A study from the University of Edinburgh shows that electric and hybrid vehicles emit as many, if not more, atmospheric toxins than fossil fuel-burning vehicles.
The study, conducted by Victor Timmers and Peter Achten at the University of Edinburgh, and published by the journal Atmospheric Environment, found that heavier electric vehicles produce as many pollutants as their lighter weight conventional vehicles.
Electric vehicles tend to produce more pollutants from tire and brake wear, due in large part to their batteries, as well as the other parts needed to propel them, making them heavier.
These pollutants are emitted when electric vehicle tires and brakes deteriorate as they accelerate or slow down while driving. Timmers and Achten’s research suggests exhaust from traditional vehicles is only about one-third of the total emissions.
Further, the particulate matters are worse than fuel emissions, because they cause more health problems.
“We found that non-exhaust emissions, from brakes, tires and the road, are far larger than exhaust emissions in all modern cars,” Achten wrote in the study.
