Electric vehicles (EVs) significantly reduce brake wear, a major source of non-exhaust emissions (NEEs) in urban areas. A recent report highlights that regenerative braking in EVs can cut brake wear by over 80%. This leads to substantial improvements in air quality by reducing particulate matter (PM) emissions.
NEEs, including particles from brake, tire, and road wear, are a dominant source of urban PM. Brake wear is the primary contributor to NEEs in cities like London. While EVs increase tire wear due to their weight, the overall impact of fleet electrification is positive.
Upcoming Euro 7 regulations will limit brake wear emissions, with tire wear limits to follow. Cities should integrate NEEs into air quality strategies and promote public transport. Reducing reliance on private vehicles through modal shifts can significantly cut NEEs.
