America’s greenhouse gas emissions fell 1.9 percent in 2023, in large part because the burning of coal to produce electricity plummeted to its lowest level in half a century, according to estimates published on Wednesday by the Rhodium Group, a nonpartisan research firm.

The drop means that United States emissions have now fallen roughly 17.2 percent since 2005. There was a huge, anomalous dip in planet-warming pollution at the start of the coronavirus pandemic, when large segments of the economy shut down, followed by a sharp rebound in the following two years once activity resumed. But over the longer term, America’s emissions have been trending downward as power plants and cars have gotten cleaner.

The drop was big, but emissions will need to fall three times as fast for the rest of the decade if the country wants to meet its climate goals.
