KEY: CO2 = carbon dioxide; R = revised.
1Electricity-related emissions are not included in the transportation sector and U.S. totals for CO2 emissions from fossil fuel combustion.
NOTES: CO2 equivalent is computed by multiplying the weight of the gas being measured by its estimated Global Warming Potential (GWP). The Intergovernmental Panel on Climate Change developed the GWP concept to compare the ability of one GHG to trap heat in the atmosphere to another gas. Carbon comprises 12/44 of CO2 by weight. Numbers may not add to totals due to rounding. Electricity-related emissions are not included in this table.
