Expert studies shows that under real driving conditions latest technology diesel cars are compliant with EU emission limits for NOx and PM
Two studies conducted by Ricardo and by AERIS conclude that EURO 6d (temp) diesel cars tested under « RDE conditions » are compliant with the EU emissions limits for NOx and PM. Replacing all new diesel cars by zero emission vehicles (ZEV) will offer little improvement to the compliance outlook with ambient air quality limit values compared with the EURO 6d scenario. The AERIS study furthermore shows that there is almost no difference in the level of population exposure between a ZEV scenario and the progressive replacement of diesel cars by Euro 6d diesel cars. Finally, understanding emissions sources at the local level is key to finding the targeted measures that will be the most effective and best value for cities for addressing remaining exceedances and hot spots.
