Global Covenant of Mayors for Climate and Energy (GCoM), based in Brussels, is a nonprofit that coordinates a global network of cities and local governments focused on climate and energy action. It mobilizes and supports ambitious, measurable plans at the community level through collaboration with city and regional networks, national governments, and other partners to advance a resilient, low-emission society. The organization is led by Michael R. Bloomberg, in his capacity as UN Special Envoy on Climate Ambition and Solutions, together with the European Commission, and its coalition spans six continents and 144 countries, representing more than one billion people. Its primary customers are cities and local governments seeking to implement climate and energy actions. The alliance serves as a conduit that connects cities with regional networks, national authorities, and other partners to turn climate ambition into concrete plans and actions. A recent development is the May 2026 partnership with the European Commission to advance collaborative climate initiatives.
