NOTE: A teragram = 1 trillion grams. Other carbon dioxide emissions are from motorcycles, construction equipment, agricultural machinery, pipelines, and lubricants. International bunker fuel emissions (not included in the total) result from the combustion of fuels purchased in the United States but used for international aviation and maritime transportation. Thus, aircraft and ships and boats data included in U.S. total emissions involve only domestic activities of these modes as do all other data shown. Alternative fuel vehicle emissions are allocated to the specific vehicle types in which they were classified (i.e., passenger cars, light-duty trucks, and other trucks and buses).
