Carbon footprint adaptation on green supply chain and logistics of papaya in Yasothon Province using geographic information system

This paper evaluated the carbon footprint of the papaya supply chain to Yasothon Market in Yasothon province, Thailand. There is high consumption of papaya in Yasothon municipality but a lack of papaya plantations in the area lead to a vast amount import of papaya. The study developed a green supply chain and logistics model, using network analysis. The best route for each significant case was the shortest route of the total distance from each registered stop. The results of the analysis revealed that papaya distributed from Ubon Ratchathani and Sisaket Farms should use the route generated by driving and distance impedance with the lowest greenhouse gas emissions at 898.42 kg CO(2)eq./FU. Meanwhile, the distribution from Nakorn Ratchasima should use the driving distance impedance to generate the route with the lowest greenhouse gas emissions at 987.37 k kg CO(2)eq./FU. While the papaya supply chain from Kamphaeng Phet, Kanchanaburi, Lopburi, and Ratchaburi to Khon Kaen Market with driving distance impedance is the best solution among all the alternative routes as it generates the lowest greenhouse gas emissions at 6620.23 kg CO(2)eq./FU. The results suggest that the distribution center can help reducing the distance, resulting in reducing greenhouse gas emissions. The results of the study can suggest the sustainable index of the papaya supply chain by comparing the conventional and improved environmental impact of the papaya supply chain from the green logistics model. The alternatives will be the suggestion of pathways towards improvements in green supply chain and logistics of papaya, which can also be considered for implementation in other agricultural products.
