The emissions growth rate differs significantly between high-income and low- and middle-income Asian economies. The share of high-income economies in total transport CO2 emissions decreased from 36% in 2000 to 16% in 2022, suggesting their emissions growth intensity has been comparatively lower than that of upper and low- and middle-income economies.

Within Asia, distinct sub-regions have followed different growth trajectories. Transport-related carbon emissions surged between 2000 and 2018, then plateaued around 2018, with further disruptions from the COVID-19 pandemic. However, by 2023, the transport sector in most sub-regions had fully recovered and even surpassed 2018 levels, except for the Pacific sub-region.
