By all accounts, electric vehicles are the future. Right now, EV’s comprise a small percentage of the automotive marketplace. A new study from the Ecology Center in Ann Arbor shows the electric vehicles owners are paying far more in taxes and fees and that can serve as a disincentive to purchase. The center’s Charles Griffith joined WEMU’s David Fair for this week’s "Issues of the Environment" to share the study’s findings and discuss the need to create policy that will create tax parity for EV vehicles.
