Publication of the Final report of the Study “Preparation of the legal and technical background for a voluntary EU standard for low emitting combustion engine driven cars (EULES)”

May 23, 2016

The final report of the EULES project, related to preparing the legal and technical background for proposing a future voluntary EU low emission limit for combustion engine driven cars, has been published by the European Commission and is ready for download.

The principal objectives of the project were to provide the background on the potential of a voluntary low emission standard for passenger cars, in order to deliver real-world emission levels below the most stringent current emission limits, as well as to develop the technical and legal background for its implementation. The EULES scheme provides the following:

  • - Guidance for environmentally conscious customers towards the purchase of vehicles with ‘clean’ emission profiles (low real-world driving emissions).
  • - a benchmark for local or national authorities when developing financial incentives or access and demand policies or establish green procurement rules, to promote clean transportation.
  • - incentive for manufacturers to produce vehicles that deliver significant and true on-road emission reductions over prior emission control concepts.

The project could successfully derive at major achievements, among which is the verification and experimental demonstration of the potential of diesel engine and after-treatment technology to reach real-drive emissions (RDE) levels which are below the Euro 6 emission limit, using today’s commercial available technology. The study demonstrates that emission levels corresponding to a conformity factor of as low as 0.5 is technically possible using today’s commercial technology. It further provides suggestions and options for the technical model and the legal approach that should be followed for a successful introduction of this voluntary scheme, as well as an assessment of the likely public response (customer acceptance) and the role of public authorities on how to support and promote the scheme with incentives, benefits, etc.
