Air pollution-related energy tax revenue in the UK is forecasted to remain stable at 0.11% of GDP from 2025 to 2028, demonstrating negligible year-on-year growth following an initial increase from 0.1% in 2024. This indicates a steady policy or demand environment affecting this fiscal domain. The compound annual growth rate over this period reflects minimal change.

Future trends to watch for include:

Potential shifts in government policy, which could alter energy taxation dynamics.
Technological advancements in clean energy that may impact tax structures and revenue.
Economic shifts that could affect GDP and thus alter the revenue as a percentage of GDP.
