Proposal from the informal working group on Periodical Technical Inspections to replace “visual” by “visible” with regard to the observation of excessive smoke emissions.

121. The World Forum approved the two documents amending Resolution R.E.6 on requirements for testing equipment, for skills and training of inspectors and for supervision of test centres.

Working draft informal document for presentation to the 82nd (January 2021) GRPE session.

GRPE proposal for a new UN Regulation on uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to real driving emissions (RDE).

Note: GRPE withdrew its request for a vote to adopt the proposal for the new UN Regulation on RDE due to on-going discussions concerning the conformity factor.

121. The World Forum approved the two documents amending Resolution R.E.6 on requirements for testing equipment, for skills and training of inspectors and for supervision of test centres.

62. The Chair introduced GRPE-81-06 as the revised GRPE priority list following the latest guidelines received by the Administrative Committee for the Coordination of Work (WP.29/AC.2). The representative from the EC introduced GRPE-81-34 on proposed amendments to GRPE-81-06 which deleted the timeline indication for tyre wear emissions. The representative from the UK underlined that in some countries including his, tyre emissions were a high priority. The representative from the EC explained that in her view, there was not enough knowledge nor literature on the issue yet to develop regulatory material. Furthermore, she noted very few activities were expected in the near future that could feed the development of a robust test procedure. The Representative from the UK argued that priorities did not necessarily mean on-going or forthcoming activities, and that resources could be allocated based on priorities to fast track the development of knowledge for regulatory purposes.

63. The representative from OICA sought clarification on sub-23 nm PN measurements and its scope. The Chair of the IWG on PMP underlined that Sub-23 nm PN measurement was aimed for both light- and heavy-duty applications, in the laboratory and on-road. He added that the proposed Amendment 6 to UN GTR No. 15 endorsed by GRPE (para. 12-13) only covered the laboratory part for light-duty vehicles, and that on-road applications for both light and duty vehicles, and heavy-duty lab test were still to be developed.

64. The representative from Australia also emphasized that transposition of the latest European regulation on Heavy Duty (Euro VI Step E) into UN Regulation No. 49 should be prioritized.

65. GRPE agreed to such proposals and amended GRPE-81-06 into GRPE-81-06-Rev.1 during the session, and requested the secretariat to send GRPE-81-06-Rev.1 to WP.29 secretariat for further consideration by WP.29/AC.2.

This document is a first draft to restructure the most recent version of the RDE GTR (“20200216_GTR_RDE_draft_9b_JRC.docx”) to align, where appropriate, with the structure developed for UNR RDE (GRPE/2020/15 as amended by GRPE-81-16). The document also identifies where the requirements/provisions in the GTR were updated for the UNR – for decision as to whether the UNR provisions should be incorporated into the GTR.

17. The Chair of the IWG on RDE introduced the status report of the IWG (GRPE-81-17); mainly focusing on the development of the draft new UN Regulation on RDE submitted to GRPE as ECE/TRANS/WP.29/GRPE/2020/15 as amended by GRPE-81-16. She also introduced GRPE-81-26 complementing the draft text of the UN Regulation with a template of the data report file that shall be used to gather the data collected during the test and to check some of the trip validity conditions, specifically designed for the RDE tests contained in the draft new UN Regulation. She finally informed GRPE that some elements remained in square brackets as there are still regulatory work going-on at the European which might have an impact on the text proposed and might lead to a postponement to later session of WP.29 if the EU regulatory process is not finalized by then. GRPE noted those considerations.

18. The representative from OICA sought further clarifications on the update to UN Regulation No. 83 needed as a consequence of the new UN Regulations on WLTP and RDE. The expert from the EC stated there was a need to further evaluate the changes for UN Regulation No. 83 also taking the EU legal framework into account. She clarified such assessment was expected to be finalized before the next GRPE session in January 2021, especially with respect to in-service conformity provisions. The representative from Japan agreed the inclusion of in-service conformity into UN Regulation No.83 should be looked after carefully as it could also be part of WLTP provisions.

19. The Chair congratulated the IWG on RDE for the achievements in such limited time frame, getting consensus so that the draft UN regulation reaches full harmonization.

20. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/15 and GRPE-81-16 as amended by Addendum 2 to this chair’s notes and complimented by GRPE-81-26 that will be uploaded on the UN Regulation webpage once it is available. GRPE requested the secretariat to submit Addendum 2 to WP.29 and AC.1 for consideration and vote at their November 2020 sessions as draft new UN Regulation No. [XXX] on RDE. The representative of the EC informed some elements were left in square brackets waiting for the outcome of local discussions in the region. She indicated that the square bracket would be removed prior to the adoption by WP.29/AC.1.

21. She finally updated GRPE on the latest development and forthcoming plans for the development of a draft new UN GTR on RDE still being discussed with a larger group of stakeholders involved.

22. GRPE noted the request for a meeting room for half a day during the GRPE week in January 2021.

Web conference held on 11 May 2020.

22. GRPE noted the request for a meeting room for half a day during the GRPE week in January 2021.

Appendices concerning “assessment of overall trip dynamic using the moving averaging window method”, “calculation of the final RDE emissions results”, and “assessment of excess or absence of trip dynamics”.

70. The Chair introduced GRPE-80-04-Rev.1 as the GRPE list of emission topics that GRPE would regularly discuss and may decide to work on if and when resources are available. He reminded this list did not constitute a declaration of intent that the topics included would be tackled by GRPE in the future. He also recalled that keeping such a list open and regularly updated would allow GRPE to be more reactive when new issues arose and ready to cover new topics when pertinent. He reiterated GRPE-80-04-Rev.1 was to remain an GRPE internal document for its own use and information.

71. The representative from OICA requested more information about brake wear emissions topics and how to tackle this topic and by which GR. He also asked whether a more extensive definition of geofencing was available. The representative from EC thought brake emissions would preferably be considered at a vehicle scale and would preferably be considered in GRPE. The Chair emphasized that there would be close cooperation with other GRs working on brake issues, and confirmed GRPE was the appropriate GR to develop the new provisions on brake wear emissions.

72. The representative from India requested more clarity about the destination of the potential items, whether UN Regulation or UN GTR. The Chair clarified that the emission topic list was a starting point and its aim was not to contain any prescription on to which agreement each topic would go.

73. The representative from Spain asked whether the inclusion of life cycle analysis was referring to all vehicle and energy types. The Chair replied that life cycle analysis was still a nascent activity where legislative pathway still had to be defined. New energy types for vehicles needed to have a broad coverage, and he felt GRPE was not in a position to work on this yet.

74. The Chair introduced GRPE-80-05-Rev.2 as the draft list of priority for GRPE that WP.29/AC.2 requested each GR to send so that the coordination of tasks could be better overseen by WP.29/AC.2.

75. The representative from the Netherlands thanked the Chair for putting together this list and insisted that cars were more and more becoming computers on wheels and that vehicles would therefore evolve over their lifetime through software updates for example and that the issue of lifetime compliance was of high importance in his view.

76. The representative from the United Kingdom of Great Britain and Northern Ireland insisted tyre wear particulates and heavy duty hybrids were two areas of particular concern for his country and was happy to see those topics reflected in the list.

77. GRPE adopted GRPE-80-05-Rev.2 as amended during the session (GRPE-80-05-Rev.3) and requested the Chair and secretariat to send it to WP.29 secretariat for further consideration by WP.29/AC.2.

70. The Chair introduced GRPE-80-04-Rev.1 as the GRPE list of emission topics that GRPE would regularly discuss and may decide to work on if and when resources are available.

69. The Chair introduced GRPE-83-35 as revised list of priorities to be shared with WP.29. The representative from the EC called for prior consultation within GRPE before including new element in the priority list.

70. The representative from Japan stated that carbon neutrality was now a crucial issue in the country and required the issue of life cycle analysis to be considered by GRPE as candidate to be included in the priority list, as was already the case in the GRPE emission items list (GRPE-80-04-Rev.1). the Chair agreed to consider this at the next session of GRPE in November 2021.

GRPE to consider the draft developed text of UN GTR on Real Driving Emissions by the RDE IWG

30. The representative from EC introduced GRPE-80-29 detailing the latest activities from IWG on RDE. She invited all stakeholders to consult GRPE-80-30 and GRPE-80-31 and to comment the draft UN GTR and UN Regulation on RDE. The representative from India requested more details on the timeline for the UN GTR and UN Regulation. The representative from EC commented that both UN GTR and UN Regulation are expected to be proposed simultaneously at the next session of GRPE in June 2020. The representative from Australia requested clarifications about the arrangements for obtaining an approval under the proposed UN Regulation, that contained one test with two methods. He asked if both methods would need to be passed successfully to get an approval. The representative from EC answered that indeed both methods would need to be passed and was happy to have found a common denominator with all stakeholders involved for most of the provisions in the UN Regulation.

31. The secretariat noted that some elements in the draft UN GTR are left to contracting parties to decide. He asked whether those elements are expected to be harmonized and to be tackled in the phase 2 activities of the UN GTR development. The representative from EC clarified that such elements might be removed in the next phase of the UN GTR development to streamline the next amendment of the UN GTR. The representative from OICA expressed his appreciation to the level of harmonization achieved in such a tight time frame.

32. The Chair expressed his gratitude and appreciation to all the efforts made and reckoned the challenges to reach full harmonization given the complexity of the emission legislation files.

33. GRPE noted the request for a meeting room for half a day during the GRPE week in June 2020.

This draft regulation from the RDE IWG aims at providing a worldwide harmonised method to determine the levels of Real Driving Emissions (RDE) of gaseous compounds and particles from light-duty vehicles.
