American CO2 Emissions Down 17.2% 2005 As Coal Falters, But Decline Far Too Slow For 2030 Goals

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.

Still, the decline in emissions to date hasn’t been nearly steep enough to meet the nation’s goals for trying to slow global warming. President Biden wants to reduce America’s greenhouse gas emissions at least 50 percent below 2005 levels by 2030. To hit that goal, annual emissions would have to fall more than three times as fast for the rest of the decade as they did last year, the report found.

The researchers looked at planet-warming emissions generated by transportation, electricity, industry and buildings but did not include pollution from agriculture, which accounts for roughly 10 percent of the nation’s greenhouse gases.
