The forecast for climate change-related total tax revenue in the U.S., expressed as a percentage of GDP, shows a slight downward trend from 2024 to 2028. The constant values of 0.51% to 0.5% signify minimal year-on-year decreases. This consistent decrease results in a negative compound annual growth rate (CAGR) over five years, reflecting a gradual decline in the relative share of this revenue stream in GDP.
Future trends to watch for include policy changes impacting carbon taxation, economic shifts affecting GDP figures, and any emerging technologies that could influence emissions and subsequently tax revenues.
