In far-flung corners of the federal government, staffers have been busy calculating how quickly the United States could embrace electric cars or phase out the last of the nation’s coal-fired power plants. They are estimating how fast the country can construct new battery-charging stations and wind turbines, as well as how farmers can store more carbon in the soil — and how much Congress might allocate to fund such efforts. They’re urgently trying to tally up the elements of a major promise, one that could shape how aggressively the world takes on climate change. By April 22, when President Biden convenes world leaders for an Earth Day summit, he is expected to unveil a new, aggressive plan to cut U.S. greenhouse gas emissions between now and 2030.
