Transportation systems are vital links for intercountry. However, the transportation industry is associated with high energy consumption and carbon emissions. In this paper, the transportation carbon efficiency (TCE) across the Belt and Road Initiative (BRI) countries during 2005–2017 is estimated by modifying a three-stage epsilon-based measurement model, and the carbon emission reduction potential (CERP) is identified. Based on the results, countries are classified into four categories by comparing a country's TCE and CERP with the average of all BRI countries. The results show that the average TCE of BRI countries is only 0.341, while their average CERP is 0.75, which is tremendous. It also shows that the higher the income levels, the more prone countries are to have a higher TCE. By considering the differences among the countries' environmental factors, TCEs, and the current state or trends of the CERPs, customized low-carbon policies are proposed to increase the TCE and reduce emissions.

估算“一带一路”沿线国家的交通碳效率(TCE):一种基于改进的三阶段 epsilon 测量模型的综合方法

交通系统是国家间的重要纽带。然而,运输业与高能耗和碳排放有关。本文通过修改基于 epsilon 的三阶段测量模型估算了 2005-2017 年“一带一路”沿线国家的交通碳效率(TCE),并确定了碳减排潜力(CERP) . 根据结果​​,通过将一个国家的 TCE 和 CERP 与所有 BRI 国家的平均值进行比较,将国家分为四类。结果表明,“一带一路”沿线国家的平均TCE仅为0.341,而其平均CERP为0.75,非常惊人。它还表明,收入水平越高,国家越倾向于拥有更高的 TCE。考虑到各国之间的差异
