In 2024, the forecasted climate change-related transport tax revenue in Japan is set to rise from its level in 2023, starting at 2.44. The annual increase is anticipated to be steady, rising to 2.57 in 2025 and reaching 2.83 by 2028. This reflects a consistent upward trend that can be largely attributed to Japan's ongoing efforts to address climate change through fiscal measures related to transport.

Future trends to watch for include:

The impact of emerging transportation technologies on tax revenue streams.
Changes in government policies related to carbon emissions and sustainable transportation.
The influence of global climate agreements on Japan’s transport-related taxation strategies.
