The Global Covenant of Mayors for Climate
& Energy in the Americas

“Local governments are the first to face and suffer the impact of climate change affecting our communities. That’s why it’s important to have the GCoM, the largest alliance of local governments in the world working for climate action, which allows municipalities and local governments, whether large or small, to have a voice and tell the world what we are doing

The Global Covenant of Mayors for Climate & Energy (GCoM) is a robust and historic response to climate change from cities worldwide. It is the largest global alliance for city climate leadership, built upon the commitment of over 13,000 towns and local governments. These cities hail from 6 continents and 144 countries, and in total, they represent more than 1.2 billion peopleWith climate mitigation targets projected to reduce global emissions by 4.1 GtCO₂e in 2050, GCoM cities are already taking action by sharing a long-term vision of supporting voluntary action to combat climate change. Together, we’re working towards a resilient, low-emission society and a just energetic transition.

The Latin American Mayors’ Forum

The Mayors’ Forum is a governance body of the GCoM in Latin America. Established in 2022, it brings together mayors from signatory municipalities of the Global Covenant of Mayors from various countries in the region who stand out for their work and commitment to climate change. The objective of the Forum is to strengthen cities’ voices in the GCoM’s strategy and define priorities in Latin America.
It provides greater visibility to the climate action commitment of GCoM signatory municipalities and strengthens their presence in key regional and global climate agenda events and forums. The members of the Mayors’ Forum contribute to the review of the GCoM’s regional strategy to improve its relevance to municipalities’ realities, promote the activities of the alliance with other cities, and participate in national, regional, and global events of the Global Covenant of Mayors, among other responsibilities.


The EU strongly supports climate action for the Americas through a multifaceted and wide-reaching approach, assisting cities as they transition to a low-carbon, more resource-efficient, and sustainable economy as a part of the efforts to achieve its climate and energy goals in line with the Paris Agreement and the 2030 UN Sustainable Development Goals (SDGs). It partners with regional organizations, governments, and local communities to implement ambitious climate mitigation and adaptation strategies. The EU’s contributions are pivotal in advancing the region’s climate resilience agenda, from financing renewable energy projects to promoting sustainable land management practices.

The Global Covenant of Mayors for Climate & Energy (GCoM) is one important initiative funded by the European Union in the Americas.
