3. Light vehicles
3. (a) UN Regulations Nos. 68, 83, 101, 103, and 154

6. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/2 extending the existing option included in the 06 and 07 into the 05 series of amendments to UN Regulation No. 83 allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP). The representative from Australia raised the point that the modifications made in the 06 and 07 series referred to UN Regulation No. 154 without specifying the level nor the series of amendments that apply, potentially risking the ability to approve vehicles that have a maximum speed below 130 km/h. GRPE noted that when NEDC road loads are calculated from WLTP road loads for use in UN Regulations Nos. 83 or 101, the maximum speed of the derivation tests must be sufficient for both the NEDC and for the specific vehicle.

7. The representatives from the Netherlands and CITA supported the proposal. GRPE endorsed the proposal to amend the 05 series of amendments to UN Regulation No. 83.

8. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/2 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 14 to the 05 series of amendments to UN Regulation No. 83.

9. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 correcting errors in the 06 and 07 series of amendments to UN Regulation No. 83. GRPE endorsed the proposals to amend the 06 and 07 series of amendments to UN Regulation No. 83.

10. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 16 to the 06 series of amendments to UN Regulation No. 83.

11. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/3 and ECE/TRANS/WP.29/GRPE/2021/5 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 13 to the 07 series of amendments to UN Regulation No. 83.

GRPE/2021/3 | UN R83: Proposal for a new supplement to the 06 and 07 series of amendments Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83.
GRPE/2021/5 | UN R83: Proposal for a new Supplement to the 07 series of amendments Proposal to correct an editorial error of exhaust after-treatment system monitoring requirement.

12. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/4 as amended by GRPE-82-17 proposing to correct errors in the 01 series of amendments to UN Regulation No. 101.

13. The representative from the European Commission (EC) requested a clarification about the possibility to submit those proposals as corrigendum instead of supplements. The secretariat clarified that a corrigendum is a document issued to correct an error or errors in a document or publication that has already been issued. He further added that the errors to be corrected were present in the documents issued and can therefore not be considered as corrigendum.

14. GRPE endorsed the proposals to amend the 01 series of amendments to UN Regulation No. 101 and requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/4 and GRPE-82-17, as amended by Annex IV of the session report to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 10 to the 01 series of amendments to UN Regulation No. 101.

GRPE-82-17 | UN R101: Proposal for Supplement to 01 series of amendments This proposal aims at harmonizing the text of UN Regulation No. 83 and UN Regulation No. 101. Furthermore, one error was found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and one wrong cross reference in the 01 series of amendments to UN Regulation No. 101. 1. Harmonization of UN Regulation No. 83 (Annex 4a, Appendix 7b, paragraph 1.) and UN Regulation No. 101 (Annex 7, Appendix 2, paragraph 1.); in Annex 7, Appendix 2, paragraph 1. Vehicles in general are not approved according to UN GTR No. 15, therefore the text phrase of UN R83 is recommended. 2. Correction of wrong reference to Annex 4 instead of Annex 7 of UN GTR No.15; in Annex 7, Appendix 2, paragraph 2.1.(b). 3. When copying the methodology from EU regulation, a ‘.’ was wrongly introduced instead of a ‘-‘ in the formula.
GRPE/2021/4 | UN R101: Proposal for a new supplement to the 01 series of amendments Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in the 01 series of amendments to UN Regulation No.101.

15. The representative from OICA introduced GRPE-82-07 proposing to amend the 06 and 07 series of amendments to UN Regulation No. 83 regarding equivalencies with respect to road load coefficients determination. The representative from Spain asked whether the sub paragraph (2) could be rephrased and clarified. The representative from OICA agreed and intended to prepare a working document for the next session of GRPE in June 2021.

GRPE-82-07 | UN R83: Proposal for a new Supplement to 06 and 07 series of amendments Proposal addressing the conversion of NEDC road load to WLTP road load in cases where the former has already been determined.

16. The representative from OICA introduced GRPE-82-08 proposing to amend the 05 and 06 series of amendments to UN Regulation No. 83 with respect to fuel specification alternatives for Type IV tests. The Chair of the IWG on Particle Measurement Programme (PMP) supported the proposal and agreed that testing with E10 fuel indeed represented a worst case scenario. The representative from OICA agreed and intended to prepare a working document for the next session of GRPE.

GRPE-82-08 | UN R83: Proposal for a new Supplement to 05 and 06 series of amendments Proposal to clarify that the E10 reference fuel may still be used at the worst case for the Type IV test.

17. The representative from EC briefly introduced ECE/TRANS/WP.29/2021/56 and ECE/TRANS/WP.29/2021/57 (together with GRPE-82-10 and GRPE-82-11 as track changes version respectively) that were submitted to the March 2021 session of WP.29 from the representatives from EU and Japan as amendments to UN Regulation No. 154. Both documents proposed changes to correct some mistakes found during the development of Amendment 6 to UN GTR No. 15. GRPE noted the amendments proposals and thanked the Contracting Parties (CPs) involved in the preparation of these documents.

19. GRPE endorsed GRPE-82-38 and requested the secretariat to upload a clean version of GRPE-82-38 under “Documents for reference only” on the GRPE website.

21. GRPE did not receive any new proposals for discussion under this agenda item.

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

22. The Chair of the IWG on RDE introduced the status report of the IWG (GRPE-82-14), informing GRPE on the latest activities from the IWG. She informed that the expected vote from WP.29/AC.1 on a proposal for a new UN Regulation on RDE as adopted by GRPE during its June 2020 session (ECE/TRANS/WP.29/GRPE/81, para. 20.) could not be held because of remaining square brackets that could not be removed due to on-going discussions in the European Union. She did not expect the situation to be solved for the next session of WP.29 in March 2021.

23. She highlighted that the IWG on RDE was considering focussing on the development of the phase 2 of the UN GTR with an improved methodology to represent as much as possible wider conditions of use. She confirmed the interest of the representatives from the United States of America, EU, Japan, China, Canada, India, Republic of Korea and possibly Australia in this development.

24. The representative from the UK and the United States of America supported the approach and agreed with the way forward. The representative from Australia also wished to confirm his interest in participating to the future development steps for the UN GTR.

25. The Chair requested further clarifications about a revision of the authorization to develop the UN GTR on RDE as the IWG now seemed to be considered a new direction for the work. The Chair of the IWG on RDE underlined further discussions would be needed to formalize a revision to the authorization to develop a new UN GTR on RDE and was expecting to update GRPE at its next session in June 2021.

4. Heavy duty vehicles
4. (a) UN Regulations Nos. 49 and 132

26. The representative from EC introduced ECE/TRANS/WP.29/GRPE/2021/6 as amended by GRPE-82-22 proposing a new 07 series of amendments to UN Regulation No. 49. The representative from FSD requested clarifications on the proposal to remove provisions related to On-Board Diagnosis (OBD) from the text. The representative from EC said that there have been considerations to remove OBD provisions from UN Regulation No. 49 to align with existing legislation in the EU, but that they were finally kept in. He suggested to look at the opportunity to include such provisions for the whole vehicle, not only for emission related purposes, possibly in UN Regulation No. 0.

27. The Chair asked whether this topic was being discussed at the IWG on International Whole Vehicle Type Approval (IWVTA). The representative from EC stated that this issue had now been identified and needed to be considered by the IWG on IWVTA. The GRPE Ambassador to the IWG on IWVTA agreed to initiate a discussion on the potential to include OBD and Repair and Maintenance Information (RMI) into UN Regulation No. 0.

28. GRPE endorsed the proposals for a new 07 series of amendments to UN Regulation No. 49 and requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/6 and GRPE-82-22, as amended by Addendum 1 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft 07 series of amendments to UN Regulation No. 49.

GRPE-82-22 | UN R49: Proposal for amendment to the new series of amendments Proposes updates and amendments to proposal to introduce new requirements relating to Auxiliary Emission Strategies, cold engine starts and the use of Portable Emissions Measurement Systems (PEMS) to measure particle numbers
GRPE/2021/6 | UN R49: Proposal for a new series of amendments Proposal to introduce new requirements relating to Auxiliary Emission Strategies, cold engine starts and the use of Portable Emissions Measurement Systems (PEMS) to measure particle numbers.

29. The representative from OICA introduced GRPE-82-23 and GRPE-82-24 proposing some corrections to the 06 and 05 series of amendments to UN Regulation No. 49 respectively. The representative from the EC required further clarifications on the proposal to amend Table 7 that would imply a misalignment with other existing national legislations. GRPE agreed to consider those proposals after further justifications are elaborated by interested stakeholders.

GRPE-82-23 | UN R49: Proposal for supplement to 06 series of amendment Proposes the modifications (essentially corrections of mistakes) are derived from the text of document ECE/TRANS/WP.29/GRPE/2021/7 from Japan, related to UN GTR 04, as modified by Informal Document GRPE- 82-09
GRPE-82-24 | UN R49: Proposal for supplement to 05 series of amendments Proposal makes changes to take into consideration the availability of gases for flame ionization detectors and the linearization of the gas analyzer. UN R49 defines no linearity requirements for humidity sensors. As the humidity content of the intake air is an essential measure for the calculation of the specific exhaust emission, it is important to add requirement for humidity sensor (Reference: ISO 16183 the accuracy of the absolute humidity shall be +- 5%). The reasoning for the other amendments to Table 7 is the following. As the gas divider is a necessary tool to verify the linearization of the gas analyzer it is mandatory that the deviation of the gas divider is lower than that of the instrument under test. In combination with a calibration gas which has an accuracy of 1 % and a gas divider, which has an accuracy of 1 % it is only possible to reach a guaranteed analyzer accuracy of 2 %. Annex 4B – Amendments to paragraph 9.3.3.1 In the automotive industry Helium is used as so fuel gas for flame ionization detectors (FID) to measure Hydrocarbon emissions. In the FID fuel gas Helium is mixed with Hydrogen in a ratio of 40 % H2 and 60 % He. The annual fluctuations of the helium global market lead to an insufficient supply with FID fuel gas, like happened lately during summer 2018. In order to prevent the industry from the fluctuations of the global helium market, the US legislation reacted already in 2014 and allowed the usage of Nitrogen as batch gas for the FID fuel gas.
4. (b) UN Global Technical Regulations Nos. 4, 5, and 10

30. The representative from Japan introduced ECE/TRANS/WP.29/GRPE/2021/7, as amended by GRPE-82-09-Rev.1. The representative from EC highlighted an error that had been omitted, and a correction had been introduced during the meeting in GRPE-82-09-Rev.1.

31. GRPE adopted ECE/TRANS/WP.29/GRPE/2021/7 and GRPE-82-09-Rev.1 as amended by Addendum 2 to this report. GRPE also adopted the technical report (based on extracts from ECE/TRANS/WP.29/GRPE/2021/7) as reproduced in Annex V. GRPE requested the secretariat to submit Addendum 2 and Annex V to WP.29 and Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2021 sessions as draft Amendment 4 to UN GTR No. 4.

GRPE/2021/7 | GTR 4: Proposal for an amendment Proposal to correct the improper or confusing provisions described in Amendment 3 to UN GTR No.4.
4. (c) Worldwide provisions for Heavy Duty vehicles Fuel Economy

32. The representative from OICA stated that activities on this topic remained a priority for the industry and sought guidance from GRPE on how to proceed to initiate activities. The Chair opened the floor for CPs to contribute.

33. The representative from EC stipulated that the position from the EU had not changed since the last time the issue was tackled (ECE/TRANS/WP.29/GRPE/80, paras. 36 and 37). The representative from the US asked whether the intent of this work was to work on CO2 emissions or fuel economy, as opportunities might emerge in the near future about CO2 standards heavy duty vehicles in the region. The Chair also highlighted that other regulatory needs were expected to be needed in the near future regarding alternative powertrain for heavy-duty vehicles. He quoted heavy duty hybrids and range determination of electric trucks as examples where harmonized regulatory provisions are becoming urgently needed. He expected GRPE to play an important role in that in the very near future.

5. UN Regulations Nos. 24, 85, 115, 133, and 143

34. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2021/8, as amended by GRPE-82-25, proposing to amend the 03 series of amendments to UN Regulation No. 24. The representative from EC, after checking with other services from the EC in charge of road worthiness tests, supported the proposal also underlining that a deeper review of the test method would be needed, also for light duty vehicles. The representative from the Netherlands supported the proposal and volunteered to be involved in any follow-up activities that might arise. The representative from OICA confirmed that OICA was looking at similar proposals for light duty vehicles that would be submitted for consideration to GRPE in the next sessions.

35. GRPE endorsed the proposal to amend the 03 series of amendments to UN Regulation No. 24 and requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/8 and GRPE-82-25, as amended by Annex VI of the session report to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft Supplement 6 to the 03 series of amendments to UN Regulation No. 24.

7. Particle Measurement Programme (PMP)

38. The representative from the EC, Chair of the IWG on PMP, introduced GRPE-82-29-Rev.1 and GRPE-82-30, presenting a draft proposal for sub-23nm measurement procedure for heavy duty engines in the laboratory. He mentioned the intention of the IWG on PMP was to finalize the procedure and submit a document that could be used as a reference document for future use in regulatory texts. After considering different document types during the session, he declared this document would be proposed as a draft consolidated resolution in forthcoming sessions of GRPE.

GRPE-82-29/Rev.1 | PMP: Proposal for sub-23nm particles measurement procedure for HD engines This proposal from IWG PMP is based on the PN measurement procedure laid down in UN R49 but should be considered exclusively a technical working document. The purpose of this document is only to discuss within the PMP group the changes/additions needed to modify the PN cut-off size from 23 to approximately 10 nm and to include raw exhaust sampling
GRPE-82-30 | PMP: Explanatory Note for Sub-23nm particle measurement procedure for HD Engines This explanatory note by IWG PMP, updates on the proposals for solid particle number (SPN) measurements for the type approval of heavy-duty engines. The explanatory note addresses (i) the changes to the current SPN23 methodology, (ii) the proposed changes for the second alternative option to extend the particle size detection range to 10 nm particles, (iii) the proposed changes to allow direct SPN sampling with fixed dilution ratio.

39. The Chair of the IWG on PMP introduced GRPE-82-35 giving a status report of the activities of the IWG on PMP. On the topic of non-exhaust emissions, he highlighted the main outcomes from the workshop on brake wear emissions that was held in conjunction with the proper session of GRPE. The representative from the EC agreed that, as outlined during the workshop, a holistic vision to non-exhaust emissions from all sources would be the best solution, and that they were backing the first step to develop a methodology concerning specifically brake emissions test. The representative from the UK stated that they were contemplating such holistic vision to non-exhaust emissions with dedicated research projects on-going.

40. The representative from the Netherlands requested further information about timeline of research projects on brake emission measurement and how the outcomes of such projects would be included in the work of the IWG on PMP. The representative from the UK mentioned that on-going research for on-road measurement of brake emissions were expecting to provide results early in 2022, with further results in 2023. The Chair highlighted the importance of considering real-world patterns to ensure high representativeness of the test methodology. The Chair of the IWG on PMP explained that the simplified test in the lab contemplated by the IWG on PMP would deliver quicker results, and that further results from other testing approaches could be included at a later stage, with a possibility to alter the methodology and timeline.

41. The Chair asked further information about the inclusion of heavy duty vehicles braking system into the methodology. The Chair of the IWG on PMP confirmed the intention to consider heavy duty braking systems, probably with a priority on urban applications initially. He noted that the methodology for heavy duty vehicles braking systems is likely to be significantly altered compared with light duty applications given the different technologies sued in heavy duty braking systems compared with light duty applications.

42. The Chair informed GRPE about discussions that happened during the last WP.29/AC.2 session with respect to the management of intellectual property rights in IWGs. He informed further discussions are expected that might lead to some specific provisions to be included in the Terms of References of IWGs.

43. Finally, the Chair of the IWG on PMP announced that he will hand over the Chair position for the IWG on PMP at the next GRPE session and requested GRPE to approach he IWG on PMP leadership team for any potential candidate for the position. He underlined that a new Chair would be introduced to GRPE at its next session in June 2021.

46. The Chair of IWG on EPPR presented a status report (GRPE-82-34). He detailed a draft request for authorization to develop a new UN GTR on durability of after treatment devices for two- and three- wheeled motor vehicles (GRPE-82-26-Rev.1). He also stated that this new UN GTR, once finalized, would also potentially be transposed into a UN Regulation. The secretariat asked whether this transposition would likely amend UN Regulation No. 40 or be included into a new UN Regulation. The Chair of the IWG on EPPR said this point was still being considered.

47. GRPE adopted GRPE-82-26-Rev.1, as amended by Annex VII of the session report, and requested the secretariat to submit it to WP.29 and Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2021 sessions as draft request for authorization to develop a new UN GTR on durability of after treatment devices for two- and three- wheeled motor vehicles.

11. International Whole Vehicle Type Approval (IWVTA)

57. The GRPE ambassador to the IWG on IWVTA introduced GRPE-82-12 on the inclusion of GRPE-related UN Regulations into IWVTA. He reminded that the 01 series of amendments to UN Regulation No. 154 was expected to enter into force during the summer and could therefore be included into UN Regulation No. 0 at its next update during the November 2021 session of WP.29, and that actions would be required by GRPE if this process was to be stopped.

58. The representative from EC sought clarifications about the inclusion and timing of the candidate UN Regulations into UN Regulation No. 0. The GRPE ambassador to the IWG on IWVTA clarified how the process developed and required information on the applicability of the 01 series of amendments to UN Regulation No. 154 in the EU once entered into force. The representative from EC recalled the specific provisions included into UN Regulation No. 154 to avoid misapplication of UN Regulation No. 154 and requested GRPE to postpone the inclusion of UN Regulation No. 154 into UN Regulation No. 0. The representative from Switzerland supported this request.

59. GRPE requested the GRPE ambassador to the IWG on IWVTA to ask for removal of UN Regulation No.154 and forthcoming UN Regulation No. [XXX] on RDE from the list of candidates for IWVTA Phase 2. GRPE also required the ambassador to seek guidance from the IWG on IWVTA on how to include provision related to Repair and Maintenance Information and On-Board Diagnosis into UN Regulation No. 0. (see para. ‎0).

13. Lifetime Compliance

62. The representative from the Netherlands informed GRPE about their intention to initiate a discussion at GRPE in forthcoming sessions about lifetime compliance as done at the European level as part of the Euro 7/VII discussions.

14. Priority topics for GRPE activities

63. The Chair introduced GRPE-82-06-Rev.1 as the revised GRPE priority list including the latest progress made during this session. In particular, the Chair congratulated GRPE and all the stakeholders involved for the early delivery of the 07 series of amendments to UN Regulation No. 49. GRPE agreed to provide a clean version of GRPE-82-06-Rev.1 to WP.29/AC.2, when requested.

64. The representative from OICA wondered if hydrogen propulsion for heavy duty applications (whether using fuel cells or internal combustion engines) was to be included in the list of priorities with hydrogen likely to play a role in the future of transportation energy supply. He added a performance standard might be needed soon.

65. The Chair agreed that there are numerous white spots in heavy duty alternative powertrain types legislation on topics related to energy consumption and emissions. The representative from the Netherlands for example raised the quickly-emerging need for a procedure to determine range of battery electric heavy duty vehicles for eligibility criteria for financial subsidies decided by some governments. The representative from OICA also highlighted power determination procedures could be needed as powertrain concepts often differs from the existing ones.

66. The representative from EC proposed to organize a dedicated workshop on upcoming legislative needs for future heavy duty powertrains. The representative from OICA supported the idea and stood ready to co-organize such workshop with the assistance and support from the secretariat.

67. GRPE welcomed the initiative and agreed to organize such workshop as part of the next GRPE session in June 2021.

15. Any other business

69. The representative from Australia introduced GRPE-82-13 on the consultation process on-going in the country for the future emission legislation for light and heavy vehicles. The representative from EC required some information about the consideration to propose the latest 07 series of amendment to UN Regulation No. 49 (instead of the 06) for the future heavy vehicles’ legislation. The representative from Australia clarified the 06 series of amendment to UN Regulation No. 49 was the latest available when the proposal was drafted and amending this (upon decision from transport minister) would require starting a whole new process.

70. The representative from EC asked whether feedback to the consultation was expected from GRPE and its stakeholders. The representative from Australia said the consultation was primarily aimed at domestic stakeholders, and the he would be thankful to receive feedback from international stakeholders too.

71. The representative from OICA recalled that Australia was not a contracting party to UN Regulation No. 83 and asked if this was expected to change if Australia was to adopt UN Regulation No. 83 as part of its emission legislation. The representative from Australia said that Australia would in principle become a contracting party to UN Regulation No. 83 if adopted as part of this legislative process.
