Findings from the Driver and Vehicle Standards Agency (DVSA)’s 2018 Vehicle Emissions Testing Programme highlight the threat to air quality improvements in ultra-low emission zones (ULEZs) caused by emissions from some Euro 6 vehicles.
Tests carried out by the DVSA on a range of popular Euro 6 vehicles identified low and high emitters in line with the results of similar tests conducted for Allow Independent Road-testing (AIR) and published in the AIR Index. The DVSA tests reveal that some vehicles meeting the legislated laboratory tests produce up to 20 times the NOx emissions limit during the WLTP track test.
Consequently, city policy makers across Europe who are using, or plan to use, Euro 6 as the basis for city access will be unable to stop over-emitting cars adding to poor urban air quality. AIR has said that it’s not aware of a Clean Air Zone or ULEZ operating in Europe which has implemented a way to discriminate between clean and over-emitting Euro 6 vehicles.
AIR is calling on policy makers in London and across Europe to make clean air zones more effective by tackling the issue of dirty Euro 6s, using ratings such as the AIR Index, to bring air quality into legal compliance as soon as possible.
