Environmental Impacts of Tire Particles from Electric Vehicles
The increasing adoption of electric vehicles (EVs) has raised concerns about a lesser-known environmental issue: tire particle pollution. These pollutants come from the wear and tear of tires, which is exacerbated by the characteristics of EVs.
Key Factors Contributing to Higher Pollution
- Weight and Acceleration: Electric vehicles are generally heavier than petrol or diesel cars due to their large batteries. This increased weight, combined with the aggressive torque (rapid acceleration) typical of EVs, leads to faster tire wear and higher emissions of particulate matter.
- Particulate Matter Emissions: Tire wear from EVs results in the release of tiny nanoparticles into the atmosphere. Studies suggest that EVs emit up to 20% more particulate matter than comparable gasoline vehicles.
Health and Environmental Concerns
- Health Impacts: Particulate matter from tire wear has been linked to various health issues, including heart, lung, developmental, reproductive, and cancer outcomes.
- Environmental Pollution: Tire particles contribute to microplastic pollution in oceans and other water bodies. It’s estimated that 200,000 tons of tire particles end up in oceans annually.
- Lack of Regulation: Unlike exhaust emissions, tire and brake pollution have not been as heavily regulated, partly because they are harder to measure and control.
Current Research and Findings
- Research indicates that particulate matter pollution from tires can be significantly higher than that from exhaust emissions, especially in regions with well-controlled tailpipe emissions.
- The transport sector is seeing a rise in EVs, with over 14 million on the road, contributing to increased tire pollution globally.
Overall, while electric vehicles offer numerous environmental benefits by reducing greenhouse gas emissions, their tire pollution contributes to ground-level air pollution and environmental degradation, requiring further study and regulation.
