Abstract
-
Post-Euro-6 emissions regulation in Europe is an opportunity to simplify and refocus on emerging environment threats.
-
Certain unregulated tailpipe pollutants, such as ammonia, which contributes to secondary particle formation, are candidates for future regulation.
-
Volatile organic compounds are of interest from several angles: vehicle interior air quality and the off-gassing from materials; tailpipe speciation of hydrocarbons including formaldehyde; and off-gassing from tyres.
-
Tyre wear emissions are currently unregulated but are believed to be a growing contributor to air and marine pollution.
-
Emissions Analytics runs independent test programmes that investigate and quantify real-world exhaust, cabin and tyre pollution. Resulting measurements form the EQUA Index database, which is the source of results presented in this paper.
