Key research themes on urban space, scale, and sustainable urban mobility

Land-use policies are frequently proposed as a means of reducing the negative impacts of transport on the environment, such as emissions of CO2 and pollutants, and noise nuisance. In this article we discuss whether land-use policies make sense as a strategy for reducing vehicle travel and lessening environmental impacts. We conclude that they do, but that the greatest benefits may come from the enhancement of accessibility. We argue that land-use policies should be evaluated across a much broader range of benefits than is generally done at present.
