The Impact of Organizational Environmental Support on Organizational Sustainable Performance: The Mediating Role of Employee Green Behaviour in selected Commercial banks in Batticaloa Region of Sri Lanka

Sustainability is a major global concern and there has been increased pressure on organizations from the stakeholders to broaden the focus of business performance beyond financial performance. Companies should have a balance among financial, social and environmental performance in order to be competitive and survive in the long term. Committed employees are the key asset of every organization and organizations can engage employees in improving their sustainable performance. This paper aims to provide empirical evidence of the associations between organizational environmental support and organizational sustainable performance with the mediating role of employee green behaviour within the selected commercial banks in the Batticaloa Region of Sri Lanka. Data collection was made from 173 employees who are working in commercial banks in the Batticaloa Region of Sri Lanka. Univariate, bivariate, and multi-step mediation analyses have been used to analyze the data. The results indicate that there is a significant positive association between organizational environmental support, employee green behaviour and organizational sustainable performance. It is also concluded that employee green behaviour significantly mediates the relationship between organizational environmental support and organizational sustainable performance. The research concerns the understanding of various environmental support initiatives and sustainable performance from the viewpoint of employees in the banking sector at imparting employee green behaviour as one of the important factors to meet challenges relevant to environmental sustainability in the dynamic banking sector. This study contributes to the field by bringing together the concepts of employee green behaviour with organizational environmental support and organizational sustainable performance in the context of the Sri Lankan banking sector and suggests the banks provide resources and a supportive environment for the employees to implement eco-initiatives.
