Coal generation decreased in 2022, but overall U.S. emissions increased

U.S. coal-related CO2 emissions decreased by 7%, or 68 million metric tons (MMmt), in 2022 relative to 2021. This decrease was largely due to an 8% decline in coal-fired power generation because of retiring coal-fired generating capacity. Changes in electricity generation sources decreased the carbon intensity of electricity by 4% in the United States in 2022 as growing natural gas-fired and renewable energy resources and a coal supply shortage contributed to the lower coal-related emissions.
