The objective of this paper is to design an environmentally-friendly supply chain (efSC) network by efficiently regulating CO2 emission amount resulting from transportation process of materials or products. For designing the efSC network, a mathematical formulation considering various transportation types (i.e., normal delivery, direct delivery and direct shipment) is suggested and implemented using hybrid genetic algorithm (pro-HGA) approach. In numerical experiment, the performance of the pro-HGA approach is compared with those of other conventional approaches, and the efficiency of the efSC network is also compared with that of the SC network not regulating CO2 emission amount under various measures. Finally, it is proved that the performance of the pro-HGA approach is superior to those of the others and the efSC network outperforms the conventional SC network.
