A study by Emission Analytics has challenged the environmental credentials of electric vehicles sparking significant debate. The study, which gained recent attention through a Wall Street Journal opinion piece, claimed that EVs might be worse for the environment than their gas-powered counterparts, releasing more harmful particles into the atmosphere. Here’s the full story.
Tire and Brake Emissions
According to the Emission Analytics study, the tires and brakes of electric vehicles emit 1,850 times more particulate matter than contemporary gas-powered cars equipped with efficient exhaust filters.
The Source of Pollution
The study pointed out that tire wear has become the primary source of pollution from vehicles today. Light-duty tires, often composed of synthetic rubber derived from crude oil and various additives, disintegrate when heavy electric cars drive on them, releasing dangerous chemicals into the atmosphere.
The Major Factor
The weight disparity between EVs and traditional cars was identified as a significant factor. Electric vehicles, on average, weigh 30% more than their conventional counterparts. As a result, their brakes and tires wear out sooner.
The Discharges
The study indicated that direct exhaust particle emissions from EVs are over 400 times higher than tire wear discharges when accounting for half a metric ton of battery weight. This discrepancy challenged the perception of electric vehicles as a cleaner alternative.
Impact of Battery Weight
The report drew attention to the weight of lithium-ion batteries used in popular electric vehicles. For instance, the Tesla Model Y’s battery weighs a substantial 1,836 pounds, and a similar 1,800-pound battery is found in Ford’s F-150 Lightning pickup truck. According to the study, this added battery weight contributed to increased wear and tear on tires and brakes, further elevating the emissions associated with EVs.
Implications for Biden Administration’s EV Regulations
The study also cast hesitation on the feasibility of the Biden administration’s ambitious electric vehicle regulations, which aimed to make two-thirds of new American automobiles electric by 2032. The administration has been championing electric vehicles as “zero-emissions vehicles.” However, the study challenged this designation, highlighting that petroleum-based tires, which deteriorate and produce particle pollution, are still prevalent in EVs.
The Tradeoff and Climate Change
Nick Molden, the creator and CEO of Emission Analytics, accepted the tradeoff between reducing CO2 emissions, a critical component in combating climate change, and the increase in particle pollution associated with electric vehicles. Molden highlighted that EVs do deliver approximately a 50% reduction in CO2 emissions, aligning with the current political agenda focused on climate change reduction.
The Impact on Health
However, Molden shared the downside of increased particle pollution, noting that air pollution directly impacts human health. The toxins released from tire wear have less impact on climate change compared to their effect on respiratory health and overall well-being.
Public Concerns
The New York Department of Health recently warned that increased exposure to toxins from tire pollution can elevate the risk of health problems such as heart disease, asthma, and low birth weight. Additionally, pollutants from vehicle exhaust, including tire emissions, can travel over long distances and cause health issues even at unhealthy levels.
The Direct Link
Molden stressed the interconnected nature of tire pollution, affecting water and soil, which, in turn, impacts animals. Molden added that as humans consume these fish and animals, they inadvertently ingest tire pollution, creating a direct link between environmental concerns and public health.
