The forecast for the air pollution-related total tax revenue in the UK, from 2024 to 2028, is consistently 0.54% of GDP annually. This suggests no expected year-on-year variation over the forecasted period. The steady tax revenue indicates no significant policy changes or economic fluctuations affecting this tax segment in the medium term.

Future trends to watch for include:

Potential regulatory changes impacting environmental taxation that could alter revenue forecasts.
Economic growth or recession that may indirectly influence air pollution tax collection.
Technological advancements that significantly reduce pollution levels and thus lower associated tax revenues.
