The presentation by the experts from UTAC/CERAM on the introduction of comprehensive, simple rating information to consumers, fleet operators and other stakeholders

72. The representative from UTAC/CERAM introduced GRPE-82-31-Rev-1 on the European Green NCAP and associated Green Vehicle Index (GVI) programs. The Chair requested the consortium to come back to GRPE when more results would be available. The representative from UTAC/CERAM confirmed more results would available in the coming months and another update could be envisaged when GRPE wishes to do so.

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.

68. The representative from OICA introduced GRPE-82-16 on potential issues that might arise on the applicability and interlinkages between UN Regulations Nos. 83, 154 and [XXX] on RDE. The representative from EC thanked OICA for raising the issue and reiterated their intention to address the issues and how to deal with in-service conformity test in the various documents. She welcomed and encouraged the implication and assistance from all stakeholders to find a clever way to propose a solution to GRPE by the next session of GRPE.

2. Mr. Rijnders, Chair of GRPE, opened the meeting, held as hybrid session, with all participants attending virtually because of the sanitary situation, and welcomed the participants. GRPE adopted the provisional agenda of the eighty-second session (ECE/TRANS/WP.29/GRPE/2021/1), as updated and consolidated in GRPE-82-02-Rev.2, and GRPE-82-03-Rev.2 as a tentative running order. GRPE took note of GRPE-82-01-Rev.1 on the organization of GRPE Informal Working Group (IWG) meetings held during the weeks prior to this meeting.

Proposal suggests that 2 new series of amendments are necessary: 83.08 to cover ISC for the WLTP Test and 83.09 to add ISC for the new UNR „RDE“ (which also has no ISC requirements) because Contracting Parties should be free to apply UNR 154 and UNR "RDE“, each with or without ISC without connection
A Contracting Party applying UNR 154 and UNR 83.08 but not UNR "RDE“ would be obliged to conduct or at least monitor RDE ISC in the absence of 83.09

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.

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.
