This study investigates potential barriers to the adoption of environmental technologies used in Hong Kong hotels. Data were collected via in-depth semistructured interviews with senior hotel professionals including general managers, financial controllers, directors of engineering department, and environmental management system managers. The research findings illustrate several specific barriers to adoption of environmental technologies which are grouped under three categories: (1) product-related barriers, (2) external barriers, and (3) internal barriers. The study findings are discussed and specific recommendations for overcoming these barriers are put forward. Conclusions and suggestions for future research are also provided.
