EURO V

[risvan]

European emission standards define acceptable limits for exhaust emissions of new vehicles sold in EU member states. The emission standards defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards. Currently, emissions of Nitrogen oxides (NOx), Total hydrocarbon (THC), Non-methane hydrocarbons (NMHC), Carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, lorries, tractors and similar machinery, barges, but excluding seagoing ships and aero planes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardized test cycle. Non-compliant vehicles cannot be sold in the EU, but new standards do not apply to vehicles already on the roads. No use of specific technologies is mandated to meet the standards, though available technology considered when setting the standards. New models introduced must meet current or planned standards, but minor lifecycle model revisions may continue to offered with pre-compliant engines. In the early 2000s, Australia began harmonizing Australian Design Rule certification for new motor vehicle emissions with Euro categories. Euro II was introduced on 1 January 2006 and is progressively being introduced to align with European introduction dates.

EURO V is the most recent set in a series of mandatory European emission standards applying to new road vehicles sold in the EU. For heavy duty vehicles (lorries) the standards apply to vehicles brought on the market from October 2008. It requires Heavy Goods Vehicles (HGVs) to emit no more than 2.0 g/kWh of NOx and 0.02 g/kWh of PM. As yet, there is no Euro V standard applying for passenger cars, but a recent proposal suggests to limit diesel car emissions to 0.200 g/km of NOx and 0.005 g/km of Particulate Matter (PM), petrol cars to 0.060 g/km NOx and 0.005 g/km PM.

The standards do not mandate the application of specific technologies, but it is widely expected that diesel particulate filters will need to be fitted in diesel vehicles to comply with the PM standard.
