The forecast for air pollution-related transport tax revenue in the US, expressed as a percentage of GDP, remains stable from 2024 to 2028 at 0.12%. This indicates a lack of variance and implies a relatively unchanged fiscal impact from this specific tax over the forecast period. There is no calculated year-on-year variation due to this stability, showing a consistent trend over the years. The five-year compound annual growth rate (CAGR) is effectively zero, reflecting no anticipated growth or decline in the percentage of GDP attributed to this revenue.
Future trends to watch for include potential changes in government environmental policy, technological advances in transportation reducing emissions, and economic fluctuations impacting GDP. Monitoring these factors will be crucial in anticipating any shifts in air pollution-related transport tax revenue.
