A new study challenges the environmental benefits of electric vehicles. A recent study conducted by Emission Analytics, featured in a prominent Wall Street Journal op-ed, has stirred up the debate surrounding the environmental impact of electric vehicles (EVs) versus traditional petrol and diesel cars.
Contrary to popular belief, the study suggests that EVs might not be as environmentally friendly as commonly assumed, particularly when considering particle pollution stemming from brakes and tires.
The study’s key revelation is that EVs, due to their heavier weight compared to their gasoline-powered counterparts, could potentially emit significantly more particulate matter from brakes and tires.
This unexpected finding challenges the prevailing notion that EVs produce fewer greenhouse gas emissions and underscores the need for a more nuanced understanding of their environmental impact.

One of the primary factors contributing to this disparity is the increased weight of EV batteries. Unlike conventional petrol engines, which are typically lighter, EVs carry bulkier batteries that exert greater strain on braking systems and tires.
As a result, the study suggests that emissions from tire wear in an EV equipped with a half-tonne battery could exceed exhaust emissions from a modern petrol car by a staggering 400 times.
Furthermore, the study highlights the role of tire composition in exacerbating environmental concerns.
Most tires are crafted from synthetic rubber derived from crude oil, and the heightened weight of EVs accelerates tire deterioration, releasing harmful chemicals into the air.
While much attention has been focused on tailpipe emissions in the past, this study underscores the importance of considering the broader spectrum of vehicle emissions, particularly those originating from brakes and tires, when assessing the environmental impact of EVs.
It prompts a reevaluation of the perceived sustainability of EVs as a transportation solution and emphasizes the necessity of comprehensive measures to mitigate their environmental footprint.
The findings of this study are likely to spark further discussion and research into alternative transportation options that strike a balance between environmental sustainability and technological advancement.
As new study challenges environmental benefits of electric vehicles, understanding the full scope of vehicle emissions becomes increasingly critical in shaping effective environmental policies and promoting sustainable transportation solutions.
