In 2023, environmentally-related pollution tax revenue in the UK stood at approximately 873.24 million US dollars. Forecasts for 2024 to 2028 indicate a consistent downward trend in revenue, with a year-on-year decline from 2024's 810.46 million US dollars to 563.07 million US dollars by 2028. This reflects a compounded annual growth rate (CAGR) of approximately -8.8% between 2023 and 2028.

Future trends to watch for:

Increased regulatory pressure may further incentivize reductions in pollution levels, impacting tax revenues.
Adoption of cleaner technologies could accelerate revenue decline or shift revenue streams.
Economic factors and policy changes may alter the trajectory of pollution-related tax structures.
