As the automotive industry continues its transition towards electric mobility, concerns over the environmental impact of electric vehicles (EVs) have come under scrutiny. A recent study conducted by Emission Analytics reveals that EVs contribute to higher particle pollution through tyre wear than their ICE counterparts. Here are some notable highlights from the study: –
- The study suggests that EVs’ heavier weight compared to their modern internal combustion engine (ICE) counterparts may lead to accelerated tyre wear, releasing up to 1,850 times more harmful particulate matter into the air.
- This is concerning as EVs’ heavier weight accelerates tyre deterioration, releasing harmful chemicals into the air, primarily due to synthetic rubber tyres derived from crude oil. Crude oil is processed to produce various chemicals, including synthetic rubber, which is one of the key components used in tyre manufacturing.
- The study also underscores the influence of battery weight. Electric vehicles (EVs) often feature heavier batteries in contrast to traditional petrol engines. This additional weight places increased stress on brakes and tyres, quickening their wear and tear.
- According to the study, emissions from tyre wear in an EV equipped with a half-tonne (1,100 pounds) battery could exceed exhaust emissions from a modern petrol car by over 400 times.
- While we usually think about emissions coming out of the tailpipe, this study tells us we should also pay attention to pollution from brakes and tyres when assessing the environmental impact of electric vehicles (EVs).
In conclusion, this study emphasizes the importance of considering all sources of pollution, including those from brakes and tyres, when evaluating the environmental impact of electric vehicles. By recognizing the significance of particle emissions beyond tailpipe exhaust, we can better understand and address the challenges and opportunities associated with transitioning to electric mobility.
