SUPPLEMENTARY INFORMATION: Annual 

U.S. emissions for the period of time 

from 1990 through 2022 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: 

1990–2022 is the latest in a series of 

annual, policy-neutral U.S. submissions 

to the Secretariat of the UNFCCC and 

the Paris Agreement. EPA requests 

recommendations for improving the 

overall quality of the inventory report to 

be finalized in April 2024, as well as 

subsequent annual inventory reports.
