Modelling the ecological footprint of green travel plans using GIS and network analysis: from metaphor to management tool?

The author explores the use of ecological-footprint analysis for evaluating and communicating the environmental implications of transport alternatives within a company travel plan. From a case study of the Vodafone headquarters in Newbury, a component ecological footprint methodology is developed that employs geographic information systems (GIS) and network analysis to model the impacts of commuting activity prior to and after implementation of the company's 'green travel plan'. Having provided an in-depth exploration of the footprint approach, the author considers the extent to which ecological footprinting may be used as a management tool for formulating, implementing, and refining company travel plans, in addition to its well-established role as a metaphor for communicating the consequences of consumption.
