C40’s Climate Action Planning programme supports cities around the world to create and implement climate action plans in line with the 1.5°C target of the Paris Agreement.
C40 high-impact declarations are statements of political leadership by mayors from around the world. They are based on the most ambitious, science-based targets and lay out concrete delivery milestones, both for mitigation and adaptation.
Learn about all of the declarations and check the latest C40 declaration progress reports below.
In the midst of climate breakdown, mayors are facing multiple interlinked crises, including the COVID-19 pandemic and persisting social injustices. A Global Green New Deal with inclusive climate action at its heart is needed to build thriving communities that work for everyone.
C40 provides research, analysis, implementation guides and more to support and empower cities to transition towards a green and just economy where everyone, everywhere, can thrive.
