Biomass is currently the EU’s largest renewable energy source, but climate strategies often focus on other energy sources. A comprehensive analysis, led by Chalmers University of Technology in Sweden, now shows that biomass is crucial for Europe's ability to reach its climate targets, as it can be used to produce fossil-free fuels and chemicals and also enables carbon dioxide removal from the atmosphere. If biomass were excluded from the European energy system, it would cost an extra 169 billion Euros per year – about the same as the cost of excluding wind power.
