This research examines the effect of Green HRM practices on environmental performance with Green Employee Behavior, Green Organizational Culture, and Environmental Efficiency as the variables of interest. The main purpose is to establish the relationship between Green HRM practices and these factors, and improve environmental performance. The target population was 100 employees of HRM, and the data was collected and analyzed through CFA by employing random sampling techniques, and through the help of SPSS and AMOS. Therefore, based on the CFA results, Green HRM practices can be seen to have an impact on the behaviour of the employees and culture of the organization, but there is still room for improvement with some of the indicators.
