Germany enacts the Climate Action Act
In December 2019 the Climate Action Act set sectoral carbon budgets and a 2030 reduction path. A later Constitutional Court ruling forced a tightening in 2021. In the causal graph this event strengthens Decarbonization and climate-mitigation policy, a driver that weakens Global CO2 emissions per capita — an improving welfare path.
