Exhaust Emissions Testing

Cymraeg

Before passenger cars can be type approved for sale in the European Union they must meet certain standards for exhaust emissions. The more stringent Euro 4 limits specified in Directive 98/69, were introduced on 1st January 2005 and became fully effective on 1st January 2007. In late June 2007, European Regulation EC/715/2007 introduced Euro 5 and Euro 6 limits. New model types may now be approved to the Euro 5  standard and this will be compulsory for all new cars from 1st January 2011.  As with the fuel consumption tests a single vehicle representative of a particular version is tested.

Because of the nature of testing procedures the type approval emission figures listed in the tables should be treated with caution and specifically should not be used to rank a number of vehicles for which similar figures are quoted.
