This research applies the binding communication model to the sustainable communication strategies implemented in most hotels. The binding communication model links a persuasive messag e with the implementation of a low-cost commitment to strengthen the link between the attitudes and behavior o f those receiving the message. We compared the effectiveness of a classical communication strategy ( n = 86) with that of a binding communication strategy ( n = 101) to encourage guests to choose sustainable behavior. Our results show that using the binding communication strategy generates significantly more sustainable behavior in guests than using the classical communication strategy. We discuss our results and suggest future avenues of research
