Emissions of Greenhouse Gases in the U. S.
Release Date: March 31, 2011 | Next Release Date: Report Discontinued | Report Number: DOE/EIA-0573(2009)
Greenhouse Gas Emissions Overview
[a] CO2 emissions related to petroleum consumption (includes 64 MMTCO2 of non-fuel-related emissions).
[b] CO2 emissions related to coal consumption (includes 0.3 MMTCO2 of non-fuel-related emissions).
[c] CO2 emissions related to natural gas consumption (includes 13 MMTCO2 of non-fuel-related emissions).
[d] Excludes carbon sequestered in nonfuel fossil products.
[e] CO2 emissions from the plastics portion of municipal solid waste (11 MMTCO2) combusted for electricity generation and very small amounts (0.4 MMTCO2) of geothermal-related emissions.
[f] Includes mainly direct process emissions. Some combustion emissions are included from waste combustion outside the electric power sector and flaring of non-marketed natural gas.
[g] Includes methane emissions related to energy, agriculture, waste management, and industrial processes.
[h] Includes nitrous oxide emissions related to agriculture, energy, industrial processes, and waste management.
[i] Includes hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
[j] Includes only energy-related CO2 emissions from fossil fuels. Emissions are allocated to end-use sectors in proportion to U.S. ratios. Therefore, the sector CO2 values shown here do not match the values in the carbon dioxide chapter.
[k] Includes vessel bunkers and jet fuel consumed for international travel. Under the UNFCCC, these emissions are not included in country emission inventories. Emissions are subtracted from the transportation sector total.
[l] CO2 emissions from electricity generation in the commercial and industrial sectors are included in those sectors.
[m] Non-CO2: Direct stationary combustion emissions of methane and nitrous oxide plus indirect power sector emissions of methane, nitrous oxide, and other greenhouse gases.
[n] Non-CO2: Direct stationary combustion emissions of methane and nitrous oxide plus indirect power sector emissions of methane, nitrous oxide, and other greenhouse gases. Additional direct emissions include emissions from landfills, wastewater treatment, and commercial refrigerants.
[o] Non-CO2: Direct stationary combustion emissions of methane and nitrous oxide plus indirect power sector emissions of methane, nitrous oxide, and other greenhouse gases. In addition, all agricultural emissions are included in the industrial sector as well as direct process emissions of methane, nitrous oxide, and the other gases.
[p] Non-CO2: Direct mobile combustion emissions of methane and nitrous oxide. Also, emissions related to transportation refrigerants are included.
Source: Estimates presented in this report. CO2 emissions by end-use sector are based on EIA's estimates of energy consumption by sector and on industrial process emissions. CO2 emissions from the electric power sector are allocated to the end-use sectors based on electricity sales to the sector. Non-CO2 emissions by end-use sector are allocated by direct emissions in those sectors plus indirect emissions from the electric power sector allocated by electricity sales. Data are preliminary. Totals may not equal sum of components due to independent rounding.
