USDA’s Office of the Chief Economist’s Climate Change Program Office has released the “U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008” report. This report provides detailed estimates of greenhouse gas emissions and carbon sequestration from the management of livestock, croplands, and forests, as well as from energy use in agriculture that will be useful to states and localities. In 2008, agricultural greenhouse gas sources accounted for about 6% of total U.S. greenhouse gas emissions.
It was prepared collaboratively with contributions from the USDA Agricultural Research Service, USDA Forest Service, USDA Natural Resources Conservation 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.
