A powerful and historic movement
When cities engage in the Global Covenant of Mayors, they demonstrate their leadership, setting an example for cities all over the world to become part of the global solution to climate change. Cities that join the GCoM pledge to develop a greenhouse gas emissions inventory and assessment of climate risks, and set measurable emissions targets, ambitious climate adaptation goals, and sustainable energy access goals in line with the Paris Agreement. Signatories agree to formally adopt plans and targets with three years of making a commitment.
Leading by example
By committing to the Global Covenant of Mayors, cities and local governments increase their visibility as leaders responding to climate change and demonstrate their commitment to an ambitious global climate solution. GCoM helps cities in achieving their ambition by supporting the collaboration and sharing of best practices among peers around the world, providing, technical and financial capacity-building and training activities, and generating the next generation of knowledge, data, tools needed for local policymakers to tackle sustainability and climate challenges.
With support from local and global partners
Joining the Global Covenant of Mayors engages cities in a far-reaching global alliance supported by 100+ partners. A commitment demonstrates to the world that your city is joining among a distinguished group of leaders with an alliance to support you with training, tools, and resources, while also promoting climate leadership through communications campaigns and city profiles.
How to join us
We welcome any city or town in the world to 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.

The Common Reporting Framework (CRF)
The Common Reporting Framework (CRF) guides cities in assessing their greenhouse gas emissions, climate change risks, and vulnerabilities, as well as planning and reporting in an integrated and coherent way. This standard not only enables cities to identify and take the right actions in a timely manner, but also allows for better identification of shared challenges, greater cooperation, and development of common responses to the impacts of climate change.
