Regulatory regimes seeking to reduce emissions from transport have largely focused on tailpipe emissions—i.e., the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. earlier post ). Background.
