Legal obligations relating to emission measurements in the EU automotive sector

© Alterfalter -

Vienna, 21 June 2016 - On behalf of the European Parliament the Umweltbundesamt (Environment Agency Austria, EAA) conducted a study to analyse the discrepancy in NOx emissions between type-approval tests and real-world driving. It examines the legal stakeholder obligations with regard to emission measurements in the European type-approval process and offers insights into the practical implementation of type-approval procedures throughout the EU. The study also gives recommendations for the improvement of the legislation and the type-approval process:


Especially the streamlining of the highly complex existing legislation and regulations in order to clarify responsibilities and tasks of MS, typeapproval authorities, manufacturers and technical services will be necessary to harmonize standards and overcome conflicts of interests.

Concerning the switching from the NEDC to the WLTP test cycle from 2017 onwards, the study comes to the conclusion that specification and adequate definitions of the boundary conditions in the emission test that represent real-world driving conditions in the EU will be crucial. In addition transparency of test results and test settings as well as independency of bodies and test laboratories that are re-testing are recommended.


Furthermore clear sanctions on manufacturers that fail to comply with emission legislation at EU level will lead to an optimisation of exhaust gas systems on the basis of real driving conditions.
