ABSTRACT‘Going green’ has become an inevitable trend for the hotel industry given companies’ need for cost savings, customers’ increasing environmental awareness, and governmental policies and regulations. This study aims to investigate potential green hotel customers’ decision-making process and the factors influencing that process. The study produced the following results: (1) customers’ environmental concern (EC) (i.e. environmental knowledge, consciousness of environmental issues, and daily ecological behavior) had a significant impact on their attitude toward green practices (AGP), overall attitude toward green hotels (OA), and behavioral intention (BI). Further analyses indicated that environmental knowledge had positive influences on both AGP and OA, while daily ecological behavior was the most powerful predictor of BI; (2) AGP may be measured multi-dimensionally. In addition, the results revealed a three-factor solution of AGP, including practices improving green service quality, practices preventing pollution, and practices reducing energy. The relationships between AGP and OA, as well as OA and BI were moderated by ‘green hotel experience’. For the group without green hotel experience, AGP significantly influenced OA, and practices improving green service quality was the most powerful predictor of BI.
