Glossary:Activity factor
A numerical value describing the size of the population of emitting devices such as length of pipelines, number of valves (per type), number of pneumatic devices (per type), or the frequency of emitting events such as number of operating vents. (Note – This is not an exhaustive list, the Activity Factor is linked to the Emission Factor and expressed by a numerical value consistent with the Emission Factor.)[1]
The population of emitting equipment. For example, activity factor could refer to the mileage of natural gas pipeline, the count of thief hatches on a facility or the mechanical power of gas turbines.[2]
