Based on the 2024 forecast, climate change-related total tax revenue in the US is projected to show a slight decline in the percentage of total tax revenue, from 2024 to 2028, decreasing from 2.16% to 2.13%. This subtle decrease indicates a consistent downward trend year-on-year, averaging around a 0.5% decline per annum. These values suggest a marginal but steady reduction in reliance on climate-related tax revenues over this period.

Future trends to watch for include:

Policies and regulations that could impact the proportion of climate change-related tax revenue, potentially reversing current trends.
Innovations in clean energy and carbon reduction technologies that might influence tax strategies.
Public sentiment and its impact on legislative changes concerning climate-related taxation.
