Purpose The objective of the work is to have an insight into the degree of the contemporary concept of greening the organization through human resource management (HRM) and to attempt to bridge the gap toward environmental awareness, as well as to observe the dimensions of green HRM (GHRM) practices and its impression toward environmental sustainability by using analytical hierarchy process (AHP) and FAHP. Design/methodology/approach The research was carried out in two phases; multi-method was employed. The first phase mainly includes a systematic review to convene comprehensive knowledge of widespread GHRM practices to leverage environmental sustainability. In the second phase, the AHP and fuzzy AHP (FAHP) were employed to examine the influence of the respective dimension of GHRM practices toward environmental sustainability. Findings This study emphasizes the status of GHRM practices such as green recruitment and green selection, green performance management, green training and development, green compensation and rewards, green welfare aspects as a way to aid environmental issues. The findings suggest that these initiatives help to leverage environmental sustainability. Further, this paper reveals that green compensation and rewards have the highest impact on leveraging environmental sustainability. However, this study also emphasizes the comparative study of GHRM dimensions through AHP and FAHP. Originality/value As existing studies reveal, there is least research carried on this field of study and no study was conducted using AHP and FAHP in this field. Thus, this study reveals the necessity to discover the degree of concern toward GHRM practices in context to India.
