The forecast for air pollution-related transport tax revenue in France from 2024 to 2028 is expected to remain stable at 2.45% of the environmental tax revenue each year. This suggests no anticipated variation over the five-year period, indicating a flat growth trajectory.

Trends to watch include potential policy changes aimed at reducing air pollution, which could affect transport tax policies. Additionally, shifts in transportation technology and energy sources, such as the rise of electric vehicles, may influence future tax revenues.
