From 1 June 2012, Hong Kong will apply Euro V diesel emissions standards to newly registered vehicles. The ruling, part of the Air Pollution Control Regulation 2012, will apply to heavy-duty vehicles over 3.5 tonnes. Those vehicles already registered will have to meet the standards from 31 December 2012.
Previously, Hong Kong had applied Euro IV standards since January 2006. Heavy-duty Euro V vehicles with diesel engines emit about 40% less Nitrogen Oxide (NOx) than those produced to Euro IV standards.
Euro V regulations permit a maximum emission of 2 grams per kilowatt-hour of NOx. AdBlue is an essential part of reducing NOx emissions where SCR technology is used.
Announcing this legislation development on Wednesday 29th May, a spokesman for Hong Kong’s Environmental Protection Department also said that it is Government policy to introduce the most stringent diesel emissions standards as soon as it is practical to do so.
Hong Kong’s progression to Euro V stands in sharp contrast to mainland China, which has delayedimplementation of China IV (equivalent to Euro IV) until July 2013.
