U.S. CARBON DIOXIDE EMISSIONS

U.S. Carbon Dioxide Emissions from Energy Use by Sector (annual data)

U.S. Carbon Dioxide Emissions from Energy Use by Sector (annual data)

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.
