About

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. The Compact establishes a common platform to capture the impact of cities’ collective actions through standardized measurement of emissions and climate risk, and consistent, public reporting of their efforts. Through the Compact, cities are:

  • Increasing their visibility as leaders responding to climate change;
  • Demonstrating their commitment to an ambitious global climate solution, particularly as nations convene around a new climate agreement in Paris in December 2015;
  • Encouraging direct public and private sector investments in cities by meeting transparent standards that are similar to those followed by national governments;
  • Building a consistent and robust body of data on the impact of city action; and
  • Accelerating more ambitious, collaborative, and sustainable local climate action.

Ultimately, the Compact of Mayors provides hard evidence that cities are true climate leaders, and that local action can have a significant global impact.
