In order to alleviate the environmental problems caused by high carbon emissions in transportation process, the problem of using multimodal transportation to optimize the route of the postal express enterprises in the transportation process of goods considering environmental tax was studied. Based on hub and spoke transportation network, the transportation cost model was constructed. By adjusting the environmental tax rate in the objective function, the proportion of environmental tax in the total transportation cost was changed. The improved A* algorithm was adopted to solve the problem, and the model was verified by practical examples to obtain the route planning results under different time costs and environmental tax rates, so as to provide corresponding decisions. Example analysis shows that when the time cost coefficient was 5 000 and the proportion of environmental tax was lower than 32%, 32%~78% and above 78%, the optimal schemes were road transportation only, road-water combined transportation and road-rail combined transportation. This shows that a single mode of transportation is suitable for operations with low timeliness requirements. For those operations with high timeliness requirements, multimodal transportation can not only improve transportation efficiency, but also reduce transportation costs.
