Greenhouse Gas Emissions

U.S. Greenhouse Gas Inventory Report Archive

This page contains past versions of the U.S. Greenhouse Gas Inventories developed by the U.S. government to meet U.S. commitments under the United Nations Framework Convention on Climate Change (UNFCCC). Article 4.1a of the UNFCCC requires that all countries periodically publish and make available to the Conference of the Parties (COP) inventories of anthropogenic emissions and removals by sinks of all greenhouse gases not controlled by the Montreal Protocol. Learn more about greenhouse gas emissions.

Subsequent decisions by the COP require the United States to submit these reports on an annual basis and include emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) and removal of these gases by sinks. Below is a complete list of past inventory submissions:
