Material production accounts for close to a quarter of global greenhouse gas emissions, but receives little attention compared to energy, meat, or deforestation. In a new report for the International Resource Panel, we show that reducing the use of emissions-intensive materials such as metals and cement in buildings and

With current efforts or those committed to under 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. This finding emerges from a special report of the Intergovernmental Panel on Climate Change (IPCC)

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. Conversely, metal use

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

While Donald Trump withdraws the US from the Paris climate agreement, the world has tools to reduce the US carbon footprint As the world is in shock about Donald Trump’s erratic but not unexpected decision to withdraw the United States from the Paris climate accord, reactions range from the

But are they really better than fossil fuels and nuclear

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 Economics of Energy – What is the cost-effectiveness of energy and climate policies? In a panel debate 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 in recent scientific work.

The Intergovernmental Panel on Climate Change 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: Trillion tons of CO2

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 shows. By Edgar Hertwich, Thomas Gibon and Anders Arvesen, NTNU The use of fossil energy sources has made it possible for
