The C40 World Mayors Summit is our triennial climate action conference organised in partnership with a C40 member city. The 2022 Summit, hosted by the City of Buenos Aires from 19–21 October, was a hybrid in-person and virtual event.
C40’s event at COP26 featured mayors and thought leaders from around the world. It addressed ways to achieve a sustainable and equitable recovery from the pandemic and advance C40’s vision of a green and equitable future.
The C40 World Mayors Summit in Copenhagen gathered a global coalition of leading cities, businesses and residents to showcase the radical and ambitious climate action our planet needs to create the future we want.
