Research on the Choice of Multimodal Transportation Emission Reduction Schemes Based on Different Carbon Tax Models

Different carbon tax collection methods have an important impact on the emission reduction effect of multimodal transportation. In the entire chain transportation process of containerized cargo multimodal transportation, the generalized external cost is considered to establish the total utility model of multimodal transportation. Based on the optimal carbon tax rate, we studied the impact of single tax rate and progressive tax rate on carbon emissions of multimodal transportation schemes. Also, the Tianjin-Weihai section of the Bohai Rim Economic Circle is used for example analysis. The results of the study found that under different carbon tax starting points, the cost of electronic goods can be reduced by 80-200 yuan per ton, and the carbon emissions can be reduced by 350-600 tons. The effect of reducing emissions is also different for different cargo values. By adjusting the structure of cargo transportation, an optimal multimodal transportation plan considering carbon tax is proposed to provide a basis for carbon tax policy formulation and implementation.
