The C40 World Mayors Summit is C40’s 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, business leaders, global influencers, philanthropists, campaigners, youth leaders, scientists and residents at a key moment ahead of COP27, to demonstrate what a strong global coalition united on radical climate action can achieve.
Mayors will use the Summit to show the progress global cities have made in confronting the climate crisis during the COVID-19 pandemic, highlighting how they are accelerating the delivery of their climate commitments and helping create a more sustainable, equitable world where everyone, everywhere can thrive.
There is no time to waste — we must take faster, fairer, and more ambitious inclusive climate action now.
