From your link > Take for example our DiscCover coating solution: authorities worldwide have introduced stringent limits for exhaust emissions — including NOX, CO2 and particulate matter. Increasingly, regulators are turning their attention to fine dust emissions from brake wear. On average, 31% of passenger- vehicle-related emissions are caused by brake wear. This results in more than 90 000 metric tons of fine dust per year in the OECD countries alone. The DiscCover solutions from Oerlikon Balzers and Oerlikon Metco significantly reduce fine dust from brake discs so that our customers are equipped to comply with stricter regulations as they improve their environmental footprint. and elsewhere [1] > We can help brake system manufacturers and designers prepare for stricter regulations by significantly reducing fine dust and extending disk life Reducing fine dust is great, but (1) this seems to only be about brake discs, not brake pads, and (2) there's no support in Oerlikon marketing materials for GP's claim that this magically means brake pads don't need replacing. > Oerlikon of Switzerland has brake pad technology that has near zero emissions and does not need replacing This seems not unlike the stories that go around about how someone was sold a 200mpg prototype car by accident but then the car company took it back because they don't want people to have them.
