Employees’ Intentions to Engage in Green Practices: A Multilevel Extended Theory of Planned Behavior Perspective

In recent years, organizations have increasingly promoted and integrated employees' environmentally sustainable behaviors and practices as part of a strategic approach to enhance corporate reputation, demonstrate environmental stewardship, and respond to pressing ecological imperatives. This study explores the psychological factors that motivate employees' intentions to engage in green behaviors within organizational settings, following the Theory of Planned Behavior (TPB). We extend the model by incorporating a conceptually multilevel perspective, examining antecedents at the organizational, team, and employee levels: perceived organizational support, perceived colleague support and workplace attachment. Data were collected from a sample of 286 public employees. Our findings indicate that, among the behavioral antecedents proposed by the TPB, only some were validated as significant predictors of employees' intentions to engage in green behaviors within their organization. The results further show that each organizational, team, and employee level antecedent included in this study significantly influenced the constructs of the TPB. Implications and suggestions for future research are also discussed.
