The Climate Action Monitor is the OECD's data-driven webbook on climate change. It provides an integrated overview of emission trends, climate-related hazards and relevant policy developments across OECD members and partner countries. Drawing on official data, it provides a common evidence base for understanding current trends, assessing progress and identifying remaining challenges in climate action.
This edition examines countries' emissions and national targets. It also assesses trends in climate-related hazards and their impacts.
A core objective of the Climate Action Monitor is to strengthen the evidence base for decision-making. It enables countries to assess progress towards their national targets, better understand exposure to extreme weather events at national and subnational levels, and compare the development of climate policies across sectors. The webbook provides transparent, comparable and reliable information to support informed policy discussions.
