Taking Shandong Province as an example, this paper uses the “top-down” method to calculate the carbon emissions of the transportation industry in Shandong Province from 2014 to 2022, and constructs an LMDI model to decompose the driving factors of transportation carbon emissions and identify significant influencing factors. The results show that from 2014 to 2022, the carbon emissions of Shandong’s transportation will increase first and then decrease due to the impact of the epidemic, of which gasoline and diesel energy consumption will account for 10% and 43% respectively. Energy structure, energy intensity and industrial structure inhibit the increase of carbon emissions of the transportation industry in Shandong Province, and economic output and population size play a role in promoting the increase of carbon emissions of the transportation industry in Shandong Province. To achieve the carbon peak goal, Shandong Province needs to take proactive measures to reduce carbon emissions from the transportation sector.展开更多
