This paper presents a framework for calculating an integrated index to assess the sustainability of the supply chain of a given product. Analytical Hierarchy Process (AHP) has been used to obtain relative weights of the different indicators and dimensions of sustainable development context. This framework considers all entities involved in the supply chain and provides an integrated index to evaluate supply chain movement towards a more sustainable environment. Plastic carrier bags supplied by a large supermarket chain, Shahrvand, is chosen as a case study. An integrated index of sustainability is presented for plastic carrier bags supply chain in two periods of time. Interpretation and sensitivity analysis of results is given and effectiveness of integrated index is pointed out.
