From Copenhagen to Paris, cities and mayors are leading the way on climate action

The world’s leading mayors have doubled climate action since COP15 in Copenhagen, and set an example for cooperative action between nations ahead of COP21.

Today, the C40 Cities Climate Leadership Group (C40) and research partner Arup released Climate Action in Megacities (CAM 3.0), a groundbreaking and definitive assessment of how the world’s leading mayors have taken on the urgent challenge of climate change.

CAM 3.0 presents major new insights into the current status, latest trends and future potential for climate action at the city level. Since the last major COP in Copenhagen, C40 cities have taken 10,000 climate actions – a doubling of actions in just six years – and have committed to reduce their CO2 emissions by 3 Gt CO2 by 2030, equivalent to the annual carbon output of India. Furthermore, decisions taken by global cities to invest in low carbon development over the next 15 years have the potential to avoid locking in a total of 45 Gt of CO2, or eight times the total current annual emissions of the United States.

As the world’s most extensive quantitative study of city climate action, CAM 3.0 documents and analyses these actions, and demonstrates the ability of mayors to share knowledge across geographic, political and economic boundaries. Building on two previous installments of this research, CAM 3.0 demonstrates the crucial role that cities continue to play in addressing climate change, and validates their position as a critical partner to state actors., Indeed, the report provides clear evidence that city leaders across the world are already setting ambitious targets, making commitments and taking action to fight climate change ahead of 2020, when the Paris agreement comes into force.

“We’re in better shape going into Paris than we were going into Copenhagen largely because of the progress cities have made, and C40 cities have helped lead —> Read More
