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 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 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 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.

利用地理信息系统对益梭通省木瓜绿色供应链和物流进行碳足迹适应


本文评估了泰国也梭通府也梭通市场木瓜供应链的碳足迹。也梭通市的木瓜消费量很高，但该地区缺乏木瓜种植园，导致木瓜大量进口。该研究利用网络分析开发了绿色供应链和物流模型。每个重大案例的最佳路线是距每个注册站点总距离的最短路线。分析结果显示，乌汶府和四色菊农场配送的木瓜应采用由行驶和距离阻抗产生的路线，温室气体排放量最低，为 898.42 kg CO eq./FU。同时，从呵叻出发的分布应使用行驶距离阻抗来生成温室气体排放量最低（987.37 k kg CO eq./FU）的路线。而从甘烹碧府、北碧府、华富里府和叻丕府到孔敬市场的木瓜供应链（具有行驶距离阻抗）是所有替代路线中的最佳解决方案，因为它产生的温室气体排放量最低，为 6620.23 千克二氧化碳当量/FU。结果表明，配送中心有助于缩短距离，从而减少温室气体排放。研究结果可以通过比较传统的和改进的绿色物流模型对木瓜供应链的环境影响，提出木瓜供应链的可持续指数。替代方案是提出改善木瓜绿色供应链和物流的路径建议，也可以考虑在其他农产品中实施。
