In Search of Sustainability

The term "sustainability" is increasingly used in transportation, but ambiguity about what it really means or what it encompasses remains. This paper highlights a scan of the literature and web products to assess the characteristics of sustainable practices, especially in relation to the transportation sector. Findings indicate that there is a need to define the subject field more rigorously and to get a better sense for the scale and scope of sustainable activity. The most frequently employed base for sustainability is the triple bottom line, where economic growth, eco-efficiency and socioeconomic factors intersect. At the present, much sustainability practice is strong on environmental factors, but weak on areas such as economic and social factors. Directions for future research are suggested.
