C40 World Mayors Summit

The C40 World Mayors Summit is the triennial climate action conference organised in partnership with a C40 member city. This year’s Summit, hosted by the City of Buenos Aires from 19–21 October 2022, will be a hybrid in-person and virtual event.

The Summit will bring together mayors of world-leading cities, alongside business leaders, global influencers, philanthropists, campaigners, youth leaders, scientists and residents, to showcase the work cities are doing to deliver effective climate solutions and demonstrate what a strong global coalition united on radical climate action can achieve.

There is no time to waste — we must take faster, fairer, and more ambitious inclusive climate action now.
