A U.N. Environment Program report issued last year claimed that to achieve the 2015 Paris Agreement’s warming limit goal of 1.5 0 C, the whole world must now reduce global GHG emissions by 7.6 percent every year from now to 2030, ten years ago governments would have needed to reduce 3.3% per year. If we wait until 2025, the world will need to reduce emissions by 15.5 percent per year. Every day we delay, needed GHG emissions cuts become more extreme, expensive, and difficult to achieve.
