Abstract
This paper presents the results of a two round Delphi survey conducted into expert opinion on the development of indicators to measure the movement of the tourism product at a company/resort level towards a position of greater or lesser sustainability. This research forms part of a wider project to develop indicators that consumers can use in the selection of their holidays and promote a more sustainable form of tourism. The results of this expert survey show considerable disagreement over “sustainability” and where the borders of the concept exist. In addition, the research identified contrasting views over the use of qualitative versus quantitative indicators and the role that consumer pressure can play. The use of the Delphi technique to address complex and uncertain issues is also explored.
