Purpose – To provide a behavioural perspective on the relationship between transport and climate change.

Methodology/approach – The factors influencing travel behaviour and the elements critical to behaviour formation are reviewed. The importance of behaviour change measures to reduce the impact of transport on climate change, and the application of behaviour change measures to increase the sustainability of transport, are examined.

Findings – There have been a range of travel behaviour measures implemented, such as individualised marketing programmes and travel plans, which have demonstrated some behavioural change impacts, in turn affecting climate change emissions, although they tend to be localised and small-scale.

Social implications – There is a real challenge to encourage individuals within society to exhibit more sustainable travel behaviour.

Originality/value – A range of behavioural issues still need to be resolved in terms of the relationship between transport and climate change, including a need to influence attitudes, to bridge the gaps between attitudes and both behaviour and intention, to make an impact at points of transition for individuals, to use cognitive dissonance as a way of harnessing social norms, and to understand more fully social pressure and group influence.
