Impact of green supply chain management on financial and environmental performance: mediating role of operational performance and the moderating role of external pressures

Green supply chain management (GSCM) practices are considered as vital practices in tackling environmental issues faced by firms. This study examines the relationship between GSCM, environmental and financial performance of firms. Further, the study examines the mediating role of operational performance between the relationships of GSCM-environmental performance and GSCM-financial performance. Additionally, the moderating role of external pressures (regulatory and customer pressures) has been examined on the relationship of GSCM and operational performance. Methods: Data from 277 executives working in different industries of Pakistan (where GSCM practices have been adopted) has been collected for the study. Results: The results of the mediated regression analysis confirm the partial mediation of operational performance between GSCM, environmental and financial performance. The results of moderated regression analysis confirm that presence of external pressures enhances the relationship between GSCM and operational performance. Conclusions: These results suggest that the adoption of GSCM practices in Pakistan can be fruitful for the companies. Mandatory requirement by regulatory authorities can also be helpful in adoption of the GSCM practices which ensure environmental performance of firms and consequently the betterment of overall environment.
