“Ultimately cities will need to reduce vehicle traffic altogether. Much of the most harmful air pollution comes from tyre and brake wear – rather than exhaust fumes. In fact, as Timmers and Achten explain in a 2016 study, non- exhaust emissions already account for over 90% of PM10 (Particulate Matter) and 85% of PM2.5 emissions from traffic. Though hybrid and electric engines have the potential to reduce tailpipe emissions, if the volume of traffic on UK roads remains the same – particle pollution from their tyres will still be present.”
