Electric vehicles can release more pollution than gasoline vehicles, according to a report that has recently resurfaced.
The study, which was published in 2022 but has been circulated again after being quoted in a WSJ op-edfound that brakes and tires release 1,850 times more particles compared to modern exhaust pipes that have filters that reduce emissions.
It found that electric vehicles are, on average, 30 percent heavier than gasoline vehicles, causing brakes and tire treads to wear faster than standard cars and releasing tiny particles. , often toxic, into the atmosphere.
Hesham Rakha, a professor at Virginia Tech, told Dailymail.com that the study is only “partially correct” because, although electric vehicles are heavier, their tires will emit more microplastics into the air, but this could also be true for sedans versus to SUVs.
Electric vehicles may emit more pollution than gasoline vehicles, according to a recently resurfaced report
Rakha said it is very difficult to determine the difference between the amount of microplastics emitted from the tire treads of electric vehicles and gasoline-powered vehicles because you have to separate microplastics already in the air from other sources. with what comes out of the tires.
Rakha and his team at Virginia Tech are conducting field tests to determine how much microplastics electric vehicles and gasoline cars emit by using traffic simulators that will mimic an urban environment.
He added that he doesn’t expect there to be a major difference between electric and gasoline vehicles, and said they haven’t measured it yet, but he expects the difference to be around 20 percent.
This doesn’t mean people should stay away from electric cars because “they are more efficient depending on their zero emissions,” Rakha said, but he added the caveat that “it also generates a lot of CO2 when charging the vehicle.”
Electric vehicle batteries weigh around 453 kg and can generate tire emissions that are almost 400 times greater than tailpipe emissions.
Particulate pollution can increase health problems including heart disease, asthma, lung disease, and in extreme cases can lead to hospitalization, cancer, and premature death.
New gasoline cars are created to be “cleaner”, upgrading the finishes of their internal combustion engines to include particulate filters that reduce emissions.
The increased weight of electric vehicles due to their lithium-ion batteries causes tire treads to wear out faster and ultimately produce more emissions.
He study, Conducted by the firm Emissions Analytics, it said that the main difference between tailpipe emissions and those from tires is that most of the particulate emissions released by the tire go directly to the ground and water, while exhaust gases exhaust negatively affect air quality.
The effects of tire composition come down to the materials from which they are made, the study reported.
Light-duty tires are generally made of synthetic rubber that is developed using crude oil, natural rubber, and added fillers and additives, some of which are recognized carcinogens.
Emissions Analytics tested tire wear on both electric vehicles and gasoline-powered vehicles after driving them at least 1,600 km.
The researchers used a sampling system to collect particles immediately behind each tire and then measured the size of the particles emitted from the tread.
He found that the greater the mass and weight of the vehicle, the more quickly particulate emissions would be released from the tires due to the greater torque between the tires and the road.
A new study revealed that tire wear causes more carbon emissions than an exhaust pipe despite claims that electric vehicles produce no emissions
A seperation 2020 report of the firm Emissions Analytics said tires are likely to be a major concern in the coming years as “consumers opt for larger, heavier cars.”
“Research shows that they contribute to marine pollution from microplastics, as well as air pollution from finer particles,” the report continues.
