Greenhouse Gas Emissions

Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2015

View the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2015 (published 2017), developed by the U.S. Government to meet U.S. commitments under the United Nations Framework Convention on Climate Change (UNFCCC). Visit the public comments page to learn more about comments EPA received on the public review draft of the 1990-2015 GHG Inventory report. Prior year versions of the GHG Inventory are available on the U.S. Greenhouse Gas Inventory Archive page.
