Greenhouse gas emissions in the U.S. 1990-2022, by inventory sector
Energy-related activities in the United States produced 5.2 billion metric tons of carbon dioxide equivalent (GtCO₂e) in 2022. This accounted for roughly 82 percent of total gross greenhouse gas emissions in the U.S. that year. Energy-related emissions primarily stem from direct emissions associated with fuel use and fugitive emissions from fossil fuel production.
