The Federal Foreign Office and the Goethe-Institut have invited leading experts from fifteen countries on a trip to provide insights into climate change impacts and adaptation measures in Germany. On May 13, 2024, the delegation visited the Institute for Ecological Economy Research (IÖW). Professor Jesko Hirschfeld and Johannes Rupp discussed climate adaptation strategies and the costs of the climate crisis with the visitors. more

Who can take responsibility for steering problematic developments in AI back in the right direction? This is the question addressed in the third and final issue of the SustAIn magazine. Before the EU starts the final negotiations on the AI regulation on 6 December 2023, AlgorithmWatch, the IÖW and the DAI Lab at TU Berlin provide an up-to-date overview of the sustainability impacts of AI – from AI resource consumption through online marketing to the water footprint of AI systems. The project was funded by the German Federal Ministry for the Environment. more


To strengthen economic and social cohesion within the European Union, the European Commission provides “cohesion funds”. These make up around a third of the EU budget. To date, the funds have mainly been used for roads, motorways and bridges in structurally weak regions. Since 2021, cohesion policy should also take much greater account of environmental goals, such as the Paris Climate Agreement. An Academic Sounding Board is now to help channel investments in a sustainable way. Florian Kern, research group leader at the IÖW, has been appointed to the board, which will meet for the second time on 22 November 2023. more
