(1) Teragrams of CO2 equivalent-1 TgCO2Eq = 1 million metric ton of carbon equivalent x (44/12). A teragram equals 1 trillion grams.
(2) Aircraft emissions are from all jet fuel (less bunker fuels) and aviation gas consumption.
(3) "Other" carbon dioxide emissions are from motorcycles, construction equipment, agricultural machinery, pipelines, and lubricants.
(4) Emissions from international bunker fuels include emissions from both civilian and military activities, but are not included in totals.
NOTE: Highway total includes passenger cars, buses, light-duty trucks, and other trucks.
