Abstract
There is evidence in the literature that green HRM practices improve environmental profitability. On the other hand, existing research has failed to explain how GHRM can support the development of a green culture and green innovation influence the firm's environmental performance and long-term growth. This study investigates the relationship between GHRM, green culture, green innovation, and a firm's environmental performance. In addition, the study examines the mediating role of green culture and green innovation in the relationship between GHRM and environmental performance. This research conducts a large-scale study of 290 employees from Manufacturing firms in Malaysia. The research results provide managers with a better knowledge of how GHRM helps develop sustainable culture and green innovation and how these elements contribute to the improvement of environmental performance inside the organization. This study also makes a significant contribution in terms of novelty and research relevance by demonstrating that green culture and green innovation positively mediate the relationship between GHRM and environmental performance in a sustainable manner. Managers will understand the GHRM required to develop an ecologically conscious culture and promote green innovation among environmentally conscious employees. Finally, we highlighted the importance of this study for top management in the sense of mediating the role of green culture and green innovation and the consequences for future generations of responsible managers who will acquire this knowledge.
