All 2000 data are preliminary.
MMTC = million metric tons of carbon
Tons of carbon can be converted to tons of carbon dioxide by multiplying by 3.667.
Carbon dioxide is a major greenhouse gas emitted from the burning of fossil fuels.
The transportation sector surpassed the industrial sectors carbon dioxide emissions for the first time in 1998. Historically, the industrial sector was the largest emitter of carbon dioxide.
|U.S. Carbon Dioxide Emissions||1999||2000*|

|Industrial emissions percent change from previous year||0.21||1.46|
|Residential emissions percent change from previous year||0.35||3.79|
|Commercial emissions percent change from previous year||0.00||4.92|
