Alternative Fuel Technology adoption could affect long-term state fuel tax revenues with Alternative Fuel Vehicles (AFVs) accounting for 13 percent of the domestic passenger fleet and 11 percent of the commercial fleet by 2040, according to a new study from TTI’s Transportation Policy Research Center. Associate Research Scientist Trey Baker and his team conducted an analysis of Alternative Fuel Vehicle Forecasts that explores trends in the AFV industry, factors impacting AFV adoption, and potential revenue impacts for the State Highway Fund from those trends.
