The European Union published a new regulation containing the next level of emissions requirements for heavy-duty vehicles, known as Euro VI. The regulation was published July 18, according to InterRegs, an online resource for global vehicle safety and emissions regulations. Identified as (EC) No 595/2009, the regulation will apply to all passenger vehicles and goods vehicles with a “reference mass” exceeding 2610 kg. InterRegs says this equates to a curb weight of approximately 2510 kg. The new limits represent an 80% reduction in nitrogen oxides (from 2.0 g/kW·h to 0.4 g/kW·h) and a 66% reduction in particulate matter (from 0.03 g/kW·h to 0.01 g/kW·h) compared to Euro V requirements. Compliance becomes mandatory from Dec. 31, 2012, for new types of vehicles and from Dec. 31, 2013, for all new vehicles.
