National Greenhouse Gas Inventory
Periodically, USDA produces an updated inventory of GHG emissions and carbon storage for the agriculture and forestry sectors. These reports are consistent with the annual emissions reporting done by EPA, but provide an enhanced view of the data regionally and by land use.
U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2013
In 2013, agricultural greenhouse gas sources accounted for about 9% of total U.S. greenhouse gas emissions. The U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2013 was developed to provide a comprehensive assessment of the contribution of U.S. agriculture and forestry to greenhouse gas emissions and carbon sequestration. It provides an in-depth look at greenhouse gas emissions and carbon sequestration at the state and regional scales.
The report was prepared with contributions from the USDA Agricultural Research Service, USDA Forest Service, USDA Office of Energy Policy and New Uses, USDA Climate Change Program Office, U.S. Environmental Protection Agency (EPA), and researchers at Colorado State University. The estimates in the USDA GHG Inventory are consistent with those published by the EPA in the official Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2013.
