The air pollution-related transport tax revenue in Japan is forecasted to decline from 2024 to 2028, reflecting a steady decrease each year. This trend indicates a gradual reduction from an estimated 8.45 billion USD PPP in 2024 to 7.59 billion USD PPP in 2028. The year-on-year reductions highlight a consistent downward trajectory, suggesting diminishing revenue from air pollution-related transport taxes, influenced likely by environmental policies and technological advancements promoting cleaner alternatives.

Future trends to watch for include:

Increased adoption of electric and hybrid vehicles, potentially reducing tax revenue from conventional fuel-related taxes.
Growing emphasis on sustainable urban transport and its impacts on revenue streams.
Potential government policy changes to offset revenue losses from environmental taxes.
