SUPPLEMENTARY INFORMATION: Annual U.S. emissions for the period of time
from 1990 through 2021 are summarized and presented by sector,
including source and sink categories. 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. The draft report is available at https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks.

Director, Office of Atmospheric Programs.
