The forecast for Germany's air pollution-related energy tax revenue indicates a gradual decline between 2024 and 2028, measured as a percentage of GDP. Starting from 1.05% in 2024, it is predicted to decrease steadily to 0.97% by 2028. The year-on-year variation shows a consistent negative trend, highlighting a contraction over the forecast period.
Future trends to watch include potential policy shifts towards renewable energy subsidies and possible changes in the taxation structure aimed at reducing emissions. Economic factors, such as changes in GDP growth or technological advancements in non-polluting energy sources, could also impact these forecasts.
