CLEPA Statement | Real Driving Emissions – timing considerations

CLEPA is committed to the effective reduction of automotive emissions, also in real-world driving.

in CLEPA, 18-05-2015

Diesel and gasoline technologies are available to achieve this objective. CLEPA believes that the modern combustion engine is part of the solution for both CO2 reductions and air quality improvements. We therefore support the introduction of a real-driving emissions (RDE) test to complement current testing.

The details of the full package of requirements need to be defined as soon as possible (by latest Q2/2015 for introduction by September 2017). A monitoring phase must immediately follow together with a full access to the collected data. Those data from monitoring will bring real-life test experiences and initial emission figures with RDE-test in order to identify any unknown issues. The monitoring phase should also be used to evaluate the defined boundary conditions and study the normalisation tools carefully. In this respect, CLEPA supports the notion of technology-neutrality.

As regards the timing for the mandatory introduction of the RDE-test, CLEPA supports September 2017 for new light-duty types. The date for all new vehicles needs careful consideration of the significant application effort for both diesel and gasoline vehicles that will be required, especially as ongoing production will be affected. CLEPA members feel that therefore reasons exist for an ambitious but practical introduction scenario avoiding an unrealistic type approval situation. For all new vehicles, CLEPA supports a reasonable transition period following the RDE introduction for new types. In particular, for models coming to the end of production in 2019, we encourage further discussions on an appropriate solution.


CLEPA is the European Association of Automotive Suppliers.

111 of the world’s most prominent suppliers for car parts, systems and modules and 24 National trade associations and European sector associations are members of CLEPA, representing more than 3 thousand companies, employing more than 5 million people and covering all products and services within the automotive supply chain. Based in Brussels, Belgium, CLEPA is recognized as the natural discussion partner by the European Institutions, United Nations and fellow associations (ACEA, JAMA, MEMA, etc).

Facts about the European automotive industry
