ICCT: Real world driving emissions

Real-world NOx emissions from new diesel cars could still exceed the Euro 6 emission limit of 80 mg/km by a factor of three or more, even after the new RDE regulation takes effect, according to research released today by the International Council on Clean Transportation.

But taking specific actions beyond those mandated in the regulation, such as introducing spot checks for randomly selected vehicles and expanding the range of driving conditions covered by RDE testing, could reduce new diesel car NOx emissions to 96 mg/km—just 1.2 times the Euro 6 limit—by 2022. These findings come while the European Commission and EU member states discuss further development of the RDE regulation.
