The gap between available transportation funding and what’s needed has been growing nationwide. (See C2ES’s brief on federal transportation reauthorization program  for more information.)
States must balance measures to reduce transportation’s effects on the environment, through for example, programs such as electric vehicle incentives, with the need to provide transportation infrastructure funding. Most of this funding comes from user fees including motor fuels taxes. Most of this funding comes from user fees including motor fuels taxes.
Available evidence suggests electric vehicles will have a very small effect on transportation funding in the near term. As a result, the PEV Dialogue Group recommends  that states enact revenue collection plans before electric vehicle adoption noticeably affects revenues, when technically feasible, and without stunting the growth of the electric vehicle market.
This map documents activity by states to recover transportation infrastructure revenue from electric vehicles. Much of the data comes from the Department of Energy’s Alternative Fuel Data Center .
