From May 3 to 5, 2023, our nationwide teacher training on climate change in schools took place in the picturesque city of Weimar. Initiated and organized by our educational program "Der Klimawandel: verstehen und handeln", around 70 participants from all German states gathered in the historic premises of the old central bank. The event was implemented in cooperation with the Wilhelm and Else Heraeus Foundation and Wirkung Hoch 100.
