The European Union’s targets call for 10 per cent of all transport fuel derived from renewable sources by 2020. Sweden sets a more challenging goal to have a totally fossil-free vehicle fleet by 2030 [1]. Swedavia’s own vision is to achieve zero fossil-based CO2 emissions by 2020 [2]. The main function of the airport facilities is providing access to aircrafts for both passengers and cargo. An airport operator’s vehicle fleet is commonly the second largest energy user next to building/facilities. A major part, up to 95%, of an airport operator’s CO2 emissions can be caused by the operational vehicle fleet. To specify the CO2 emission reduction strategy of an airport’s vehicle fleet a specific energy analysis shows necessary. Moreover, a clear roadmap of improvements and upgrades of the vehicle fleet configuration is needed to secure a goal of zero fossil-based CO2 emissions. With regard to the vehicle fleet electrification aspect, many airports are ahead of Swedish airports. Since June 2015, 35 electric buses at Amsterdam Airport Schiphol have been transporting passengers to and from aircraft to gate [3]. London Heathrow Airport has one of the largest fleets of electric, airside vehicles in Europe; 850 of 8000 vehicles are electric motor powered [4]. The first electric bus fleet started operating on-airport by late 2016 in Sydney Airport, Australia [5]. However, no airports have yet even got close to zero CO2 emission vehicle fleet. This pre-study investigates, on the example of Swedavia’s vehicle fleet, a typical airport operator vehicle fleet configuration and its CO2 emission levels. Based on this use case study, an emission reduction strategy and a roadmap for realization of a zero fossil CO2 emission goal is proposed. This strategy also addresses energy efficiency targets after 2020.
