Inventory of U.S. Greenhouse Gas Emissions and Sinks
Public Review of Draft U.S. Inventory of Greenhouse Gas Emissions and Sinks: 1990-2022
Per an announcement in the Federal Register (FR) FRL-9448-03-OAR, the Draft Inventory of U.S. Greenhouse Gas (GHG) Emissions and Sinks: 1990-2022 is now available for public comment. To ensure your comments are considered for the final version of the document, please submit your comments by March 15, 2024. Learn more about the draft report and how to submit comments.
About the Inventory of Greenhouse Gas Emissions and Sinks
EPA develops an annual report, called the Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory), that tracks U.S. greenhouse gas emissions and sinks by source, economic sector, and greenhouse gas going back to 1990. EPA has prepared the Inventory of U.S. Greenhouse Gas Emissions and Sinks since the early 1990s. This annual report, provides a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States, including carbon dioxide removal from the atmosphere by “sinks,” (e.g., through the uptake of carbon and storage in forests, vegetation, and soils) from management of lands in their current use or as lands are converted to other uses. The gases covered by the Inventory include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. Each year since the early 1990s, EPA publishes the draft report in February to allow for public comment prior to publishing the final report by April 15 of this year.
The national greenhouse gas inventory is submitted under the Paris Agreement and the United Nations Framework Convention on Climate Change. In preparing the annual emissions and sinks inventory report, EPA collaborates with hundreds of experts representing more than a dozen U.S. government agencies, academic institutions, industry associations, consultants and environmental organizations. EPA also collects greenhouse gas emissions data from individual facilities and suppliers of certain fossil fuels and industrial gases through the Greenhouse Gas Reporting Program.
Key findings from the Draft 1990-2022 U.S. Inventory include:
- In 2022, U.S. greenhouse gas emissions totaled 6,341.2 million metric tons of carbon dioxide equivalents, and 5,487.0 million metric tons of carbon dioxide equivalents after accounting for sequestration from the land sector.
- Emissions increased in 2022 by 1 percent (after accounting for sequestration from the land sector) compared to the previous year. The increase in total greenhouse gas emissions was driven largely by an increase in CO2 emissions from fossil fuel combustion. In 2022, CO2 emissions from fossil fuel combustion increased by 1 percent relative to the previous year. This increase in fossil fuel consumption emissions was from increased energy use, due in part to the continued rebound in economic activity after the height of the COVID-19 pandemic.
- Greenhouse gas emissions in 2022 (after accounting for sequestration from the land sector) were 17 percent below 2005 levels.
Explore the Data
EPA has developed an interactive tool that provides access to data from the national greenhouse gas inventory. Visit the Greenhouse Gas Inventory Data Explorer to create customized graphs, examine trends over time, and download the data. Note: The Inventory Data Explorer and Data Highlights will be updated with data through 2022 with publication of the final Inventory in April after completion of public review of the draft report.
