Purpose: This study aims to examine the relationship between employees’ mindfulness and pro-environmental behaviour, along with the mediating role of self-transcendent values, at the workplace.

Design/methodology/approach: The study uses online data collected from 381 respondents employed in different industries across India. Confirmatory factor analysis was used to check the construct’s validity and reliability and Pearson correlation was used to examine the relationship between the variables. Moreover, the PROCESS macro of Hayes (2017) was used to examine the mediation.

Findings: Employees’ mindfulness was found to be positively associated with voluntary pro-environmental behaviour at the workplace, and the mediation analysis specifies that a self-transcendent value partially mediates this relationship.

Research limitations/implications: This study tested and extends the S-ART model and Schwartz value theory in the context of employees’ pro-environment behaviours at the workplace.

Practical implications: The results could be encouraging and helpful for top management and organizational change champions in strategizing and effective implementation of mindfulness programmes that would encourage and enhance employees’ voluntary participation in environment-friendly activities at their workplace.

Originality/value: Despite the decisive role of employees in organisations’ environmental sustainability programmes’ success, the availability of scant literature has led researchers to call for more studies. The present study is timely and could be the first to examine the role of employees’ mindfulness and self-transcendent values in influencing employees’ engagement in environmental-friendly behaviours at the workplace.
