The Global Covenant of Mayors for Climate & Energy brings together thousands of local governments voluntarily committed to implementing ambitious climate and energy objectives on their territory. It is a powerful response by cities to address the climate challenge. Building on the commitment of over 9,000 cities, it is the world’s broadest multi-stakeholder alliance committed to local climate leadership. The Global Covenant of Mayors brings together under a single umbrella regional Covenant of Mayors offices located across the globe, each organised along principles and methods that best suit each region. Regional Covenant offices help coordinate and support engagement with participating cities.
