Hotels across the globe are increasingly encouraging guests to embrace green practices. Yet while guests think they are supporting the environment by shutting off lights and reusing towels, they may in fact be victims of "greenwashing," a corporation's deceitful practice of promoting environmentally friendly programmes while banking the extra profits.Greenwashing practices, such as a sign that reads "save the planet: re-use towels," coupled with claims of corporate social responsibility, have soiled the trust of American consumers who are increasingly recognizing hotels' green claims may be self-serving. This could cause hotels to lose valuable repeat customers.
