Decarbonizing the power sector is critical to reducing greenhouse gas emissions. One enormous challenge is tracking the diverse multilateral initiatives that strive to tackle this problem. The governments behind such initiatives must assess their performance and follow best practices. This policy brief provides an overview of some of the most important initiatives and gives an interim assessment of their performance in the context of geopolitical rivalry and weakened multilateralism. Though a number of initiatives have met their respective goals, overall progress on decarbonizing the power sector has been too slow to curb emissions in line with the Paris Agreement. Insights from effective initiatives could serve it and other multilateral initiatives that address the power sector, including Germany’s Climate Club.
