`Sustainable mobility' has been adopted as an overall objective for European transport policy, and similar intentions are expressed in other parts of the world. However, little has been done to define what `sustainable mobility' would actually imply for our understanding and assessment of transport. We suspect that this much used term could merely end up acting as a lubricant to the very development it was meant to challenge: The ever increasing movement of people and goods. In this article we attempt to place transport in the context of sustainable development principles. We emphasis the need to include principles of development (increasing well-being and equity) as well as sustainability (preserving natural and man-made capital). Four such principles are suggested, taking inspiration from Herman Daly and others. We then turn to explore the main features of transport, establishing a comprehensive transport concept. The concept combines a systems perspective with a service perspective. Omitting either one would disable a complete consideration of sustainable development. Our confrontation of the four principles with the reality of current transport trends gives rise to several critical implications. The most important of which relate to the contribution of transport to depleting natural capital and quality of life. Moreover, we are also forced to challenge the value of increasing mobility itself, if other forms of access may provide relevant substitutes. The article thereby outlines some conceptual foundations for a transport policy that could qualify as sustainable. (A)
