... have had success in reducing emissions from GSE, and the action required to reduce GSE emissions is fairly straightforward -- upgrade the GSE fleet (e.g., to run on compressed natural gas [CNG] or electricity, see Section 5.2.2)

... This is at least in part due to ORD's inclusion of GAV emissions outside of the airport proper as was needed based on the purpose of the emissions inventory. HAP emissions are not necessarily proportional to total VOC emissions, however.

... 3.1.3 Stationary Sources Stationary sources such as evaporative emissions from fuel storage, HVAC systems, and generators account for 25% to 30% of reported VOC emissions at BOS and PHL, but are only reported at a minor 2% at ORD. This is one of many potential discrepancies among the self-reported airport emissions that could be elucidated if accurate fuel use inventories were available (Section 3.1.5)

... . For the GSE emissions of HAPs per LTO to be comparable to the aircraft contribution, the GSE would either have to consume a comparable amount of fuel -- if the HAP emission indices (in grams of pollutant per kg of fuel)
