ABSTRACT Organizations increasingly adopt sustainability‐driven human resource management (HRM) practices to enhance both environmental performance and organizational agility. This study investigates how Green HRM mediates the impact of green innovation and green technology adoption on organizational agility and culture. This study uses data from 153 HR managers across various industries in India and applies partial least squares structural equation modeling (PLS‐SEM) to examine the proposed relationships. The results indicate that green innovation and green technology adoption significantly enhance green organizational culture and organizational agility, with Green HRM playing a critical mediating role. However, the direct relationship between green innovation and organizational agility was not statistically significant. These findings suggest that managers should implement Green HRM practices such as sustainability‐focused recruitment, training, and performance management to effectively translate green innovations into cultural and operational agility. This study contributes to the growing body of literature on sustainability and organizational performance by highlighting the importance of integrating green HRM practices with technological and innovative advancements to enhance both organizational culture and agility.
