Post-COP21, Cities Show Renewed Purpose and Stronger Commitment

By Mark Watts, Executive Director of C40 Cities Climate Leadership Group

On December 4th, more than 1,000 mayors, local representatives and community leaders took part in the Climate Summit for Local Leaders convened by Paris Mayor Anne Hidalgo and U.N. Secretary-General’s Special Envoy for Cities and Climate Change Michael Bloomberg. This largest gathering of elected local leaders on climate change ever, showcased successful city climate action with the international community, and added to the growing momentum for a meaningful global climate agreement.

COP21 was a great success for climate diplomacy: The Paris Agreement, adopted by 195 UNFCCC member States, is a major breakthrough that creates the chance to avoid the most severe impacts of climate change. The reference to pursuing efforts to limit temperature increase to 1.5 degrees Celsius is the strongest acknowledgement yet of the seriousness of the problem. It should be the start of a new climate economy – a critical chance to advance a new era of better, stronger, more equitable growth.

Moving forward, implementing the Paris Agreement will require unprecedented cooperation among multiple actors – and a groundswell of political support from citizens. As Mike Bloomberg says in the video clip below, “If the public understands the problem and the public demands a solution to the problem, then governments around the world will do something about it.”
