This chapter examines the European Union's external environmental policy, with particular emphasis on the challenge faced by the EU in exercising leadership in global environmental governance and in the development of the climate change regime. It first considers the international dimension of the EU environmental policy as well as the issue of sustainable development before discussing the EU's efforts to lead the negotiation of an international climate regime up until the 2015 Paris conference. It then explores how the different energy interests of the member states have been accommodated in order to sustain European credibility. It also looks at the question of climate and energy security in the EU and concludes with an assessment of the factors that determine the success or failure of the EU in climate diplomacy, including those that relate to coordination and competence problems peculiar to the EU as a climate negotiator.
