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.
