Electric vehicles may release more pollution than gas-powered vehicles, according to a report that has recently resurfaced.
The study, which was published in 2022 but has begun circulating again after being cited in a WSJ op-ed, found that brakes and tires release 1,850 times more particulate matter compared to modern tailpipes which have filters that reduce emissions.
It found that EVs are 30 percent heavier on average than gas-powered vehicles, which causes the brakes and tire treads to wear out faster than standard cars and releases tiny, often toxic particles into the atmosphere.
Hesham Rakha, a professor at Virginia Tech told Dailymail.com that the study is only ‘partially correct’ because even though EVs are heavier, their tires will emit more microplastics into the air, but this could also be true for sedans versus SUVs.
Rakha said it is very challenging to determine the difference between the amount of microplastics emitted from EV tire treads and gas-powered vehicles because you have to separate the microplastics that are already in the air from other sources with what’s coming off the tires.
Rakha and his team at Virginia Tech are in the process of conducting field tests to determine how much microplastics are emitting from EV and gas cars by using traffic simulators that will mimic an urban setting.
He added that he doesn’t expect there to be a major difference between the EV and gas-powered vehicles, saying that they haven’t measured it yet, but expect the difference to be about 20 percent.
This doesn’t mean that people should gravitate away from electric cars because they ‘are more efficient depending zero emission,’ Rakha said, but added the caveat that ‘it also generates a lot of CO2 when charging your vehicle.’
EV batteries weigh about 1,000 pounds, and can result in tire emissions that are nearly 400 times more than tailpipe emissions.
Particle pollution can increase health problems including heart disease, asthma, lung disease and in extreme cases, can lead to hospitalization, cancer, and premature death.
It comes as California is working to impose a complete ban on all gas vehicles by 2035.
New gasoline-powered vehicles don’t release the same amount of emissions as older vehicles, emitting only one percent of all particulate matter (air pollution) in California, with the majority of emissions coming from older vehicles.
New gasoline cars are created to be ‘cleaner,’ by updating the trims of their internal combustion engines to include particulate filters that reduce emissions to below 1/1000th of a gram per mile.
The EVs increased weight due to their lithium-ion batteries cause the tire treads to wear faster, ultimately producing more emissions.
