Momentum continues to grow around the world for strong climate action. In 2015, world leaders reached a historic climate agreement in Paris. Last month, 175 leaders signed the agreement on Earth Day in New York, breaking a world record for the number of countries to sign an international agreement in one day. Now, as we move forward, multi-sector leaders have come together at Climate Action 2016 to discuss how we can capitalize on this momentum to set the world on a sustainable path.
