emissions inventory

Show Summary Details

Quick Reference

A list of the amounts of air pollutants that are emitted by each particular source within a given area, which is used to establish emission standards. The need for such inventories became obvious at the 1992Rio Earth Summit and during debate leading to the 1997Kyoto Protocol. An emissions inventory would usually include information on the chemical or physical identity of the pollutants included, the geographical area covered, the institutional entities covered, the time period over which the emissions are estimated, and the types of activities that cause emissions. Emission inventories are used in various ways. For example, they provide valuable inputs to air quality models, allow the success of air quality policies and standards to be evaluated, and enable regulatory agencies to establish compliance records with allowable emission rates.
