a list of air pollutants emitted into a community's, a state's, a nation's, or Earth's atmosphere in amounts per some unit time (e.g., day or year) by type of source. An emission inventory has both political and scientific applications.
A catalog or list of each emission source within a region, along with the location and emission height, type of air pollutants emitted, rate of emissions, initial emission characteristics such as buoyancy and initial momentum, and emission schedule if not continuous. Such a catalog often includes anthropogenic sources such as individual point sources from industry including some farming activities, line sources along roads, and area sources associated with quasi-uniform distributions of sources such as houses in a residential neighborhood. Biogenic area sources are also included, such as lawns, parks, farmland, pasture, and forests.
A list of primary air pollutants emitted into a given communityâ€(tm)s atmosphere, in amounts (commonly tons) per day by type of source. The emission inventory is basic to the establishment of emission standards. Also see Emission Factor.
