Fugitive emissions are defined as emissions that are not physically regulated but arise from deliberate or inadvertent discharges into the atmosphere. Accidental releases may be produced by equipment leaks, faulty seals or joints, or intentional venting, flaring, or discharge of GHGs. According to the EPA “A stack, chimney, vent, or other functionally comparable opening could not reasonably contain fugitive emissions”. This document will concentrate on various fugitive emissions sources that are prevalent in various industries and are used by organizations: air conditioning and refrigeration systems, fire suppression systems, and the acquisition and discharge of industrial gasses.
The complicated element of the process is fugitive emission calculations since the activity data used to estimate GHG emissions is complex. Various approaches exist for calculating fugutive emission based on activity data type and data acquisition.
