A comparison of real driving emissions from Euro 6 diesel passenger cars with zero emission vehicles and their impact on urban air quality compliance – Urban air quality study: extension I

Report no. 8/18: This report describes an extension to the Urban Air Quality Study commissioned by Concawe that explored how urban air quality is affected by emissions from road transport and domestic combustion. In the first report a particular focus was placed on the impact of real driving emissions (RDE) on urban concentrations of nitrogen dioxide (NO₂) and particulate matter (PM10 and PM2.5) and the effect this may have on compliance with ambient air quality limit values at European, national and regional level.

The aim of this extension study is to determine how measured emissions from newer RDE compliant Euro 6 diesel passenger cars would affect the concentration of NO₂ in European urban environments. A comparison has also been made where the substitution of Euro 6d diesel passenger cars with zero exhaust emission equivalents is explored.
