In the contemporary BANI (Brittle, Anxious, Nonlinear and Incomprehensible) world, organisations face increasing pressure to advance not only economic objectives but also social and environmental sustainability. While many organisations institutionally support environmental sustainability, the sustainability cause demands going beyond structural policies and green initiatives. The efficacy of environmentally responsible policies frequently depends on the pro-environmental behavior of individual employees. Among the various organisational factors that may affect pro-environmental behavior, employees’ perception of organisational politics can play a significant role in influencing how employees engage with environmental initiatives. Furthermore, the emotional climate of the workplace such as experiences of loneliness may further affect employees’ willingness to contribute to sustainability initiatives. Guided by Social Exchange Theory, this study explores how perceptions of organizational politics influence pro-environmental behavior. Multi-wave data was collected from employees in the hospitality industry in India. The results from the moderated regression analysis indicate that perception of organisational politics has a significant negative effect on pro-environmental behavior. Furthermore, the interaction effect is significant, interestingly, workplace loneliness significantly moderates this relationship by weakening the negative relationship between politics and pro-environmental behavior. Workplace loneliness also shows a negative relationship with pro-environmental behavior. Theoretical contributions and practical implications are also discussed.
