Abstract
When thinking about aviation and climate, researchers tend to focus on airborne operations. This aspect is obviously important, but the landside accessibility of an airport also results in climate impacting emissions. This paper analyses the current emissions balance originating from the passenger and employee transport to and from Brussels Airport. The CO2 emissions related to the different landside access modes are inventoried and in a second step suggestions are made towards potential improvements of the situation. The measures suggested in this paper consist of a transition towards hybrid and battery electric vehicles, a modal shift away from internal combustion engine vehicles and some specific political interventions. When combined, it is calculated that the suggested measures can save more than 30 % percent of the CO2 emissions originating from the landside mobility of Brussels airport.
