EPA Publishes 29th Annual U.S. Greenhouse Gas Inventory
Inventory of US Greenhouse Gas Emissions and Sinks (GHG Inventory)
This inventory presents a national-level overview of annual greenhouse gas emissions from 1990 to 2020. The GHG Inventory covers seven key greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. In addition to tracking U.S. greenhouse gas emissions, the Inventory also calculates carbon dioxide that is removed from the atmosphere through the uptake of carbon in forests and other vegetation.
