9. The Chair briefly introduced ECE/TRANS/WP.29/2020/92 and ECE/TRANS/WP.29/2020/93 that were submitted to the June 2020 session of WP.29 from EU and Japan as amendments to the new UN Regulation No. [154] on WLTP already adopted by GRPE during the January 2020 session. Both documents proposed changes to improve the text emerging from the development of Amendment 6 to UN GTR No. 15. GRPE noted the amendments and thanked the Informal Working Group (IWG) on WLTP and the Contracting Parties (CPs) involved in the preparation of these documents.

10. The representative from OICA introduced GRPE-81-30 and GRPE-81-35, amended by GRPE-81-29-Rev.1 during the session. These documents contained clarifications to UN Regulation No. [154] on WLTP. As requested during the last session of GRPE (ECE/TRANS/WP.29/GRPE/80, para. 15), these documents were aimed at providing guidance to future users of UN Regulation No. [154] on WLTP. The secretariat then introduced GRPE-81-36 presenting various options to provide visibility to such clarification / guidance documents. GRPE agreed to create a new section on the GRPE website, similar to those appearing in the GRE and GRBP sections, under " Documents for reference only", where GRPE-81-29-Rev.1 would be uploaded.

GRPE-81-29/Rev.1 | WLTP: Clarification of points regarding “UN Regulation WLTP“ UNR WLTP having features that have not been seen before in Regulations of the 1958 Agreement and GRPE therefore decided to commission this document to assist all users of this Regulation in their understanding. UNR WLTP will have 3 Levels. There are two regional Levels (contained within Level 1), and one harmonised Level (Level 2). The regional Levels reflect the current (at the time of adoption) emissions legislation in the EU (Level 1A) and in Japan (Level 1B). The harmonised level is the only level which will be accepted as part of an approval to Regulation 0 (International Whole Vehicle Type Approval – IWVTA)

12. The representative from EC, drafting coordinator for WLTP activities, introduced ECE/TRANS/WP.29/GRPE/2020/14, as amended by GRPE-81-14, as draft Amendment 6 to UN GTR No. 15, together with its technical report (GRPE-81-15). The Chair from the IWG on Particulate Measurement Protocol (PMP) also presented GRPE-81-10 introducing revisions also to be included in ECE/TRANS/WP.29/GRPE/2020/14 as part of Amendment 6 to UN GTR No. 15 on a supplementary methodology to measure sub-23nm particulates. The Chair of the IWG on PMP also introduced GRPE-81-11 providing explanatory note on the sub-23nm procedure part of Amendment 6 to UN GTR No. 15. He also informed GRPE that GRPE-81-11 had been included in the technical report of Amendment 6 to UN GTR No. 15 (GRPE-81-11 is included in GRPE-81-15).

13. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/14, GRPE-81-14 and GRPE-81-10 as amended by Addendum 1 to this chair’s notes. GRPE also adopted the technical report (GRPE-81-15) as reproduced in Annex V. GRPE requested the secretariat to submit Addendum 1 and Annex V to WP.29 and Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their November 2020 sessions as draft Amendment 6 to UN GTR No. 15.

GRPE-81-10 | GTR 15: Proposal to amend sub23 nm particle provisions of the draft Amendment 6 Proposal from the Particle Measurement Programme informal group to:<ul><li>Modify the existing solid PN measurement methodology having a 50% cut-off size at 23 nm (SPN23) in order to allow the use of catalyzed volatile particle remover (VPR) and introduce minor improvements, and</li><li>Include as a second option a solid PN measurement methodology with a 65% cut-off size at 10 nm (SPN10).</li></ul>

14. The Chair of the IWG on WLTP presented GRPE-81-20-Rev.1. highlighting the latest activities of the IWG. He concluded by stating that the IWG mandate was expiring in June 2020 and no Contracting Parties had the resources to become the main sponsor to carry on with the activities. He suggested WLTP-related activities that still require further work, if any, would be developed by interested parties on an ad-hoc basis and be submitted to GRPE for its consideration. The representatives from the EC, the United Kingdom of Great Britain and Northern Island (UK) and of the United States of America showed their support for such approach and confirmed their willingness to be involved to ad-hoc discussions should the need arise.

15. The Chair of GRPE thanked the IWG on WLTP for the tremendous achievements over the last 15 years and reckoned WLTP is an acronym well-known all over the world, not only by expert involved in WP.29 activities. He regretted a proper farewell to the WLTP family could not be done in person, and offered, if possible, to have a physical event during the next session of GRPE in January 2021. GRPE shared the congratulations to the IWG and praised the achievements of the group.

16. GRPE noted the request for a meeting room for half a day during the GRPE week in January 2021 for the ad-hoc group looking at WLTP-related issues.

3. (c) Worldwide harmonized Real Driving Emissions test procedure

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.

26. The expert from OICA informed GRPE that OICA wished to withdraw ECE/TRANS/WP.29/GRPE/2020/13 from consideration by GRPE. He detailed recent findings could allow the scope to be enlarged and the document therefore to be more comprehensive for the forthcoming sessions of GRPE. GRPE took note of OICA’s decision.

GRPE/2020/13 | UN R85: Proposal for a new Supplement Proposal to permit the use of the gaseous reference fuels described in UN R83 in order to reduce potential testing complexity.

27. The expert from Liquid Gas Europe introduced ECE/TRANS/WP.29/GRPE/2020/11, as amended by GRPE-81-37. The proposal was supported by the representative from Italy. The representative from the UK requested some clarifications around the notion of special provisions in the context of UN Regulation No. 115. The expert from Liquid Gas Europe agreed to add more clarity in forthcoming amendment proposals and to ease the processing in the case of specific vehicle technologies for Type Approval Authorities (TAAs).

28. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/11 and GRPE-81-37, as amended by Annex VI and requested the secretariat to submit Annex VI to WP.29 and AC.1 for consideration and vote at their November 2020 sessions as draft Supplement 9 to UN Regulation No. 115 (LPG and CNG retrofit systems).

29. The representative from CITA introduced GRPE-81-18 and GRPE-81-19 proposing the introducing of Particulate Number (PN) reference value tests in UN Regulations Nos. 24 and 83, that could be used, for example, as part of roadworthiness tests during the lifetime of the vehicle. The representative from CITA explained this first introduction to the documents was primarily aiming at gathering the interest of GRPE to work on such issue.

30. The representative from OICA regretted that both informal documents had been submitted soon before GRPE, and therefore limited time was available to carefully study the proposals. He highlighted GRPE-81-19 was not in line with GRPE-81-28 proposed by OICA (para. ‎32). He finally wondered if the proposals from OICA would have an impact on the cost of Periodic Technical Inspections (PTI).

31. The representative from EC deplored a premature proposal given the importance of the issue for assessing Diesel Particulate Filters (DPFs) deterioration. She stated the EC would be willing to redefine the test included in UN Regulations Nos. 24 and 83 to include PN. The representatives from NL, which is likely to include PN tests during PTI as of 2021, declared his willingness to work on a more refined proposal. The representative of Germany also supported the initiative and stated he would be happy to contribute.

32. The representative from OICA briefly introduced GRPE-81-28 proposing to remove UN Regulation No. 24 from the scope of UN Regulation No. 49. The representative from EC underlined such proposal was not on the table at this stage.

33. The Chair proposed GRPE to consider a full package during the next session of GRPE in January 2021 including the views of stakeholders having shown interest to work on the topic.

GRPE-81-18 | UN R24: Proposal for amendments to Supplement 5 to the 03 series of amendments Provisions to define a reference value for particle number

34. Given the circumstances and the limited time for the virtual meeting, GRPE did not consider this agenda item.

6. (b) UN Global Technical Regulation No. 11

35. Given the circumstances and the limited time for the virtual meeting, GRPE did not consider this agenda item.

7. Particle Measurement Programme (PMP)

36. The representative from the EC, chair of the IWG on PMP, introduced GRPE-81-31, presenting a status report of the activities of the IWG on PMP since the last session of GRPE. He highlighted the strong progress made by the IWG on both exhaust and non-exhaust emissions sources that, for example, led to the inclusion of sub-23 nm PN methodology in Amendment 6 to UN GTR No. 15 (para. ‎12). He also described the latest activities on non-exhaust particulate emissions and requested GRPE to host a one-day workshop on brake emission in conjunction with the next GRPE in January 2021.

37. The representatives from the UK and EC explained they would now like, as a next step, to include sub-23 PN requirements into UN GTR No. 4 on emissions from Heavy Duty Vehicles (HDV). The representative from EC also offered the possibility to host the workshop on brake emissions at the EC facilities in Geneva. The representative from OICA sought clarifications on the inclusion of sub-23 PN in UN GTR No. 4 and how differences between light duty vehicles and HDVs could be taken into account when designing a procedure for HDVs. The Chair of the IWG on PMP said initial thoughts would be to sample directly raw exhaust in the case of HDVs and stated no preferences with respect to the process of its inclusion in HDV legislation. The representative from EC added that how and when it would be included was still being discussed among interested parties.

GRPE-81-31 | PMP: IWG Status report

38. The expert from EC, Chair of the task forces on brake emissions introduced GRPE-81-12 on an interim report on the activities on brake emissions. He detailed the achievements reached so far, including the definition of the brake emissions test cycles taken from the WLTC database, as part of the activities of the task force 1. He highlighted the on-going work on defining a procedure (task force 2) to measure brake dust emissions had been slowed down because of the Co-VID19 crisis and the difficulty to perform lab and other types of physical tests.

39. The representative from the UK highlighted non-exhaust are becoming a priority for come CPs, and that for example, microplastics from tyre wear represented a significant share of microplastics in the environment. The expert from EC explained that tyre wear was indeed a topic of high interest and that a research project was expected to be initiated soon at the European level to look closely at this issue. GRPE congratulated the excellent feedback on the brake emissions activities and encouraged regular updates on progress of this item that is part of GRPE priority list (Chapter XIV).

GRPE-81-12 | Brake emissions protocol status update and proposal The first part of the PMP Brake Protocol for measuring brake particle emissions and addresses items using a new WLTP-Brake Cycle in conjunction with an inertia dynamometer test. The PMP Brake protocol will include three sections aiming to provide a comprehensive protocol for testing facilities:<ul><li>Inertia Dynamometer Protocol to Measure and Characterise Brake Emissions Using the WLTP-Brake Cycle;</li><li>Part 2: Minimum Requirements and Guidelines for Sampling and Measurement of Brake Emissions for Particle Number and Particle Mass;</li><li>Part 3: Reporting Test Results from Brake Emissions Testing.</li></ul>

40. The Chair of the IWG on PMP introduced GRPE-81-13 on a revision of the Terms of References (ToRs) of the IWG to include on-road test procedure definitions, which are expected to be developed for light- and heavy- duty application concerning the sub-23 nm PN emissions. GRPE agreed to revise the ToRs of the IWG on PMP as proposed in GRPE-81-13.

GRPE-81-13 | Proposal to amend the PMP informal group terms of reference Proposal to update the PMP mandate with a view to delivering the following results:<ul><li>Proposal for a new methodology for exhaust PN measurement with a d50 cut-off size reduced to 10 nm: June 2020</li><li>Proposal for HD raw exhaust PN sampling and extension of sub-23 nm procedure to HD engines: January 2021</li><li>Proposal for LD PN-PEMS 10 nm specifications : June 2021 (tbc)</li><li>Proposal for a common test procedure for the measurement of particle brake emissions from conventional ICE LDVs: December 2021.</li></ul>

41. GRPE noted the request for a meeting room for a day during the GRPE week in January 2021 to host the workshop on brake emissions.

45. The Chair of IWG on EPPR presented a status report (GRPE-81-22). He updated GRPE on the progress of IWG and introduced GRPE-81-23-Rev.1 on amended ToRs of the IWG. The proposed ToRs included the upcoming activities of the group with a draft new timeline going until 2025. The Chair requested to add interim reporting mid-2022 so GRPE was updated of the progress and latest activities throughout the mandate. The Chair of the IWG on EPPR agreed to this principle.

46. GRPE agreed to revise the ToRs of the IWG on EPPR during the session, as proposed in GRPE-81-23-Rev.1.

47. GRPE acknowledged the progress made by IWG on EPPR and noted the request for a meeting room for one day during the GRPE week in January 2021.

9. Electric Vehicles and the Environment (EVE)
9. (a) UN GTR on the Determination of Electrified Vehicle Power (DEVP)

48. The representative from the United States, drafting coordinator for the proposed new UN GTR, presented GRPE-81-33 as a brief introduction to ECE/TRANS/WP.29/GRPE/2020/12, as amended by GRPE-81-27 on a proposal for a new UN GTR on DEVP. The representative from the Netherlands requested if there was any evidence on the equivalence between Test Procedure 1 (TP1) and Test Procedure 1 (TP2), as described in the proposal. The drafting coordinator of the proposal highlighted tests performed by the Joint Research Centre of the EC on vehicles where both TP1 and TP2 test could be performed. He emphasized the test results were closely related and finally added that in the majority of hybrid vehicle architecture, only one of the test procedure can be performed, depending on software/hardware configurations.

49. The representative from OICA asked how family concepts was being tackled in the proposal, especially thinking about which and how many vehicles should be tested when approaching type approval authorities. The drafting coordinator acknowledged the issue had been raised and that final solutions were still being considered; he wondered if other family concepts from other legislative texts (for example using WLTP family concepts) could be used when applying the proposed UN GTR requirement as part of other regulatory needs. The Chair of GRPE reminded GRPE that UN GTRs are not related to type approval and the relating administrative provisions, and that the proposed UN GTR on DEVP would still need to be transposed into the 1958 Agreement, for example as part of UN Regulation No. 154 on WLTP or UN Regulation No. 85.

9. (b) Other activities of IWG on EVE

51. The Chair of IWG on EVE presented the status report introducing the latest activities of the group (GRPE-81-32). He detailed the latest activities with respect to in-vehicle battery durability. He reminded GRPE that WP.29/AC.3 was expected to grant authorization to develop a new UN GTR on the topic during their June 2020 sessions.

52. He underlined the ambitious timeline agreed for the development of this new UN GTR and explained that given existing circumstances and the necessity to hold virtual meetings to make progress, the IWG decided to meet monthly at least until the end of 2020. He also stressed that the activities gained a lot of attention from various stakeholders and invited any interested parties to join the regulatory elaboration work.

53. The Chair of the IWG on EVE finally briefly updated GRPE on the method for stating energy consumption and the collaboration with the Energy Division of UNECE and its Group of Experts on Energy Efficiency (GEEE).

54. GRPE acknowledged the progress made by IWG on EVE and noted the request for a meeting room for half a day during the GRPE week in January 2021.

12. Vehicle Interior Air Quality (VIAQ)

57. The Chair of IWG on Vehicle Interior Air Quality (VIAQ) presented a status report on the ongoing activities of the group (GRPE-81-08). He detailed the proposed revision to Mutual Resolution No. 3 (M.R.3) as found in ECE/TRANS/WP.29/GRPE/2020/16 containing new provisions to measure interior vehicle air quality, for example the description of the test procedure for emissions entering to the vehicle cabin with exhaust gases.

58. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/16 and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their November 2020 sessions as a proposal for Amendment 1 to M.R.3.

59. The Chair of the IWG on VIAQ also presented GRPE-81-09-Rev.1 on extend ToRs for the IWG. He explained new and forthcoming activities were expected to require an extension until November 2025. The Chair of GRPE requested the IWG to present interim progress and results midway through the proposed term of the IWG so GRPE was well informed about the work and its evolution.

60. GRPE agreed to revise the ToRs of the IWG on VIAQ during the session as proposed in GRPE-81-09-Rev.1., 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 2021.

13. Lifetime compliance

61. Given the circumstances and the limited time for the virtual meeting, GRPE did not consider this agenda item.

14. Priority topics for GRPE activities

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.
