The EU is committed to achieving climate neutrality by 2050 at the latest. To meet this objective, the European Climate Law requires the EU to adopt an intermediate greenhouse gas target for 2040. It mandates the European Commission to propose such a target, accompanied by a projected indicative EU greenhouse gas budget for the 2030-2050 period. These should be based on the best available and most relevant scientific evidence, and take into account the advice of the European Scientific Advisory Board on Climate Change.
