Following the footsteps of resource-based view theory, the present study attempted to examine green HRM and its impact on green innovation followed by the interplay of green transformational leadership. The study collected triadic data by using survey questionnaire from 185 pharmaceutical firms in Australia. Through using structural equation modeling technique, bootstrap procedures were applied to assess the hypothesized relationships. Results from the data analysis suggest that green HRM prospects of green ability and motivation have significant relationship with green innovation. Accordingly, the results also indicated significant relationship between green transformational leadership and green innovation. Notably, the study advanced literature in the area by confirming the moderating potential of green transformational leadership on green ability-green innovation and green motivation-green motivation relationship. Overall, the present research has advanced understanding of green GRM and green leadership to utilize personnel prospects to further green innovation effectively.
