The environment is emerging as an important global issue, raising interest and inspiring a sense of responsibility to establish and adopt environmentally-friendly policies and practices in hotel restaurants that can have a serious impact on the environment. In this context, this study identified the factors that influence acceptance intention of green practices among hotel kitchen employees and proposed an effective way forward for companies to efficiently expand such activities and furthermore, develop into a sustainable enterprise. In an effort to attain the goals of this study, a contemplation of preceding research was undertaken to identify factors influencing an individual’s environmental behavior, namely, environmental knowledge, environmental concern, and perceived effectiveness regarding environmental behavior. These factors were applied to the Theory of Planned Behavior by Aizen (1991). The concept of moral norm was also administered to empirically verify the relation between variables. A parent population was selected among kitchen employees in five-star and four-star hotels located in Seoul. As a result of the verification, six hypotheses out of a total of thirteen were found to be meaningful, whereas seven hypotheses were not. Finally practical implications and suggestions for furture research are discussed.
