Today, the world’s two primary city-led climate change and energy initiatives, the EU Covenant of Mayors and the Compact of Mayors, announced the formation of a new, first-of-its-kind global initiative of cities and local governments leading in the fight against climate change. This single initiative will create the largest global coalition of cities committed to climate leadership, building on the commitments of more than 7,100 cities from 119 countries and six continents, representing more than 600 million inhabitants, over 8% of the world’s population.

The launch of the Global Covenant of Mayors for Climate & Energy comes six months after the historic Paris climate change conference, where cities were crucial voices in shaping and advocating for a strong global agreement, and is a historic and powerful response by the world’s local leaders to the urgent climate challenge.

The Covenant of Mayors was launched in 2008 by the European Union after the adoption of the 2020 European Union Climate and Energy Package. The Compact of Mayors was launched in September 2014 by UN Secretary-General Ban Ki-moon, UN Secretary-General’s Special Envoy for Cities and Climate Change Michael R. Bloomberg and mayors from global city networks C40, ICLEI and UCLG. Both initiatives have supported participating local governments in setting ambitious climate reduction goals, taking ambitious action to meet those objectives, and measuring their progress publicly and transparently.

“Today, the world’s cities are uniting their efforts to fight climate change behind a single global organization, something that has never before happened," said UN Secretary-General’s Special Envoy for Cities and Climate Change Michael R. Bloomberg, who will Co-Chair the new Global Covenant of Mayors for Climate & Energy. “In unity there is strength, and this new Global Covenant of Mayors for Climate & Energy will help accelerate the progress cities are making and magnify their influence on the global stage. This is a giant step forward in the work of achieving the goals that nations agreed to in Paris."

The new Global Covenant of Mayors for Climate & Energy will be the world’s largest coalition of mayors promoting and supporting voluntary action to combat climate change and move to a low-carbon economy.

By aligning city-led efforts, the Global Covenant of Mayors for Climate & Energy will allow for greater collaboration between cities across the world, bridging gaps and building connections, as well as increasing funding to support and empower city action on sustainable energy and climate change. This merger will harness the convening and investment powers of the European Union and Bloomberg Philanthropies, as well as the critical global city network partners of each initiative, including C40, ICLEI, UCLG, Eurocities, Energy Cities and Climate Alliance – allowing for a stronger presence and visibility of local authorities in the on-going work of the UN Framework Convention on Climate Change.
