This article reports the findings of how green human resource management (GHRM) practices can influence the perceptions of hotel employees regarding their organizations’ commitments to green psychological climate (GPC) and their environmentally responsible behavior. GHRM practices refer to the policies and procedures that support environmental sustainability and reduce the negative effects of business activities on the environment. The data used in the research were collected from 425 employees working in 11 5-star hotels in the Antalya/Manavgat districts. For data analysis, data scan analysis was used and the results were then analyzed through the AMOS software to test the structural model. The study has suggested that GHRM practices can positively affect the perceptions of employees concerning their commitment to GPC, which in turn can lead to more environmentally green behaviors. The study also examines the roles of environmental sensitivity and altruism in the relationship between GHRM practices and environmental behavior. The research has shown that individuals with higher levels of environmental sensitivity and altruism are more likely to exhibit environmentally responsible behavior. This means that the employees who are sensitive to environmental issues and have an altruistic personality are more liable to respond positively to GHRM practices of their businesses and are more likely to be environmentally responsible. The research has also emphasized that businesses should consider individual differences in environmental attitudes and behaviors when implementing GHRM practices.
