World leaders are focused on continued efforts to decarbonize their individual economies, and, in turn, the global economy. These efforts are making the 2020s the “decade of decarbonization” and a critical inflection point for the world’s emissions. This EPRI report, prepared for the 2021 United Nations Climate Change Conference (COP26), looks at 11 countries and examines their respective greenhouse gas (GHG) emission targets in the Paris Agreement, their different GHG starting points, trends in historical and future GHG emissions, emission targets pre- and post-2018, and their sources of electric consumption. The brief closes with a review of key EPRI decarbonization research.
