Secretary Kerry builds support for a strong agreement that's designed to ladder up ambition over time

“Doubling the US commitment to adaptation finance is equitable and fair. With this announcement, Secretary Kerry builds support for a strong agreement that’s designed to ladder up ambition over time. Transparency, no double counting of reductions, and stock-taking every five years are the essential elements. We can’t leave Paris without a credible framework to ratchet up the ambition—and the sooner all countries, including the United States, come back to the table, the more likely they are to step up their game.”
