This study examined the impact of green human resource management (GHRM) and green supply chain management (GSCM) on the economic, social, and environmental performance of 272 (ISO-certified) textile firms in Pakistan. It investigated how a firm's size and the number of years since adopting GSCM practices influence performance. Survey data were collected from these firms through a cluster sampling approach and then analyzed through structural equation modeling. Results highlighted that GHRM positively influences a firm's environmental and social performance. Results further indicated that inbound and outbound GSCM activities mediate between GHRM and a firm's environmental and social performance. The moderation results revealed that a firm's size is crucial for improving performance. From an emerging economy perspective, this study draws the attention of policymakers and managers, concluding that implementing GHRM improves the green orientation of all the departments within a firm and helps organizations achieve sustainability goals.
