Professor Felix Mormann gave a guest lecture on U.S. climate change policy at the University of Marburg, Germany. Following an invitation from Professor Monika Böhm, Professor Mormann discussed the implications of Massachusetts v. EPA leading up to EPA’s proposed rules to address greenhouse gas emissions from existing fossil fuel-fired power plants. Professor Mormann’s scholarship explores the financial, regulatory and policy challenges along the path to an environmentally and economically sustainable energy future. He teaches in the areas of contracts, environmental law, energy law, and climate change.
