2. Mr. Rijnders, Chair of GRPE, opened the meeting and welcomed the participants. GRPE adopted the provisional agenda of the eightieth session (ECE/TRANS/WP.29/GRPE/2020/1), as updated and consolidated in GRPE-80-06-Rev.4. GRPE took note of GRPE-80-01-Rev.1 on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

4. The secretariat introduced GRPE-80-02, announcing that the next GRPE session would take place on from 9 to 12 June 2020 and recalling the corresponding deadline (17 March 2020) 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 June 2020 GRPE session. The secretariat also reminded all participants, including those in possession of long duration badges, to please register in order to appear on the list of participants.

5. The secretariat introduced GRPE-80-03 and reported on relevant items discussed during the 178th and 179th session of the World Forum for Harmonization of Vehicle Regulations (WP.29). He referred to ECE/TRANS/WP.29/1147 and ECE/TRANS/WP.29/1149 for further details.

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

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

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

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

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

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

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

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

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

GRPE adopted the provisional agenda of the eightieth session (ECE/TRANS/WP.29/GRPE/2020/1), as updated and consolidated in GRPE-80-06-Rev.4. GRPE took note of GRPE-80-01-Rev.1 on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

8. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2020/2 superseded by GRPE-80-07 correcting references and streamlining the definition of mono-fuel gas vehicles. The representatives from Italy, the Netherlands and France supported the proposal. GRPE adopted the proposal to amend the 06 and 07 series of amendments to UN Regulation No. 83, as amended by Annex V to the session report.

11. GRPE endorsed the three proposals to amend the 06 and 07 series of amendments to UN Regulation No. 83 and requested the secretariat to submit Annexes V, VI and VII to the session report to WP.29 and AC.1 for consideration and vote at their June 2020 sessions as draft Supplements 14 and 11 to the 06 and 07 series of amendments to UN Regulation No. 83 respectively.

9. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2020/5, as amended by GRPE-80-08 and GRPE-80-16. Those documents introduced new definitions and clarified ‘permanent emission default mode’ of OBD systems. GRPE adopted the proposal to amend the 06 and 07 series of amendments to UN Regulation No. 83, as amended by Annex VI to the session report.

65. The expert from OICA, ambassador of GRPE at IWVTA also looking at the matters of the Database for Exchange of Type Approvals (DETA), introduced GRPE-80-09 showing the latest progress in the deployment of DETA. Another representative from OICA requested information on the notification process for manufacturers and employees changing assignments. The secretariat confirmed the DETA administrators should be contacted to provide updated and ensure undisrupted access to DETA. The secretariat also notified GRPE that a full answer from the UN General Assembly resolution on the request to host DETA under UN regular budget would be provided during the next session of WP.29 in March 2020.

66. The ambassador of GRPE at IWVTA also introduced GRPE-80-14 on the latest activities of the IWG on IWVTA. He highlighted some cases of potential misinterpretation on the transitional provisions with concrete examples related to GRPE. GRPE noted the progress from IWGs on DETA and IWVTA and thanked the ambassador for his implication.

20. The representative from CITA introduced GRPE-80-10 proposing amendments to the 07 series of amendments to UN Regulation No. 83. He also introduced GRPE-80-11 and GRPE-80-12 that are of similar content proposing to amend UN Regulations Nos. 24 and 96 respectively. All three proposals sought to improve the design of vehicles to make tampering of emissions systems more difficult and to facilitate its detection. The representatives from Italy, the United Kingdom of Great Britain and Northern Ireland and EC highlighted the importance and relevance of the topic and required more time and deeper impact assessments to gauge the potential consequences of such new provisions.

21. The representative from Australia wondered why the representative of CITA had not proposed amendments to UN Regulation No. 49 along the same lines and asked if all the proposals might be tackled as a whole for all vehicle types. The representative from CITA explained that GRPE-80-10, GRPE-80-11 and GRPE-80-12 represented a first step and the other UN Regulations would be looked after at a later stage.

22. The representative from Euromot reiterated that all technical changes require a technical assessment and that in the case of Non-Road Mobile Machinery (NRMM) engines, many principles detailed in the proposal from CITA were already addressed today (e.g. on software version and emission control system). The representative from CITA welcomed this statement and the comments received and he stated CITA will further work to improve those proposals.

23. The representative from the Netherlands requested CITA to especially further elaborate the justification part of the proposals to include for example root-cause assessment and/or cost/benefit analysis to better understand what CITA wants to achieve and to assess the effectiveness of the proposals. The representative from EC highlighted the consensus from all stakeholders that the issue of tampering prevention is important and urgent but that further discussions would be required, for example in a dedicated group to work in-depth on the topic. The Chair confirmed the sense of importance especially with the risk that tampering is undermining all the efforts made at type approval.

24. The representative from OICA agreed the issue needed to be looked at and encouraged not to place all the burden and car manufacturers and to have a holistic view, for example by looking at new tools to analyse at environmental performance on a more regular basis and by complementing the administrative provisions.

25. GRPE agreed to keep the topic on the agenda and to create a dedicated agenda item on lifetime compliance from the next session of GRPE in June 2020. GRPE also agreed to invite a representative from GRVA to share the latest progress on the work of the Task Force on Cyber Security and Over The Air (OTA) software updates (CS/OTA) operating under the auspices of GRVA, on Integration of Regulation X Software Identification Number (RxSWIN).

38. The expert from OICA informed GRPE that OICA withdrew ECE/TRANS/WP.29/GRPE/2020/8 from consideration by GRPE. A recent better understanding of the issue following informal discussions with various stakeholders showed the proposal needed to be reconsidered.

39. The representative from CITA introduced GRPE-80-11 together with GRPE-80-10 and GRPE-80-12, as all documents were of similar nature (see para. 20).

46. The representative from Russia introduced GRPE-80-13 showing the importance of tyre and road wear emissions into the non-exhaust particulate emission mix. The report of the Russian Federation presented the comparative results of PM emissions from various vehicle systems, which were characterized by the following correlation: 28% with exhaust gases, 7% from braking systems, 12% from tyres and 53% from roadway, according to the materials of the research conducted in the Russian Federation and the UK. On this basis, He expressed the necessity for the tyre manufacturers and road construction services to revise the existing production technologies for tyres and roadway and to consider new materials and technologies to minimize the use of materials containing highly hazardous cancerogenic substances to improve health of population in large cities and elsewhere.

47. The representative from the Netherlands asked if the sources of particulate emission from transport were compared with other sources. The representative from Russia said there is research underway to have a broader look at all sources of emissions and that national inventories were performed at the national level that are providing information about the source of particulate emissions for the main sectors.

48. The representative from Australia highlighted that tyre and road wear emissions also highly depended on road surface technology and wondered if the results presented by Russia had been shared with the World Road Association. The representative from Russia replied that this information was now shared with WP.29 and that road associations were also collaborating with the World Health Organization (WHO) on those issues. The Chair welcomed the emergence of those issues to better understand the importance of the various sources of emissions and encouraged to further share such outcomes and inform all relevant stakeholders.

49. The Chair of the IWG on PMP asked if the study from Russia also looked at the particulate size distribution, as some literature seemed to indicate road and tyre wear particulate size were quite large. The representative from Russia agreed road wear particulate size was typically above 100 nm, but that many studies including the one from Russia considered small particulates in their findings.

65. The expert from OICA, ambassador of GRPE at IWVTA also looking at the matters of the Database for Exchange of Type Approvals (DETA), introduced GRPE-80-09 showing the latest progress in the deployment of DETA. Another representative from OICA requested information on the notification process for manufacturers and employees changing assignments. The secretariat confirmed the DETA administrators should be contacted to provide updated and ensure undisrupted access to DETA.

10. The representative from OICA introduced GRPE-80-18-Rev.1 allowing the usage of alternative road load power determination techniques, which have been derived from those determined in UN GTR No. 15 and UN Regulation on WLTP, to amend the 06 and 07 series of amendments to UN Regulation No. 83. GRPE adopted the proposal to amend the 06 and 07 series of amendments to UN Regulation No. 83, as amended by Annex VII to the session report.

11. GRPE endorsed the three proposals to amend the 06 and 07 series of amendments to UN Regulation No. 83 and requested the secretariat to submit Annexes V, VI and VII to the session report to WP.29 and AC.1 for consideration and vote at their June 2020 sessions as draft Supplements 14 and 11 to the 06 and 07 series of amendments to UN Regulation No. 83 respectively.

81. The representative from the Republic of Korea introduced GRPE-80-19 presenting Case studies on analysis of light duty vehicle exhaust gas control signal in Korea. The Chair thanked the representative from Korea for his interesting presentation and welcomed national initiatives on vehicle emissions control measurements to be presented at GRPE.

40. The representative from Liquid Gas Europe introduced GRPE-80-20 correcting errors in ECE/TRANS/WP.29/2019/45. The representative from Italy agreed ECE/TRANS/WP.29/2019/45 contained some errors that needed to be addressed in the fastest way possible by the secretariat. The secretariat submitted GRPE-80-20 as ECE/TRANS/WP.29/2020/49 as a Proposal for Corrigendum 1 to Supplement 8 to UN Regulation No .115 (LPG and CNG retrofit systems) that was to be considered by WP.29 and AC.1 at their March 2020 sessions.

67. The Chair of IWG on Vehicles Interior Air Quality (VIAQ) presented a status report on the ongoing activities of the group (GRPE-80-23). He also encouraged GRPE to review and provide comments and feedback on the draft Revision 1 to Mutual Resolution No. 3 (GRPE-80-21 and GRPE-80-22). He informed about on-going collaboration and information exchange with other groups working on vehicle interior air quality measurement procedures.

68. The representative from OICA asked if a Round Robin tests had been carried to confirm the draft Revision 1 to M.R.3 works and is practical. The Chair of IWG on VIAQ confirmed some tests in different facilities showed good correlation between the results.

14. The representatives from the European Commission (EC), Chair of the IWG on WLTP and drafting coordinator, introduced GRPE-80-24 and GRPE-80-37 on the status report of the IWG on WLTP and the steps achieved to finalize the transposition of UN GTR No. 15 into a new UN Regulation. The Chair of the IWG on WLTP highlighted the progress made and impressive achievements of the last 10 years aiming at global harmonization, taking into consideration the fragmented world at that time. He emphasized all stakeholders involved had put considerable amount of resources to reach the best possible results into the work that was fully back by GRPE and WP.29 over the years. The Chair expressed its deepest appreciation to the tremendous efforts that have been delivered into developing WLTP-related legislative activities with the full support from GRPE and WP.29, and also during the session to finalize the documents on time for a consideration by GRPE.

35. The representative from OICA introduced GRPE-80-25 containing draft amendments to UN GTR No. 4, mainly correcting errors found in some formulas in the latest version of the text. GRPE welcomed the proposal and was looking forward to receiving a working document at the next session of GRPE in June 2020.

36. The expert from OICA introduced GRPE-80-26 summarizing the outcome of the Heavy Duty Fuel Economy (HDFE) workshop held earlier during the GRPE week. He highlighted there is continuous interest from contracting parties on the topic of harmonization of HDFE, but that, to date, no contracting parties were in the position to sponsor the creation of a new IWG on the issue.

37. The Chair confirmed that the situation, where there is interest to work on a topic but no resources are available, was unfortunate. He welcomed the proposal from OICA to have an ad-hoc group open to all interested parties to work on the development of harmonized guidance provisions that could then be considered by GRPE. He requested more information about the timeframe for the initiation of those activities. The representative from OICA highlighted that a more detailed planning will be developed in due course and assistance from the secretariat would be sought to share the information with GRPE.

52. The Chair of IWG on Environmental and Propulsion Performance Requirements for L-category vehicles (EPPR) introduced GRPE-80-32 containing a draft Amendment 1 to Un GTR No. 18 together with the EPPR status report (GRPE-80-27, see para. 53).

53. The Chair of IWG on EPPR presented a status report (GRPE-80-27). He updated GRPE on the progress of IWG and introduced the upcoming activities of the group with a draft new timeline going until 2026. The representative from the Netherlands asked if the plan to work on propulsion unit performance would include electrified powertrain. The Chair of the IWG on EPPR confirmed that it would be the case.

54. The representative from India also added the new plans for EPPR activities would be closely looking at all L categories, included three- and four-wheelers in their forthcoming activities. The Chair congratulated the IWG on EPPR for their intense activities and the approach adopted to develop new texts.

55. 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 June 2020.

43. The representative from the EC, chair of the IWG on PMP, introduced GRPE-80-28, presenting a status report of the activities of the IWG on PMP since the last session of GRPE. The Chair requested more information on the new provision to measure sub-23 nm particulates and if those new provisions expected to be submitted as a working document for the next session of GRPE in June 2020 would be submitted as amendments to both UN GTR No. 15 and UN Regulation No. [XXX] on WLTP. The representative from EC clarified this was still being considered where those new provisions would be implemented.

44. Regarding tyre wear emissions, the representative from Russia asked whether the different types of tyres tested meant difference in purpose (summer versus winter tyres) and / or different brands. The Chair of the IWG on PMP clarified the focus was on different abrasion rates, and on particulate size distribution, as the correlation between abrasion rates, particulates number and particulate size is not linear and still needed to be further defined.

45. The representative from India required more information on the cut-off point to have effective 10 nm particulate size measurements, especially for natural gas vehicles, which in India, had peak particulate emission at around 10nm. He also wondered about any potential impact of sampling point position on PN measurement. The Chair of the IWG on PMP said the cut-off was to be set at around 7nm where a 50% efficiency had been measured. He said lowering this threshold implied high levels of artefacts measurements. For natural gas vehicles, further investigation were necessary to measure particulates below 10 nm with good efficiencies. He finally highlighted that there are three research programs going on under the H2020 funding scheme of the EU that might bring new information and confirmed that at this stage no impact had been noted on the sampling point location.

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

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

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