SkyShares: An Idea to Stop Climate Change Effectively, Efficiently, and Equitably

At COP25 this week, parties to the United Nations Framework Convention on Climate Change (UNFCCC) will determine a path forward for emission reductions. In 2020, countries are expected to make big changes to their emission reduction strategies. And four years ago, ahead of COP21, CGD’s Owen Barder, Alex Evans, and Alice Lépissier laid out a framework called “SkyShares” that would lock in emissions reductions at the lowest possible cost, and support developing countries’ efforts to eradicate poverty.
