The 2018 Summit will bring together leaders from state, tribal, and local governments, business, and citizens from around the world, to demonstrate how the tide has turned in the race against climate change, showcase climate action taking place around the world, and inspire deeper commitments from each other and from national governments — 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
