Introducing environmental equity dimensions into the sustainable transport discourse: Issues and pitfalls

Environmental equity considerations should be an essential ingredient of any sustainable transport strategy. Yet, it is unclear how environmental equity considerations can be incorporated into the sustainable transport discourse in a meaningful manner. The paper explores the multiple facets of the meaning of environmental equity in the case of transport. Then, the issues that need to be addressed in any analysis of each facet are delineated. On this basis it is suggested that the conventional environmental equity analysis, whereby the affected areas are compared to unaffected areas, is unlikely to render robust or meaningful results. Rather, the focus of research should be on the equity implications of policies geared to mitigate transport systems' environmental externalities, and on comparisons of users of the different transportation systems to those exposed to the negative environmental externalities of these systems. The results of such studies could provide direct inputs into comprehensive balanced policy packages within a sustainable transport strategy.
