Feb 12 -- The Draft Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2019 is available for public review. The Environmental Protection Agency (EPA) requests recommendations for improving the overall quality of the inventory report to be finalized in April 2021, as well as subsequent inventory reports. To ensure your comments are considered for the final version of the document, please submit your comments by March 15, 2021. However, comments received after that date will still be welcomed and considered for the next edition of this report.
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 (N2 O), 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: 1990-2019 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.
