There is some very good news on the climate front. Every US state reduced per capita carbon dioxide emissions from primary energy consumption between 2005 and 2023. The US Energy Information Administration (EIA) recently released data indicating that total US CO2 emissions fell by 20% over the period, even as population rose by 14%. The result is a 30% decrease in per capita CO2 emissions.
