Tobias Haas studied economics and political science at the FU Berlin and the University of Copenhagen (Denmark). In his doctorate in Tübingen he dealt with the controversies about the energy transition in Germany, Spain and in the European context. As a post-doc at the FU Berlin, he worked on the mobility transition in Germany and the EU. In the summer of 2018, he was a fellow at the Kolleg Postwachstumsgesellschaften at the Friedrich-Schiller-University in Jena and has developed ideas on the extent to which post-growth debates can inspire the mobility transition. From 2018 to May 2022, he worked as a research associate at the IASS in Potsdam in the project „Social Transformation and Policy Advice in Lusatia“ and since April 2022 at the RIFS in the project Carbon Dioxide Removal Synthesis and Transfer Project within the research group „Planetary Geopolitics and Geoengineering“. His research focuses on the intersection of political economy and political ecology with an emphasis on climate change.
