In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions (earlier post). Since that study, which was transparently designed to quantify the worst-case tire emissions under legal driving, Emissions Analytics has been testing and analyzing... Read more →


The Audi Environmental Foundation is developing filters for urban runoff in conjunction with the Technical University of Berlin (TUB). The filters prevent tire wear particles and other environmentally harmful substances from being washed into sewers and bodies of water along with rainwater. Initial field and lab tests have now demonstrated... Read more →


Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. Recently, this substance has been linked to massive die-offs of coho salmon across the US West Coast. Now, researchers in Canada report that exposure to 6PPD-quinone at environmentally... Read more →
