ABSTRACT
In his chapter, Peter Hall reveals that he is uniquely equipped to reflect on the relationships between transport, land-use change and environmental impact across western Europe. However, the overall result of his detailed and knowledgeable reflection is ultimately depressing, for he shows just how ignorant we remain about the way that some of these relationships work, and hence how weak is the basis for any policy intervention. This is particularly bad news at this time, because issues of environmental protection-often under the label of ‘sustainable development’—transport investment, and the promotion of economic development, are high on political agendas across much of Europe. Just when we need certainty, Hall reminds us of our ignorance.
