The forecast for tax expenditure on coal for general services in Germany shows a consistent figure of 0.001% of GDP from 2024 to 2027, before dropping to zero in 2028. This suggests a stable but minimal contribution of coal tax expenditure relative to GDP in the near term, followed by a complete phase-out. The absence of year-on-year variation and the five-year CAGR underscores the stable nature of coal's role in general services before its predicted removal.

Future trends to watch for include:

Progress in renewable energy adoption and its impact on coal usage.
Government policy changes affecting tax structures related to fossil fuels.
Adaptations within general services to new energy sources as coal expenditure ceases.
