Emission Factor - an overview | ScienceDirect Topics

Method of control – indicates whether the emission factor was measured from a source that was uncontrolled or had a pollution control. • Value – emission factor value in scientific notation. For example, a value of 1.2E+01 is the same as 12.0. • Emission factor: • Unit – the unit that the emission factor is reported in. •
