Abstract

Abstract

The western region of China is a vital node of the "Silk Road Economic Belt", with significant transportation status and huge pressure on transportation carbon emissions reduction. It is of great significance to deeply study the transportation carbon emission problem in the western region. Firstly, based on the provincial panel data of the transportation industry in the western region from 2000 to 2019, the top-down method was used to calculate transportation carbon emissions, and the spatial and temporal characteristics were described and analyzed by GIS software. Secondly, the LMDI decomposition method was used to explore the influencing factors and effects of transportation carbon emissions. Finally, the Tapio decoupling model was constructed to analyze the decoupling relationship between transportation carbon emissions and the economic development of the transportation industry in the western region. The results showed that:from 2000 to 2019, the total transportation carbon emissions in the western region showed an upward trend, increasing by about 4.6 times, while the overall growth rate decreased. The provinces with the highest transportation carbon emissions were gradually shifting to the southwestern region, and the cumulative increase of transportation carbon emissions in Sichuan ranked first in the western region, reaching 24.1485 million tons of CO₂. Economic scale was the leading factor in promoting the growth of transportation carbon emissions in the western region, and the cumulative contribution rate of transportation carbon emissions was 87.9%, while the carbon emission factor contributes the least, with a cumulative contribution rate of only 4.4%. The energy consumption per unit turnover effect and transportation intensity on transportation carbon emissions were heterogeneous, and the industrial structure had an overall inhibitory effect on transportation carbon emissions. In addition, the overall development direction of the transportation industry in the western region tends to be low carbonization, and transportation carbon emissions and economic development of transportation industry in most provinces has experienced a trend from negative decoupling to expansion connection, and then to weak decoupling. Based on this, it was suggested to formulate a differentiated transportation carbon emission reduction path plan scheme, focus on preventing high carbon emission tendencies in resource-based areas, and strengthen regular monitoring and evaluation of carbon emissions in the transportation industry in the western region.
