Emissions Analytics finds pollution from tire wear can be 1,000x worse than exhaust emissions

Green Car Congress

MARCH 8, 2020

Pollution from tire wear can be 1,000 times worse than a car’s exhaust emissions, Emissions Analytics has found. Vehicle tire wear pollution is completely unregulated, unlike exhaust emissions which have been rapidly reduced by car makers due to the pressure placed on them by European emissions standards.
