Hotel guests care more about any green badge than who issued it.

Hotels often avoid eco-friendly changes because guests cannot easily see these efforts, leaving managers without clear rewards. Researchers tested whether displaying sustainability badges backed by a university could fix this issue. In a simulation, prospective guests saw hotel booking pages with one of four badge designs or no badge at all. Any badge made the hotel look more sustainable. It also made guests feel like part of a community of eco-conscious travellers, without causing negative emotions. However, university badges worked no better than generic environmental badges on almost all measures. The mere presence of a badge caused the effect. Researchers also interviewed ten hotel managers. Managers showed conditional interest in university badges because of shared values and community ties, not because the badge proved credibility. These shared identities may be the best way to encourage future eco-friendly hotel partnerships.

Why it matters

Hotels have many ways to reduce waste and energy use, but few adopt them even when they work. This paper suggests that visible recognition—like a sustainability badge—could shift that, but the badge's source matters less than simply having one. For guests, it signals belonging to a green community; for managers, it works best when they share values with the issuer, not just when it adds credibility.
