Abstract

Purpose: Grounded in social cognitive theory, this study aims to investigate how workplace spirituality influences pro-environmental behavior. Specifically, it examines the mediating role of psychological green climate in this relationship and explores the extent to which ethical leadership moderates this mediation effect. Design/methodology/approach: A cross-sectional survey design was employed, collecting data from 577 employees in the service sector industry from Jammu and Kashmir, India. The study utilized structural equation modeling through AMOS and SPSS to test the hypothesized relationships. Findings: The findings reveal that workplace spirituality serves as a foundational driver of pro-environmental behavior. Additionally, psychological green climate emerges as a critical mediator. The study also confirms a moderated mediation effect, indicating that ethical leadership amplifies the mediating influence of psychological green climate. Originality/value: This study advances the literature by offering a nuanced understanding of how workplace spirituality fosters pro-environmental behavior through psychological green climate, positioning ethical leadership as a vital contextual force in shaping these dynamics. The results underscore the necessity for organizations to cultivate ethical leadership and a psychologically green climate to maximize the sustainability-driven impact of workplace spirituality. © 2025, Emerald Publishing Limited.
