Abstract
Achieving Sustainable Development Goals (SDGs) necessitates environmentally friendly behaviors from all stakeholders, including corporations and their employees. This study investigates the factors influencing Voluntary Environmental Citizenship Behavior (VECB) among millennial employees (Gen Y, born between 1982-2000) within organizations. Drawing on Social Learning Theory, the research examines the impact of various constructs on VECB. Data collected from 969 Indian millennials across diverse demographics was used to test the ‘hypothesized relationships through ‘structured equation modelling’ (PLS-SEM). The study found that Organizational Initiatives for Sustainability (OIS), Employee’s Environmental Commitment (EEC), Employee Engagement initiatives for Sustainability (EES) and employee’s Environmental Self-efficacy (ESE) positively influence VECB of the millennial employees. However, the other two factors studied - Social norms and Consequences - are found to have no impact on VECB, which is contrary to findings in extant literature. Moreover, EEC is found to moderate the relationship between OIS and VECB, suggesting that employees who strongly identify with their organization's environmental values are more likely to engage in voluntary sustainable behaviors beyond formal requirements. Research implications and practical implications of the study findings are also discussed.
