Purpose: The study examines the influence of socially responsible human resource management (SRHRM) on employees’ voluntary environmental behavior (VEB), and it tests the moderating effect of ecocentric leadership (EL).

Design/Method: We adopted deductive reasoning in a positivist paradigm by applying quantitative analytical techniques and structural equation modeling. We selected 187 respondents from clothing industry through a self-administered questionnaire survey in Chattogram, the commercial capital of Bangladesh.

Findings: The outcomes revealed that both SRHRM and EL influence VEB. However, the moderation analysis indicated that EL negatively intervenes in the effect of SRHRM on VEB.

Implications: One of the essential contributions of our study is its development of the knowledge related to valuing, developing, and measuring SRHRM’s contribution to improving VEB in a moderated model with the help of EL to ensure long-term sustainability.

Originality: Very little is known about the importance of SRHRM in fostering employees’ voluntary environmental behavior, so this study will be one of the first to examine the topic. Moreover, the moderating effect of EL posits that its interaction effect is not substantial in stimulating voluntary environmental behavior if organizations can institutionalize SRHRM.
