TAKING AMBITION TO THE NEXT LEVEL. The 2018 Summit will bring people together from around the world to showcase climate action and inspire deeper commitments from national governments, and each other, in support of the Paris Agreement.

“Come join us – entrepreneurs, singers, musicians, mathematicians, professors, students – we need people that represent the whole world because this is about the whole world and the people who live here … It’s time to act, it’s time to join together, and that’s why at this Climate Action Summit, we’re going to get it done.” –Governor Edmund G. Brown Jr., Message to the Global Citizen Festival in Hamburg, Germany, July 2017
