This study contributes by revealing the unified and diverse peak patterns of three core TCE indicators at national levels, while addressing a critical gap in global emission reduction strategies through cross-economy analysis. The findings confirm a predictable evolution in TCE across most nations but highlight significant variations between developed and developing economies. The prolonged duration of Stage II compared to Stage III suggests a more challenging transition phase for many countries. Moreover, the limited influence of standard socioeconomic metrics on stage durations emphasizes the need for nuanced, country-specific approaches to emissions transitions. The study proposes targeted TCE reduction measures differentiated by development stage and transportation sub-sector, providing scientific guidance for policy formulations.
