    Following the historic climate deal agreed upon at COP21 in Paris, C40 Cities Climate Leadership Group (C40) has today launched new research highlighting the wide range of economic and social benefits arising from city climate action. With cities setting the pace and scope of climate action until the COP21 agreement comes into force in 2020, the research is intended to help mayors and city leaders win the political argument for taking urgent and ambitious climate action

As urban societies continue to expand and change, so too do the challenges facing them, particularly when it comes to climate change. This growing urban population is vulnerable to the impacts of climate change – for example, 90% of all urban areas are coastal – but it is also powerful.
