EIA: CO2 fell in every state since 2005

7d 1 source

The U.S. Energy Information Administration reports energy-related CO2 emissions per capita declined in every U.S. state from 2005 to 2023, down 30% nationally, with absolute emissions falling 20% as population grew 14%. EIA attributes the drop mainly to a sharp reduction in coal-fired power offset by more natural gas and rising wind and solar, and it projects a roughly 1% increase in overall CO2 emissions in 2025 as data centers and heavy industry boost electricity demand.
