emission factor definition

emission factor means the average emission rate of a greenhouse gas relative to the activity data of a source stream assuming complete oxidation for combustion and complete conversion for all other chemical reactions;
emission factor means an estimate of the rate at which a regulated pollutant is released into the atmosphere, as the result of some activity, divided by the rate of that activity (e.g., production or process rate).
emission factor means a coefficient that quantifies the emissions or removals of a gas per unit activity, which is often based on a sample of measurement data, averaged to develop a representative rate of emission for a given activity level under a given set of operating conditions;

More Definitions of emission factor

emission factor means diesel PM or oxides of nitrogen (NOx) emission rate in grams per mile (g/mile) as shown in Appendix A. For engines that have been retrofitted with VDECS, the PM Emission Factor is reduced by 50 percent for a level 2 VDECS, and 85 percent for a level 3 VDECS; the NOx Emission Factor is reduced by the percentage NOx emission reductions that are verified, if any. The PM Emission Factor is not reduced for a level 1 VDECS.
emission factor means NOx emission rate in grams per brake-horsepower hour (g/bhp-hr) as shown in Appendix A. Engines certified to Family Emission Limits and flexibility engines must still use the emission factors in Appendix A.
emission factor means a unique value for determining an amount of a greenhouse gas emitted for a given quantity of activity (e.g., metric tonnes of carbon dioxide emitted per barrel of fossil fuel burned).
emission factor means a unique value for determining an amount of a greenhouse gas emitted for a given quantity of activity (e.g., metric tons of carbon dioxide emitted per gallon of gasoline burned).
emission factor means a unique value for determining an amount of a GHG emitted for a given quantity of activity (e.g., metric tons of carbon dioxide emitted per barrel of fossil fuel burned).
emission factor means diesel PM or oxides of nitrogen (NOx) emission rate in grams per brake-horsepower hour (g/bhp-hr) as shown in Attachment A, unless the engine is a Post-2007 Flexibility Engine (see definition).
emission factor for electricity means the default value, expressed in CO2e, representing the emission intensity of electricity consumed in production of goods.
