Green supply chain management (GSCM) has become a practical approach to develop environmental performance. Under strict regulations and stakeholder pressures, enterprises need to enhance and improve GSCM practices, which are inluenced by both traditional and green factors. his study developed a causal evaluation model to guide selection of qualiied suppliers by prioritizing various criteria and mapping causal relationships to ind efective criteria to improve green supply chain. he aim of the case study was to model and examine the inluential and important main GSCM practices, namely, green logistics, organizational performance, green organizational activities, environmental protection, and green supplier evaluation. In the case study, decision-making trial and evaluation laboratory technique is applied to test the developed model. he result of the case study shows only “green supplier evaluation” and “green organizational activities” criteria of the model are in the cause group and the other criteria are in the efect group. 1. Introduction Environmental protection is becoming more and more important for enterprises because of stronger public aware- ness, competitors and communities, and government regula- tions. For this purpose, some programs become more popular for environmentally aware performing including total quality environmental management, ISO 14000 standards, and green supply chain management. Reducing the environmental pollution from upstream to downstream during procuring raw materials, producing, distribution, selling products, and products depreciation is the most important goal of green supply chain management (GSCM). Indeed, there is no research that determines main factors in a whole green supply chain system or specify their power of inluence on each other to ind their role in a system. his study ills this gap by presenting a model that consists of ive main practices to improve GSCM by selecting green supplier. Supplier selection is a fundamental issue of supply chain area which heavily contributes to the overall supply chain performance [1]. Suppliers’ development is a critical function within supply chain management. Green supplier improvement is also essential for efective green supply chain management. Supply Chain managers could minimize the products’ environmental impact based on some related environmental criteria. It harmonizes the economic, customer value, man- ufacturability, and other factors that may also be evaluated. Additionally, buyer-supplier relations play an increasingly important role in addressing environmental issues. he third concern is that irms should change their environmental performance methods in order to incorporate environmental concerns of external sources. herefore, a system analysis is needed to integrate environmental management with the greening of the supply chain. Supply c managers must consider the complete environmental impact of a product during its entire life cycle, including raw material, manu- facturing/assembly processes, distribution, use, and disposal. he environmental efects include material, energy, air, water, and solid waste pollution [2]. he main and basic challenges in the green supply chain are modeling a strategy to manage the resources and meet the demands [3]. Select the green suppliers that will deliver the goods and services that are required to manufacture the
