Driving down non-exhaust particulate matter emissions through new chassis materials and technologies

AutotechInsight Analysis Monthly

Applications of disc coatings, alternative pads, dust collection systems, drag reduction systems, and new tread material compositions are key to achieving reductions in vehicle non-exhaust emissions

While the looming threat of climate change has driven OEMs to prioritize reductions in exhaust emissions through modifications to vehicle propulsion systems, the increasing weight of the average vehicle, partly driven by the progressive move toward drivetrain electrification, has initiated new concerns over rising particulate matter (PM) levels caused by increased wear of the vehicle’s brakes and tires. New developments in particulate testing methodologies have driven regulatory agencies around the world to announce intentions to roll out future standards regulating non-exhaust emissions (NEE) for all new vehicles.
