On March 4, 2020, the European Commission delivered the first major climate piece of its European Green Deal: it proposed a “European Climate Law,” which takes the form of a Regulation and establishes a framework for the irreversible and gradual reduction of greenhouse gas emissions and the enhancement of removals in the European Union. The proposal and the fact that it takes the form of a binding Regulation may have a significant impact on a wide variety of legislative and policy initiatives that the EU and its Member States may take within the next years.
