Purpose This study aims to investigate how employee environmental performance (EP) is affected by socially responsible human resource management (SRHRM) via green knowledge sharing (GKS) and environmental commitment (EC). Design/methodology/approach Partial least squares-structural equation modeling was used to analyze data from 494 frontline employees of hotels. Findings The findings reveal that SRHRM influences employee EP, GKS and EC. SRHRM indirectly predicts individual EP through GKS and EC mediation. GKS and EC also have significant relationships with employee EP. Practical implications Hotels can use the findings of this study to develop effective strategies to promote employees’ positive responses to the environment and improve their organizational identification. Moreover, the current research enables the organization to recognize the importance of employees’ GKS and EC and capitalize on them. Originality/value This study links SRHRM to the individual EP level in the hotel industry. This study reveals the importance of EC and GKS as psychological mechanisms linking SRHRM and EP.
