Social and environmental impacts, responses and indicators are reviewed for the mainstream tourism sector worldwide, in five categories: population, peace, prosperity, pollution and protection. Of the ∼5000 relevant publications, very few attempt to evaluate the entire global tourism sector in terms which reflect global research in sustainable development. The industry is not yet close to sustainability. The main driver for improvement is regulation rather than market measures. Some tourism advocates still use political approaches to avoid environmental restrictions, and to gain access to public natural resources. Future research priorities include: the role of tourism in expansion of protected areas; improvement in environmental accounting techniques; and the effects of individual perceptions of responsibility in addressing climate change.
