Compact of Mayors

About the Compact of Mayors

The Compact of Mayors is a global coalition of mayors and city officials committing to reduce local greenhouse gas emissions, enhance resilience to climate change and track their progress publicly. It is an agreement by city networks – and then by their members – to fight climate change in a consistent and complimentary manner to national efforts.

The Compact of Mayors was launched by UN Secretary-General Ban Ki-moon and his Special Envoy for Cities and Climate Change, Michael R. Bloomberg, under the leadership of the world’s global city networks – C40 Cities Climate Leadership Group (C40), ICLEI – Local Governments for Sustainability (ICLEI) and the United Cities and Local Governments (UCLG) –with support from UN-Habitat, the UN’s lead agency on urban issues at the 2014 United Nations Climate Summit.

The Compact provides a space to publicly recognize the impact of cities’ collective actions through standardized measurement of emissions and climate risk, and consistent, public reporting of their efforts.

How to participate

To join the Compact, a city leader must engage in the following four phases over a 3 year period. Each phase has a 2 step process: Mitigation and Adaptation.

Cities have up to three years to fulfill the requirements of Compact compliance, with the support of the Compact’s city networks and endorsing partners. You will receive official Compact of Mayors seals to use in your communication material when your city commits to the Compact of Mayors and when it has achieved compliance.
