Yes, but only to some degree.

Quote from the actual report:

> As the level of electrification of a vehicle rises, the dependence on regenerative braking also increases, thus lowering PM emissions from brake wear. Based on recent evidence [30], regenerative braking can reduce, in the worst- case scenario (i.e. highest usage of mechanical brakes or equivalently lowest usage of regenerative braking), brake wear emissions by 10-48% for hybrid electric vehicles (HEVs), 66% for plug-in hybrid electric vehicles (PHEVs), and 83% for battery electric vehicles (BEVs

This makes sense since vehicles with bigger batteries can absorb more energy with regenerative braking.

I remember decades ago where they figured out the horsepower of a high-end porsche to go 0-100-0, and if the acceleration horsepower expended was 500hp, the deceleration horsepower absorbed by the brakes was probably 1000 hp.

I wouldn't be surprised if hybrids could only absorb 10 hp, while bigger cars could absorb 50.

One thought - if any of these manufacturers provided "braking resistors" like diesel-hybrid locomotives use, regenerative energy could be electrically turned into heat, instead of mechanically by wearing the brakes.

using resistors would be "green".
