The transportation sector is one of the largest contributors to anthropogenic U.S. greenhouse gas (GHG) emissions. According to the Inventory of U.S. Greenhouse Gas Emissions and Sinks 1990–2020 (the national inventory that the U.S. prepares annually under the United Nations Framework Convention on Climate Change), transportation accounted for the largest portion (27%) of total U.S. GHG emissions in 2020. Cars, trucks, commercial aircraft, and railroads, among other sources, all contribute to transportation end-use sector emissions.
