Federal Constitutional Court orders a tighter German climate path
On 29 April 2021 the Federal Constitutional Court held that the 2019 Climate Action Act insufficiently protected future freedom by back-loading cuts. The judgment is a constitutional check on her last climate statute. In the causal graph this event weakens Decarbonization and climate-mitigation policy, a driver that weakens Global CO2 emissions per capita — a worsening welfare path.
