This Yearbook of Global Climate Action, the sixth of the series, reviews the state and scope of global climate action in 2022. It outlines what is needed to accelerate sectoral systems transformation, features case studies of real-world climate action projects, highlights some key global climate action topics – particularly regionalization and accountability – and presents the High-Level Champions’ contribution to these issues. It also highlights what needs to be achieved in 2023, particularly with regard to the Global Stocktake and the work being done on implementing the improved Marrakech Partnership.
