In November 2019 the European Parliament (2019/2930(RSP)) declared a climate and environmental emergency, calling for urgent and concrete action. The year 2019 was Europe's hottest year on record (Copernicus Climate Change Service, 2019), and the Intergovernmental Panel on Climate Change (2018, p. v) reported that 'emissions of greenhouse gases due to human activities, the root cause of global warming, continue to increase, year after year'. Swedish teenage climate activist Greta Thunberg inspired and led a worldwide school strike movement, and mass protests dominated by young women took place around the world (Wahlström et al., 2019). The European Parliament resolution of 14 March 2019 (2019/2582(RSP)) 'welcomes the fact that people across Europe, in particular younger generations, are becoming increasingly active in demonstrating for climate justice'. At the institutional level 2019 was a year of renewal, with the European Parliament elections in May, the adoption of a new Council strategy in June and the appointment of a new Commission in December. Climate change was a priority for all these institutional actors. The Council strategy 2019-24, for example, insists on the urgent need to build a 'climate-neutral, green, fair and social Europe'. The new President of the Commission Ursula von der Leyen announced her intention to see Europe become the first climate-neutral continent by 2050. Climate change arrived on the EU agenda in the 1980s, emerging out of environmental policy, which was already established as an area that required transnational action. Throughout the 1990s and early 2000s the climate ambition of the EU exceeded its ability to agree on, and implement, effective actions (Dupont and Oberthür, 2015). When the USA withdrew from the Kyoto protocol in 2001 the EU took on a global leadership role and has continued to construct an identity as a global actor around the issue of climate change (Jordan et al., 2010). This had economic motivations (to avoid being undercut by exporters with lower environmental standards) but was also part of the post-Maastricht efforts to increase the EU's global actorness. The past decade has seen climate change gain prominence and take centre stage. In 2009 the landmark climate and energy framework (COM(2014)15 final) introduced targets for greenhouse gas emissions, energy efficiency and renewable energy. Within the European Commission climate action gained its own Directorate General, DG CLIMA. This was an important part of the process of institutionalizing climate change. The issue of climate change continued to rise up the EU and the global agenda, and there was a strong dynamic between the two. The Lisbon Treaty (2007) gave the EU competence to conclude international environmental agreements. The EU, along with its member states, is a party to the United Nations
