The forecasted tax expenditure on all fossil fuels for consumers in the UK remains consistently steady at 0.4% of GDP from 2024 to 2028, indicating no year-on-year variation or compound annual growth rate change during this period. This stability suggests a deliberate government policy to maintain tax levels on fossil fuels as a constant proportion of GDP, possibly reflecting a balance between revenue generation and environmental considerations.

Future trends to watch for:

Potential policy shifts due to climate change agreements or international pressure, which could influence fossil fuel taxation.
Technological advancements in renewable energy that may affect fossil fuel consumption and related tax policies.
Economic changes that could impact consumer spending and taxation in the energy sector.
