"One of the largest and most developed countries in the world, the United States is also one of the worst polluters globally. The U.S. remains one of the world's top greenhouse gas emitters - currently behind China and India in total annual emissions - but it continues to lead all nations except China in cumulative historical output. According to the Environmental Protection Agency, U.S. greenhouse gas emissions were about 6.34 billion metric tons of CO₂-equivalent in 2022, and 2023 data showed a modest decline."
"Coal-fired power generation in the U.S. fell by roughly 47% between 2014 and 2023, from 1.58 billion megawatt-hours in 2014 to 828 million megawatt-hours in 2023. Over the same period, electricity production from wind and solar farms nearly tripled, rising from about 200 million MWh in 2014 to roughly 660 million MWh in 2023. The shift has had a meaningful impact, as emissions from electric power generation have fallen by roughly one-third in the U.S. since 2014, according to the U.S. Energy Information Administration."
The United States is a leading global greenhouse gas emitter and ranks high in cumulative historical emissions. U.S. greenhouse gas emissions were about 6.34 billion metric tons CO₂-equivalent in 2022, with a modest decline in 2023. Electricity generation accounted for roughly 22% of emissions in 2023, down from 25% in 2022 as coal usage declined. Coal-fired power generation fell about 47% from 2014 to 2023 while wind and solar production nearly tripled in the same period. Emissions from electric power generation have fallen roughly one-third since 2014. Federal decarbonization goals depend on extensive cooperation from states, which vary in policy due to differing climates, geographies, and resources.
