The impact of digitialisation on sustainable tourism development in its environmental and social dimensions will be investigated. In a first step, current developments in the digitisation are systematically identified and their current and future contribution to sustainable tourism devel-opment is examined. In doing so, both the digitialisation on the part of the customers (tourists) and the providers is taken into account, with an emphasis on Big Data-Analyses. The focus is on the use of digital applications during the trip, while the attention will not be on travel prepara-tion or follow-up.
In a second step, the opportunities and risks arising from the analysis are identified and evaluat-ed. Special consideration is given to the behaviour of different user groups with influences on resource use, environment and climate. The aim is to analyse possible environmental damage as well as opportunities for climate, resource and environmental protection and social sustainabil-ity aspects (e. g. avoidance of overtourism).
