by Ranran Wang and Edgar Hertwich 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
Summary: Concerned about economic growth, China and India weakened the COP26 Glasgow Climate Pact. 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
The production of materials causes a quarter of global greenhouse gas emissions [https://www.nature.com/articles/s41561-021-00690-8]. 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
Nobody is as affected by the damaging forces of climate change as underdeveloped countries, but these countries face a paradox as they try to mitigate their CO2 emissions. Improving the lives of their citizens will increase the demand for energy and materials — which in turn will make climate change worse.
Material production accounts for close to a quarter of global greenhouse gas emissions [https://osf.io/preprints/socarxiv/n9ecw/], but receives little attention compared to energy, meat, or deforestation. In a new report for the International Resource Panel [https://www.resourcepanel.org/reports/resource-efficiency-and-climate-change], we show that reducing the use
With current efforts or those committed to under the Paris agreement [https://unfccc.int/process-and-meetings/the-paris-agreement/what-is-the-paris-agreement] , there is absolutely no chance that humanity will limit the warming of the Earth’s surface to an average of 1.5 degrees Celsius [https://www.theguardian.com/environment/2018/sep/26/global-warming-climate-change-targets-un-report?
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/
A potential increase in metal consumption emerges as only concern in a broad-based investigation of the clean-energy transition The history of environmental protection is full of unforeseen consequences: taller chimneys only led to pollutants spreading wide and far, and safe refrigerants replacing hydrocarbons turned out to damage the ozone hole.

We think of capital, the assets we use in production, as heavy: machines, buildings, infrastructure, trucks and railroads. 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
An alternative theory for climate change based on the influence of cosmic radiation lead to prominent predictions of an imminent cooling of global temperatures. Three years after the book by Fritz Vahrenholt and Sebastian Lüning was a bestseller in Germany and translated into English, its predictions – popular with climate sceptics
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/] (IndEcol) of the Norwegian University of Science and Technology (NTNU).

The Economics of Energy – What is the cost-effectiveness of energy and climate policies? In a panel debate [https://www.youtube.com/watch?v=zcL4WTeGmPo] with key European policy makers hosted by GE and organized by ScienceBusiness; I emphasized the need to more systematically internalize environmental costs, which we have enumerated
The Intergovernmental Panel on Climate Change [http://www.ipcc.ch] shows that hope is not forsaken: rigorous climate politics locally and nationally has spurred development of new technology sooner than expected. Increased pressure in the pursuit of climate protection is still required to reach the 2°C Target. Carbon Budget:
If we want to limit air pollution and reduce greenhouse gas emissions while meeting unmet demand in developing countries, renewable electricity is a promising option, as our new research [http://dx.doi.org/10.1073/pnas.1312753111] shows.

After 4 years of intensive work, the fifth assessment report of climate change by the Intergovernmental Panel on Climate Change (IPCC) [http://mitigation2014.org/]has finally been published. It says that it is urgent to begin reducing emissions, otherwise we will not be able to stay below the articulated limit

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_Vahrenholt] and spot on the best-seller list.

It is a sad result of human civilisation that we are driving other species into extinction. A new study [http://www.nature.com/nature/journal/v486/n7401/full/nature11145.html] highlights the main driving forces – rich countries’ consumption. Humans have always affected their environment.
