Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2012
The Inventory of U.S. Greenhouse Gas Emissions and Sinks tracks the national trend in greenhouse gas emissions and removals back to 1990. The report contains total U.S. emissions by source, economic sector, and greenhouse gas. EPA uses national energy data, data on national agricultural activities, and other national statistics to provide a comprehensive accounting of total GHG emissions for all man-made sources in the United States.
Totals reflect net emissions (the sum of all sources minus the sum of all sinks). Emissions from the Memo Items source category, which covers fuel combustion from international transport activities, are not included in inventory totals.
Emission metrics by fuel type and for specific chemicals within the HFC and PFC pollutant families are not included in the portal, but may be added in the future.
