Environmental and Propulsion Performance Requirements for L-category Vehicles (EPPR)

This page provides access to the documents and meetings of the L-Vehicle Environmental and Propulsion Performance Requirements.
The next EPPR session will be held on
15 Apr 2020.

The informal working group on environmental and propulsion performance requirements for L-category vehicles aligns with an initiative by the European Commission to revise type approval procedures for such vehicle types (see Regulation (EU) No 168/2013).

L-category vehicle is the family name of light vehicles such as powered cycles, mopeds, motorcycles, tricycles and quadricycles used in UN type-approval regulations. Category 3 is the counterpart class used by Global Technical Regulations.

In order to promote harmonization, the European Commission is pursuing the development of new laws under the proposed EU type-approval system for L-category vehicles through this informal group.

The EPPR group is developing new provisions concerning the following environmental performance assessment test:

  • I Tailpipe emissions test after cold start;
  • II Tailpipe emissions test at (increased) idle / free acceleration test;
  • III Emission test of crankcase gasses;
  • IV Evaporative emissions test;
  • V Durability testing of pollution control devices;
  • VII Measurement of energy efficiency (CO2 emissions, fuel consumption, electric energy consumption and electric range determination);
  • VIII environmental on-board diagnostic verification tests as well as functional on-board diagnostics.
  • Test VI: Cold ambient emissions is considered outside the scope of this effort.

Revisions to GTR No. 2 (WMTC) will address test types I, II, and VII while new Global Technical Regulations are expected on “crankcase and evaporative emissions” (IV and III, respectively), OBD (VIII), and, in a second phase, on durability and “propulsion unit performance requirements”.

The initial completion date for the first phase of work was June 2016; however, a proposal is under consideration to extend the EPPR group mandate into 2020.


The EPPR informal group has set up a page for its OBD 2 Correspondence Group with documents covering the motorcycle on-board diagnostics work.
