The forecast for air pollution-related transport tax revenue in the US from 2024 to 2028 remains stable at 0.41% of tax revenue annually. Given that these values are static, the year-on-year variation and the compound annual growth rate (CAGR) both suggest no change. Without data for 2023, historical baseline comparisons cannot be made.

Future trends to watch:

Potential policy changes or environmental regulations could impact tax revenue.
Innovations in transport technologies might alter air pollution levels, affecting taxation.
Economic shifts may influence the broader tax revenue landscape, altering percentage allocations.
