49. GRPE adopted ECE/TRANS/WP.29/GRPE/2019/12 as amended by GRPE-79-21-Rev.1 as reflected in Addendum 1 to this report as draft Amendment 4 to UN GTR No. 2. GRPE also adopted the technical report (GRPE-79-22) as reproduced in Annex VI of the session report. GRPE requested the secretariat to submit Addendum 1 and Annex VI to WP.29 and AC.3 for consideration and vote at their November 2019 sessions.

120. Submitted for consideration and vote, the proposal for Amendment 4 to UN GTR No  2 on the measurement procedure for two wheeled motorcycles equipped with a positive or compression ignition engine with regard to the emissions of gaseous pollutants, CO2 emissions and fuel consumption (ECE/TRANS/WP.29/2019/121, ECE/TRANS/WP.29/2019/122 and ECE/TRANS/WP.29/AC.3/36), subject to the following modification in ECE/TRANS/WP.29/2019/121:

Paragraph 3.4.3.1 to Annex 1: “1.225 Pa” should read “1.225 kPa”.

121. The proposal was adopted on 13 November 2019 by consensus of vote of the following contracting parties present and voting: Australia, Canada, China, the European Union (representing Cyprus, Finland, France, Germany, Hungary, Italy, Lithuania, Luxembourg, the Netherlands, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom), India, Japan, Norway, the Republic of Korea, the Russian Federation, South Africa, Tunisia, Turkey and the United States of America.

122. The representatives from San Marino abstained from voting.

2. Mr. Rijnders, Chair of GRPE, opened the meeting and welcomed the participants. GRPE adopted the provisional agenda of the seventy-ninth session (ECE/TRANS/WP.29/GRPE/2019/9), as updated and consolidated in GRPE-79-09-Rev.3. GRPE took note of GRPE-79-01 on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

4. The secretariat introduced GRPE-79-02-Rev.1, announcing that the next GRPE session would take place on from 14 to 17 January 2020 and recalling the corresponding deadline (21 October 2019) for the submission of official documents. The Chairs and Secretaries of IWGs were invited to approach the secretariat to define the calendar of IWGs meetings for the January 2020 GRPE session. The secretariat also announced the potential shortage of meeting space capacity from October 2019 in the Palais des Nations.

5. The secretariat introduced GRPE-79-03 and reported on relevant items discussed during the 177th session of the World Forum for Harmonization of Vehicle Regulations (WP.29). He referred to ECE/TRANS/WP.29/1145 for further details.

6. The Chair presented GRPE-79-04-Rev.2 detailing priority topics for GRPE activities, as prepared by the Chair and the secretariat. The Chair highlighted the need to develop this GRPE priorities document to fulfil the political demand as stipulated in the Inland Transport Committee (ITC) Strategy adopted during the last ITC session in February 2019. WP.29 also expressed their wish to identify work priorities in the GRs to potentially allocate adequate resources to fulfil the objectives set by each GR. He also underlined that the priorities should be aligned with the SDGs, developed under the 2030 Agenda.

7. GRPE supported the proposal and found this approach highly relevant in the rapidly evolving context and digitalization of vehicles. Some Contracting Parties (CPs) wanted more clarity on the potential future topics under the UN vehicle agreements (1958, 1997 or 1998 Agreement) will be developed under. The secretariat highlighted this document is aimed at being a bottom-up from GRPE stakeholders that would then be discussed and coordinated during AC.2 sessions of WP.29.

10. GRPE edited GRPE-79-04-Rev.2 during the session and based on comments received from CPs not attending. GRPE agreed to submit the amended document to the next session of GRPE in January 2020 as an informal document (GRPE-80-04). The Chair proposed to present this document during the March 2020 session of WP.29 once GRPE had agreed on the content of the document.

13. The representative from CITA introduced GRPE-79-05 proposing amendments to the 06 and 07 series of amendments to UN Regulation No. 83. The representative from EC wondered if the proposed new paragraph 5.1.9. would not be more appropriate in UN Regulation No. 49 where there is evidence of Selective Catalytic Reduction (SCR) tampering of heavy-duty vehicle was better documented. The representative from CITA reckoned the issue with SCR tampering in heavy-duty applications was existing and documented and clarified the intention to amend UN Regulation No. 83 was to anticipate expected future issues for light-duty vehicles.

14. The representative from OICA stated the proposed amendment implied physical changes to existing vehicles for infrequent road worthiness tests. He added that such proposal does not make tampering more difficult. He said a better way would be to address the offer of tampering devices, for example following the initiative from Austria legally prohibiting the sale and advertisement of tampering devices. He did not support the proposal and encouraged closer collaboration with CITA to improve the situation of road-side and inspection tests. The representative from CITA agreed the proposal needed to be strengthened, and this proposal was a first step. He said that authorities performing road worthiness tests needed to be able to measure emissions to characterize tampering, which was not often the case today, partly because of lack of access to software and sensors signals of the vehicles.

15. The Chair highlighted undertaking the issue of tampering was an ample strategy needing diverse approaches to it, through vehicle design, PTI, roadside inspection, market availability, etc. and invited CITA to table a working document for the next session of GRPE in January 2020, in close collaboration with EC, OICA and other interested stakeholders.

11. The representative from CITA introduced GRPE-79-06 on the highlights of the CITA annual congress held in Republic of Korea in April 2019. He summarized the latest updates on emissions measurements during PTI tests. The Chair highlighted the importance of the topic and recalled it has been included in the draft priority list of GRPE (see para. 6).

12. The representative from Spain referred to the measurement of particulate number (PN) and asked whether a mature technology to measure PN during PTI tests was available on the market. The representative from CITA explained that the technology was mature and that some countries were about to implement PN measurements during PTI tests in the coming years, in the 2020/2021 time horizon. The representative from Netherlands confirmed PN tests are expected in 2021. He also highlighted the importance of in-use emission monitoring in the rapid technology changes the vehicle industry is facing, with digitalization, over-the-air updates and self-learning features that need to be considered.

37. The representative from the Russian Federation introduced GRPE-79-07 raising awareness of non-exhaust particulate emissions from brake, tyre and road abrasion. The Chair highlighted the topic was in the agenda of IWG on PMP, highlighting the relevance of the topic. He also mentioned GRBP was considering a proposal from Netherlands on road surface labelling that included traffic noise reduction, wet skid resistance, rolling resistance and lifespan (ECE/TRANS/WP.29/GRB/2019/2).

19. The Chair of IWG on WLTP introduced GRPE-79-08-Rev.1 updating GRPE on the latest activities of IWG on WLTP. He requested an extension until June 2020 for the activities of the group, as he recalled GRPE the current Terms of Reference (ToRs) of IWG on WLTP had an expiration date in December 2019. The representative from Canada asked about the plans of IWG on WLTP after Jun 2020. The Chair of IWG on WLTP stated the future will depend on the content of the work which remained to be defined at the time. The Chair of GRPE highlighted it would be important to hold the discussions with all other IWGs. GRPE noted the request for a meeting room for one and a half day during the GRPE week in January 2020.

20. The representative from EC indicated that the work item on road loads covered in the status report was discussed and some CPs requested it, but the item was finally not prioritized. She agreed with the extension of the ToRs for IWG on WLTP for six months and requested that longer-term work items should be considered in conjunction with the broader work priorities for GRPE (as introduced in paras. 6 to 10). The representative of Switzerland was also in agreement with the six-month prolongation and to further align with the GRPE priorities.

21. GRPE agreed to prolong the work of IWG on WLTP until June 2020, as reflected in Annex III.

2. Mr. Rijnders, Chair of GRPE, opened the meeting and welcomed the participants. GRPE adopted the provisional agenda of the seventy-ninth session (ECE/TRANS/WP.29/GRPE/2019/9), as updated and consolidated in GRPE-79-09-Rev.3. GRPE took note of GRPE-79-01 on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

16. The expert from OICA introduced GRPE-79-10 requiring clarification on the consolidation of ECE/TRANS/GRPE/2017/2 into UN Regulation No. 83. The representative from EC suggested that the issue identified could originate from how the document was drafted. The Chair accepted the request for clarification was valid and acknowledged the request for guidance from GRPE on consolidation interpretation when needed. The representative from the Russian Federation, as submitter of ECE/TRANS/GRPE/2017/2, confirmed that the new text is an addition to the existing paragraph, not a substitution. The Chair confirmed that paragraph 1.1. consolidated with Supplement 10 and 5 to the 06 and 07 series of amendments to UN Regulation No. 83 should read:

7. The expert from the Russian Federation presented ECE/TRANS/WP.29/GRPE/2017/2 on amendments to the scope of Regulation No. 83. He explained that the proposal was aimed at allowing extensions of type approvals granted under Regulation No. 83 to special purpose vehicles.

8. The experts from CLEPA and OICA expressed some concerns on the limitation of 2,610 kg reference mass introduced by the definition of special purpose vehicle in ECE/TRANS/WP.29/GRPE/2017/2. The expert from Hungary suggested the use of existing definitions in the Consolidated Resolution on the Construction of Vehicles (R.E.3). Following the discussion, the experts from Hungary and the Russian Federation presented GRPE-74-22 to amend ECE/TRANS/WP.29/GRPE/2017/2 by deleting the definitions of special purpose vehicle and armoured vehicle and referring to R.E.3 instead.

9. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/2 amended by GRPE-74-22 as reproduced in Annex IV and requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2017 sessions as draft Supplement 10 to the 06 series of amendments and draft Supplement 6 to the 07 series of amendments to Regulation No. 83.

17. The expert from OICA updated GRPE on the status of the work related to propose an amendment to UN Regulation No. 101 (GRPE-79-11) to accept the tests currently performed in the European Union in the interest of correlation between NEDC and WLTP outside of the European Union where such correlation does not exist. The representative of Australia described the measure taken in the country to accept approvals based on WLTP and still rely on NEDC-based values for fiscal and labelling purposes.

11. The expert from OICA introduced GRPE-78-20 proposing to amend UN Regulation No.101 to permit the measurement of fuel and energy consumption and CO2 emissions using road loads which are calculated according to the method used in EU correlation. The representative from EC sought clarifications on the use of CO2MPAS for this proposal. The representative from OICA explained that CO2MPAS formula are expected to be used for the calculation of road load coefficients, without using the CO2MPAS software itself. The representative from EC backed the proposal and requested that the EU JRC be involved in developing the working document. The Chair thanked the representative from OICA for initiating this effort and for making the latest legislative provisions available to all Contracting Parties.

28. The expert from OICA introduced GRPE-79-12 detailing the next steps to initiate work on the harmonization of fuel economy procedures for heavy duty vehicles. He emphasized that the workshop in January 2020 during the week of the next session of GRPE will be held for information sharing and to identify potential parties that would be interested to work on the topic.

29. GRPE noted the request for a meeting room for a half a day during the GRPE week in January 2020.

38. The Chair of IWG on Particle Measurement Programme (PMP) presented a status report on activities on exhaust and non-exhaust particle emissions (GRPE-79-13).

39. The representative from India enquired about any correlation between existing evaporation tubes and strippers for sub-23 nm particulate emission measurements. The Chair of IWG on PMP answered evaporation was working for diesel engines, and that for spark ignition engines (e.g. 2-stroke L-category vehicles), some artefacts were measured. IWG on PMP was considering adoption of two approaches for the future. The representative from India asked further explanations about the dispersion found in the round robin tests. The Chair of IWG on PMP explained two Condensation Particle Counters (CPCs) were connected to the same exhaust line, one to measure 23nm particulates, one to measure 10nm particulates. He highlighted the location of the sampling points are of high importance and could explain part of the dispersion found. He emphasized that the hot start variability was higher as absolute values were lower than for cold starts. The representative from India finally asked whether the dispersion was fit for post Euro 6 measurements. The Chair of IWG on PMP answered that only one CPC would be prescribed in the future legislation, ensuring more consistent measurement and easier location of the sampling point in the exhaust line.

40. The Chair requested about the expected timeline to deliver on a procedure for sub-23 nm particulate measurement. The Chair of IWG on PMP confirmed they are expecting a working document for the GRPE session of June 2020.

41. The representative of the United States of America confirmed the findings on non-exhaust particulate in the US were consistent with IWG on PMP and the results shown by the representative of the Russian Federation in GRPE-79-07. He explained that the characteristics of tyres are changing to improve safety and rolling resistance and encouraged GRPE to carefully consider the impact of such tyre modifications on the wear of tyres and associated particulate emissions. He proposed to potentially make a presentation at the next GRPE session in January 2020 about the on-going activities in the United States of America on the matter.

42. The Chair of IWG on PMP introduced the revised ToRs of IWG on PMP (GRPE-79-14) seeking to extend the activities of IWG on PMP until June 2021. The Chair of IWG on WLTP asked whether IWG on WLTP should anticipate some work loads to adapt UN GTR No. 15 to sub-23nm requirements. The Chair of IWG on PMP did not expect in-depth modifications to UN GTR No.15 and would be happy to further work with IWG on WLTP to better coordinate the activities.

43. The representative from OICA requested further considerations on transitional provisions when the new method to measure sub-23nm particulates had been finalized. The Chair agreed such considerations were important and will be undertaken when the new procedure became available and ready to be included into legal texts.

18. The expert from OICA introduced GRPE-79-15, GRPE-79-16 and GRPE-79-17 proposing modifications to the 07 series of amendments to UN Regulation No. 83 on On-Board Diagnosis (OBD). The representative from Netherlands, France and EC required more time to analyse the proposals and to consult internally with the appropriate experts on OBD. The representative from EC requested a more thorough assessment and more detailed specifications of the needs and requirements to amend the regulatory text. The Chair acknowledged that the specific expertise on OBD from CPs was in most cases not present in the room and proposed OICA to further develop the proposals and submit as working documents for the next session of GRPE in January 2020.

65. GRPE acknowledged the progress made by IWG on VIAQ and noted the request for a meeting room for half a day during the GRPE week in January 2020.

22. The representative from EC introduced GRPE-79-19 on the latest activities of the Transposition Task Force aimed at drafting a UN Regulation from UN GTRs Nos. 15 and 19. The representative from OICA requested about the possibility to include specific provisions for CPs only needing national application for a national context to not have to wait for the most stringent Level 1 subject to mutual recognition to enter into force to fully benefit from the latest evolution of the legal text. Currently an additional six-month period is envisaged so that the regional levels are not subject to mutual recognition. The representative from OICA also appealed to certification or Type Approval Authorities whether the proposed approach to identify the stringency level by its series of amendment number was enough to identify the harmonization level or that an indication of the level of harmonization would also be needed in the approval number.

24. The representative from EC introduced GRPE-79-20-Rev.1 detailing the latest activities from IWG on RDE. She added that, in parallel with the development of the UN GTR on RDE, a new UN Regulation on RDE would be developed, based on European Union legislation. GRPE agreed to the development of a new UN Regulation on RDE. The representative from European Union confirmed that both UN GTR and UN Regulation will be closely looked after to avoid any discrepancies between the two texts.

25. GRPE noted the request for a meeting room for a day during the GRPE week in January 2020.

70. The Chair highlighted that fuel quality was of paramount importance to deliver on sustained low emissions from cars, as both cleaner fuels and advanced emission control systems were needed to deliver on cleaner tailpipe emissions. Using the right fuel quality represented an essential prerequisite to a successful and long-lasting improvement of air quality.

71. He suggested that it would be important to include all vehicle categories in this document to provide a more comprehensive guidance to countries on the compatibility of vehicles emissions control systems and fuel quality requirements. The representative from IMMA supported the proposal from OICA, AECC and CLEPA and recognized fuel quality was an important topic. IMMA would consider covering the issue once the transposition of UN GTR No. 2 into a UN Regulation would be completed.
