(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.
