Why cities matter

Cities contain more than half of the world’s population, and they consume more than two-thirds of the world’s energy. Local leaders across the globe are pursuing ambitious climate initiatives in their communities. They are key to delivering on the Paris Agreement. All levels of government – cities, regions, and nations – have a role to play when it comes to raising the bar and working hand-in-hand with the scientific community, financial institutions, and the private sector. Only through dynamic, multi-level collaboration can we reach a net-zero-emission world by 2050. This joint effort is historic – and together, we are unstoppable.

We welcome cities worldwide

We encourage any city or town to commit. Regardless of size or location, all cities are welcome to join the alliance at any time of the year.
