Amidst growing concerns about climate change, electric vehicles (EVs) have become a popular choice for environmentally conscious consumers. However, a recent study by Emission Analytics challenges the notion that EVs are inherently better for the environment than traditional gasoline and diesel cars.
Featured in a Wall Street Journal op-ed, the study sheds light on particle pollution from brakes and tires in EVs and fossil fuel-powered vehicles.
Contrary to popular belief, the study suggests that EVs release significantly more particulate matter from brakes and tires than modern gas-powered vehicles equipped with efficient exhaust filters, potentially up to 1,850 times greater.
The concern revolves primarily around tire wear. Emission Analytics highlights that the heavier weight of EVs accelerates tire deterioration, releasing harmful chemicals into the air. This is exacerbated by the fact that most tires are made from synthetic rubber derived from crude oil.
Additionally, the study underscores the impact of battery weight, as EVs typically have heavier batteries than traditional gasoline engines. This extra weight increases strain on the brakes and tires, further contributing to wear and tear.
For instance, the study references popular EV models like the Tesla Model Y and Ford F-150 Lightning, both equipped with batteries weighing around 1,800 pounds.
According to the study, tire wear emissions from an EV with a half-tonne (1,100 pounds) battery could be over 400 times higher than exhaust emissions from a modern gasoline car.
While much attention has been focused on tailpipe emissions, this study emphasizes the importance of considering particle pollution from brakes and tires when evaluating the environmental impact of EVs.
