Concern over emissions has led airports to develop emissions reduction goals and engage in clean energy innovation initiatives. To date, the majority of low- and zero-emissions projects and goals have focused on ground support equipment. Many opportunities remain for reducing emissions from airport ground transportation vehicles. The FAA has multiple successful programs such as the Airport Zero Emission Vehicle (ZEV) in infrastructure incentives programs and the Voluntary Airport Low Emission (VALE) program. However, airports would benefit from a process that would help them more easily understand emission reductions and lifecycle costs, and a tool to help identify the best zero-emissions or low-emissions strategy for their airport.
The objectives of this research are to (1) examine how airport operations can drive and facilitate the technological developments in the field through incentives, policies, and infrastructure changes and (2) produce a guidebook and accompanying tool that complements existing programs, such as VALE, to help airports develop an overall strategy that supports the reduction, and eventual elimination, of emissions from airport ground transportation. The guidance should consider the many external components related to airport transportation emissions, such as the associated emissions from the generation of electricity used to power ZEV.
