Research Highlights
 Despite the awareness on global climate change and reminder on environmental protection, it remains a challenge to promote sustainable tourism. The existing literatures on tourists’ sustainable behaviours pinpointed the emergence of environmentally-conscious tourists, yet the antecedents of their behaviours have not been fully established. Responsible environmental behavioral intentions are expected to be relevant predecessors for sustainable tourism. Thus, this study applies Responsible Environmental Behaviour model (REB) by Hines et.al (1986), which is tested alongside with Consumption Values Theory (Sheth et al., 1991) and destination image. This research proposed four hypotheses along with environmental consumption values and environmental attitude. In comparison, tourists that have higher levels of environmental knowledge and positive image of the destination will have higher intention to behave in an environmentally responsible manner.
