The German energy transition impacts neighbouring countries; however this fact has yet to be adequately addressed in Germany. This study builds on insights gained during trilateral meetings and provides information and analyses which explain the different approaches and debates in the Czech Republic, Germany, and Poland. The authors – among them Dr. Camilla Bausch and Sascha Müller-Kraenner from Ecologic Institute – offer a range of recommendations, in particular for better cross-border cooperation and intensified dialogue with the goal of facing our energy and climate challenges together.
