In 2023, the UK's air pollution-related energy tax revenue stood at a value of about 49.70 USD per capita, PPP=2010. From 2024 onwards, anticipated figures depict a progressive increase, with a year-on-year variation of approximately 5.7% from 2024 to 2025, 4.4% from 2025 to 2026, 3.3% from 2026 to 2027, and 2.6% from 2027 to 2028. The Compound Annual Growth Rate (CAGR) over the five years from 2023 to 2028 is forecasted at 3.8%.

Future trends to watch for:

Impact of evolving environmental policies on tax rates and their potential to accelerate or decelerate revenue growth.
Shifts in industrial sectors towards cleaner energy sources, potentially affecting taxable activities linked to pollution.
Public and corporate response to tax incentives and disincentives aimed at reducing pollution.
