Inventory of U.S. Greenhouse Gas Emissions and Sinks
Public Review of Draft U.S. Inventory of Greenhouse Gas Emissions and Sinks: 1990-2018
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. Each year since the early 1990s, EPA has published the draft report in February, to allow for public comment prior to publishing the final report by April 15.
Per an announcement in the Federal Register (FR) FRL-10004-79-OAR, the draft 1990-2018 Greenhouse Gas Emissions Inventory 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 13, 2020. Learn more about the draft report and how to submit comments.
About the Emissions Inventory
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. The gases covered by the Inventory include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. The Inventory also calculates carbon dioxide removal from the atmosphere by “sinks,” e.g., through the uptake of carbon and storage in forests, vegetation, and soils.
The national greenhouse gas inventory is submitted to the United Nations in accordance with the Framework Convention on Climate ChangeExit. In preparing the annual emissions 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.
See 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 Data Explorer will be updated with publication of the Inventory in April after completion of public review.
