For most of the past 30 years, the EU has led the world on climate action. The bloc had the deepest reductions in greenhouse gas emissions under the Kyoto protocol; the first climate laws came from EU member states; the first emissions trading scheme, in 2005; and the Paris agreement in 2015.
At times when other major countries – the US, Japan, Canada, China and India at various points – have stepped back, the EU has often stepped forward. There would be no Paris accord had the bloc not won a key battle at the Durban climate summit in 2011 that paved the way.
