The Global Covenant of Mayors for Climate & Energy

The Global Covenant of Mayors for Climate & Energy (GCoM) is the largest global alliance of cities and local governments committed to ambitious climate and energy action. With over 9,000 members representing more than 1.2 billion people, GCoM supports local leaders in delivering measurable, science-based solutions to reduce emissions, build resilience, and ensure equitable access to clean energy.

GCoM focuses on three pillars: climate mitigation, climate adaptation, and access to affordable, reliable, and sustainable energy. The alliance helps local governments develop emissions inventories, set targets, create integrated climate action plans, and report progress through recognized platforms such as CDP-ICLEI Track.

How it works

ICLEI is a founding partner of GCoM and plays a key role in shaping and delivering the alliance's work through its carbonn Climate Center. The carbonn Climate Center helps ensure that GCoM commitments translate into real progress. Cities and regions looking to align with global climate goals, strengthen local climate plans, and access support are encouraged to join GCoM through ICLEI’s network.

The Center supports GCoM by:

Providing strategic input to guide the organization's long-term planning in alignment with ICLEI’s five development pathways
Contributing technical expertise through participation in key technical working groups, including leadership on climate finance
Supporting cities in reporting through CDP-ICLEI Track, ensuring consistency and alignment with global climate goals
Reviewing local climate action plans for compliance with the Paris Agreement and offering tailored guidance on next steps
Contributing to the CHAMP working group, with targeted engagement in Bangladesh and Canada to support multilevel climate action

Any city or town in the world can commit to the Global Covenant of Mayors for Climate & Energy, regardless of size or location. Cities or local governments that want to formalize a commitment to GCoM should submit a commitment document, which must be signed by an appropriately mandated official according to local governmental procedures.
