In view of the serious environmental problems we are currently facing, taking action to protect our planet is becoming more persuasive and important. Along with various environmental initiatives, the concept of green marketing emerged in the late 1980s. Some hotels have taken various initiatives to position themselves as green hotels, including the use of eco-labels as a marketing ploy to attract customers. Nevertheless, some of the hotels that use these green marketing strategies have been accused of “green washing”. The main aim of this study is to investigate Hong Kong hotel manager perceptions of the relative importance of different green marketing strategies. Questionnaires containing 30 attributes were distributed to this effect. The findings reveal that hotel managers equally perceive “Hotel green marketing should begin with green product and service design”, “Hotels provide products and services that do no harm to human health” and “The Internet is an effective channel to market a hotel’s green initiatives to customers directly” as the top green marketing ploys. Independent t-tests and one-way ANOVA were also used to examine significant differences in the way hotel managers with different professional backgrounds and individual demographic characteristics rate the importance of hotel-related green marketing strategies. The findings indicate that lower-grade hotels tend to adopt lean green marketing strategies, whereas hotels with larger sizes or formal environmental management systems are likely to adopt shaded or extreme green marketing strategies. The study also provides a number of insights to help hotel managers and especially marketers better understand the implementation and importance of different green marketing strategies, thereby allowing them to employ suitable measures to avoid the “green washing” designation and attract more green-conscious travellers.
