The C40 World Mayors Summit will bring together the mayors of global and regional cities, alongside business leaders, philanthropists, campaigners, youth leaders, scientists and residents, to share bold ideas, showcase innovative solutions and stand together to create a sustainable, prosperous and equitable future.
An active C40 member since 2006 and current member of the C40 Steering Committee representing Latin America, Buenos Aires has committed to halving its carbon emissions by 2030 and going fully carbon neutral by 2050. Its bold and innovative climate solutions can be an inspiration to all.
C40 is a network of mayors of nearly 100 world-leading cities taking urgent action to confront the climate crisis and create a future where everyone can thrive. Representing 582+ million people and one-fifth of the global economy, mayors of C40 cities are on the leading edge of climate action, deploying a science-based and collaborative approach to help the world limit global heating to 1.5°C, and build healthy, equitable and resilient communities.
