Non-exhaust Emissions Concern

A new study released by the Paris based Organization for Economic Co-operation and Development states that “non-exhaust emissions will soon overtake vehicle exhaust as the leading source of fine particles released into the air by road traffic.” Non-exhaust particle emissions have been largely ignored by environmental agencies but as electric vehicles become more and more prevalent the need to monitor non-exhaust emissions has become increasingly relevant. Emissions from road traffic consist of airborne particulate matter generated by the wearing down of brakes, clutches, tires and road surfaces, as well as by the suspension of road dust.
