The green concept and management have also been well-recognized strategies to promote a hotel’s competitive advantage. Based on a sample of 43,312 hotels from 328 destinations in 28 countries, we empirically examined antecedents of TripAdvisor’s GreenLeader participation. Our binary logit model indicates that hotels with better online reputations, larger size, lower level of urbanization economies, and higher reliance on business travelers are more likely to join the GreenLeader program. For GreenLeader hotels, online reputation factors and hotel size also explain their ranks. Lastly, implications are discussed.
