Alongside digitalization, climate change is the megatrend of our time. Our economy is still largely dependent on fossil energies. How must the economy be shaped so that it is in harmony with the environment? What does an economically efficient and socially acceptable climate policy look like? How can energy needs be met more and more from renewable sources? Can the transformation to a circular economy succeed? These and other questions are addressed by the Environment Energy Infrastructure competence area at the Institute of German Business.
