SUPPLEMENTARY INFORMATION: Annual U.S. emissions for the period of time 
from 1990 through 2023 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 Paris 
Agreement and United Nations Framework Convention on Climate Change 
(UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse Gas 
Emissions and Sinks: 1990-2023 is the latest in a series of annual, 
policy-neutral U.S. submissions to the UNFCCC. EPA requests 
recommendations for improving the overall quality of the inventory 
report to be finalized in April 2025, as well as subsequent annual 
inventory reports.
