About us
GCoM is the largest global alliance for city climate leadership, uniting a global coalition of over 12,500 cities and local governments and 100+ supporting partners. The cities and partners of GCoM share a long-term vision of supporting voluntary action to combat climate change and towards a resilient and low-emission society. GCoM serves cities and local governments by mobilizing and supporting ambitious, measurable, planned climate and energy action in their communities by working with city/regional networks, national governments, and other partners to achieve our vision. Led today by UN Special Envoy on Climate Ambition and Solutions Michael R. Bloomberg and European Commission Executive Vice President Frans Timmermans, the coalition comprises cities across six continents and 142 countries, representing over one billion people or more than 13% of the global population.
