Abstract The globalization of the economy and trade has made the transportation industry flourish, and the traffic demand is growing. Under this trend, energy consumption is increasing and environmental pollution is becoming more and more serious, so the development of “low-carbon transportation” is inevitable. Intermodality is a green transportation method that reduces transportation costs, shortens transportation time, improves transportation quality, reduces road congestion and is environmentally friendly. It can reduce carbon emissions and noise pollution while improving energy efficiency. Therefore, strengthening the use of intermodality can significantly reduce carbon dioxide emissions, thereby reducing the greenhouse effect. In the present study, carbon emissions are added to the intermodality route study, and an intermodality path selection model in a low-carbon environment is established. Through the use of genetic algorithms and step-by-step method to solve this problem, we find the best low-carbon transportation methods and routes. It has practical application value, enabling decision makers to balance the economic interests of the company while making decisions and to meet the government’s carbon dioxide emission limitations.

1 Introduction Greenhouse gases [1] absorb solar radiation reflected from the ground and reemit infrared radiation [2, 3] because the most important gas of greenhouse effect is carbon dioxide. Therefore, carbon is used as a unit of measurement for greenhouse gases because different greenhouse gases have different effects on global warming. The impact of the basic unit of the greenhouse effect is determined by the use of carbon equivalents. The basic form of carbon accounting is the carbon footprint, which is a combination of greenhouse gas emissions caused by a company’s institutions, activities, products or individuals. It can be used to measure the amount of carbon dioxide produced or the unit of carbon responsible for emissions. The carbon emissions studied in the present research work refer to the carbon dioxide emitted during transportation, which belongs to the category of direct carbon emissions [4]. Carbon emissions are greenhouse gases that are released into the atmosphere of a particular area over time. Carbon emissions and carbon solidification are two opposing processes. Carbon emission rights, i.e., greenhouse gas emission rights, refer to the total amount of greenhouse gases emitted during energy consumption, includin
