Real driving emissions of Euro6 diesel passenger cars and their impact on urban air quality

Concawe commissioned two studies in 2017 to determine the expected emissions from the latest Euro6 diesel passenger cars (including Euro 6d certified since September 2017) under the new testing methodology and to understand how the emissions from these new diesel cars would impact ambient air quality compliance when compared with zero emission vehicles (ZEV).

The first study, completed by Ricardo, summarized RDE emission test data for Euro 6 passenger cars. The second project, completed by AERIS Europe, incorporated the data from the Ricardo study and modelled the impact of the diesel passenger cars on NO2 and PM compliance, and population exposure under different scenarios including a scenario where all new passenger cars are replaced with zero tailpipe emission vehicles. A summary of both studies is provided in the following sections.
