The question of how best to tackle anthropogenic climate change is a thorny one: besides scientific uncertainty regarding the consequences of climate change, another difficulty is that the recommendations of climate experts may clash with the priorities of citizens, interest groups and political institutions. With the European Green Deal, the European Union (EU) recently made significant advances in climate policy; at the same time, and as is well known, the EU and its institutions have long been criticised for their “democratic deficit” and for their failure to involve all civil society actors equally in EU law-making processes. This article sheds light on the legal framework governing civil society participation in EU law-making, and more specifically on the Commission’s consultations pursuant to Article 11(3) of the Treaty on European Union. It then critically assesses selected features of two consultations conducted by the Commission in connection with the European Climate Law, which it evaluates from the perspective of the EU primary law principles of democracy, openness and transparency. Through this analysis, and by suggesting how future climate consultations could be further improved, the article aims to contribute to the (still nascent) legal scholarship on civil society participation in environmental and climate policy.
