- Power plants were the largest stationary source of U.S. greenhouse gas emissions, with 1,320 facilities emitting approximately 1.5 billion metric tons of carbon dioxide. Reported power plant emissions decreased by 7.2%. There is a 33.8% decrease in emissions since 2011 reflecting the long-term shifts in power sector fuel-stock from coal to natural gas.
- Petroleum and natural gas systems were the second largest stationary source of reported emissions, reporting 322 million metric tons of greenhouse gas emissions. Reported emissions for 2023 were 1.4% higher than in 2022, and 16.4% higher than 2016. (2016 is the earliest year of comparable data for this sector, as new industry segments began reporting that year.)
- Reported direct emissions from other large sources in the industrial and waste sectors were a combined 785 million metric tons of greenhouse gas emissions in 2023, down 1.1% from 2022, and down 10.3% since 2011.
- From 2011 to 2023, total reported GHG emissions from large facilities decreased by approximately 22%, driven by a decrease in power plant emissions.
