European Emission Regulations

As environmental policies continue to evolve, several efforts have been made to improve the air quality by limiting pollution from all sources.

European emission regulations for light duty vehicles were formerly specified in Directive 70/220/EEC.  This Directive was repealed and replaced by regulation 715/2007 (EURO 5/6).
