Climate change, sustainability, and competition law

Abstract Climate Change is an existential threat. Competition law must be part of the solution and not part of the problem. This article draws on the constitutional provisions of the EU treaties and remarks by leaders such as Commissioner Vestager to show how competition law need not stand in the way of urgent action and co-operation by the private sector to fight climate change. It also shows how sustainability is relevant to both the analysis of mergers and dominance cases. It is a call to update our thinking, our guidelines and, if necessary, our law. Based on EU law it contains ideas that could inspire changes in other jurisdictions.
