Abstract
This study investigated sustainability communication through destination websites. In particular, it suggested an online sustainability communication checklist (OSC-Checklist) that informs, motivates, and engages stakeholders to contribute towards the development of environmental, sociocultural, and economic sustainability. The OSC-Checklist was applied to the official websites of the top 50 competitive destinations with the aim of evaluating the extent to which each destination communicates sustainability on its website. The results indicated that the sample destinations lack an appropriate online approach to communicate sustainability. The results also revealed that the less developed and competitive destinations scored higher in terms of communicating sustainability than other more competitive developed destinations. Theoretical and practical implications are also provided.
