The research report provides an overview of digitisation trends and developments in tourism with regard to resource consumption and environmental impacts. As a result, eleven relevant categories of digitisation are identified and systematised. The categories can allocated within three spheres. These are: a) data connectivity, i.e. the collection, linking and processing of data; b) the data infrastructure enables data connectivity and the output of processed data in the form of digital service applications; and c) the data ecosystem is the business basis for such applications. Digitisation as such is not evaluated a priori either positively or negatively as a result of the assessment. Overall, significantly more positive (34) than negative (15) impact paths were identified.
