2. Report on the last session of the World Forum for Harmonization of Vehicle Regulations (WP.29)

7. The secretariat introduced GRPE-86-04 and reported on relevant items discussed during the 84th annual session of the Inland Transport Committee, in particular with respect to decision 34.© where ITC “invited its Working Parties to submit to the secretariat until 14 October 2022 their ongoing contributions, future plans and suggestions in support of climate change mitigation”, and decision 48. where ITC “requested WP.5 to take into consideration the new trend towards electric charging infrastructure and, in coordination with the chairs of the relevant working parties, to prepare a first assessment of issues that need addressing in the realm of the ITC to be presented at the 85th session of the ITC” .

8. GRPE agreed to let the GRPE leadership team coordinates inputs on its behalf on those two requests from ITC. The Chair and secretariat prepared a draft contribution to be submitted to ITC (GRPE-86-47). GRPE also invited the Informal Working Groups (IWGs) on Electric Vehicles and the Environment and on Life Cycle Analysis (LCA) to contribute to the relevant topic, if appropriate. The Chair also invited any interested party to approach him in case they would want to provide inputs to any of these documents.

9. The secretariat informed about relevant items discussed during the 186th sessions of the World Forum for Harmonization of Vehicle Regulations (WP.29). He referred to ECE/TRANS/WP.29/1164 for further details.

10. The representative from France asked further information on the request from WP.29 for each GR to perform a screening of UN Regulations, GTRs and Rules with regards to their fitness for Automated Driving Systems (ADS), incl. for driverless systems, and asked whether a dedicated task force would be needed, as done by other GRs. The representative from the US raised the questions about how ADS systems will impact typical driving behaviours, in terms of speed, acceleration. The representative from OICA shared a concrete example where regulation would need to be amended to give the permission for autonomous vehicle to drive emission test cycles. The representative from the European Commission (EC) stated she was hesitant to create a dedicated task force on this topic, given the workload of GRPE and invited GRPE to consider the best time to do it in the future.

11. The Chair invited all interested parties to provide a list of potential impacted regulations by ADS, to be shared as informal documents during the next session of GRPE in January 2023.

GRPE asked all interested parties to provide written comments to the secretariat, with the intention still being to prepare a working document for the January 2023 session of GRPE.

GAR note: At the time of this writing, document GRPE-86-44 had not been published by the GRPE secretariat. You may wish to consult the list of informal documents for this GRPE session in case the document has since been made available.

GRPE-86-07 | UN R83 : Presentation on development of 08 series of amendments

26. The representative from OICA introduced GRPE-86-31 seeking advice from GRPE on the Introductory Provision in the newly adopted 02 series of amendments to UN Regulation No. 154 The representative from OICA agreed to prepare an updated reference document (GRPE-86-48) amending GRPE-81-29-Rev.1. GRPE-81-29-Rev.1 can be found in the “Documents for reference only (GRPE)” section of the GRPE webpage. The representative from Japan also sought clarification about the entry into force of the 03 series of amendments to UN regulation No. 154, expected in October. The secretariat said he will collect relevant information to be communicated to the representative of Japan.

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)
GRPE-86-31 | UN R154 : Presentation on concerns the introductory provision in 02 series of amendments
GRPE-86-48 | Clarification of points regarding UN Regulation No. 154 Informal document GRPE-81-29 rev 1 was submitted to GRPE in June 2020 to clarify some elements surrounding the introduction of UN Regulation No. 154. This paper is updated here to add an additional clarification of the introductory provisions in the newly adopted 02 series of amendments. This document with tracked changes in <a href="https://unece.org/sites/default/files/2022-07/GRPE-86-48e_track.docx" target="_blank">word format</a> and <a href="https://unece.org/sites/default/files/2022-07/GRPE-86-48e_track.pdf" target="_blank">pdf version</a> is also available.
3. (b) UN Global Technical Regulations Nos. 15 and 19

27. The representative from Clean Air Association introduced GRPE-86-20 proposing to amend UN GTR No. 15 and its definition of defeat device. The representative from the EC informed that litigation cases where still on-going with respect to this definition, and suggested all legal cases are settled before looking at a potential amendment to this definition. The representative from the UK added that the Court of Justice of the European Union (CJEU) has clarified that the notion of damage should be interpreted as sudden, and wondered if the proposal was necessary given that the CJEU ruling clarified the subject matter.

28. The representative from Japan, former secretary to the IWG on WLTP, added that the definition had been simplified in the latest amendments to UN GTR No. 15. The representative from the Netherlands, former Chair of the IWG on WLTP, added indeed that the exemptions to the definition were moved to another part of UN GTR No. 15, but remained.

29. The Chair acknowledged this was an important issue, and that some regions have clarified the matter, and that in GRPE many on-going activities (such as the forthcoming UN Regulation on RDE or the finalization of the 08 series of amendments to UN Regulation No. 83) could potentially have an impact on this definition. He invited GRPE to potentially re-visit the topic when discussing the 08 series of amendments to UN Regulation No. 83.

GRPE-86-20 | UN GTR15: Proposal for amendment Proposal:<ol class="alpha"><li>To ensure and promote a high level of protection for the environment and human health. The underlying purpose of paragraph 3.5.7, when read in conjunction with paragraph 5.3.4, is to ensure a high level of protection for environment and human health. In making clear and encouraging the proper application of these provisions, this amendment furthers the aims sought to be achieved through paragraphs 3.5.7 and 5.3.4 of the Regulation.</li><li>To ensure and promote consumer confidence in the quality of vehicles subject to UN GTR No. 15. Given the widespread use of defeat devices (justified or otherwise) in the preceding years, consumer confidence in regulatory regime’s ability to conform with its underlying purpose has dwindled. This amendment makes clear and encourages the proper application of the text of the Regulation with respect to defeat devices. In doing so, consumers will be more confident in proper application of the provision.</li><li>To promote legal certainty. It is recognised that it is for the members of the WP.29 to interpret the provisions of Regulations at a national level. However, it is critical that Regulations of the WP.29 are clear and precise. The addition of the term "immediate" as an adjective to the term "damage" in subparagraph (a) to section 3.5.7 would make it clear that delayed or gradual damage to the engine does not justify the use of a defeat device.</li></ol>
3. (c) Worldwide harmonized Real Driving Emissions test procedure

30. The representative from the European Commission, Chair of the IWG on RDE, introduced GRPE-86-29 providing an update about the latest intention with the finalization of the new UN Regulation on RDE. She informed that more changes beyond the remaining square brackets would be needed and that a final text was expected to be available in the first weeks of July 2022. She kindly requested GRPE to accept a post session submission, and the consideration of the informal document through a written procedure over the summer.

31. GRPE agreed to consider a draft proposal for a draft new UN Regulation on RDE as post session informal document GRPE-86-45 to be shared by the secretariat with all GRPE participants mid July 2022. GRPE asked all interested parties to provide written comments to the secretariat before 19 September 2022, to prepare a working document for the January 2023 session of GRPE.

GRPE-86-29 | UN R RDE (real driving emissions): Presentation on developments
GRPE-86-45 | RDE: Updated draft text on the approval of vehicles with regard to real driving emissions This document is also available with tracked changes in <a href="https://unece.org/sites/default/files/2022-07/GRPE-86-45e_track.docx" target="_blank">word format</a> and <a href="https://unece.org/sites/default/files/2022-07/GRPE-86-45e_track.pdf" target="blank">pdf version</a>.
4. Heavy duty vehicles

32. GRPE agreed to consider a presentation from the representative from the US on the recent proposed rule for Heavy Duty tailpipe emissions (GRPE-86-33) released by US EPA. The representative from the European Commission asked about how the future share of zero-tailpipe emission vehicles (ZEVs) had been calculated, and which kind of ZEVs had been considered. The representative from the US clarified the mandates in certain parts of the US, such as in California had been used as a reference and that no fuel cell vehicles were assumed in the time frame studied. He also added that for example, school buses were assumed to be electrified first, as a vehicle category in which the payback time would be quick and the driving patterns would match the vehicle technical specifications.

33. The Chair asked whether during the development of the US proposed rule, existing UN legal instruments such as UN GTRs Nos. 4 or 10 were taken into consideration. The representative from the US confirmed that the World Heavy-Duty test Cycle (WHDC) was considered but abandoned during the consultation process, as well as off cycle emissions where alignment would still require additional changes in the procedure. He confirmed that the US (through the US EPA) remained committed to harmonize regulation through GRPE.

34. The representative from the European Commission offered to introduce the Euro7/VII proposal at the next session of GRPE, proposing to hold any further discussions about necessary changes in UN GTRs until then. The Chair highlighted the importance of harmonizing provisions, especially on the heavy duty sectors, and invited GRPE to reconsider this topic at the forthcoming sessions of GRPE.

4. (a) UN Regulations Nos. 49 and 132

35. The representative from OICA introduced GRPE-86-25 as an update about the inclusion of hydrogen as a fuel in UN Regulations No. 49 and 85 and informed GRPE that the consideration of ECE/TRANS/WP.29/GRPE/2022/20 as amended by GRPE-86-13 would be postponed until the next session of GRPE. The representative from the European Commission confirmed that no vehicles had been identified for validation tests and that the validation test campaign was expected to be finalized by the end of 2022. GRPE agreed to postpone the consideration of this issue to forthcoming sessions of GRPE.

The representative from the Netherlands sought advice on how to deal with liquified hydrogen safety issues, as the topic has not been included yet in UN Regulation No. 134 (but is present in UN GTR No. 13) which deal with safety issue for hydrogen vehicles. The Chair indicated he would raise the issue during the next session of WP.29 to get the latest information on this topic.

4. (b) UN Global Technical Regulations Nos. 4, 5 and 10

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

4. (c) Worldwide provisions for Heavy Duty vehicles Fuel Economy

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

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

39. The representative from OICA introduced GRPE-86-25 as an update about the inclusion of hydrogen as a fuel in UN Regulations No. 49 and 85 and informed GRPE that the consideration of ECE/TRANS/WP.29/GRPE/2022/21 would be postponed until the next session of GRPE. GRPE agreed to postpone the consideration of this issue to forthcoming sessions of GRPE.

GRPE/2022/21 | UN R85: Proposal for a Supplement Proposal to allow for the use of hydrogen (H2) as fuel for type approval of heavy-duty vehicles.

40. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2022/22 and ECE/TRANS/WP.29/GRPE/2022/23 on reference fuels allowed to be used when performing tests according to UN Regulations Nos. 24 and 85. The representative from the UK found the proposals acceptable and would be willing to adopt after removal of the square brackets. The representative from the European Commission required proposals to be bundled so regulatory texts are not updated at every GRPE session, that increases the administrative burden and might be perceived as bad legislative development. The representative from Italy stated he would be willing to adopt the proposals in this session to facilitate adoption and certification processes around the globe. The representative from the European Commission suggested to only adopt ECE/TRANS/WP.29/GRPE/2022/22 in this session and to bundle all proposals to amend UN Regulation No. 85 at forthcoming sessions of GRPE, including ECE/TRANS/WP.29/GRPE/2022/23. GRPE agreed with this approach.

41. GRPE adopted ECE/TRANS/WP.29/GRPE/2022/22 as amended during the session and reflected in Annex VII to the session report and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2022 sessions as draft new supplement to the 03 series of amendments to UN Regulation No. 24 (Visible pollutants, measurement of power of C.I. engines (Diesel smoke)).

GRPE/2022/22 | UN R24: Proposal for a Supplement to the 03 series of amendments Proposal to allow for the usage of the reference fuel required for emission testing when the manufacturer applies for UN R85 and/or UN R49 type approval at same time.
GRPE/2022/23 | UN R85: Proposal for a Supplement Proposal to explicitly permit the usage of the reference fuel required for emission testing when the manufacturer applies for UN R24 and/or R49 type approval at same time.
6. Agricultural and forestry tractors, non-road mobile machinery
6. (a) UN Regulations Nos. 96 and 120

42. The representative from EUROMOT introduced GRPE-86-06 updating GRPE on the inclusion of hydrogen as a fuel in UN Regulation No. 96. The Chair asked about the scope difference in UN Regulation No. 96 versus the European legislation, and if GRPE should attempt to harmonize the scope in both regulatory frameworks. The representative from EUROMOT did not see it feasible to include inland waterways into the 58 Agreement given its title on “wheeled vehicles” and clarified its intention in GRPE-86-06 was to acknowledge the scope difference, not to attempt to harmonize it.

43. The representative from the Netherlands sought clarifications about a similar validation test campaign being planned for non-road mobile machinery as the one planned for on-road heavy duty vehicles for the use of hydrogen in internal combustion engines (see para. ‎39). The representative from EC stated their willingness to hold bilateral discussions with EUROMOT to find the best way forward to include non-road vehicles into the validation test campaign, if possible.

7. Particle Measurement Programme (PMP)

45. The representative from the European Commission, Chair of the IWG on PMP, introduced GRPE-86-34 giving a status report of the activities of the IWG on PMP. He asked his colleague to provide an update on all matters related to non-exhaust particulates measurement and the latest development of the UN GTR on brake particulate emissions. The representative from OICA highlighted the high variability of brake emission results during the inter-laboratory study, and wondered if such variability would be accounted for in the mission limits, if set, and asked about potential measures to reduce variability. The representative from the European Commission clarified that no emissions limits are expected to be included in the UN GTR that will focus on a harmonized test method. He highlighted that during the inter-laboratory test, only one laboratory was fully compliant with the provision set out in the Task Force 3 protocol. He expected the variability would drastically improve when the final procedure is released and all laboratories are compliant with the provisions. He kindly requested GRPE to accept a post session submission, and the consideration of the informal document through a written procedure over the summer.

46. The representative from OICA said that it is the third informal document that is expected to be submitted via written consultation, highlighting the challenges that this might pose to keep track of the progress and requested for the possibility to hold additional meetings, if need be, before the submission of working documents. The Chair reminded GRPE that the practice to have informal document consideration then working documents at the forthcoming session was not mandatory, and GRPE might be willing to show some flexibility when needed. The representatives from Sweden and the UK supported the timeline proposed by the IWG on PMP.

47. GRPE agreed to consider a draft proposal for a draft new UN GTR on brake particulate emissions as post session informal document GRPE-86-46 to be shared by the secretariat with all GRPE participants mid July 2022. GRPE asked all interested parties to provide written comments to the secretariat before 19 September 2022, to prepare a working document for the January 2023 session of GRPE.

48. The representatives from France and the European Commission, Co-Chairs of the Task Force on Tyre Abrasion (TFTA), introduced GRPE-86-23 presenting the activities of the TFTA since its recent inception. The Chair thanked the update and asked for such regular updates to GRPE on this topic.

8. (c) Environmental and Propulsion Performance Requirements (EPPR) for L-category vehicles

51. The Co-Chairs of IWG on EPPR presented a status report (GRPE-86-26). They updated GRPE on the latest activities of the group and also introduced updated Terms of References for the IWG on EPPR (GRPE-86-27-Rev.3). GRPE adopted GRPE-86-27-Rev.2 to extend the interim leadership team by 6 months.

9. Electric Vehicles and the Environment (EVE)
9. (a) UN GTR No. 21 and [22]

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

9. (b) Other activities of IWG on EVE

53. The Chair of IWG on EVE presented the status report introducing the latest activities of the group (GRPE-86-37). He explained the latest work starting on including heavy duty into UN GTR No. 22 and the growing challenges it would pose given the lack of reference value to base the durability on. He informed GRPE that the development activities might take longer than for light duty vehicles and asked GRPE for patience during this process. He confirmed the IWG on EVE was nevertheless committed to deliver a new amendment to UN GTR No. 22 in a timely manner. The Chair of GRPE thanked again the IWG on EVE for their work and dedication.

10. Mutual Resolution No. 2 (M.R.2)

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

11. International Whole Vehicle Type Approval (IWVTA)

55. The GRPE ambassador to the IWG on IWVTA introduced GRPE-86-21-Rev.1 and GRPE-86-22 updating GRPE on the latest information from the IWG on DETA about the implementation of the Unique Identifier (UI) in UN Regulations pertinent to GRPE. He suggested to take a cautious approach to forbid UI in case of doubts and to also monitor the developments of DETA and UI closely. The representative from the UK agreed with this cautious approach and highlighted the importance of markings for after-market purposes.

56. The representative from the European Commission noted that in some markets the smoke coefficient in UN Regulation No. 24 was obsolete, and therefore dedicated marking information would no longer be needed in those markets. The representative from OICA added that despite the withdrawal of the obligation to perform smoke test for some engines, the need to display a default value on the label was still needed.

57. Once agreed by GRPE, The GRPE ambassador to the IWG on IWVTA said he would develop draft proposals to amend relevant UN Regulations to authorize or not the use of UI. The secretariat asked about the information contained in the summary document. The GRPE ambassador to the IWG on IWVTA replied this was still being discussed, but that the fundamental concept was very open.

58. The Chair asked if the UI is not forbidden in a specific UN regulation, whose decision it is to switch to UI instead of E marking. The GRPE ambassador to the IWG on IWVTA clarified that it would be up to the applicant (usually OEMs) to choose whether to use UI or E marking, with the support of Type Approval Authorities that would be the only ones to be able to create new UI.

59. The Chair invited all relevant experts for each GRPE-related UN Regulation to approach the ambassador to provide their views on the need to forbid UI in the respective UN Regulations, with an update from the ambassador expected at the next session of GRPE. The GRPE ambassador to the IWG on IWVTA also informed about some potential issue with the inclusion of the 03 series of amendments to UN Regulation No. 154 in UN Regulation No. 0 and said he would update the GRPE leadership team if there is any urgent issue to be looked at.

14. Priority topics for GRPE activities

68. The Vice-Chair introduced GRPE-86-41 as his main takeaways from the Life Cycle Assessment (LCA) workshop that took place earlier during the week. The representative from Japan introduced GRPE-86-17, the representative from the Russian Federation introduced GRPE-86-19, the representative from the US introduced GRPE-86-40 and the representative from CLEPA introduced GRPE-86-38 on their respective positions with respect to the inclusion of LCA in GRPE activities and the creation of a dedicated IWG to work on the topic.

69. The representative from the European Commission supported the creation of an IWG on LCA, highlighting that the conditions are not yet met to plan to deliver on a UN GTR. Finalization of ToRs, scope and timing of the activities would be considered during the first meeting of the IWG on LCA and introduced for adoption during the next session of GRPE.

70. The representative from the UK supported LCA to be considered by GRPE and to initiate an IWG on the topic. He highlighted the need to have a clear view on the aims, targets and objectives of the IWG. He also was not supportive of any regulatory deliverables at this stage, and that a mutual resolution, for example, could be drafted once a complete LCA picture has been finalized. He concluded that new expertise from outside of GRPE would be needed.

71. The representative from Sweden thanked Japan and the Republic of Korea for the initiative and supported the creation of a dedicated IWG. He also shared his view that regulatory provisions should not be aimed in a first step, and that the IWG should initially focus on information sharing and deliver a resolution.

72. The representative from Switzerland also supported the initiative as an essential activity for GRPE and showed his willingness to be involved. He also stressed on the importance of looking at air quality, water and soil LCA impacts on top of GHG which is the primary target of the IWG on LCA.

73. The Chair indicated that the draft ToRs, as shown in GRPE-86-18-Rev.1, would be discussed during the first meeting of the IWG on LCA and the next session of GRPE.

74. GRPE agreed to create a new IWG on LCA and to include LCA in the GRPE list of priorities.

75. The representative from Japan indicated that Japan would be happy to host the first IWG meeting expected in October 2022, thought a hybrid meeting configuration, with the support of the secretariat. He indicated the draft ToR would be discussed during the meeting. The secretariat offered its support to organize the first meeting of the IWG on LCA.
