Electric cars produce less brake dust pollution than combustion-engine cars
“It’s not just the tailpipe y’all,” joked one Electrek commenter, alluding to the black discolorations on alloy wheels visible proof of a less infamous city pollutant: brake dust. For d…
A trailblazing study by EIT Urban Mobility, surveying the busy streets of London, Milan, and Barcelona, has quantified a colossal 83% reduction in brake dust pollution from battery-electric cars compared to their combustion-engine counterparts. Studies using human alveolar cells have shown that copper-enriched brake dust initiates extreme oxidative stress and inflammation at times equalling or even surpassing the effect of diesel exhaust particles. The EIT Urban Mobility report also refers to the bigger picture: moving commuters out of private cars and into public transport, cycling, or walking can achieve up to five times more reduction in non-exhaust emissions than individual electrification.
