In-brief analysis
September 15, 2025
Per capita CO2 emissions from primary energy consumption decreased in every state from 2005 to 2023, according to recently released data in our State Energy Data System. Total energy-related CO2 emissions in the United States fell 20% over that time, and the population grew by 14%, leading to a 30% decrease in per capita CO2 emissions.
CO2 emissions across the country primarily declined because less coal was burned in the electric power sector. Increased electricity generation from natural gas, which releases about half as many CO2 emissions per unit of energy when combusted as coal, and from non-CO2-emitting wind and solar generation offset the decrease in coal generation. Looking ahead, our Short-Term Energy Outlook forecasts a slight 1% increase in U.S. total CO2 emissions in 2025, in part because of more recent
