In this study, we aim to investigate environmental management representatives’ perceptions regarding the extent of the contribution of green hotel practices to achieving the environment-related sustainable development goals (SDGs). To achieve this aim, a questionnaire was developed and directed to the person in charge of environmental duties in the investigated hotels, who were selected by a convenience sample method. A sample of 48 participants from four and five Green Star hotels, representing 63% of the total Certified Green Star hotels in Egypt, was surveyed. The findings of the study revealed that the implementation of green hotel practices in the certified four and five Green Star hotels surveyed contributed positively to achieving SDG 6, SDG 12, SDG 7 and SDG 13, respectively. The main driver of the adoption of Green Star criteria was the hotels’ commitment to environmental sustainability. The findings also indicated that, overall, there were statistically significant differences between four and five Green Star hotels in all SDGs addressed. The main implication of this study is that hotel operators should properly incorporate green hotel practices into their operational plans to achieve the environment-related SDGs.
