Energy issue is one of the crucial problems in the corresponding research of sustainability because it is strongly related to the environmental dimension and economic dimension. For evaluating the transport sustainability level for sustainability for regions, the concept of sustainable achievement efficiency in transport energy consumption is initially suggested in this article. And then, on the quantitative analysis to calculate the transport energy achievement efficiency of the regions, the indicators that can represent the achievement of transport energy consumption are convincingly found out by indicator theory. Next, concentration is focused on the transport related indicators and proper indicators are picked up from the candidate indicators, which were the affecting factors to this issue. After that, using the selected indicators, we introduce the method of data envelopment analysis to do quantitative analysis, which helps to get the sustainable achievement efficiency of transport energy among cities all over the world. The analysis result shows the efficient regions and the inefficient regions respectively. Furthermore, the detailed efficiency value of each region is also laid out clearly. Consequently, the achievement efficiency in transport sector can be discussed quantitatively and further policy implications can be suggested for improvement for the inefficient regions to reach high level sustainability.
