[A "Smooth Achievement" in Carbon Emissions? The Truth Behind the Data and Future Challenges] ⑴ Data from the U.S. Energy Information Administration (EIA) show that per capita CO2 emissions in every U.S. state declined from 2005 to 2023. ⑵ Over the same period, total energy-related CO2 emissions in the United States fell by 20%, while the population grew by 14%, resulting in a 30% reduction in per capita emissions. ⑶ This significant decrease is primarily due to a reduction in coal combustion in the power sector. ⑷ Specifically, increases in natural gas power generation and non-CO2-emitting power generation such as wind and solar effectively offset the decline in coal-fired power generation. ⑸ However, the EIA forecasts a 1% increase in total U.S. CO2 emissions in 2025. ⑹ This increase is partially due to recent increases in fossil fuel consumption in crude oil production and growth in power generation. ⑺ Despite the significant decline in per capita emissions, total emissions face the risk of a rebound in 2025, demonstrating that controlling total emissions requires continued attention during the energy transition.
