Climate change is the biggest concern nowadays; every-one is focusing on how they can contribute to saving the planet. This work will focus on green supply chain management (GSCM); it can define as a concept which includes various processes like product design, manufacturing and production techniques, operations, material selection, waste management and many more as a step to prevent environmental catastrophes. This work identified various barriers to implementing GSCM and found interrelations between them. Finally, based on these barriers developed the ISM model which will be further helpful in eliminating or reducing waste and also improving the economic and environmental performance of the industry. In this study, lack of awareness about reverse logistics and lack of human resources are identified most significant barriers.
