With the development of social economy and the improvement of people's living quality, transport energy consumption and carbon emissions in China are constantly increasing. At present, China's transport industry has become a key area of energy conservation and emission reduction because of its huge carbon emissions. In this study, we use the input-output method to analyze the carbon emissions caused by energy consumption in transport industry. Combined with the corresponding energy types, the carbon emissions of eight transport activities in 2018 were analyzed from the perspective of structural analysis. Then, this paper studies the relationship between carbon emissions of transport and other industries, and sets up three scenarios to predict the indirect carbon emissions of transport before 2035. The results show that in 2018, the direct and indirect carbon emissions of China's transport industry reached 197313.83 and 217950.38 kt respectively, and the carbon emissions from road transport are the highest among the eight transport activities. Direct carbon emissions caused by diesel oil consumption were the highest, while the indirect carbon emissions caused by coal consumption were the highest. Processing of petroleum, coking and processing of nuclear fuel is the industry most affected by transport activities. Among the twelve components, the spillover one component accounts for the largest proportion. Under SO scenario and TP scenario, it is expected to achieve carbon peak in 2030 and 2025 respectively. The accelerated decline of energy intensity and the adjustment of energy structure are all helpful to reduce indirect carbon emissions.
