The Global Covenant of Mayors for Climate and Energy is a global alliance of cities and local governments voluntarily committed to fight against climate change, reducing its inevitable impacts and facilitating access to a sustainable and affordable energy for all.

“If we want to achieve the objectives we have set for ourselves, we must work together at every level, locally and globally. In this sense, the Global Covenant of Mayors is an excellent platform to allow mayors all around the world to connect, share and innovate so that we can find the best solutions to slow or even reverse the global trend.”

The Global Covenant of Mayors for Climate and Energy (GCoM) empowers mayors, enabling them to share their voice and ideas internationally and actively contribute to the global dialogue on climate change.

Around the world we are already more than 13,000 cities united in our commitment to the fight against climate change. Join the force for change, where global leaders connect, collaborate, and amplify their influence in the worldwide movement towards a sustainable future.

The Global Covenant of Mayors in Canada is a collaboration between the Federation of Canadian Municipalities, ICLEI Canada, C40 Cities, Carbon Disclosure Project (CDP) and the Global Covenant of Mayors Secretariat.

The initiative combines two leading domestic climate programs, the Partners for Climate Protection (PCP) program and Building Adaptive and Resilient Communities (BARC).

“The Global Covenant of Mayors is an ideal way for Guelph to connect with other cities, share data and metrics, and find solutions to common problems such as climate change.”


The Global Covenant of Mayors for Climate and Energy (GCoM) is the largest global alliance of mayors and local authorities, with more than 13.200 cities engaged in more than 144 countries around the world. Commitment to the Global Covenant of Mayors for Climate and Energy means a commitment not only to take bold local action, but also to work side by side with peers around the world to share innovative solutions that allow mayors to do more and faster. GCoM cities and local governments connect, exchange, learn, and share with each other.



The Global Covenant of Mayors for Climate and Energy (GCoM) will address three key issues: climate change mitigation, adaptation to the adverse effects of climate change and universal access to safe, clean and affordable energy.


Climate change mitigation refers to the adoption of measures aimed at accelerating the decarbonization of the atmosphere and reducing the impact produced by humanity on the climate and the environment.


Adaptation to climate change refers to actions taken to make society more resilient to the environmental degradation that is already occurring, so that it degrades less and less.


Guaranteeing universal access to energy is essential, but it goes further. Access to energy must be universal, and this in turn must be safe, clean and affordable.

The Global Covenant of Mayors for Climate and Energy (GCoM) in Canada receives financial support from the European Union. Aligned with the European Green Deal and the objectives outlined in the Paris Agreement, this collaboration reflects the EU’s commitment to drive a fair and sustainable climate transition. Supported by the European Union, the GCoM in Canada strengthens the commitment of canadian cities to climate action, providing crucial resources to address environmental challenges and accelerate the path towards a more resilient and ecological future in the region.
