-----------------------------------------------------------------------

SUMMARY: The Draft Inventory of U.S. Greenhouse Gas Emissions and 
Sinks: 1990-2019 is available for public review. The Environmental

overall quality of the inventory report to be finalized in April 2021, 
as well as subsequent inventory reports.

SUPPLEMENTARY INFORMATION: Annual U.S. emissions for the period of time 
from 1990 through 2019 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

[[Page 9340]]

consistent with the United Nations Framework Convention on Climate 
Change (UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse 
Gas Emissions and Sinks: 1990-2019 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 2021, as well as subsequent 
inventory reports. The draft report is available at https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks.
