Abstract

The Draft Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 is available for public review. This docket is associated with that notice of document availability and request for comments. Annual U.S. emissions for the period of time from 1990 through 2021 are summarized and presented by source category and sector. The inventory contains estimates of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) emissions. The technical approach used in this report to estimate emissions and sinks for greenhouse gases is consistent with the methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC) and reported in a format consistent with the United Nations Framework Convention on Climate Change (UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 is the latest in a series of annual, policy-neutral U.S. submissions to the Secretariat of the UNFCCC. EPA requests recommendations for improving the overall quality of the inventory report to be finalized in April 2023, as well as subsequent inventory reports.
