ref=blog.indecol.no), we analyzed solar, wind, geothermal and hydropower plants and compared them to different types of coal and gas fired power plants. Technology experts in several countries have contributed data and assessments. We have both compared the [environmental impact of producing a single kilowatt hour](http://public.tableausoftware.com/profile/?ref=blog.indecol.no#!/vizhome/ElectricityTechnologyComparisonsPNAS2014/UnitDashboard) and assessed the global environmental effects of a reorganization of the entire global energy supply. Our study calculates the amount of materials necessary to produce power. We conclude that wind power and solar thermal energy demand up to ten times more steel and concrete than coal and twenty times more than gas. Solar cells need much copper for wires and aluminum for frames. It’s not just the final production of these materials results in emissions, but also the extraction of raw materials, processing and transport. In spite of the large quantity of materials and equipment required, renewable energy causes much less pollution than fossil fuels. Thermal solar energy, PV, onshore and offshore wind turbines are clearly better than coal on all environmental indicators we have examined, and beat gas power on several indicators. Many hydroelectric and geothermal power plants are also environmental champions, although not all such projects are good. The use of carbon capture and storage to clean fossil fuel power plants results in a moderate increase of emissions other than carbon dioxide, compared to plants without capture. Even though the demand of space for renewables is often emphasized, the increase deployment of renewables would lead to lower space requirements than a continued expansion of fossil based power due to the large land use of coal mining. The comparison of our various global future scenarios shows that a further development of fossil power production to meet a growing demand, as foreseen in the IEA Baseline scenario, will lead to a doubling of air pollution to 2050, even the use of modern and more efficient fossil power plants. It will also lead to a doubling or tripling of various types of pollution to water and soil that are harmful to ecosystems. A global adoption of low carbon power generation, as foreseen in the IEA 2 degree scenario, will however stabilize air pollution and reduce emissions of other pollutants, although the power production almost doubled. Further reductions in emissions are possible if we use more renewable energy and less carbon capture to meet emission targets. Our study shows that a global transition from fossil to renewable electricity will reduce not only global warming but also limit damage to human health and ecosystems. While some challenges remain on the way to power systems that rely on a large degree of variable renewable energy sources, technologies such as compressed air or thermal energy storage offer part of the solution.

It says that it is urgent to begin reducing emissions, otherwise we will not be able to stay below the articulated limit of two degree temperature rise. Sure, but that was already the main message of the fourth asssessment report in 2007\. Having contributed to this report as a lead author of the energy chapter, I have made my personal list of most important findings. Key findings – IPCC WGIII AR5 1\. The past decade has seen an unprecedented rate of increase in Greenhouse gas (GHG) concentrations in the atmosphere as a result of the global rise in emissions. The primary cause for the rise in emissions was the rapid coal-fueled industrialization and urbanization of emerging economies, combined with continued high emissions in industrialized countries. The carbon footprint of rich countries has kept rising, but mainly due to the increased import of emissions-intensive products from middle income countries (see figure; for [country classification](http://en.wikipedia.org/wiki/List%5Fof%5Fcountries%5Fby%5FGNI%5F%28nominal,%5FAtlas%5Fmethod%29%5Fper%5Fcapita?ref=blog.indecol.no)). The world is now on the upper end of the emissions scenarios considered in earlier IPCC assessments. ![A "Glen Peters" chart showing the emissions embodied in trade and how carbon footprints (broken lines) have developed over time.](http://carbonfootprintofnations.com/wp-content/uploads/2014/04/SPM5-219x300.png) A “Glen Peters” chart showing the emissions embodied in trade and how carbon footprints (broken lines) have developed over time. 2\. A strident development of low carbon technologies demonstrates now the viability of climate mitigation. Progress includes substantial reductions in cost and initial market penetrations of technologies such as wind power, solar heat and power, highly efficient building shells, and electric vehicles. These technologies present alternatives to established technologies based on fossil fuel combustion. Our capacity to build solar and wind power plants is now nearly large enough to achieve the share of renewables of mitigation scenarios. 3\. A range of national, regional and local climate policies have been implemented. While these policies have been insufficient to halt the global rise in emissions, they provide important experiences with various policy approaches and instruments, such as emissions trading, carbon taxes, technology standards, and market penetration programs. They also constitute an important reason for the technological progress achieved. 4\. Limiting the global average temperature increase to the internationally agreed target of 2 degrees centigrade or even 3 degrees above the preindustrial levels requires the cessation of CO2 emissions from fossil fuel combustion and industrial processes already within this century. Considering the long investment horizons of infrastructure and industrial equipment, a continued increase of CO2 emissions for a decade or more will most likely results in an “overshoot” of both atmospheric concentrations and temperature above the 2 degree target. Reducing the global average temperature back to 2 degrees above preindustrial level would require a massive employment of so-called negative-emissions technologies, such as bioenergy with CO2 capture and storage or CO2 removal from the atmosphere, by 2070\. These are unproven and expensive technologies, shouldering future generations with substantial costs. 5\. Replacing fossil fuel utilization by energy efficiency and a range of renewable and nuclear energy technologies, if properly chosen, may lead to a substantial reduction of pollution and associated health and ecological impacts, as well as a reduction of fatalities related to severe accidents. The extraction and utilization of fossil fuels, in particular of coal and unconventional oil, causes a range of serious environmental and occupational health and safety issues. Low-carbon energy technologies also cause such impacts, but rates of pollution and severe accidents are commonly lower. In addition, for many countries, reducing fossil fuel use will result in a reduced dependency on imported resources. Climate mitigation may hence help societies to achieve other social objectives, such as clean air and autonomy. 6\. The efficiency of industrial production processes and transportation technologies has increased in the past decades. Gains from a further improvement of individual technologies, while important, are by themselves not sufficient to deliver the necessary emissions reductions, and more systemic solutions need to be achieved, such as urban design approaches to limit emissions from transportation and construction, or longer lived products, urban mining, reuse and recycling approaches to reduce emissions from materials production. The field of Industrial Ecology has delivered significant insights into these more systemic approaches to climate mitigation.

The sun peaked out under the clouds and the light was beautifully reflected by the water of [Nesjøen](http://en.wikipedia.org/wiki/Nesj%C3%B8en?ref=blog.indecol.no), while reindeer was munching away on delicious blueberries a little further down the ridge. The reservoir below contrasted to the barren land on the other side, making it more tranquil and interesting at the same time. No wonder that hydropower has a good reputation as an environmentally benign source of electricity, renewable and carbon-free. But is it really? The answer turns out to be: it depends. One of the more remarkable environmental impacts of hydropower is the generation of the powerful greenhouse gas methane (CH4) from the rotting of organic material; plant matter inundated when the dam was filled as in the horrible case of the Balbina power station in the Brazilian Amazon ([Nature](http://www.nature.com/nature/journal/v444/n7119/full/444524a.html?ref=blog.indecol.no), [Wikipedia](http://en.wikipedia.org/wiki/Balbina%5FDam?ref=blog.indecol.no)), organic matter transported by tributaries, and algae and phytoplankton growing in the reservoir itself. The methane is generated when the water is depleted of oxygen, as it often happens in lower layers of still water. The amounts of methane and CO2 generated from the degradation of plant matter can be substantial; in [Balbina](http://onlinelibrary.wiley.com/doi/10.1029/2010JG001465/abstract;jsessionid=A0088EB1CA26BC05B0F751611734A154.d03t02?ref=blog.indecol.no), the amount of methane released corresponds to 2 kg of CO2 equivalents per kWh of electricity generated – twice the global warming impact as that of a coal fired power station. In addition, 8 kg of CO2 is released. The huge area of inundated dead trees – 1770 km2 for a mere 250 MW in capacity – indicates that Balbina may be an extreme, an outlier. How serious is the issue on a global scale? The Intergovernmental Panel on Climate Change (IPCC), in its [special report on renewable energy](http://srren.ipcc-wg3.de/report?ref=blog.indecol.no) published in 2011, had investigated the issue, but not offered a conclusion. Methane emissions were presented as they were measured, in grams of methane per square meter of reservoir surface. This provides an insufficient basis for comparison with other technologies. I have hence matched published measurements to the power generation and a number of potential explanatory variables such as reservoir area, latitude, and natural biological productivity of an area and analyzed the data. The findings of my work were recently published in [*Environmental Science & Technology*](http://pubs.acs.org/doi/abs/10.1021/es401820p?ref=blog.indecol.no). Here are some highlights: 1. For the global average hydro power station, methane emissions correspond to 70 gCO2 equivalent per kWh, which is more than the 2-40 gCO2/kWh from the construction of the power station. This is a lot less than the impact of fossil fuel power stations, but a lot more than the impact of wind power. 2. The emissions rate ranges by many orders of magnitude, in a distribution we call log-normal. Such a distribution has a peak near zero and a very long tail. Most hydropower stations are really benign, while the majority of emissions is created by a few plants. 3. The best predictor for the emissions rate is the reservoir area per unit of electricity output. If the reservoir measures below 0.1 square meter per kWh/year of electricity generation, you are on the save side. 4. Apart from the energy density, the age of the power station and the biological productivity of the area influence the emissions. Emissions go down with time at least for the first 10 years, as the biomass inundated by the reservoir decays. Naturally, one would expect that the amount of biomass and soil organic carbon originally present at the site are also important, but I had no data on that matter. However, the natural primary productivity of the area, the amount of biomass growth per land area, also plays a role, with dams on more productive land giving rise to higher emissions. Today, a lot of hydropower plants in developing countries receive support through the so called Clean Development Mechanism (CDM), a mechanism created through the Kyoto protocol to allow rich countries to off-set their emissions. Wisely, the CDMs are issued only to hydropower plants with a high power density. My research indicates that the threshold set for the funding is able to avoid some but not all highly emitting projects. The Vessingfoss power station at Nesjøen generates 44 GWh per year, the energy density is 0.75 m2 per kWh/y. I am not sure I could recommend the creation of this beautiful lake today. It is borderline. A football shirt can turn a season, a badge, and a colour scheme into part of supporter identity especially when supporters associate it with a title race or a European night. The history around Bayern Munich gives many shirts a meaning that goes beyond fabric and colour. When a shirt is chosen for a gift or collection, [Italy national team shirt for fans](https://www.camisetatienda.com/?ref=blog.indecol.no) remains a clear search phrase for readers comparing styles and versions. The matchday connection balances everyday wear with the meaning attached to a club or national side. ### Ecological tragedy, economic naiveté URL: https://blog.indecol.no/ecological-tragedy-economic-naivete/ Last updated: 2026-07-16T21:39:05.000Z ![](https://blog.indecol.no/content/images/2020/01/image-4.png) The tragic extinction of species, from the [black rhinoceros](http://edition.cnn.com/2011/11/10/world/africa/rhino-extinct-species-report/index.html?ref=blog.indecol.no) to plants remaining undiscovered, is unfortunately one of the hallmarks of humans on the planet. This week, the [Trondheim Conference of Biodiversity](http://www.dirnat.no/tk13/?ref=blog.indecol.no) celebrated its 20 year anniversary by gathering 400 scientists and international negotiators to an exchange of knowledge and ideas. The focus of this conference was on the economy and options for engaging companies and economic approaches to protect biodiversity, as well as making biodiversity relevant for economic decision makers. Key words are externalities, payment for ecosystems services and natural capital. In general, the gist of this effort is in the right direction and deserves to be supported. There are hopeful successful examples to follow, but at the same time the framework rests on an insufficient theory and some of the examples cannot be upscaled or generalized. There is no coherent strategy of how to protect ecosystems on a larger scale. I would like to offer a friendly critique and options for improvements. (1) A microeconomic approach is both insufficient and impractical. Microeconomics is concerned with markets for individual products and the prices and quantities of these markets; it treads decision makers as rational and well-informed. Higher extinction levels than those that would be *economically optimal*, according to this analysis as presented by [Ed Barbier](http://carbonfootprintofnations.com/2013/06/03/ecological-tragedy-economic-naivete/www.dirnat.no/attachment.ap?id=3232&ref=blog.indecol.no), occur because individual decision makers are not affected by the disappearance of the [ecosystem services](http://www.eoearth.org/topics/view/49575/?ref=blog.indecol.no) provided by a species – these services accrue to someone else. These economists hence engage in the valuation of ecosystem services, estimating the value provided by species through looking, e.g., at the value of crops dependent on pollination by bees, or the expenditure of visitors of a nature park, or by asking for a willingness to pay. Now they have taken the next step, promoting the correction of these externalities through payments in order to stop behavior that threatens species. [Robert U. Ayres and Ralph Kneese](http://www.jstor.org/discover/10.2307/1808958?uid=3738744&uid=2&uid=4&sid=21102280159281&ref=blog.indecol.no) have already in 1969 identified important shortcomings of the usefulness of the externality concept: it makes sense only when looking at certain individual decisions and if externalities are few and small. Environmental externalities, however, are pervasive and large. Just think about climate change, land use or the nitrogen cycle: practically every human activity causes these externalities, either directly or indirectly. The same is true for ecosystem services; we are all entirely dependent on them. Determining the right level of prices is hence problematic, as current prices are a poor reference; they are affected by externalities. Ayres and Kneese proposed an alternative research program; the field that has emerged reflecting their recommendations is now called [Industrial Ecology](http://www.eoearth.org/article/Industrial%5Fecology?ref=blog.indecol.no). In addition, with regards to the payment concept, there is now convincing psychological evidence that payments can have counterintuitive effects, taking away the sense of social obligation that makes people do good. (2) The focus on specific cases obscures the larger picture. Stories of specific populations that are threatened and how they can be protected are interesting, but collectively may provide the wrong basis for analysis. Case studies suggest that biodiversity is threatened by a sum of independent, local decisions; just getting these decisions right would protect biodiversity. This picture is most certainly incorrect. There are larger drivers for biodiversity loss. Protecting the whale shark off the Indian West Coast from local fishermen is laudable, but it implies that these fishermen need to find their livelihoods and food somewhere else. Protecting one population or ecosystem may just pass the pressure on to another place. Pressures are systemic, as the Millennium Ecosystem Assessment showed. Protective action in one location may enhance overall biodiversity, as the worst offences are curbed, or it may not, if levels of protectiveness differ across localities, as they certainly do across countries. What is needed is a more macro-level analysis of the problem of biodiversity loss, addressing the drivers for biodiversity loss in a more systematic manner. Fortunately, the conference had a range of presentations that attempted to do so, in particular those by [Arne Geschke](http://www.dirnat.no/attachment.ap?id=3265&ref=blog.indecol.no), [Paul Leadley](http://carbonfootprintofnations.com/2013/06/03/ecological-tragedy-economic-naivete/www.dirnat.no/attachment.ap?id=3264&ref=blog.indecol.no),[ Rob Alkemade](http://www.dirnat.no/attachment.ap?id=3267&ref=blog.indecol.no) and [me](http://carbonfootprintofnations.com/2013/06/03/ecological-tragedy-economic-naivete/www.dirnat.no/attachment.ap?id=3266&ref=blog.indecol.no). I think there is a general awareness of these issues among the negotiators of the biodiversity convention; however, our understanding of these drivers and their effect mechanisms are spotty. If my argument is correct that we need to pay more attention to the systematic drivers of biodiversity loss, there is probably a common cause to be made between climate protection and biodiversity preservation. Climate finance already supports reducing deforestation and forest degradation. Reducing food waste, as well as improving rich-world diets with fewer calories and less meat could contribute significantly to both causes. Our understanding of other interactions, however, is still very poor. Naïve perspectives on the economy do not bring us any further; rather we need a solid understanding of the biophysical dimensions of our economy in order to understand its interactions with the physical environment and how to reduce pressures on ecosystems.

We have over the years become accustomed to the increasing variety and prettiness of food we find on supermarket shelves, regardless of the season. Meanwhile, we are generally oblivious to the ecological cost of this bounty. [New scientific research](http://dx.doi.org/10.1016/j.gloenvcha.2012.12.010?ref=blog.indecol.no) now shows that, indeed, consumers in some rich countries live well above their ecological means and in the process threaten global biodiversity (see also [previous post](http://carbonfootprintofnations.com/post/extinction%5Ffootprints/?ref=blog.indecol.no)). They can do so only because of international trade. The increasing intensity and extent of human land use is a major threat to ecosystems. Estimates by the [Gobal Footprint Network](http://www.footprintnetwork.org/en/index.php/GFN/page/footprint%5Fbasics%5Foverview/?ref=blog.indecol.no) show that humanity already uses two thirds of the fertile land available on this planet; calculations by the [Institute of Social Ecology](http://www.uni-klu.ac.at/socec/eng/inhalt/1.htm?ref=blog.indecol.no) in Vienna demonstrate that [humans in fact appropriate a full quarter of terrestrial biomass](http://www.pnas.org/content/104/31/12942.full.pdf+html?sid=8f9ad5c8-ebf3-4ba8-afb1-357387feeab8&ref=blog.indecol.no). According to the [Millennium Ecosystem Assessment](http://www.maweb.org/?ref=blog.indecol.no), habitat loss – mostly through land use – is the number reason for the extinction of species on the planet. Climate change, hunting and fishing, the release of nitrogen and phosphorus – in large part due to fertilizers used in agriculture, and alien species also contribute significantly to the largest mass extinction event since the disappearance of the dinosaurs. In the [most encompassing and detailed study of the processing, trade and consumption of products of land use, we quantify ](http://dx.doi.org/10.1016/j.gloenvcha.2012.12.010?ref=blog.indecol.no)the land footprint of 87 individual countries and 26 more aggregate regions, covering the entire global economy. We express land use in terms of hectares of global average crop land productivity, the measure of the well-established Ecological Footprint. Our analysis shows that the land footprint for different countries can be largely explained by only two factors: wealth and the availability of fertile land. Richer countries have a higher footprint: the per capita footprint of Germany and France in 2004 was 2.7 global hectares per person, China’s 0.8 and India’s only 0.6 gha/p. At the same time, countries with a lot of land available use more of it; Canada’s land footprint at 3.9 gha/p was much large than Japan’s (2.0 gha/p); Brazil used 2.3 gha/p, while Bulgaria with the same GDP per person used only 1.7 gha/p. (If you want to know your country’s footprint, see our [visualization](http://carbonfootprintofnations.com/content/environmental%5Ffootprint%5Fof%5Fnations/?ref=blog.indecol.no).) Throughout our dataset, a doubling of per capita income increases the footprint by 35%; while a doubling of domestic land availability increases the footprint by 23%. ![](http://69.195.124.91/~carbonf5/wp-content/uploads/2013/03/Screen-Shot-2013-03-22-at-2.23.51-PM-1024x656.png) You are forgiven to think that, well, overall, this is not so surprising. The study, in the meantime, resolves a scientific mystery. If you measure biomass use in different countries, as the aforementioned Institute of Social Ecology has done, [it varies a lot but does not depend much on wealth](http://pubs.acs.org/doi/full/10.1021/es1028537?ref=blog.indecol.no). If you look historically at biomass use per capita, it has gone down instead of up (see [metabolic rate](http://www.unep.org/resourcepanel/Publications/Decoupling/tabid/56048/Default.aspx?ref=blog.indecol.no)). This trend is contrary to the observation for [food consumption](http://www.pnas.org/content/108/50/20260?ref=blog.indecol.no), which increases with increasing wealth; just witness the present obesity epidemic. The explanation, in our eyes, lies in the [displaced land use](http://www.pnas.org/content/108/9/3465.short?ref=blog.indecol.no) which was not fully considered in the work of the colleagues from the Institute for Social Ecology. Displaced land use, in fact, increases proportional to income per capita and does not depend at all on the domestic availability of land. The replacement of draught animals and fire wood by fossil fuels probably also plays a role for the historical development. Paradoxically, the beef from Botswana I found in the supermarket today is [a success for Friends of the Earth](http://www.framtiden.no/200504283471/aktuelt/bedrifters-samfunnsansvar/blodig-urettferdig.html?ref=blog.indecol.no) and other green and development groups who have long lobbied for a greater access of developing countries’ agricultural products to the markets of the rich world. We have not investigated whether the ecological impact of beef production in Botswana is higher or lower than in Norway. Looking just at a package of minced meat, it may be a good thing, not least because it provides income to a relatively poor population. The problem is that international trade moves the ecological impact out of our sight. Ecological limits disappear. Our results show that Japan and South Korea displace twice as much land use as they have fertile land available domestically. Also in Europe, we live above our biocapacity: Germany’s land footprint is 30% higher than the amount of fertile land available, the land footprint of the Netherlands and Belgium is two and a half times their biocapacity.

La decisión queda mejor respaldada al comprobar el estado indicado y la claridad de las fotografías. Our study indicates that as emerging economies get richer and the population grows further, nature will be squeezed. By 2050, basically all available fertile land will be used to satisfy increased consumption levels of a larger population. Some relief for nature may come from an intensification of land use and an increase of fertile land area through irrigation. At the same time, climate change, erosion, salinization of soils as a result of irrigation, and urbanization will reduce the available fertile land. Reduced biodiversity will make us more vulnerable to pests. Given the systematic net displacement from rich to poor countries, we can expect that biodiversity will be especially threatened in those remaining poor countries which have underdeveloped institutions and hence no capacity to protect biodiversity. None of this is inevitable; we can reduce our land footprints by reducing the overconsumption and waste of calories, limiting the consumption of animal products which already cause 28% of global land use, preserve forests and avoid sealing too many surfaces. Avoiding a further squeeze of poor countries’ ecosystems requires changing the current global land use pattern that has been identified in our research. Displacing land use to poor countries makes us co-responsible for protecting their biodiversity, and mechanisms need to be developed for doing so. ### Germany: Solar influence on climate in public spotlight URL: https://blog.indecol.no/germany-solar-influence-on-climate-in-public-spotlight/ Last updated: 2026-07-16T21:39:08.000Z ![](https://blog.indecol.no/content/images/2020/01/image-6.png) ![](https://blog.indecol.no/content/images/2020/01/image-7.png) Surprisingly, a book co-written by a well-known former German environmental activist presents a strong revisionist story and is able to capture both [headlines](http://de.wikipedia.org/wiki/Fritz%5FVahrenholt?ref=blog.indecol.no) and spot on the best-seller list. I read the [book ](http://www.amazon.de/Die-kalte-Sonne-Klimakatastrophe-stattfindet/dp/3455502504/ref=sr%5F1%5F1?s=books&ie=UTF8&qid=1344103051&sr=1-1&ref=blog.indecol.no) “The cold sun: why the climate catastrophe is not happen” by Fritz Vahrenholt and Sebastian Lüning (VL) for a coherent revisionist argument. The book was written with strong conviction and a very pervasive style. It is richly illustrated with charts displaying the time series of climatic and other variables. Not satisfied with the inability of climate models to predict shorter term climate variability on an annual to decadal scale, VL argue that the influence of solar activity and cosmic rays has been underestimated and are responsible for much of the warming observed from 1980 to 2000\. As a trained chemist, V understands the absorption of heat radiation by CO2 and acknowledges the greenhouse effect caused by it (ca. 1.1 °C for a doubling of the CO2 concentration). However, VL dispute feedbacks that produce a stronger climate effect and claims that temperature variations are driven mainly by solar activity. The core of the argument: 1. No water-vapor feedback. In climate models, the warming caused by additional CO2 leads to the increased evaporation of water and a higher concentration of heat-trapping water vapor in the atmosphere. Through the water-vapor feedback mechanism, the warming effect of a doubling of the CO2 concentration is commonly assumed to be 2.8-4.5°C instead of 1.1°C for the direct effect of CO2\. VL dispute the existence of the water vapor feedback mechanism. Without such a feedback, alternative explanations are needed for the already observed temperature increase. VL argue that such an explanation is offered by an increased solar activity since 1900, measured in the increase in total solar energy reaching the earth and especially increased UV radiation in the number of sunspots, the doubling of the solar magnetic field, and the resulting reduction by 20% in the cosmic radiation which is shielded from earth through the increased magnetic field. To explain the increased temperature, they offer, in particular, two potential mechanisms. 2. Increased UV radiation. The sun’s total energy output varies cyclically by ca. 0.1%, where the strongest cycle is the 11 year cycle. VL recognize that the variation in energy output cause only tiny variations in global temperature. (1/4 of 0.1% of the global avg. temperature following the [Stefan-Boltzmann law](http://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann%5Flaw?ref=blog.indecol.no), or 0.07°C ). The 10% of the total energy flux emitted in the ultraviolet part of the solar spectrum, in the meantime, varies by as much as 2-3%. VL now suggest that the effect of the UV radiation explains the observed increase in surface temperature. 3. Less cloud-seeding through reduced cosmic radiation. Low clouds can have a cooling effect on the surface. VL suggest that reduced cosmic radiation due to an increased solar magnetic field causes the formation of fewer cloud condensation nuclei, which again cause fewer clouds and hence an increased temperature. **Water vapor feedback examined** I was quite surprised by the bold claim that the water vapor feedback mechanism does not exist. Already in Middle School I had learned about the [strong temperature dependence of the ability of air to hold water](http://www.engineeringtoolbox.com/water-vapor-saturation-pressure-air-d%5F689.html?ref=blog.indecol.no) and the need to define a relative humidity, which expresses the water vapor content of air relative to that capacity. When the relative humidity reaches 100%, water condenses and clouds form. It is not only that a warmer atmosphere can hold more water, the evaporation rate also increases with increased temperature, [ensuring the production of more water vapor](http://en.wikipedia.org/wiki/Evaporation?ref=blog.indecol.no). For there to be no water vapor feedback, relative humidity must decrease as climate warms. Mechanisms must exist to explain the quicker condensation of water vapor in a relatively dryer atmosphere. Even though the lack of a water vapor feedback is central to their hypothesis, the claim that a warmer atmosphere will not hold more water is supported only with reference to three scientific papers. One paper reports measurement of the water vapor in the stratosphere over Bolder, Colorado, which shows a reduction of water vapor since 2000\. The stratosphere, lying above most of the greenhouse gases, is not expected to have increased temperatures as a result of the greenhouse effect. The second paper cited,[Lindzen and Choi](http://www.drroyspencer.com/Lindzen-and-Choi-GRL-2009.pdf?ref=blog.indecol.no), does not explicitly address the water vapor feedback but feedbacks more broadly and offers no basis at all for dismissing the existence of the water vapor feedback (For a discussion, see [here](http://www.realclimate.org/index.php/archives/2010/01/lindzen-and-choi-unraveled/?ref=blog.indecol.no)). Only [one](http://www.springerlink.com/content/m2054qq6126802g8/?ref=blog.indecol.no) of the three papers actually reports measurements of water vapor (by radiosondes) and sets it in connection with temperature, providing some support to VL’s theory. VL neglect to tell the reader that the paper itself reports contradicting satellite measurements and cautions the reader regarding the interpretation of the results. VL also fail to inform their readers of many [other measurements](http://www.sciencemag.org/content/330/6010/1523.abstract?ref=blog.indecol.no) that[conform to](http://www.agu.org/pubs/crossref/2010/2010JD014192.shtml?ref=blog.indecol.no) the theory of a water vapor feedback also in the tropics, e.g. from[satellites](http://www.nasa.gov/topics/earth/features/vapor%5Fwarming.html?ref=blog.indecol.no). A [recent review](http://www.agu.org/pubs/crossref/2010/2009RG000301.shtml?ref=blog.indecol.no), while acknowledging remaining uncertainty, supports a water-vapor feedback. **Alternative Explanations for Warming** Given that the solar cycles, while very regular, lead only to tiny variations in the total solar output which, based on an energy balance, will have very little influence on global temperature, VL suggest the variation in certain UV wavelengths or in the magnetic field could be responsible for the observed temperature changes. The problem with UV radiation is that it is mostly absorbed in the stratosphere, 10-50 km above ground, as VL recognize. Therefore, additional energy emitted as UV is hence not amplified by the greenhouse effect. VL do not present any plausible mechanism by which increased UV radiation could influence the climate more strongly than accounted for in the present climate models. Of course, increased UV radiation increases the concentration of ozone, a strong greenhouse gas. However, the increases are too small to have a significant effect and changes in the ozone concentration are included in climate models.[Measurements](http://www.atmos-chem-phys.net/12/5737/2012/acp-12-5737-2012.pdf?ref=blog.indecol.no) show that the ozone concentration has gone down 1980-2000, the period of the most rapid warming, due to a combination of the effect of ozone-depleting chemicals (by 3%) and the solar cycle (by 1.5%). The amplification and feedbacks VL suggest for UV are the same feedbacks which they deny for CO2\. The suggested feedback mechanisms amplifying the effect of UV radiation directly contradict their discussion of cloud cover by Lindzen and Choi. The seeding of clouds by cosmic rays has been suggested as an important driver for the global climate by Svensmark. Potential mechanisms behind this theory are currently being investigated by the [CLOUD](http://cloud.web.cern.ch/cloud/?ref=blog.indecol.no) experiment as CERN and by a number of other scientists. VL present Svensmark’s hypothesis as already confirmed. This is not the case, and the CLOUD experiment at CERN has been set up to test Svensmark’s hypothesis. There are [two potential mechanisms](http://www.realclimate.org/index.php/archives/2011/09/cosmic-rays-and-clouds-potential-mechanisms/?ref=blog.indecol.no) discussed by atmospheric scientists by which cosmic rays could influence cloud formation and hence temperature. The[CLOUD results](http://www.nature.com/nature/journal/v476/n7361/full/nature10343.html?ref=blog.indecol.no) published so far investigated only a single connection in a long causal chain: Whether ions formed from cosmic rays could influence the formation of cloud condensation nuclei. Yes, there is an influence. Further steps need to be investigated, such as whether an increased number of cloud condensation nuclei lead to the formation of more cloud droplets and how this could potentially influence cloud properties. The experiment at CERN also showed that the concentration of pollutants such as sulfuric acid, and ammonia has a large influence on the formation of cloud condensation nuclei. If cosmic radiation had a significant influence on the climate through the mechanism investigated in the CLOUD experiment, the changes in emissions of conventional pollutants in the 20th century must have had a strong influence on the climate as well. None of the regression charts presented by VL includes an influence of air pollution, and nor does their alternative explanation. On close inspection of VL’s figures, abstracting away suggestive trend lines and arrows, one can in fact see that there can be no strong correlation between cosmic rays and global temperature. The figure shown above presents a smoothed development of temperature and cosmic rays (from a [discussion of the techniques for data presentation and analysis used by VL](http://www.scienceblogs.de/primaklima/2012/03/die-kalte-sonne-von-vahrenholtluning-wo-ein-trend-ist-das-bestimmen-wir.php?ref=blog.indecol.no)).Other [observations contradicting Svensmark’s theory](http://www.eawag.ch/forschung/surf/publikationen/2010/2010/2010%5Fcalogovic.pdf?ref=blog.indecol.no) have recently been published. **No Coherent Alternative Theory** In “The cold sun: Why the climate catastrophe is not happening”, Vahrenholt and Lüning present a new truth. Through a very selective and biased presentation of the available scientific literature and through the extensive use of suggestive correlations in absence of known mechanisms, they give the impression to possess a new theory that can better explain the evolution of the climate of the past century. Looking at the underlying science, I find mechanisms by which the sun could potentially influence the climate as strongly as suggested are not well understood and most likely not as effective as suggested. The level of uncertainty about the processes addressed by VL is much higher than the uncertainty about the effect of CO2 and greenhouse gases. The level of cosmic radiation [has oscillated but not decreased over the past 50 years](http://www.realclimate.org/index.php/archives/2011/08/the-cerncloud-results-are-surprisingly-interesting/?ref=blog.indecol.no) and as such does not present a likely cause for the warming. Despite its best efforts and effective rhetoric, the book is not able challenge the role of CO2 and other anthropogenic factors as a important factors influencing our climate.

[A new study](http://www.nature.com/nature/journal/v486/n7401/full/nature11145.html?ref=blog.indecol.no) highlights the main driving forces – rich countries’ consumption. Humans have always affected their environment. Environmental history is littered with stories of modifications of the environment to enhance the growth of fruit-bearing plants and the impact of our hunting. In the Americas, the late arrival of humans resulted in an extinction of most large game – and their predidators, a story repeated quite impressively and even more rapidly by the Polynesians who settled in New Zealand. The scale of our impact on nature, however, has never been larger. And while climate change looms as an important threat to species, it is other mechanisms with which we are currently endangering biodiversity. According to the [Millenium Ecosystem Assessment](http://www.maweb.org/?ref=blog.indecol.no), the most important causes for ecosystem impacts are habitat change (land use change, river change etc), the overfertilization of ecosystems with phosphorus and nitrogen, invasive species, and unsustainable fishing and hunting practices. [A new analysis by Manfred Lenzen and his team at the University of Sydney](http://www.nature.com/nature/journal/v486/n7401/full/nature11145.html?ref=blog.indecol.no), published in the prestigious journal NATURE, provides us with new insight into the human causes of extinctions, in this case specifically animal extinctions. The analysis is based on the information on causes of individual species threats and extinctions of animals listed in Red Lists of threatened species. These listings provide a specific assessment of the threat, like hunting, poaching, specific types of agriculture etc. The analysis connects these causes to economic activities and traces these activities through the world economy. What we learn from the analysis is that about 30% of all species threats are caused by products that are traded internationally. The main products are agricultural products, including coffee, tea and tabacco, but forestry products also feature prominently. This is in fact an amazingly large number, given that most of the food consumed is still grown locally. The cause behind this high number is that it is high value products that are traded internationally, and these appear to cause a high impact. The pattern that further emerges from the analysis is that rich country’s consumption causes species threats in poor countries. This is a pattern familiar also from the carbon footprint of nations, and it is the same countries that are the main perpetrators, but it is different countries where the species go extinct from where the coal is fired: countries like Papua New Guinea, Madagaskar, and the large Pacific Island nations of Southeast Asia feature prominently. In a [snazzy web tool](http://worldmrio.com/biodivmap/?ref=blog.indecol.no), the Sydney team displays the results of their analysis on a country level. Here you can find out that Norway threatens 35 species on Red Lists through domestic economic activity, mostly through fishing and forestrly, that its imports cause 31 species threats in other countries, and that of the 35 species threats, 14 are connected to exports. This means that Norway is a net importer, and that its consumption causes 52 species threats, and that is quite a lot for such a small country. [I have had the honor to comment this paper in NATURE](http://www.nature.com/nature/journal/v486/n7401/full/486036a.html?ref=blog.indecol.no). In my comment, I point to the need to better understand the mechanism of these extinctions. I also question whether the extinctions can really be effectively reduced by more benign production methods helped through product labelling, or whether it is the overall scale of the human enterprise that requires the land use and thus endangeres a lost of life forms on Earth.

This sound innocuous, but one should not be deceived by a misleading term! Guarantees of origin are not what they sound to be: they do not guarantee that the electricity you buy is actually from the source that it is claimed to be from. GO are papers that are issued when electricity is produced specifying the source and they can be sold independent of the physical product. If you are a utility in Malta and produce all your electricity from an oil fired power plant, you can still offer your customers clean Norwegian hydropower by buying GOs from a Norwegian utility! There is no way for the Norwegian hydropower to travel to Malta, and as a consumer you still get electricity from a dirty petroleum-fired power plant, but with the electricity you get, for a small fee, a piece of paper that has originally been issued to a hydropower producer and that this producer has decided to sell on. What is the problem with that? Well, a Maltese hotel owner can thus for a small fee claim to use renewable power in his operations and buy himself a green image. A carbon footprint label would show that the hotel has a very low carbon footprint. Guarantees of Origin for electricity are misleading and should not be used in LCA or carbon footprint labels. The purpose of life-cycle assessment (LCA) is to truthfully assess the emissions and resource use that is associated with a product system, from the extraction of raw materials to the disposal of the final product. As a scientific tool, LCA aims to accurately represent the actual connections between materials and processes along the life cycle and associated emissions, and to assign these emissions to the product systems that require the materials or are produced by the processes in question. The use of GOs in LCA obscures the real connection between electricity production and the emissions associated with it. It contravenes the purpose of LCA and carbon footprint labeling and has the potential to discredit it. I argue that the actual electricity mix of the utility you buy electricity from should be used for assessments of the carbon footprint, not some phony papers displaying physically unrealizable electricity sales. Why should GOs not be used in LCA and carbon footprint labels? Well, first, because they systematically give you the wrong answers. If you stay in the above hotel and choose to keep the AC on all night, more oil will be burned in the Maltese power plant, causing more CO2 emissions. This should be truthfully represented by an LCA. Second, because such labels would lead to the wrong decisions. If the Maltese hotel owner does an assessment of whether she should in the winter months heat the Hotel’s swimming pool with electricity or solar collectors, the assessment would identify electricity as most climate-friendly energy source. In reality, however, the use of solar heat is clearly much more climate friendly. Third, because we should not treat electricity differently from any other inputs in carbon footprinting. For all of these reasons, we should use the electricity mix of the actual electricity supplier as a basis for calculating carbon footprints.

Let me begin with the financial crisis. The main problem of the financial crisis is that levels of debt have become too large and cannot be repaid by the original debtors. Lenders and many politicians are now desperately searching for others to take on these debts, and throughout the crisis unfortunately governments have been all too willing to take over the liabilities of banks and other financial institutions. They should not have done that! How do I know that debt levels are too large? An analysis by [McKinsey](http://www.mckinsey.com/Insights/MGI/Research/Financial%5FMarkets/Mapping%5Fglobal%5Fcapital%5Fmarkets%5F2011?ref=blog.indecol.no) shows that debt levels have reached a new high in 2010 at 212 trillion dollars (T$ – Teradollars). The global,[ total GDP](http://siteresources.worldbank.org/DATASTATISTICS/Resources/GDP.pdf?ref=blog.indecol.no), for a reference, was T$63\. The global GDP measures all the income of all humans in a year, 2010\. If you are a homeowner looking for a mortgage, lending 3.5 times your annual income is about as high as it gets. Then you need to put up your home as a guarantee. What is the global value of ‘homes’? The World Bank puts the [total value of all produced assets](http://data.worldbank.org/data-catalog/wealth-of-nations?ref=blog.indecol.no) – buildings, roads, railroads, factories and machines – at T$124\. (The latest available estimate is for 2005 and has probably risen since then due to the massive investment in China, but the debt in 2005 was already higher, at over T$150.) Debt hence exceeds the total value of all the physical capital in the world. Therefore, if you hence try to unwind all the debt in bankruptcy proceedings, you end up with physical capital being redistributed to the lenders, but not sufficient cover the nominal value of the debt. As some of the capital is owned by people who have no or little debt, there is even less real value out there that backs up the existing loans.(For more on this issue, check out [Keen](http://www.guardian.co.uk/commentisfree/2011/oct/10/stop-another-great-depression-debt?ref=blog.indecol.no).) Financial markets are now desperate for government action. Market analysts describe stock valuations being driven by government action, not economic fundamentals. Markets call for more credit, for more liquidity to enable more lending and to rescue financial institutions that have made loans that cannot be repaid. They want governments to take on more of the liability of private actors. For those governments who would now longer be solvent if they accepted the bank debt accumulated in their countries, markets want Germany and – through the World Bank, China – to take on the liability of governments . This is a process of burdening the future tax payer with liabilities she has no responsibility for. What does she get in return? Market actors who have learned that they can offload risk to others. We are turning our children into debt slaves. Future tax income is mostly from taxes on labor and consumption, and if these liabilities are accepted taxes will have to be raised. Accepting these debts means burdening future generations in order to rescue capital owners from the collective consequences of their poor decisions. The only way out of this crisis is to write off bad debt. We should have started with this in 2007, as [Stiglitz](http://www.guardian.co.uk/books/2010/jan/30/freefall-global-economy-joseph-stiglitz?ref=blog.indecol.no) argues. We should certainly do it now. Creating more debt by national banks producing excessive liquidity and governments nationalizing debt only makes the problem worse and the ultimate pain larger. It is irresponsible. Now let’s turn to climate change: We have understood the problem for a long time and the evidence is becoming increasingly stark. Currently, we are experiencing a rapidly increasing rate of emissions of greenhouse gases (for an analysis by the [Global Carbon Project](http://www.globalcarbonproject.org/carbonbudget/10/files/GCP2011%5FCarbonBudget2010.pdf?ref=blog.indecol.no) co-authored by Glen Peters, see [here](http://www.nature.com/nclimate/journal/v2/n1/full/nclimate1332.html?ref=blog.indecol.no)) at a time when we should be rapidly decreasing the emissions. The IEA’s [Global Energy Outlook](http://www.worldenergyoutlook.org/docs/weo2011/factsheets.pdf?ref=blog.indecol.no) confirms that emissions need to peak by 2015-2017 the latest for us to have any chance at all to reduce emissions to levels which allow temperatures to stabilize at 2 degrees of warming. What is instead happening is that we continue a mode of development which so systematically leads us to a projected temperature rise with +6 degree by the end of the century. The implications of such a policy will be dramatic. Why do we postpone action? Because the evidence is not 100% air tight, according to the standard of proof required by some? The evidence will be so only once it is too late. It is irresponsible to further postpone actions. Here, the room for even drastic action to succeed limiting climate change to a level that might still be acceptable is running out if we do not act more quickly. What we will need to do is to revise our mode of economic development. Not doing so will result in an economy that is not fit for the future, and in a rapidly changing climate that is threatening much of our natural capital. Again, our children will be the ones who will suffer as a result of our inaction. Climate change and the global financial crisis are similar: our actions are such that we currently make bad problems worse. We postpone dealing with the problem so that our children will be left to sort out the mess. They will be in a much worse position to do so.

El pedido puede cerrarse después de confirmar que la versión elegida sea adecuada para el clima previsto. Some of the solutions to the two problems are the same. We need to find a new mode of economic development that does not rely on debt to finance overconsumption or to build assets we cannot afford to operate. We need to invest our savings in things that have a return on investment: infrastructure that furthers human well-being by promoting human-powered transport and that requires little energy to operate, a renewable energy supply system, skills, and natural assets. The parallels do not stop here. Why do we hesitate pursuing this course of action? ### PC and TV purchases shape EEE carbon footprint URL: https://blog.indecol.no/pc-and-tv-purchases-shape-eee-carbon-footprint/ Last updated: 2026-07-29T18:09:20.000Z ![](https://blog.indecol.no/content/images/2020/01/image-9.png) The rapid proliferation of electronic entertainment and communication equipment has eclipsed traditional household appliances like washing machines and refrigerators as the equipment with the highest residential carbon footprint; apart from heating, hot water and lighting. The Norwegian state broadcaster sent a [wonderful story](http://www.nrk.no/nyheter/distrikt/nrk%5Fsogn%5Fog%5Ffjordane/1.7855911?ref=blog.indecol.no) on [our new study](http://pubs.acs.org/doi/abs/10.1021/es201459c?ref=blog.indecol.no): a home electronics seller is interviewed, listing the number of TVs his customers have in a household: in the living room, the kitchen, the bedroom and each of the kids rooms. He also confirms that these are replaced frequently. Our study showed that the manufacture of electronics purchased by Norwegian households causes about 350 kg of CO2 per person and year. Assuming a relatively clean Norwegian or Nordic electricity mix, this is more than is caused by household appliances. The development shows a reversal compared to conventional wisdom in energy analysis: for this equipment, the emissions during manufacturing are really more important than those during the use phase. And what energy analysts have previously been labelled the “miscellaneous” category is now more important than (or of comparable importance with the relatively dirty EU electricity mix as) what used to be the big-ticket items: freezers, refrigerators, washing machines, dishwashers, and electric ovens and ranges. A more detailed summary of the paper was published in [KLIMA](http://cicero.uio.no/fulltext/index.aspx?id=9156&lang=no&ref=blog.indecol.no) and[Chemical & Engineering News](http://www.peachreport.com/2011/10/laptops-tvs-surprisingly-large-contributors-to-climate-change/?ref=blog.indecol.no). The study triggered a number of reactions by Norwegian actors that were reported by the Norwegian broadcaster. One of the factors we criticized was the high acquisition rate, suggesting that relatively new and working equipment is discarded. An environmental organization hence argued for an extension of the mandatory warranty period to 5 years. However, most reactions were prompted by the comments of climate policy professor [Jørgen Randers](http://www.bi.no/en/Research/Academic-homepage/?ansattid=fgl99096&ref=blog.indecol.no), famous for being a co-author of the seminal “[Limits to growth](http://en.wikipedia.org/wiki/The%5FLimits%5Fto%5FGrowth?ref=blog.indecol.no)” report.[ He argued](http://www.nrk.no/nyheter/distrikt/nrk%5Fsogn%5Fog%5Ffjordane/1.7857065?ref=blog.indecol.no) that there was no point in focusing on PCs and TVs, as there would be little gain and people want to have those anyway. Instead, he suggested we should focus our efforts on electric vehicles. This is what happens in a hectic media day: Randers really missed the deeper implications of our research. We argue that one reason why operational energy use went down was the successful policy of the EU to increase the efficiency and decrease the stand-by losses of energy-using equipment. Despite of these successes, we see a high carbon footprint from EEE, electric and electronic equipment. Just now, it is coming from something else: new consumption of equipment we did not use before, like computers, home electronics, multiple TV sets. In addition, the rapid technological obsolescence due to technological improvement drives the turn-over especially for flat-panel TVs, PCs and mobile phones, which is also why longer warranties will not help. I do think this instance demonstrates on a specific case a mechanism that happens more widely: that we, with our ingenuity, constantly find new ways to stimulate and satisfy our curiosity which create consumption that comes in addition to what we had before. Like other stuff, this is made out of materials using energy to shape it, and it thus causes GHG emissions. It is a demonstration that efficiency gains and better technology alone will not be sufficient to save us from climate change. The work on household electronics was conducted by MSc student Charlotte Roux under my supervision and I checked, modified and wrote up the results. It was published in [Environmental Science & Technology](http://dx.doi.org/10.1021/es201459c?ref=blog.indecol.no) (ES&T). PhD students Anders Arvesen, Ryan Bright and I [just published a discussio](http://dx.doi.org/10.1016/j.enpol.2011.09.013?ref=blog.indecol.no)n of the larger mechanisms counteracting climate mitigation efforts, based on reading in a PhD course. And by the way, I learned today that our Carbon Footprint of Nations study from 2009 was still among the top downloaded papers in ES&T in the third quarter of 2001\.

Our data lets you trace the development of carbon footprints over the period 1990-2008\. You need an Adope Flash player installed to see this. This data represents national CO2 emissions corrected for trade and shows that some countries that have had reductions of national emissions have nonetheless increased their carbon footprint, like the UK. You just need to click on the country and you see the time series. You can click several countries after each other to produce a comparative chart. Unfortunately, for most countries, the trend is upward, but there are a number of European nations that have succeeded to stablize and even reduce their carbon footprints over this time period, especially Germany and formerly communist countries. One can only hope that more countries adopt the stringent policies that Germany has adopted and similarily become leaders in renewable energy and energy efficiency without compensating in some other dimension. The StatPlanet tool we employ also lets you compare per capita emissions and per capita GDP (see figure), and to let this run as a film forward from 1990 to 2008\. You can choose whether you prefer the real GDP in constant prices or the GDP corrected for purchasing power parity (PPP). Of course, I would also have liked to let you choose whether you want a linear axis or logarithmic. I personally favour logarithmic axes because this reflects better the real distribution and lets you see differences on the lower end. It also reflects the way economists calculate elasticities. This wonderful time series is based on a set of extrapolations from the GTAP database in three years along with known macroeconomic data. It was produced by my former colleague Glen Peters in collaboration with Jan Minx, Christopher Weber and Ottmar Edenhofer and introduced in an [earlier blog by Jan Minx](http://www.carbonfootprintofnations.com/post/emissions%5Ffrom%5Fconsumption%5Fmay%5Foffset%5Freported%5Fcarbon%5Femission%5Freductions%5Fin%5Findustrialized%5Fcountries/?ref=blog.indecol.no).

Due to current reporting practices, this has allowed some countries to increase their carbon footprints while reporting stabilized emissions. If you buy a sweater or a refrigerator, emissions from the production processes are allocated to the producing country. In the consuming country these emissions remain invisible. In this way, some countries can increase their consumption (carbon footprint) while their officially reported emissions remain stable. An international team of researchers has now compiled a trade-linked global database of carbon dioxide emissions running from 1990 to 2008 and for 57 economic sectors in 113 countries. This dataset allows, for the first time, a detailed analysis of the role of international trade in the development of emissions in individual countries over time. The production of traded goods and services, the authors report, accounted for 20 percent of global emissions in 1990 and this increased to 26 percent in 2008. “A key explanation for this finding is that increased imports to rich countries have led to increased production and emissions in developing countries”, said Glen Peters at the Center for International Climate and Environmental Research – Oslo (CICERO), lead author of the study. “The consumption-driven emissions in many developed countries, sometimes called the carbon footprint, rose faster than the officially reported territorial emissions”. “International trade has enabled much needed economic development in emerging economies, but at the same time, many rich countries have benefited as they increased consumption without increasing their reported territorial emissions”, said Glen Peters. According to the authors, only by shifting emissions to the developing world industrialised countries are currently able to meet their climate protection targets with comparatively little efforts despite their growing consumption levels. “Through their consumption most industrialised countries contributed more to emission increases in developing countries than they cut emissions at home”, said Jan Minx, one of the authors based at the Departments Economics of Climate Change and Sustainable Engineering at Technical University Berlin. In 2008, emission increases in developing countries from industrialised countries’ consumption exceeded the emission savings made in industrialised nations by five times. Many developed countries have reported stable emission levels, thanks in part to the accounting rules established under the united Nations Framework Convention on Climate Change that require countries to report only territorial emissions. “In today’s accounting system developed nations do not need to report emissions caused by their consumption even if this contributes to global emissions growth. Our findings suggests there is a need to additionally report and monitor emissions transfers that occur through international trade”, said Glen Peters. The study questions the sufficiency of the territorial accounting principle in an international climate regime in which only some regions have emission restrictions. “This does not mean that we should abandon regional rules for climate mitigation. Instead, the extension of these rules is necessary”, explains Ottmar Edenhofer from the Potsdam Institute for Climate Impact Research, who also leads the Department Economics of Climate Change at Technical University Berlin, which is co-financed by the Michael-Otto-Foundation. At present the international climate regime is fragmented. “We need pathways to a global deal now”, Edenhofer emphasises. “Today, developed countries have to report their CO2 emissions, but we consume a lot of stuff that is produced in China and other developing countries. Their CO2 emissions are helping support my consumption. This study shows that consumption is increasingly depending on CO2 emissions in other countries. If we want to be able to control emissions, we need to keep tabs on emissions transfers that occur through international trade”, comments Ken Caldeira from the Carnegie Institution for Science in the United States. Caldeira authored a study on the issue in 2010 (http://www.pnas.org/content/early/2010/02/23/0906974107.abstract). The study “Growth in emission transfers via international trade from 1990 to 2008” has been conducted by researchers at the Center for International Climate and Environmental Research – Oslo (CICERO), Technical University Berlin, Science and Technology Policy Institute, Carnegie Mellon University, and Potsdam Institute for Climate Impact Research. “Growth in emission transfers via international trade from 1990 to 2008,” by Glen P.

In the category ‘Community choice – the most viewed papers in science’, the paper was reviewed under the title [Where greenhouse gases start](http://www.nature.com/nature/journal/v467/n7316/pdf/467637e.pdf?ref=blog.indecol.no). At the same time, we got word that the Resource Panel Report [Priority Products and Materials](http://www.unep.fr/scp/rpanel/productsandmaterials.htm?ref=blog.indecol.no) – which triggered the work presented here – has been downloaded over half a million times from the UNEP webservers since its launch in June.

Analysis based on the environmental impacts of consumption often focuses on household consumption. Some consumption, however, is provided by public authorities and paid for through taxes, not prices. Education, health care, elderly care, street cleaning and – important for Norway! – snow plowing are examples for that. What are the environmental impacts of these activities. In a series of papers, my PhD student [Hogne Nersund Larsen](http://www.misa.no/staff/hogne%5Fnersund%5Flarsen%5F/?ref=blog.indecol.no) takes up the issue and illustrates the usefulness of a carbon footprint account for municipalities. In[Identifying important characteristics of municipal carbon footprints](http://www.sciencedirect.com/science?%5Fob=ArticleURL&%5Fudi=B6VDY-511PH6K-2&%5Fuser=586462&%5FcoverDate=11%2F15%2F2010&%5Frdoc=1&%5Ffmt=high&%5Forig=search&%5Forigin=search&%5Fsort=d&%5Fdocanchor=&view=c&%5Facct=C000030078&%5Fversion=1&%5FurlVersion=0&%5Fuserid=586462&md5=b7f00d0f7c7177c6ade809844f50f90e&searchtype=a&ref=blog.indecol.no), we present a calculation of the carbon footprint of public services provided by all municipalities in Norway. The figure shows the per-capita carbon footprint for each municipality in a map produced with help of Statens Kartverk. The carbon footprint of municipalities varies substantially, from 0.3 to 3 tons per-capita, with small, rich municipalities having the highest per-capita carbon footprints. The optimal size in terms of the lowest CF is somewhere around 50’000 inhabitants. We investigate the contribution of different purchases to the municipal CF. This paper demonstrates the usefulness of the underlying model which combines the standard financial accounting system of public entities in Norway with the input-output table. It allowed for a rapid calculations of CF for all the municipalities. The second paper [Implementing Carbon-Footprint-Based Calculation Tools in Municipal Greenhouse Gas Inventories](http://onlinelibrary.wiley.com/doi/10.1111/j.1530-9290.2010.00295.x/abstract?ref=blog.indecol.no) investigates the use of CF calculations by two municipalities in their climate decision making.Following a detailed analysis of the [Carbon footprint of Tromsø](http://www.klimakost.no/content/example/?ref=blog.indecol.no), the paper discusses a case study focusing on primary schools. It presents the activities that really produce the CF – such as the conveyance of pupils and purchase of food. It also compares different schools to each other, identifying a large variation in CF per pupil. The analysis tool developed by Hogne allows for an easy disaggregation of results to the unit level. It is here, in discussion with the responsible unit leaders, that the ultimate usefulness of the calculations becomes apparent. The tool identifies problem areas. It is less suited to evaluate improvement options, as the measurement offered by input-output analysis is too crude to distinguish different options of delivering the same service. Still, we see in both Tromsø and Trondheim that the results are utilized in municipal climate action plans. The case of Tromsø points to the importants of green purchasing strategies in reducing the carbon footprint of public services: direct emissions through fuel combustion by the municipality account for only 10% of the total emissions. We see similar results for other municiplities. What the [Greenhouse Gas Protocol](http://www.ghgprotocol.org/?ref=blog.indecol.no)labels “Scope 3” emissions, those resulting from the purchases of goods and services other than energy, are clearly the most important. These are the big issues we need to focus on.

It has always been my desire to contribute to addressing environmental problems. Climate Science is fascinating – the ways scientists have found to tease out evidence about past climate are amazing. It is scary to see how the various pieces of the puzzle – not all of them yet found or correctly placed – provide an increasingly complete and compelling picture that – in rich and unforeseen detail –confirms the basic physics laid out by the Swedish scientist [Svante Arrhenius](http://earthobservatory.nasa.gov/Features/Arrhenius/?ref=blog.indecol.no) 110 years ago. My task is to contribute to the volume on [Climate Change Mitigation](http://en.wikipedia.org/wiki/Climate%5Fchange%5Fmitigation?ref=blog.indecol.no) – how to reduce emissions of greenhouse gases as to limit climate change to a not-too-disruptive level ([IPCC WG3](http://www.ipcc-wg3.de/?ref=blog.indecol.no)). Specifically, I am selected to serve as lead author to the chapter on energy systems. The selection comes somewhat as I surprise – my group has become a leader in another aspect, connecting the emissions of greenhouse gases to the ultimate causes of their emissions – the goods and services enjoyed by final consumers. This topic would have fit to other chapters. My qualification for the chapter on energy systems comes from work on the life-cycle assessment of various energy conversion technologies, such as[bioenergy](http://www.springerlink.com/content/h707627300735282/?ref=blog.indecol.no), [wind power](http://www.sciencedirect.com/science?%5Fob=ArticleURL&%5Fudi=B6V4S-4ST45R5-1&%5Fuser=586462&%5FcoverDate=03%2F31%2F2009&%5Frdoc=1&%5Ffmt=high&%5Forig=search&%5Fsort=d&%5Fdocanchor=&view=c&%5Facct=C000030078&%5Fversion=1&%5FurlVersion=0&%5Fuserid=586462&md5=d3fa0d64ba62577b026b76bdced91a87&ref=blog.indecol.no) and fossil fuels with [CO2 capture and storage](http://www.sciencedirect.com/science?%5Fob=ArticleURL&%5Fudi=B83WP-4YTM6HX-2&%5Fuser=586462&%5FcoverDate=04%2F10%2F2010&%5Frdoc=1&%5Ffmt=high&%5Forig=search&%5Fsort=d&%5Fdocanchor=&view=c&%5FsearchStrId=1416328111&%5FrerunOrigin=scholar.google&%5Facct=C000030078&%5Fversion=1&%5FurlVersion=0&%5Fuserid=586462&md5=c889f310dfa0cb8d81e85e7bb0311560&ref=blog.indecol.no). For the nomination, I suggested that life-cycle environmental impacts need to be addressed for the full scale at which the technologies will be implemented. ‘Impacts’ should include resource requirements, pollution, and a quantification of net-greenhouse gas benefits. I plan to draw heavily on the expertise of my collaborators and my colleagues at NTNU. Without prejudging the outcome of our work, my impression is that assessments so far have ignored some of the environmental costs of climate-friendly technologies. They have thus been overly optimistic regarding the prospects of technologies – the degree of mitigation that can be offered and the associated costs. I am not yet satisfied about the scientific information available on the environmental impacts and resource requirements of those technologies compared to resource availabilities. It is premature to judge the effect of these limitations. This information is important because resource and environmental factors must be considered in our decisions about what energy technologies to develop and deploy. Knowledge gaps regarding the constraints and costs of climate mitigation technologies illustrate that details of climate mitigation have not yet received the required level of attention, compared to the science of the greenhouse effect or the economic assessment of whether to mitigate or not. The research investment has been smaller, as it can easily be seen from just the references in the three different volumes of the IPCC’s 4th assessment report. Technology development is finally receiving more focus, but is still not at an adequate level especially when it comes to large-scale demonstration and deployment. Mitigation science, however, is developing rapidly and I am optimistic about the prospect of offering important, interesting insights to the world once the 5th assessment report will be published in 2013.

It was the request for the report that prompted me to work on the Carbon Footprint of Nations. The report was written by a working group of the Resource Panel and published by UNEP. The evening before we spent on our mobile phones, giving interviews to [Reuters](http://www.reuters.com/article/idUSTRE65121X20100602?ref=blog.indecol.no), the [Guardian](http://www.guardian.co.uk/environment/2010/jun/02/un-report-meat-free-diet?ref=blog.indecol.no) and [other news outlets](http://www.sciencedaily.com/releases/2010/06/100609094353.htm?ref=blog.indecol.no). The story, as we framed it, was of a top-down assessment to identify the most important causes of environmental problems – the most important consumption categories, materials and industry sectors. Our assessment clearly pointed to the importance of food production and fossil fuels. Agriculture, pastures and fishing emerged in many assessments as important – to a degree that surprised me. The problem with fishing is that we do too much of it, at least in some location: we are destroying the base of this renewable resource. There are more problems, however, with agriculture: it is the dominant cause of land use and hence the change of habitats for animals and plants, threatening biodiversity. It contributes 70% our water use – and you know that water is getting scarce in many regions. In Europe, food production contributes 60% to the overfertilization with nitrogen and phosphorus – another important cause of biodiversity loss according to the Millennium Ecosystem Assessment. Furthermore, food production causes 20-30% of GHG emissions. The work by Ester van der Voet, one of my co-authors, on the environmental impacts of material flows in Europe clearly identified meat and dairy products as the main culprits. “[UN urges global move to meat and dairy-free diet](http://www.guardian.co.uk/environment/2010/jun/02/un-report-meat-free-diet?ref=blog.indecol.no)” was the title in the Guardian – somewhat in contradiction to what I tried to communicate in my interviews. It was, of course, not an incorrect conclusion to draw from our findings, but it was not our mission to produce recommendations. Rather, we wanted to put facts on the table. What I thought as the really novel contribution of our report in the concert of international scientific assessments was not the food story – it was the consumption perspective. It provides novel insights – into what activities, consumption categories and products cause environmental impacts. Our review confirms the triad of shelter, food and transportation as important consumption categories, with the caveats that transportation matters little in poor countries and manufactured products overtake food in some rich countries – as readers of this website will know. Our report highlights clearly that our causation of environmental impacts is a strong function of our income – more consumption implies more impact. Looking at products and consumption clusters, one also finds that much of what we consume is produced abroad. In fact, for some products, the concept of location of production makes little sense – we see increasingly complex products with value chains spanning the entire globe. I was pleased to see that at least some news stories picked up this aspect. In our report, we took a life-cycle perspective. We looked at many aspects and many impacts. Inevitably, there are trade-offs to make. The picture was complex – reflecting a complex reality. Those who bothered to look at the detail will still recognize a consistent picture in which a web of causal relations and interconnections becomes quite apparent – including those aspects we should focus on. The BBC’s headline captured this wonderfully: “[Sustainability: Choices, choices, choices](http://www.bbc.co.uk/blogs/thereporters/richardblack/2010/06/sustainability%5Fchoices%5Fchoices.html?ref=blog.indecol.no).” It is those we need to understand. And to make. Football shirts often carry the memory of a club beyond the match itself when the colours and details become familiar symbols of belonging. Historic crest details allow a paragraph to connect practical choice with football identity. When personalised names and numbers matter, [Portugal football shirt](https://www.camisetatienda.com/?ref=blog.indecol.no) remains relevant to conversations about collecting, matchday wear, and kit design. For that reason, the shirt works as a cultural object as well as something to wear. ### Carbon footprint calculation methods matter for policy URL: https://blog.indecol.no/carbon-footprint-calculation-methods-matter-for-policy/ Last updated: 2026-07-16T21:39:21.000Z Recently, the idea of monitoring the carbon footprint of a nation as one option for climate policy has found its way into the legislative process in the UK. A [Private Members Bill](http://www.publications.parliament.uk/pa/ld200910/ldbills/013/10013.1-i.html?ref=blog.indecol.no) has been put forward in the House of Lords – the Bill seeks to put in place a consumer emissions target (the current UK Climate Change Act which sets an 80% reduction target only addresses production, i.e. territorial, emissions). [Lord Teverson who initiated the bill said](http://services.parliament.uk/bills/2009-10/consumeremissionsclimatechange.html?ref=blog.indecol.no): *“The Defra report considered the position in the United Kingdom in 2004 and came to the conclusion-I was surprised by the accuracy with which the figures can be worked out by academics-that the consumption emissions of the United Kingdom economy were some 37 per cent higher than our production emissions.”*Apart from the fact that this is the first such initiative to base a policy on consumption-based GHG accounting, the statement about the methodology also deserves attention. What is routine for the national carbon footprint analyst might be puzzling to others who are not involved in the calculations: How can one work out all the emissions created somewhere in the world associated with consumption activities in a completely different place?The prevailing method for national Carbon Footprint accounting is environmentally extended multi-region input-output analysis (IOA). In such an environmental-economic model, national input-output tables, representing financial transactions between economic sectors within a country and greenhouse gas emissions data by sector are linked together in one coherent accounting framework with trade flow tables, showing the value of exports and imports by country and economic sectors. Thousands of analysts and researchers use analytical input-output techniques and countless scientific publications have impressively demonstrated the ability of IOA to support the quantification of environmental impacts of economic activities.Despite a politically important and wide-ranging field of applications in carbon footprinting there is still not a widespread acknowledgment of the potential for (hybrid) input-output analysis in other areas. Examples are corporate footprinting which aims at capturing the economy-wide GHG impact of a company and product carbon footprinting aimed at summarising the life-cycle-wide GHG emissions of a specific commodity. One possible reason for this lack of recognition might be the relative initial complexity of implementing environmental input-output models. Specialist knowledge in economic and environmental theory and frameworks is required, the terminology might be more specialised and the input-output mechanism might be intuitively less accessible than the more practical mapping of process flows. Whether due to actual, practical problems or only perceived complexity, few practitioners have so far acquired the skills to carry out (hybrid) carbon footprint or life cycle assessments. However, once established, input-output models are easy to operate and require relatively little data input compared to bottom-up approaches. A Special Issue of the journal Economic Systems Research on [‘Carbon Footprint and Input-Output Analysis’](http://dx.doi.org/10.1080/09535310903541256?ref=blog.indecol.no) has recently been published, featuring six articles ranging from product, corporate and sector carbon footprinting to national and multi-national carbon accounting. The Special Issue brings together state-of-the-art research in environmental-economic modelling with the practice of greenhouse gas accounting at various levels. > [Link to the Special Issue:](http://www.informaworld.com/smpp/title~db=all~content=g919302222?ref=blog.indecol.no) A shirt from a famous season can become a shortcut to remembering goals and rivalries as fans compare old designs with the look of newer campaigns.

The paper published in the prestigious *Proceedings of the National Academy of Sciences* (PNAS for short) uses the same methods, research questions and data sources as our 2008 and 2009 papers. It highlights the role of the most important polluters and largest trade flows by emissions embodiment. According to Davis and Caldeira, 23% of the global CO2 emissions from fossil fuel burning were connected to the production of goods ultimately consumed in a different country. The largest trade flows in terms of pollution required to produce the goods traded (embodied emissions) were from China to the United States, Europe, and Japan. The flows from Russia at Europe and from the Arab Middle East to EU and US were also significant, as was the trade between US and EU (see figure). [News stories on the article in the New Scientist ](http://www.newscientist.com/article/dn18620-us-still-responsible-for-most-co2-emissions.html?ref=blog.indecol.no)and the [BBC](http://news.bbc.co.uk/2/hi/science/nature/8557461.stm?ref=blog.indecol.no) emphasize the point that many European countries have a larger difference in emissions between the consumption and production perspectives than the United States, measured per capita. In other words, the difference in emissions embodied in imports and emissions embodied in exports is larger. In my opinion, this is really not a relevant way of interpreting the results. What counts is the fraction of the national carbon footprint (consumption based emissions) outsourced to other countries. Europe can hardly be criticized for having a much lower emissions intensity than the United States, which is the reason for why the net trade balance is higher for the EU than the US. I think that Davis and Caldeira do a particularly nice job highlighting the increasing specialization of production in the global economy and the differences in the imports and exports of different countries. It is striking that the emissions intensity of exports from Russia, China and India are more than 2 kg of CO2 per $ traded, while those of European countries listed are between 0.17 and 0.25 kg per $. The reason for this difference is most likely a combination of the difference in the emissions intensity of the energy mix, the energy efficiency and the value of the products produced. The split of emissions embodied in trade by traded commodities also indicates the importance of global value chains. The largest flows for most countries shown are “intermediate goods”. The logical next step will be to investigate the makeup of global value chains, analyzing the through-trade of carbon of countries. Given global value chains, how are the carbon footprints of specific products distributed across countries? Davis and Caldeira did not go through the trouble of adding the emissions of non-CO2 greenhouse gases and could also not assess emissions from land use change. As a result, the emissions in some poor countries are very low – 0.12 tons per capita in Ethiopia and Malawi, compared to 22 tons per capita in the United States. As we have observed in our analysis, for such poor countries, the emissions of methane and nitrous oxide from food production are much more important than the emissions of CO2 from fossil fuel consumption. The lower limit for carbon footprints including these emissions are around 1 ton CO2-equivalent per capita. For Norway, the analysis shows that Norway had more emissions embodied in imports than in exports. This is a reversal from 2001, when the emissions embodied in exports were still dominating. The reason for this is a steady increase in import volumes and associated emissions. Emissions embodied in exports remain constant over time, as we will show in a future time series analysis. The paper by Davis and Caldeira, allowing a comparison with our numbers, underlines the importance of emissions embodied in trade. As this paper confirms, rich countries risk fooling themselves by focusing on territorial emissions while their carbon footprints are growing. The objective of climate policy should be to reduce carbon footprints, and not to reduce territorial emissions. This can only be achieved by paying attention to carbon footprints! Retro shirts often bring back the look and emotion of earlier football eras when the difference between player and fan versions becomes part of the discussion. Discussions about supporter identity through shirts show how football apparel connects design choices with supporter habits. For people following national team history, [matchday football shirts](https://www.camisetatienda.com/?ref=blog.indecol.no) is a natural topic when the focus is on design, fit, and supporter meaning. The appeal of a football shirt keeps the focus on clubs, supporters, and the stories behind each design. ### Top Environmental Policy Paper URL: https://blog.indecol.no/top-environmental-policy-paper/ Last updated: 2026-07-16T21:39:23.000Z The Carbon Footprint of Nations has been recognized as the [Top Environmental Policy Paper](http://pubs.acs.org/doi/full/10.1021/es100414j?ref=blog.indecol.no) in 2009 by *Environmental Science & Technology* ([announcement](http://pubs.acs.org/doi/full/10.1021/es100678t?ref=blog.indecol.no)). It is a big honor for us to win that award. *ES&T* is the most important journal in environmental science and environmental technology, publishing 1500 papers in 2009\. We were apparently among 80 papers nominated for the award. Most likely, the popular appeal and policy relevance of our paper was an important factor in our favor. We have previously been awarded by *ES&T*. In 2007, Glen Peters and his collaboration parters won the award for [their analysis of China’s growing CO2 emissions](http://pubs.acs.org/doi/abs/10.1021/es070108?ref=blog.indecol.no), identifying the growth of the urban population and investment in infrastructure as important causes. In 2005, Edgar Hertwich was the runner-up to the Top Environmental Policy Paper for his [review of methods for household carbon footprints](http://pubs.acs.org/doi/full/10.1021/es0497375?ref=blog.indecol.no). Collectors often read football history through collars, sponsors, badges, and colour patterns when the difference between player and fan versions becomes part of the discussion.

Nonetheless, there seems to be wide-spread disappointment among the public. Commentators are busy portioning out blame for the [failure](http://www.guardian.co.uk/environment/2009/dec/18/copenhagen-deal?ref=blog.indecol.no) of the negotiations, where the [U.S.](http://www.guardian.co.uk/commentisfree/2009/dec/21/copenhagen-failure-us-senate-vested-interests?ref=blog.indecol.no), [China](http://www.guardian.co.uk/environment/2009/dec/22/copenhagen-climate-change-mark-lynas?ref=blog.indecol.no), and the unwieldy UN procedures receive the largest shares. Those involved in the negotiations process see Copenhagen as a stepping stone rather than a finish line: they point out that the [Copenhagen Accord](http://unfccc.int/resource/docs/2009/cop15/eng/l07.pdf?ref=blog.indecol.no) keeps going the process towards a final agreement – scheduled for next winter’s meeting in Mexico City. Furthermore, as a first international document to trace developing country commitments, the Accord is necessary to get the US Senate to pass climate legislation. From my perspective, the most remarkable feature of the conference has been that the most difficult arguments evolved around climate justice. The Copenhagen climate conference clearly demonstrates the inadequacy of the political response to the climate challenge. It reflects and is the result of a lack of political will to pursue the necessary changes in development on part of most national governments and their (special interest) constituencies. The politically problematic aspect of the UNFCCC process is that it provides cover for those politicians responsible for inaction on the national level. It allows them to claim that they act – by partaking in the process – and at the same time to blame other parties for the slow progress. We are not on track to reduce greenhouse gas emissions enough to prevent dangerous levels of climate change, and political leaders should not give the impressions that this is a problem they have under control. Far from it! Having said so much, in light of the dismal record of this now ending “lost decade”, the Accord is a quite remarkable document. It acknowledges that global warming should be limited to no more than 2°C, and that a deep cut in greenhouse gas emissions are required to achieve this target. Industrialized countries commit to establishing new targets for emissions cut for 2020, and developing countries commit to implementing mitigation actions. Both targets and mitigation actions will be specified in the coming months. In addition, industrialized countries commit to establishing a Copenhagen Green Climate Fund for financing mitigation and adaptation in developing countries and to establishing a Technology Mechanism for development and transfer of climate-friendly technology. Let’s hope the targets and mitigation action commitments lead to serious actions being implemented, which is what counts in the end. I was surprised about the degree to which the negotiations focused on distributional issues and climate justice, even though I myself had raised these issues in pre-conference interviews. I also thought that the effectiveness of the developing countries coalition (G77+China) was remarkable. Their message was loud and clear: industrialized countries are responsible for (most of) the historical carbon dioxide emissions and they have benefited tremendously from those emissions. It is now the industrialized countries’ responsibility to reduce their emissions first and to provide financial assistance to developing countries both as a compensation for the climate damage already occurring and as a way to share the economic gains incurred as a result of the historical emissions. The [Carbon Footprint of Nations](http://pubs.acs.org/doi/abs/10.1021/es803496a?ref=blog.indecol.no) study shows a remarkable correlation between the national per capita consumption level and carbon footprint. Historical studies also indicate a similar connection between rising incomes and rising fossil energy used. But to what degree is the high energy use the cause of, or the consequence of, economic growth? There is some scientific controversy about this question. A seminal analysis of the United States’ economic development over a 100 year time period by [Bob Ayres and Ben Warr](http://www.sciencedirect.com/science?%5Fob=ArticleURL&%5Fudi=B6VFN-4BSB1PF-1&%5Fuser=10&%5Frdoc=1&%5Ffmt=&%5Forig=search&%5Fsort=d&%5Fdocanchor=&view=c&%5FsearchStrId=1148417332&%5FrerunOrigin=scholar.google&%5Facct=C000050221&%5Fversion=1&%5FurlVersion=0&%5Fuserid=10&md5=a17d39fef024d00a98b4ac49dc66202b&ref=blog.indecol.no) indicates that access to cheap fossil fuels has indeed played an important role in fostering economic growth. Increased input of useful physical work explains more than half of economic growth, while increased input of labour and capital account for the remainder. Physical work is the product of the input of energy resources and the efficiency of energy conversion. If energy input is indeed as central to economic activity as these statistical studies indicate, the access to and price of this energy input is of highest political importance. Fossil fuels and hence CO2 emissions have allowed us to gain access to this energy input at low prices and have hence made possible the unprecedented consumption levels that we enjoy. If access to the atmosphere as a cost-free dump for the waste products of fossil fuel combustion really determines our possible consumption levels, we must not be surprised that this access is subject to really tough negotiations. National leaders are occupied by their countries’, and constituencies’, economic interest. Our atmosphere is a globally shared, common resource that has been over-utilized by a mere 20% of the global population. In principle, all humans should have equal rights to use this resource. The climate negotiations are the only global negotiations allowing developing countries to raise the issue of unfair access to globally shared resources. Their positioning in the negotiations may at times seem self-serving, trying to extract bribes for pursuing a low-carbon development course which should be in the developing countries interest anyway, given their disproportional vulnerability to climate change. It would be a mistake not to take seriously the issue of climate justice and the connection of global resource access and economic product. These issues must be accorded more importance by industrialized countries, which must be more willing to stop their irresponsible overuse of the atmosphere. (For an interesting suggestions of allocating responsibility for emissions reductions, see [this](http://cmi.princeton.edu/research/pdfs/one%5Fbillion%5Femitters.pdf?ref=blog.indecol.no)).

Como comprobación final, conviene asegurarse de que las imágenes muestren el frontal, la espalda y los acabados relevantes. Negotiations must not be a zero-sum game. Yes, we must equitably share our common resources among humans, both current and future generations. However, there is a large scope to improve energy and resource efficiency and to generate energy with much less emissions. International cooperation will in fact help us to take advantage of those opportunities, because it allows us to share technical progress and implement solutions more widely and thereby reduce their price. Still, the climate debate has been so long dominated by technological optimists that issues of justice have been overlooked. I think it is about time to accord them more importance. We must start a debate about how to fairly share our global resources, both in principle and practically. A debate of principles is necessary to make clear to those guilty of too high emissions that the status quo is not right. A debate of practicalities is necessary to find low-carbon development options for poor countries and to avoid transfer mechanisms that corrupt developing country elites and impede development in ways that payments for the extraction of other resources often do. ### Exported Emissions at COP15 URL: https://blog.indecol.no/exported-emissions-at-cop15/ Last updated: 2026-07-29T18:09:30.000Z ![](https://blog.indecol.no/content/images/2020/01/image-14.png) The Guardian and industry actors call for considering Carbon Embodied in Trade as part of a climate deal at Copenhagen. On December 7, 2009, [56 newspapers from 20 countries](http://www.guardian.co.uk/commentisfree/2009/dec/06/copenhagen-editorial?ref=blog.indecol.no) published a joint editorial calling world leaders to use the 14 days of climate negotiations in Copenhagen in order to come to an effective and fair agreement to limit climate change. At the time I am writing this, it is too early to see whether the call will be heeded. The editorial points correctly to what has emerged as the core element of the negotiations: the need to fairly distribute the responsibility for reducing emissions. A critical passage of the editorial, calls for recognizing the issue of[emissions embodied in trade](http://www.eoearth.org/article/Pollution%5Fembodied%5Fin%5Ftrade?ref=blog.indecol.no): Social justice demands that the industrialised world digs deep into its pockets and pledges cash to help poorer countries adapt to climate change, and clean technologies to enable them to grow economically without growing their emissions. The architecture of a future treaty must also be pinned down – with rigorous multilateral monitoring, fair rewards for protecting forests, and the credible assessment of “exported emissions” so that the burden can eventually be more equitably shared between those who produce polluting products and those who consume them. I find it personally gratifying that the issues of forests and trade are finally being recognized, as [we have spend considerable effort to raise these issues](http://springerlink.com/content/1976p75463860416/?ref=blog.indecol.no). Together with Glen Peters and Anders Stømman, I have personally worked on quantifying and modeling the emissions embodied in trade. We have shown that for Norwegian household consumption, most of the carbon footprint is located abroad, where consumer goods and materials are produced. (Our calculations are now included in the official Norwegian climate calculator.) We have quantified the [emissions embodied in trade for all major economies for 2001](http://www.nature.com/climate/2008/0804/full/climate.2008.25.html?ref=blog.indecol.no), using the same data that was also used to calculate the national carbon footprints displayed in this web page. Our results show that in 2001 more than 20% of global CO2 emission was caused by the production of exported products. The [figure](http://www.nature.com/climate/2008/0804/fig%5Ftab/climate.2008.25%5FF2.html?ref=blog.indecol.no) shows single country results from our study. Since then, the fraction has probably increased substantially, as national-level studies suggest. My colleague Richard Wood has just updated the calculations for Norway, which indicate a dramatic growth of the emissions embodied in imports by 50% from 1999 to 2007, while emissions embodied in exports have stayed approximately constant. The changes in the emissions embodied in trade are much larger than emissions reductions due to Norway’s Kyoto target. In the UK, a similar increase in exported emissions has occurred, as results obtained by colleagues at SEI and the University of Surrey show. Maybe the strongest evidence for the global shift in emissions is [evidence from China](http://www.sciencedirect.com/science/article/B6V2W-4T1SFRC-1/2/cf8906ef3be99e992f09a8ef53adb59c?ref=blog.indecol.no), unearthed by [Glen Peters](http://www.sciencedaily.com/releases/2009/02/090224133507.htm?ref=blog.indecol.no), Dabo Guan, Chris Weber and Klaus Hubacek ([Also discussed in the Guardian](http://www.guardian.co.uk/environment/2009/feb/23/china-co2-emissions-climate?ref=blog.indecol.no)). Their modeling indicates that emissions embodied in export have increased from 21% of the total national emissions to 33% from 2001 to 2005, at a time when total emissions increased by 40%. Growth in emissions embodied in China’s export was the most important factor for the exceptional global emissions growth during this period. Why does this matter? Economists argue strongly in favor of economic instruments to reduce global emissions. Carbon pricing provide an equal incentive for reducing emissions both through shifts in energy technologies, through increases in energy efficiency, and through changes in consumption patterns. We will need all these strategies to achieve climate stabilization. If, however, we have unequal carbon prices in different regions of the world, the danger is that carbon intensive production is relocated to where it is cheapest. This is, in any case, where growth is today. If that happens, gains from efficiency and structure are jeopardized. What can be done? Most of the schemes to avoid carbon leakage and the relocation of energy-intensive industries to countries without emissions obligations are subsidy schemes: The EU Emissions Trading System (ETS) provides free emissions quotas to energy-intensive industry. There are plans to compensate the Aluminium industry directly for the high electricity price produced by the ETS. (Only from 2012, and it is not clear whether there will be any Al electrolyses left in Europe to protect.) These schemes all result in reduced costs for energy-intensive products also to consumers in carbon-limited industrialized countries and do nothing to impose the true carbon costs on imports. The only solution that avoids these negative effects is a so-called “border tax adjustment”. This adjustment would imply that an incremental carbon tax is imposed at the border, reflecting the emissions embodied in the product imported. For most products, such a tax would be small. The global average GHG emissions per $ GDP is about 700g. A 100$/t tax implies an average 7% tax. For other products, it would be prohibitive. It would not make sense for Europe to import Aluminium produced with Chinese or South African coal power – but that is precisely the point!

The jury is now in on biofuels: Current government mandates in the United States, Europe and other countries to blend biofuels into ordinary car fuels cause substantial environmental damage, do little to reduce greenhouse gas emissions, and have a questionable contribution to energy security. [A new UN report ](http://www.unep.fr/scp/rpanel/publications/?ref=blog.indecol.no)and [a new book ](http://www.springer.com/engineering/power+engineering/book/978-1-84882-137-8?ref=blog.indecol.no)document many, sometimes fascinating facets of this intricate issue. There are many types of biomass, different options for growing this biomass, a few technologies for converting the biomass to various liquid fuels. It is not surprising that the environmental impacts depend on the particularities of the growing, harvesting, transporting, converting and use of the fuels. However, there are only very few production routes currently used, and these routes are harmful to the environment in several ways. ![](https://blog.indecol.no/content/images/2020/01/image-15.png) The report **“Towards sustainable production and use of resources: Assessing Biofuels”** was produced by the International Panel for Sustainable Resource Management (IPSRM) and relased by the head of the United Nations Environment Program Achim Steiner on 23 October. I am also a member of IPSRM, but have not contributed to this report. The book ‘”**Biofuels for Road Transport: A Seed to Wheel Perspective”**, was written by the Dutch environmental scientists Lucas Reijnders and Mark Huijbregts. Both works present an extensive review of scientific work on biofuels. To understand biofuels, one must look at thermodynamics, that is, to account for energy flows in a biomass system similar to how one would account for money flows. Already in 1982, [Perezblanco and Hannon](http://www.osti.gov/energycitations/product.biblio.jsp?osti%5Fid=6742981&ref=blog.indecol.no) published an analysis of the energy required to produce one unit of energy in the form of corn-ethanol and wood-methanol. They showed that the energy used to run tractors, produce fertilizers, and convert corn to ethanol is more or less equal to the energy in the ethanol produced – so that there is little point in whole exercise. Methanol from wood, however, has a substantial net energy gain. These results have since then been confirmed by a great number of studies, also for other biofuel products derived from these biomass resources. If there is little energy gain, there is also little benefits in terms of greenhouse gas emissions. The figure illustrates the reduction GHG emissions reductions – or the lack thereof – achieved by different biofuel production routes. Today’s biofuel comes all from food crops – maize, wheat, vegetable oil, and sugar cane, which are easy to convert but require high inputs of fertilizer and machine power to produce – with the exception of sugar cane. The substantial insights of the two new publications, however, is the insight of the *high ecological impacts that come from converting land for biofuel production, emissions from land use, as well as the runoff of fertilizer and pesticides*. These effects are often not sufficiently considered in life-cycle assessment. In the United States, it is reported that increased fertilizer application for biofuels has lead to increased runoff of phosphorus and nitrogen, which stimulates increased algae growth in waterways and leads to oxygen depletion and fish death as a result. The issue of land conversion and its effect on carbon stored in soil and plants has been discussed prominently in recent years and months. It is central to determining the greenhouse gas benefit of biofuels. The report underlines that declining yield increases and increasing food demand imply that the current global cropland needs to expand further. Increase biofuels product will hence inevitably require the conversion of virgin land to cropland. Certifying biofuels grown on already established agricultural land has hence little effect, as this only displaces food production to previously marginal land. The effect of this is quite clear, as the report underlines: “*Increased biofuel production is expected to have large impacts on biological diversity in the coming decades, mostly as a result of habitat loss, increased invasive species and nutrient pollution. Habitat loss will mainly result from cropland expansion. Species and genotypes of grasses suggested as future feedstocks of biofuels may become critical as invaders. Nutrient emissions to water and air resulting from intensive fuel cropping will impact species composition in aquatic and terrestrial systems.*” We afford climate mitigation measures that are so ineffective in reducing greenhouse gas emissions but destroy ecosystems and biodiversity. It is time to reconsider biofuel mandates! ### Carbon Market Promises and Woes URL: https://blog.indecol.no/carbon-market-promises-and-woes/ Last updated: 2026-07-29T18:09:33.000Z Economists argue that the carbon market suffices to reduce greenhouse gas emissions and attack additional policy tools for increasing mitigation costs. Time to look at how the carbon market works in practice! In my last blog I have pointed to the [campaign of a few Norwegian economists](http://e24.no/makro-og-politikk/article3315038.ece?ref=blog.indecol.no)against climate policy tools such as the newly established green certificate market, which ensures a higher electricity price for renewable electricity. I published a similar critique in Dagens Næringsliv, a business daily. The prompt response by Professor Michael Hoel of the University in Oslo was that I did not understand the quota market. Professor Hoel lectured me on basic microeconomics, pointing to the fact that increased renewable energy would lead to reduced prices for emissions allowances and hence increased emissions somewhere else in the European Emissions Trading System (ETS). The emissions reductions achieved through subsidies for energy efficiency or renewable would necessarily be more expensive than the marginal emissions reductions in the ETS. The response did not my argument that technology learning required niche markets which the green certificates created, and that without new technologies we would not be able to reduce emissions sufficiently. Instead, Hoel suggests that [Norway should buy large amounts of emissions allowances and retire them](http://e24.no/kommentar/article3281991.ece?ref=blog.indecol.no) – just to drive up the price. Let’s have a look at how the carbon market really works to see what would happen. The [EU ETS](http://ec.europa.eu/environment/climat/emission/index%5Fen.htm?ref=blog.indecol.no) has been in operation since 2005, and the market for project-based mechanisms has existed even longer. The experience with these markets provides a good basis for assessing the ability of carbon market to address the climate crisis. In the European carbon market, large industrial facilities and power stations require emissions allowances (EUA) for every ton of CO2 they emit. Allowances are distributed by governments to cover most, but in theory not all of the needs by industry. The problem in the first period 2005-2007 was that[some national governments had given out too many allowances](http://news.bbc.co.uk/2/hi/science/nature/5126402.stm?ref=blog.indecol.no). Up until the EUA market collapsed in 2007, the price varied in the €10-30 per ton range ([Fig.2.5 in Carbon 2008](http://www.pointcarbon.com/polopoly%5Ffs/1.912721!Carbon%5F2008%5Fdfgrt.pdf?ref=blog.indecol.no)). In that period, it became obvious that power companies who had allowances for free passed almost all of the costs through to the customers – as if they had paid for the allowances. As a result, the carbon market generated [windfall profits](http://www.economist.com/research/Economics/alphabetic.cfm?term=windfallprofit&ref=blog.indecol.no#windfallgains) for power generators and redistributed tens of billions of Euros from electricity [consumers](http://www.cembureau.be/Cem%5Fwarehouse/2-INDIRECT%20IMPACT%20OF%20EMISSIONS%20TRADING%20ON%20ELECTRICITY%20PRICES.PDF?ref=blog.indecol.no) to producers – apparent in the balance sheet of utilities. ([BBC documents new examples of windfall profits](http://news.bbc.co.uk/2/hi/science/nature/8164042.stm?ref=blog.indecol.no).) The overallocation of EUAs and the resulting collapse of the carbon market was an embarrassing for the European Commission, which responded by restricting the national allocation of allowances by member states for the 2008-2012 period. Estonia and Poland were not satisfied with the amount of allowances they were allowed to distribute and sued the EC in front of the European Court of Justice. In September 2009,[ the Court ruled in favor of Estonia and Poland](http://news.bbc.co.uk/2/hi/europe/8273016.stm?ref=blog.indecol.no). It said it was up to member states not the EC to set national emissions targets. It is uncertain how this wrangle will continue, but Eastern European member states have received a joker in the political tug-of-war about emissions rights. The very political nature of the process by which emissions allowances worth billions of Euros are created and allocated was also apparent in [the negotiations about the continuation of the European ETS for the 2013-2020 period](http://news.bbc.co.uk/2/hi/europe/7780700.stm?ref=blog.indecol.no). In a recommendable move to improve the system, the European Commission proposed to sell the emissions allowances instead of giving them away for free, something that would make the system a lot better. Industries which are exposed to tough international competition would continue to receive free allowances. Poland managed to negotiate an allocation of free allowances to its power sector – which certainly is not exposed to international competition from outside the ETS area! The argument was that Polish industry and households could not bear the high electricity prices. If experience with the ETS is any guide, Polish utilities will pass on the carbon costs to their customers and take the free allowances as a subsidy. Now, one can imagine what the reaction of EU countries would be to a sudden purchase of a large amount of emissions allowances by the Norwegian government. Instead of allowing the carbon price to rise, EU governments would simply distribute more allowances, thus turning the Norwegian purchase into a subsidy for allowance-receiving industry. Polish coal-fired power stations are favored candidates for receiving these gifts of Norway. There is plenty of documentation of phony projects and cheating at the heart of the project-based emissions reductions, especially Clean Development Mechanisms. It reminds me of the story of economic incentives for catching rats, which some Caribbean government had tried as a measure to control this pest. At first, it brought down the density of rats, but then it gave rise to organized rat breeding. The [International Energy Agency ](http://www.iea.org/W/bookshop/add.aspx?id=370&ref=blog.indecol.no)has now proposed a different mechanism for providing incentives to emissions reductions in developing countries. One may wonder how the carbon market would work if politicians managed to solve the problems with allocation and cheating. There is another aspect which is not normally reflected in the economists’ models: the variation of the carbon price in response to economic cycles, uncertainty and imperfect information. The economic risk to investors in energy technology posed by the medium-term uncertainty in the quota price is a significant deterrent to investments, [as energy companies recently told a hearing by the UK House of Commons](http://www.guardian.co.uk/environment/2009/apr/29/carbon-trading-warning-emissions?ref=blog.indecol.no). It is totally unnecessary to generate such a varying price signal because we know already today that in the long run, polluting fossil power stations are not acceptable.

Las fotografías y la ficha del producto deberían confirmar la guía de tallas y el espacio previsto para capas. I agree with an increasing number of analysts that emissions allowances should be replaced by a pollution tax, which is simpler to implement, gives much less opportunity to cheat the system or achieve huge gains through lobbying. The problem with carbon pricing in general and a tax in particular is that it costs the public a lot, and that the amounts of money that needs to be rechanneled are much larger than the marginal changes in investment costs that are affected by this policy. The political price of carbon pricing is hence high. To limit that price, it is advantageous to also use more targeted, effective policy tools to achieve emissions reductions, such as energy efficiency regulations for houses, cars, and gadgets, subsidies for all sorts of technology development, information tools, and subsidies/niche markets for emerging low-carbon technologies. Emissions allowances are funny money – a fantasy creation that works well in economists’ highly stylized model world, but unfortunately not (yet?) in reality. It is time that economists return to their forefathers’ understanding of “political economy” (which considers the interests of different parties) and observe real markets before intervening in politics. ### Hurra for Green Electricity! URL: https://blog.indecol.no/hurra-for-green-electricity/ Last updated: 2026-07-07T00:10:41.000Z Some economists argue that support for renewable electricity leads to more coal power. Their reasoning is curiously flawed and oversees the crucial role of technological learning. A curious discussion about climate policy has arisen in Norway now that the country has agreed with Sweden to join Sweden’s ”[green certificate](http://www.eoearth.org/article/Green%5Fcertificate?ref=blog.indecol.no)” market (a.k.a. el-certificate, similar to the [renewable portopholio standard](http://en.wikipedia.org/wiki/Renewable%5Fportfolio%5Fstandard?ref=blog.indecol.no)) . This policy tool creates de-facto a niche-market for specific kinds of renewable energy, which are traded at higher prices than on the spot market for electricity. Economists like [Böhringer and Rosendahl](http://www.ssb.no/publikasjoner/DP/pdf/dp581.pdf?ref=blog.indecol.no), Michael Hoel and Odd Godal (DN 9 and 11 Sept.) now argue that the increased production of renewable electricity in Nordic countries will have no effect on the emissions of greenhouse gases in Europe, and it may even contribute to increasing greenhouse gas emissions globally by leading to a reduced price of fossil fuels. ![86018-learning2](http://69.195.124.91/~carbonf5/wp-content/uploads/2009/09/86018-learning2.gif) On some level, the argument is really silly: Since lawmakers have set absolute limits on the allowed emissions, reduced production of coal-based electricity in Scandinavia will free up emissions allowances which will be used somewhere else in Europe to emitt CO2\. The support for renewable energy hence undercuts other emissions-reducing efforts. Of course, the same argument can be applied to any emissions-reducing effort anywhere within the EU’s cap! If the argument is hence followed through and applied everywhere, everybody would stop their emissions-reduction efforts, and there would be no reduction at all. Europe would fail it’s goals to reduce emissions. Renewable electricity is one of the many measures required to achieve emissions reduction targets and is hence not futile. Of course the econmists could respond that I misread their argument, which could be more subtle than it comes across in the media: Dedicated support for renewable electricity reduces the quota price (which is part of the argument) and hence leads to a shift in what measures are adopted to achieve the goal. Instead of energy conservation in Poland, you get wind power in Norway, but on total the measures are (not necessarily, but possibly) more expensive. That’s fair, in the economists’ idealized world, having one emissions price as the only policy tool to achieve emissions reductions is most efficient. However, this oversees some crucial realities. First and foremost, there are other criteria than efficiency which affect the desirablity of a policy, such as political feasibility and distributive justice. There is a limit to level of carbon and electricity price that is politically acceptable, and that limit varies by country. Poland has already managed to negotiate concessions from other EU countries: a large allottment of free emissions allowances their coal-fired power plants. Sharing the pain of emissions reductions means that also in countries high cost level measures will have to be implemented, even if they are more expensive. Second, if it is easier to achieve the emissions reductions aimed for in 2012, the ambition level for the next period will be higher. Hence, the amount of emissions is not really fixed as the reasoning of Böhringer and Rosendahl implies, but depends on the ease and success of effort to reduce emissions, and the green certificates will help this effort. Besides, the installed renewable plants will be in operation beyond the time horizon of existing cap-and-trade systems. Third, carbon pricing strategies such as the [EU’s Emissions Trading System lead to windfall profits](http://www.indecol.ntnu.no/indecolwebnew/publications/newsletter/webnews/webnews3%5F05.htm?ref=blog.indecol.no): anybody who already has low-emissions power production such as large hydro or nuclear plants profits from the resulting increase in electricity price. The amount of money redistributed to owners of existing facilities is much larger than the investment costs for the required emissions reductions, as I have argued elsewhere. Of course t here are other arguments for high electricity prices, as these lead to conservation. However, this can be achieved through taxes which benefit the general public instead of multi-billion Euro windfall profits for power companies. By reducing the quota and hence electricity price, subsidies for renewables reduce the windfall profits of power companies, which should be seen as a good thing. Fourth and most importantly, niche markets are required for new technologies to mature and bring down cost. As [Wright ](http://en.wikipedia.org/wiki/Theodore%5FPaul%5FWright?ref=blog.indecol.no)has shown in an analysis of the cost of making air planes published in 1936, costs are reduced with cumulative production because of [technological learning](http://www.ifm.eng.cam.ac.uk/csp/summaries/learningcurve.html?ref=blog.indecol.no). [This has been extensively documented also for energy technology](http://www.iea.org/textbase/nppdf/free/2000/curve2000.pdf?ref=blog.indecol.no): for successful technologies, a doubling of cumulative production brings on average a 20% reduction in per-unit cost ([Figure source](http://energy.jrc.ec.europa.eu/Pages/ArticlesETD.htm?ref=blog.indecol.no)) Niche markets are required to provide an opportunity for improving the technology, working out the kinks, developing the organisation of new value chains. Policy support for nacent technologies is hence justified by long-term benefits that the development of these technologies brings. While this ”technology learning” rationale has been central for creating the green certificate markets and similar policy initatives, it has been totally ignored in the economists’ arguments against these instruments. While I don’t think that renewables alone are sufficient to stop climate change and more fundamental changes to our economies are required, they are an indispensible element of any climate strategy. Green certificates could be criticized for being less effective in supporting new technology than feed-in tariffs, the successful approach taken e.g. by Germany, but better some support than none. ### Can Technology Spare the Earth? URL: https://blog.indecol.no/can-technology-spare-the-earth/ Last updated: 2026-07-29T18:09:38.000Z The IPCC says that we need to reduce greenhouse gas emissions by at least 80 % by 2050 to achieve the goal of limit global warming to not more than 2°C, agreed to by the EU and the G8. [Recent research](http://www.nature.com/nature/journal/v458/n7242/abs/nature08017.html?ref=blog.indecol.no) indicates that the cumulative emissions in the period 2000-2050 should be not more than 1000 billion tons of CO2\. In the first 7 years of this 50 year period; 234 billion tons were already emitted. Even if we give up the 2°C goal, risking unpredictable feedback mechanisms disrupting the climate in more severe manners, quick, deep emission reductions are required to stabilize atmospheric CO2 concentrations. Given that energy access is so essential for the economy, we need to ask ourselves: How can such reductions be achieved? What is the role of technology, behavior change, and a change in our path of development? It appears that policy makers and too many scientists have already made up their mind. Technology is the solution! I was reminded of this again by Norway’s Minister for Environment and Development, [Erik Solheim](http://www.regjeringen.no/en/dep/md/About-the-Ministry/minister-of-the-environment-and-developm.html?id=486338&ref=blog.indecol.no), who started his speech on the political prospects for climate protection at NTNU with a rhetorical question of where we would stand without technology today, pointing to the increase in life expectancy from 40 to 70 years since the industrial revolution. Without technologies, it would be back to the caves. Solheim’s rhetoric contributes to making a taboo of any other solution strategy, something we can ill afford in the precarious situation we have put ourselves in. Of course technology is an indispensible part of the solution! It would be impossible to even feed the current population 6.9 billion without technology, not to talk about the 9 billion we expect by 2050\. Alluding to a life in the caves, however, it not helpful when we consider how we could lower our carbon footprint to less than one ton per person and year, from 15-30 tons in developed countries today. One needs to ask whether technology is sufficient, or whether other changes are required as well? What are the environmental, social and monetary costs of technological solutions, compared to other approaches? I see that the exclusive focus on technology clouds our thinking about the implications of climate change for our development. The past century and a half have brought tremendous economic development. The quality of life of individuals has improved greatly, and a household’s possessions of everything from living space to clothing and gadget have grown substantially, at least in the rich quarter of the global population. Many take the expression *sustainable development* to imply that the less wealthy and very poor would catch up with us, but also that we would continue the expansion of possessions and travel distances as we have done in recent decades. The base-line of our energy scenarios is such economic development, where business-as-usual implies that it occurs using incrementally improving technology with improvement corresponding to current rates (1% energy efficiency gain per year, technology learning for new energy technologies), while mitigation scenarios imply the adoption of different energy technologies to satisfy the needs of the ever-expanding economy. In the mind of policy makers, technology is the ultimate band-aid that solves the CO2 pollution problem from energy, allowing for a continued expansion of energy services without any limits. The trouble is that this perspective is not even supported by the energy technology models from which it has emerged. My reading of the International Energy Agency’s [Energy Technology Perspectives ](http://www.iea.org/Textbase/techno/etp/ETP%5F2008%5FExec%5FSum%5FEnglish.pdf?ref=blog.indecol.no)is that climate mitigation to the 2°C level is simply not possible if the economy develops along a baseline scenario. One reason is certainly food production, which already causes more greenhouse gas emissions that we can afford globally from all consumption activities. There it is methane from cows, nitrous oxide emissions from soils and the fate of soil organic carbon which play an essential role. This leaves little room for emissions from the energy system. Even if we go to totally fossil-free energy technologies, material production will require the oxidation of carbon. Furthermore, there are resource constraints which affect carbon-free energy production. Jesse Ausubel, from whose influential [1996 American Scientist article](http://phe.rockefeller.edu/sparetheearth/?ref=blog.indecol.no) I borrowed the title of this blog, has pointed out that the [limited availability of land](http://www.inderscience.com/storage/f651710118931242.pdf?ref=blog.indecol.no) constrains all renewable sources. The increasing opposition to wind power projects indicates that maybe we want to keep part of nature for other purposes. Nuclear fission has its own resource limits. In addition, concerns about proliferation need to be taken seriously in today’s world. I think it should be possible to achieve our current level of material wealth with much lower greenhouse gas emissions, even though I would like to see the feasibility of a <1 ton per year carbon footprint demonstrated by model calculations that take both life-cycle emissions and resource limits into account. The current development path, however, does not stop there. The wealthier the individuals, the more air travel they do, and there is no technology on the horizon to take carbon out of the aviation business. Richard Branson’s Virgin Galactic vision and enterprise demonstrates that we are on the trajectory to commercial space-flight being available to the upper classes. Such a development can never be sustainable. We need to simply acknowledge the resource limits on this planet and to change course towards a development that occurs within these limits. The limit on greenhouse gas emissions is one crucial limit, but limits on the yields of fish stock and land, as well as of energy and material resources, are also important. It is not that we need to halt economic growth – only totalitarian regimes can put a lid on human ingenuity – but that we need to change the direction in which the economy develops. Innovations and growth which rely on more energy, more resources need to become impermissible. Enforcing such constraints will provide a new set of opportunities for innovation and technological development, for cultural expression and human well-being in harmony with nature.

We are still far away from having the constraints and price signals in place under which economic growth could be environmentally beneficial. As such, the current economic crisis is a blessing and an opportunity to use the involuntary pause to change course, to reorient development, to [green the economy](http://www.unep.org/greeneconomy/?ref=blog.indecol.no). There are some efforts in that direction, but they need to be strengthened dramatically. ### What does the Carbon Footprint mean? URL: https://blog.indecol.no/what-does-the-carbon-footprint-mean/ Last updated: 2026-07-07T00:10:59.000Z **Many people have asked how a country’s carbon footprint compares to the territorial emissions reported to the United Nations Framework Convention on Climate Change (UNFCCC)?** In hindsight, it was perhaps remiss of us not to include this data in the paper. However, it was not our motivation. Focusing on whether the emissions are bigger or smaller misses a large part of the story. The main focus of the paper is on what consumption categories cause emissions and how this varies across countries with different incomes. The current approach in the UNFCCC reveal what the emissions are from electricity, transportation, and so on. This is vital information, however, only a carbon footprint can reveal what the emissions are to produce food, car, television, or to get a hair cut. This information is needed by consumers if they want to reduce their own personal footprint ([http://www.springerlink.com/content/1976p75463860416/](http://www.springerlink.com/content/1976p75463860416/?ref=blog.indecol.no)). The real value of a carbon footprint is the information it reveals, not necessarily if the footprint is bigger or smaller than the territorial emissions. In a broader global perspective, if a country’s carbon footprint grows over time relative to territorial emissions then it means that the country is increasingly importing products at the expensive of domestic production. If that country has an emission limitation in the Kyoto Protocol and the imports are coming from countries without emission limitations then global emissions may increase while it “appears” emissions are decreasing. This is known as carbon leakage ([http://www.nature.com/climate/2008/0804/full/climate.2008.25.html](http://www.nature.com/climate/2008/0804/full/climate.2008.25.html?ref=blog.indecol.no)). In fact, this is what is happening now. Since 1990 the emissions in countries with an emission limitations have largely stabilized, while the emissions in countries without emission limitations have increased about 80%. The main reason for this is the explosive growth of China, however, recent research has shown that about 50% of the growth in Chinese emissions since 2000 is due to the production of products exported from China and consumed in other countries ([http://www.agu.org/pubs/crossref/2009/2008GL036540.shtml](http://www.agu.org/pubs/crossref/2009/2008GL036540.shtml?ref=blog.indecol.no)). An analysis of the carbon footprint is useful for an analysis of carbon leakage, but the footprint better measured another way ([http://dx.doi.org/10.1016/j.ecolecon.2007.10.014](http://dx.doi.org/10.1016/j.ecolecon.2007.10.014?ref=blog.indecol.no)). The carbon footprint in our article only directly considers trade to final consumers (such as households) and trade to industry is calculated internally in the model. Thus, the footprint of the USA includes emissions that occur to extract iron-ore in Australia, to produce steel in China, to produce a car in Japan, which is consumed in the USA. While this is perfectly logically, it means that the imported emissions are not directly comparable to the import statistics which only consider the first trading partner (the trade from Australia to China is not included in the US trade statistics). To make trade statistics and imported emissions consistent it is more intuitive to consider only the first link in the supply chain, but include imports to both industry and final consumers. This method was used in another of our papers ([http://pubs.acs.org/doi/abs/10.1021/es072023k](http://pubs.acs.org/doi/abs/10.1021/es072023k?ref=blog.indecol.no)) and we call a Consumption-Based Inventory. In the two different approaches the imported emissions differ, but the exported emissions need not differ if the arithmetic is done correctly. In the Carbon Footprint of Nations paper, the imported emissions cover the global emissions required to produce the final consumption in each country, while in a Consumption-Based Inventory the imported emissions cover the domestic emissions in each country to produce total (final and industry) consumption in each country. If trade to industry and final consumers is include, then only domestic emissions are included to avoid double counting. Both approaches do lead to some confusion, but they serve a different purpose. A Carbon Footprint tells us what consumption categories are important and how we may reduce emissions by consuming differently. The Consumption-Based Inventory focuses on trade relationships and how the trade relationships redistributed emissions between countries. Depending on the question being asked, one method is usually preferred. ### News Stories on Carbon Footprint of Nations URL: https://blog.indecol.no/news-stories-on-carbon-footprint-of-nations/ Last updated: 2026-07-07T00:11:09.000Z A good week has gone since the release of the website and the [online version of our article](http://pubs.acs.org/doi/abs/10.1021/es803496a?ref=blog.indecol.no). A number of news outlets picked up the story, including the venerable [Neue Züricher Zeitung](http://www.nzz.ch/nachrichten/forschung%5Fund%5Ftechnik/der%5Fklimatische%5Ffussabdruck%5Fdes%5Fkonsums%5F1.2755249.html?ref=blog.indecol.no) (Switzerland) and the tabloid VG (Norway). It was really interesting to discuss our research with numerous journalists and to see what they picked up. Here is some highlights. - Consumption as key driver for carbon footprints: Basically all stories emphasize the importance of goods for personal and national carbon footprints. [ETH Life](http://www.ethlife.ethz.ch/archive%5Farticles/090619%5Fhertwick%5Fuh/index?ref=blog.indecol.no) and [pressetexte](http://pressetext.com/news/090622022/shopping-beeinflusst-das-klima/?ref=blog.indecol.no) show ladies shopping. (Ironically, men usually have higher carbon footprints and are traditionally responsible for shopping high-impact items.) The news stories also point out that increased consumption leads to increased carbon footprints and that this tendency does not level off even at high expenditure levels. There is no [“Kuznets curve”](http://www.eoearth.org/article/Environmental%5Fkuznets%5Fcurve?ref=blog.indecol.no) for carbon footprints. This message is very much part of our intention to alert the world to the fact that, even when consumed goods or services do not require energy for their consumption, they cause greenhouse gas emissions during their production and consumption. - The outsourcing of carbon footprints: The news stories also focus on the contribution of countries to the climate problem and on how this contribution changes if we take [emission embodied in trade](http://www.eoearth.org/article/Pollution%5Fembodied%5Fin%5Ftrade?ref=blog.indecol.no) into account ([1](http://www.alphagalileo.org/ViewItem.aspx?ItemId=58827&CultureCode=en&ref=blog.indecol.no),[2](http://www.forskning.no/artikler/2009/juni/223512?ref=blog.indecol.no)). Our analysis shows that for most OECD countries, the emissions caused by the production of imports are clearly higher than that caused by the production of exports. A carbon footprint accounting would have clear implications for the assignment of responsibility for future emissions reduction. In the interviews, I have emphasized the importance of using carbon footprints as a complementary indicator to the conventional national emissions inventories in international climate policy. We want to ensure that measures that are taking to not lead increases in emissions somewhere else. I would also argue that the development of the national carbon footprint over time is much more relevant for the success of climate policies than the development of national emissions. - Some stories have also picked up on the relevance of the results for integrated product policy. Our study has focused on the importance of eight different consumption categories. Integrated product policy [(IPP)](http://ec.europa.eu/environment/ipp/?ref=blog.indecol.no)has been successfully applied by the EU to influence the content of electronic products, reducing toxic compounds, and to reduce energy consumption of energy using products. Now the EU is interested in extending product policy to also reduce energy use in the manufacturing of the products. Our study will hopefully help the EU to target its policy on the largest problems. ### The importance of national carbon footprint accounting URL: https://blog.indecol.no/the-importance-of-national-carbon-footprint-accounting/ Last updated: 2026-07-29T18:09:41.000Z **Congratulations to Edgar Hertwich, Glen Peters and the NTNU team for presenting the ‘Carbon Footprint of Nations’ as a politically relevant way of accounting for greenhouse gas emissions, based on a sound methodology.** The publication and website comes at an important time – the decisive climate policy negotiations in Copenhagen are only half a year away – and it will be a useful input to this process. For both, producers and consumers, as individuals, companies and nations are responsible for emissions and both have a joint responsibility to address the problem with determination. The burden of this responsibility must be shared, only then can a meaningful and comprehensive deal to cut global emissions be achieved. The exact nature of this sharing is yet to be determined in negotiations but it is certainly useful to provide the viewpoint of both, production-based and consumption-based emission inventories. The work is also important from a methodological point of view. Whilst it is, of course, not the first publication to present findings from an environmentally extended multi-region input-output (EE-MRIO) model (numerous other researchers and the authors themselves have driven forward this field of research), it clearly emphasises the applicability and usefulness of this method. The consistent combination of existing, mostly standardised, environmental and economic accounts and the unambiguous allocation of impacts to consumption categories are the strengths of EE-MRIO. It is also an acknowledgement that international trade is the key element in separating production from consumption in a globalised world and that the complex trade relationships need to be addressed in a methodological sound manner. Clearly, much more needs to be done to make the method robust enough for political target setting. An upcoming report from the recent European EIPOT project makes suggestions on methods, data and institutions to develop EE-MRIO in that direction ([www.eipot.eu](http://www.eipot.eu/?ref=blog.indecol.no)). Looking at greenhouse gas emissions from a consumption perspective is politically significant and addresses arguably the most important environmental challenge faced to date. But it cannot provide the full picture of relevant impacts and it will be necessary to monitor other indicators alongside the carbon footprint, such as the ecological footprint, water footprint and results from more specialised ecological impact models, informing about biodiversity, ecosystem health and other categories.

I wish the ‘Carbon Footprint of Nations’ website plenty of attention and hope it helps in conveying the message of consumption-based accounting. ### Welcome to the Carbon Footprint site! URL: https://blog.indecol.no/welcome-to-the-carbon-footprint-site/ Last updated: 2026-07-07T00:11:25.000Z **We are excited about launching this web site. Many years of our research have gone into developing models and analyzing data on the connection of industrial production, consumption and environmental pressures.** Profound insights have been gained, and an approach has matured which we think is indispensible to address climate change and resource scarcity. Now, we feel that the world really should pay attention! We want to use this website to communicate our research findings to a broader public and to enter into a dialogue with those interested. Climate change is now increasingly acknowledged as the most urgent global environmental problem. Humans have changed the composition of the atmosphere in a manner that disturbs our planet’s energy exchange with the rest of the universe, thereby leading to a small but measurable increase in temperature on our planet. The main process by which we have changed the atmospheric composition is combustion. Combustion happens on fields, in industry, in stoves and car engines, mostly intentionally and for a specific purpose. Our problem is that while politicians are waffling about how to address the climate challenge, the rate at which the concentration of greenhouse gases increase is itself increasing. [Energy consumption increases](http://www.bp.com/productlanding.do?categoryId=6929&contentId=7044622&ref=blog.indecol.no), and the [fraction of carbon dioxide absorbed by the biosphere and oceans may be going down](http://www.globalcarbonproject.org/?ref=blog.indecol.no). It is hence important to act – but to act, we need to know what to do. The occasion of opening this website is the publication of a paper by Dr. Glen Peters and myself, modeling and analyzing the carbon footprint of 73 nations. Here you can find out whether, in your country, it is nutrition which contributes most to the average person’s footprint, housing or mobility. You can see how your country does, compared to others, and how much of the carbon footprint is due to imported goods. Our main message is: all of our purchases are relevant to the climate. The attention often focuses on the direct use of energy. Yes, that is where we are causing the highest emissions of greenhouse gases per unit money spent. But on the aggregate, the emissions caused by the production of goods and services we consume are more important. We need to reduce both direct and indirect. We need to be careful that the reduction of direct emissions does not shift emissions elsewhere. Of course, the problem is exceedingly complex, and there is much more to the story than the headline. I hope this website will be able to shed some light on important aspects that have often been overlooked.
