Abstract: Controlling greenhouse gas emissions across the supply chain network is a significant issue for businesses today. However, the complexity of green supply chain concerns makes it crucial to present a model that can be effectively addressed. In this research, factories, warehouses, and retailers are investigated as a three-level supply chain network. The proposed model seeks to reduce the overall cost of the system while also cutting down on gas emissions. With this model, we propose using the multi-objective goal programming approach as a solution technique. Results from the epsilon constraint approach and the sensitivity analysis of the required parameters have been compared to validate the efficacy of the suggested method. According to the findings, the amount of pollution generated by each facility is proportional to the requested quantity, and the travelled distance of vehicles.
