At COP26 during the World Leaders Summit Forest Day session on November 2, 2021, the United States announced the Plan to Conserve Global Forests: Critical Carbon Sinks. This decade-long, whole-of-government Plan sets forth the U.S. approach to conserving critical global terrestrial carbon sinks, deploying a range of diplomatic, policy, and financing tools. The first-of-its-kind plan for the U.S. government seeks to catalyze the global effort to conserve and restore the forests and other ecosystems that serve as critical carbon sinks. Subject to Congressional appropriations, by 2030, the United States intends to dedicate up to $9 billion of our international climate funding to support the objectives of the Plan. The United States recognizes that without halting deforestation and restoring forests at scale, we cannot reach net zero emissions by 2050, and we cannot limit warming to 1.5 degrees Celsius. This is not a long-term challenge. It is something we must do immediately, in this critical decade. Forests and other ecosystems could provide as much as one-third of global mitigation by 2030  by reducing emissions from deforestation and forest degradation and by enhancing the carbon sequestered from the atmosphere through forest restoration. The Plan to Conserve Global Forests: Critical Carbon Sinks has been devised to catalyze even more ambitious global action towards this end.
