Since the 2017 federal elections, Alliance 90/The Greens (Bündnis 90/Die Grünen) have increased the number of their governmental participations in the Länder on a high level. In Hesse, Bremen, Thuringia and Hamburg they were able to continue four coalitions in identical or slightly adjusted constellations.

Questions of environmental and climate policy remain relevant even during a pandemic, as the protests and debates about the stimulus package to fight the crisis show.  The German states have taken on a deciding roll regarding questions of implementation – which started already during the negotiations for the climate package. The Greens contributed the most to the climate package's increased substance.
