Inventory of U.S. Greenhouse Gas Emissions and Sinks (1990-2006) from the U.S. EPA

The data covers anthropogenic emission trends from 1990-2006 and ensures that the U.S. emissions inventory is comparable to the United Nations' Framework Convention on Climate Change (FCCC) signatory countries according to methodologies similar to those recommended in the Revised 1996 IPCC (Intergovernmental Panel on Climate Change) Guidelines for National Greenhouse Gas Inventories (IPCC/UNEP/OECD/IEA 1997).

The greenhouse gases in the inventory include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Also included are the halocarbons chloroflurocarbons (CFCs) and hydrochloroflurocarbons (HCFCs) and hydroflurocarbons (HFCs), perflurocarbons (PFCs), and sulfur hexafluride (SF6). Emissions of gases that do not directly affect global warming, but are instrumental in the destruction of ozone include: carbon monoxide (CO), oxides of nitrogen (NOx), and nonmethane volatile organic compounds (NMVOCs) as well as aerosols produced by the emissions of sulfur dioxide (SO2).
