The primary aim of this study is to investigate how employees' corporate social responsibility (CSR) perceptions contribute to their voluntary pro‐environmental behaviors. This study also seeks to understand the moderating effects of employees' CSR motive attribution (substantive and symbolic) on the relationship between CSR perceptions and voluntary pro‐environmental behaviors. A questionnaire survey was conducted on 784 employees working in various industries such as telecommunication, pharmaceutical, medical, manufacturing, hospitality, and electronic. Results revealed that CSR perceptions positively affected voluntary pro‐environmental behaviors of employees. Moreover, employee's substantive CSR motive attribution strengthened the positive effect of CSR perceptions on voluntary pro‐environmental behavior, whereas symbolic CSR motive attribution weakened the positive effect of CSR perceptions on voluntary pro‐environmental behavior. This study provides guidance for managers who wish to address sustainability and CSR issues to enhance employees' voluntary pro‐environmental behavior. Organizations should integrate CSR initiatives into their sustainable strategy to increase employee's voluntary pro‐environmental behavior.
