Data source: Carbon factors provided by the U.S. Environmental Protection Agency, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2022, Tables A-20, A-25, A-32, and A-226 ^aExcludes fuel ethanol blended into motor gasoline. The fuel ethanol component of finished motor gasoline is treated as nonemissive. See methodology documentation for further details on calculations. ^bCarbon factors for municipal solid waste, tire-derived fuel, and waste oil are provided by the U.S. Environmental Protection Agency, Greenhouse Gas Emissions Factor Hub ^cThe carbon factor for municipal solid waste has been adjusted to apply both to biogenic and non-biogenic waste Note: To convert to carbon equivalents multiply by 12/44. Coefficients may vary slightly with estimation method and across time. Coefficients are based on data from 2022. EIA uses these coefficients for estimating 2023, and more recent, energy-related CO₂ emissions.
