The successful implementation of environmental programs begins with environmental knowledge, understanding, and information released from top management to lower-level employees. It is therefore important for managers to learn more about any relationships that may exist between environmental knowledge and employee ecological actions. Understanding which environmental determinants affect hotel employees’ behavior in implementing green practices is critical to the successful implementation of hotel environmental programs. We suggest that hotel organizations should make more effort to train their managers and encourage them to improve their communication skills and interpersonal relationships with their employees. Regular communication via departmental daily briefings and annual staff meetings for exchange of latest environmental information and environmental performance of the company can be arranged. Managers should be better able to detect the direct and indirect influences of employees’ environmental knowledge in the attitudinal processes that relate to employees’ ecological behavior. Because the hotel industry is labor intensive, greater employee awareness and concern about organizations’ environmental programs can not only improve employees’ involvement but also promote organizations’ environmental friendly images and reputations, which lead to customer satisfaction and loyalty.
