The tourism industry’s contribution to climate change is significant, especially due to air travel. The purpose of this paper is to explore psychological determinants of more sustainable tourism mobility decision-making. We present the findings from an exploratory study of young travellers, from Australia and Sweden into the links between attitude to anthropogenic climate change (AAcc) and demand for information about the environmental impacts of personal travel; and tourism suppliers’ sustainability orientations. We find AAcc related to a number of key sustainable tourism mobility information demand variables, for example, desire for more information about sustainability on travel companies’ websites, as presented in Table 1. Implications and further research directions are discussed.
