With the ever-increasing environmental pollution and its harmful consequences, alongside the consequent increase in demand for environmental products and services for environmentally-friendly products and services, one should try to reduce the pollution caused by industrial expansion in an attempt to run a green supply-chain management. Thus, this study identified and determined the drivers of implementation of the Green Supply Chain Management and determined the relationship between them and leveled them to encourage the steel industry to implement green supply chain management. The proposed model is obtained based on the use of the Structural Interpretative Modeling Method. The results of the stimulus relationship model show that the “government, rules, and regulations,” as the most effective stimulus, are the source of implementation of green supply chain management in Mobarakeh Steel Complex. Keywords: Green supply chain management, organizational stimulus, structural interpretation modeling.
