Update from RDE IWG GRPE January 2019 From the sponsors: European Union Japan Korea

Background During last GRPE meeting, EU, Japan and Korea requested the creation of an RDE IWG The GRPE accepted the proposal during its June 2018 meeting Creation of RDE IWG accepted by AC.3 in its June 2018 meeting The relevant portions from the minutes are reported in the following slides

147.          The representative of the European Union … requests authorization to develop a new UN GTR on Global RDE. She highlighted the importance of this request, both technically and politically, with emissions control strategies now being globally developed by vehicle manufacturers. 148.          The timeline to develop the new UN GTR on Global RDE is ambitious due to the urgency to tackle the topic in a harmonized, coordinated approach. The process will be opened to all contracting parties interested in developing or improving their own national regulatory procedures. 149.          The representatives of Japan and the Republic of Korea supported the document and expressed the wish to participate in the IWG on Global RDE. 150.          The representative of the United States of America expressed his support for GRPE to begin exploring a harmonized test procedure on RDE, as soon as possible, through the work of an IWG on Global RDE.

151.          He expressed his support of a data-driven approach that would be inclusive of input from all the contracting parties, and that it would not be pre-determined that the European RDE is the only approach which should be considered. 152.          The representative of the United States of America expressed his belief that more time will be needed to be able to consider all inputs from all contracting parties. 153.          The representative of the United States of America stated that this work could lead to a UN GTR, though he did not believe that it was necessary at this time to make this decision. He added that an IWG should be formed to explore the development of a harmonized RDE methodology and at a future meeting of WP.29/AC.3 it could be decided, based on a more inclusive input from the contracting parties, if a UN GTR under the 1998 Agreement  would be the appropriate approach.

154. The representative of the United States of America stated that if AC.3 decides to move forward with the development of a UN GTR on Global RDE, the United States of America would participate in the early stages of the development. However, if the process was not data-driven nor inclusive of input from all contracting parties to the 1998 Agreement, the United States of America would consider exercising the right as a contracting party to make clear that it would not support the eventual adoption of a UN GTR for this new methodology. 155. AC.3 took into consideration the comments of the representative of the United States of America and granted authorization to develop a UN GTR on Global RDE. The request for authorization to develop a new UN GTR on Global RDE is reproduced in annex V of this report.

156. The Chair of GRPE congratulated all the parties who showed interest in participating in the development strengthened so as to ensure the adequate operation of state-of-the-art emission control systems in normal conditions of use. 157. He emphasized that the development of a harmonized real driving emissions test procedure would centralize expertise and resources for improved emissions measurement. This would also support significant economies of scale across the automotive sector.

Meetings The group met already on: 11-12 September 2018 in Brussels 27-28 November 2018 in Brussels 9 January 2019 in Geneva And planned next meeting for 1-2 April 2019 in Japan

Confirmed Roles: Chair: European Union (P. Dilara) Vice-chairs: Japan (Y. Kono) and Korea (J. Park) Secretaries: OICA (P. Mendoza-Villafuerte), JASIC (N. Ichikawa)

1st Meeting Presentation of development of the RDE methodology in Europe Presentation of Japanese methodology Presentation and discussion of the joined text of the two methodologies, based on the RDE4 version Discussion on ToR Work is needed in order to understand how other CPs driving and boundary conditions can be taken into account

2nd Meeting Presentation of Indian RDE methodology Presentation of the scope of the US work for RDE development Continuation of the discussion on a consolidated text Presentation by JRC of changes made in the RDE4 act Presentation of the OICA position

3rd Meeting Presentation of Korean RDE methodology Presentation by JRC of testing guidelines and of RDE data and tool available by JRC Discussion on creation of a common RDE database with data relevant for the further development of RDE GTR Discussion on ToR, tasks and timeline

Work on the RDE GTR GTR should contain only technical procedures The group is considering how to adapt the procedures in order for them to work in various regions Extra testing may be required The issue of how to deal with the uncertainty of measurements is still open CEN is developing a standard on the performance of PEMS In case this is not ready in time, we will need to take this up in the GTR

Detailed task list-1 Driving and emission data collection: 1 June 2019 Evaluation of Temperature and Altitude boundaries using regional needs: first delivery by 1 April 2019 meeting in Tokyo Evaluation of cumulative altitude gain: 1 April 2019 Introduction of certification lab cycles other than WLTP (FTP, MIDC,…): first delivery on 1 October 2019, final delivery end 2019* *in case the work cannot be performed in time for having a draft text by end of 2019, maybe to be postponed for second phase.

Detailed task list-2 Evaluation of trip composition: first delivery April meeting, final for June 2019 Annex on uncertainty of measurements: October 2019 Evaluation of trip severity/trip dynamics: First delivery for June 2019 Evaluation of emissions corrections and moderate/extended conditions: October 2019 Drafting of GTR: already started, informal for January 2020 GRPE
