Zusammenfassung
In this paper, the utility of the Ecological Footprint method to assess the environmental impact of a
public transport system is discussed, and a new method to supplement the Ecological Footprint to
consider resource demand is shown. The method was used to determine the Ecological Footprint of
the biggest provider of public transport in Vienna, namely the Wiener Linien. The study assessed
the contribution of the individual modes of public transport -subway, tram and bus- as well as the
impact of management and service infrastructure by defining and analysing three distinct scenarios.
In this paper, we will show the contribution of the business categories –electricity and fuel;
buildings; mobile and immobile assets; consumables; vehicles; buildings- to the Ecological
Footprint of the Wiener Linien, and supplement that information with data on resource demand. In
our study, we compared three scenarios. The first scenario set the reference for “business as usual”,
the second scenario added one subway line while the third scenario significantly expanded tramservice.
While the Ecological Footprint, normalised for seat-km, stays about the same, a
considerable difference in resource demand, normalised for seat-km as well, was found. For this
study we followed a data-heavy bottom-up approach for data acquisition, which will be presented
in this paper as well.
