The forecasted air pollution-related tax revenue in Germany, expressed as a percentage of GDP, shows a slight declining trend from 2024 to 2028. Post-2023, where the figure stood unchanged, the annual percentage decreases reveal a gradual reduction in tax revenue. Specifically, from 2024 to 2028, there is a consistent year-on-year decline, indicating a tapering trend in the revenue's contribution to the national GDP. The Compound Annual Growth Rate over these years reflects this declining pattern. Such trends suggest the need to monitor adjustments in air quality policies, technological advancements in emissions controls, and shifts in energy sources which could impact future tax dynamics.
