How local governments, the private sector, and civil society can help countries implement climate action and step up ambition in 2018 and beyond.
2018 launches an international effort to enhance climate action and ambition by 2020, the first “ratchet” since the Paris Agreement. Cities, states and regions, business, investors, civil society groups, and other “non-Party actors” play a critical role in this process by delivering progress on the ground and in the real economy. But they also generate new opportunities for national governments to strengthen implementation and step up ambition. Focusing on this mutual reinforcement, this memo explains how non-Party actors can support countries to step up action and ambition in 2018, while also looking forward to 2020.
