The report is an initial evaluation of significant anthropogenic sources of radiatively important trace gases. Emissions of greenhouse gases from human activities--including fossil fuel combustion, industrial/agricultural activities, and transportation--contribute to the increasing concentrations of radiatively important trace gases (RITGs) in Earth's atmosphere. Trace gases of concern include CO2, N2O, CH4, chlorofluorocarbons, and O3. NOx and nonmethane hydrocarbons, while not themselves radiatively active, can contribute to the buildup of RITGs. The U.S. EPA has conducted several research projects characterizing emissions from specific sources of RITGs, the purpose of which was to rank sources of RITGs according to their potential impacts on radiative forcing and to develop country- and source-specific emission factors where data were adequate to warrant emission factor development. Country-specific emission factors were developed for coal-fired utility boilers, natural gas transmission/distribution systems, municipal solid waste landfills, rice cultivation, and transportation sources. Sources for which country-specific emissions data were collected, but for which emission factor development could not be supported at this time, include coal mining operations and miscellaneous/industrial sources of methane.
