The inventory contains estimates of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2 O), Hydrofluorocarbons (HFC), perflourocarbons (PFC), and sulfur hexaflouride (SF6) emissions. The inventory also includes estimates of carbon sequestration in U.S. forests and, new this year, an updated assessment of emissions from the electric power industry. The technical approach used in this report to estimate emissions and sinks for greenhouse gases is consistent with the methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC) and reported in a format consistent with the United Nations Framework Convention on Climate Change (UNFCCC) reporting guidelines. The Inventory of U.S. Greenhouse Gas Emissions and Sinks is the latest in a series of annual U.S. submissions to the Secretariat of the UNFCCC.
