About the Global Covenant of Mayors for Climate & Energy 

The Global Covenant of Mayors for Climate & Energy (GCoM) is an international alliance of cities and local governments with a shared long-term vision of promoting and supporting voluntary action to combat climate change and move to a low emission, resilient society.

Formally bringing together the European Union Covenant of Mayors and the Compact of Mayors, GCoM builds on the commitments of over 7,400 cities and local governments from six continents and 121 countries representing more than 600 million residents. 

ICLEI is a founding parter of GCoM, offering technical, policy and advocacy expertise to serve local governments. As the focal point of the Local Governments and Municipal Authorities (LGMA) constituency to the United Nations Framework Convention on Climate Change (UNFCCC), ICLEI represents the collective voice of local and regional governments at the international climate negotiations, ensuring the joint efforts of GCoM partners and committed cities are recognized.  

How to commit

Any city or town in the world can commit to GCoM – regardless of size or location. Cities or local governments that want to formalize a commitment need to submit a commitment text signed by an appropriately mandated official, such as the mayor or city council. Committed cities then begin the process towards achieving compliance with GCoM standards with support from ICLEI and other GCoM partners.

Reporting to GCoM

The carbonn Climate Registry (cCR) and the CDP are both recognized reporting platforms for local governments committed to GCoM, which means data reported will feed into analyses of the aggregate impact of committed cities.

The cCR is open for voluntary reporting to all levels of governments, from towns and cities to states, regions and provinces. The cCR has been designed to support and facilitate vertical integration, encouraging local governments within the same geographic region to report, also ensuring that data is not double-counted when aggregated.

The cCR is managed by the Bonn Center for Local Climate Action and Reporting - the carbonn Center - based in Bonn, Germany, hosted by the ICLEI World Secretariat.
