But the energy would have been dissipated in the brakes and heat is used to charge the batteries.

The study claims that the "pollutants" are particulates from tire wear (rubber) and brake wear (asbestos, among other things).

Yes, you are correct: the energy dissipated by the brakes is instead used to recharge the batteries. So, the particulates from brakes should actually be REDUCED.

And brakes should last longer. ;)
