The World is Watching Cities, Now More than Ever

COP21 brought cities into the spotlight. C40 is proud to help shine that light a little brighter. Because cities and mayors are acting now, and we're right beside them as they become necessary leaders in this vital cause.

As the world moves forward from Paris, we're showcasing stories that help explain why cities are so critically important for implementing on the goals set forth in that historic accord. C40's road from Paris moved through member cities Beijing for the Second China-U.S. Climate-Smart Low-Carbon Cities Summit; Singapore for the World Cities Summit; Quito for Habitat III; and now culminates in Mexico City for the sixth biennial C40 Mayors Summit and C40 Cities Awards

What We're Working On

C40 launched a series of new partnerships and programmes at this year's summit, and our Mayors made new commitments to advance the pace of bold climate action.

The sixth biennial Mayors Summit, C40’s flagship event, ushered in the organization's most ambitious slate of announcements. From urban waterfront redevelopment to eliminating diesel vehicles, C40 Mayors helped advance a shared agenda through collaboration, knowledge sharing, and increased visibility of climate actions in cities.

Learn more about our latest programme, C40 Inclusive Cities, by watching the film above. This new programme will complement existing C40 efforts to help ensure climate action also creates greater social equity and sustainable cities for all.
