Abstract
Academic research indicates that Bangladesh has relatively low levels of employee green behaviour. Developed and developing nations worldwide have raised environmental awareness within their workforces in response to the alarming rate of environmental deterioration caused by human activities. This study looks into potential links between the motives (intrinsic and extrinsic), green behaviour, and attitudes of Bangladeshi employees. A theoretically supported framework has been developed using self-determination theory. Purposive sampling was used for this survey on Bangladeshi financial institutions (private banks). Data were analyzed using partial least squares based structural equation modeling (PLS-SEM). The findings propose that employee green attitude mediates the relationship between intrinsic motivation and employee green behaviour. Employee green attitude (EGA) also mediates the relationship between employee green behaviour (EGB) and introjected, identified, integrated, and external regulation (external motivation). The outcomes display a negative relationship between introjected regulation and employee green behaviour as well as external regulation and employee green behaviour, contradicting other research. In Bangladesh, EGA and EGB are understudied; therefore, this research has significance. This research will assist the international community in addressing environmental, social, and economic concerns for a more sustainable future.
