29. The representative from OICA introduced GRPE-89-15. The representative from the European Commission agreed with most of the content of the proposal, showed some reservation on amending the definition of “vehicle type”, and made a suggestion on the proposal to amend para. 3.3. He finally sought some clarifications about the timing of the proposal and its potential adoption by WP.29 at its June 2023 session.

30. The Chair clarified slight editorial modifications would be possible at the June 2023 session of WP.29 and asked whether this proposal could be formally considered by GRPE at its next session.

31. The representative of OICA clarified OICA was expected to develop a formal proposal for the next session of GRPE. He explained that the existing definition of vehicle type might lead to some inconsistencies between interpolation family and inertia classes. The GRPE confirmed that a proposal on vehicle type will be discussed in the next GRPE session.

30. The representative from the European Commission introduced ECE/TRANS/WP.29/GRPE/2023/2, GRPE-87-26-Rev.1 and GRPE-87-43 related to the new 08 series of amendments to UN regulation No. 83. With this new series of amendments it will be equivalent to the European emission level Euro 6e. The representative from OICA introduced GRPE-87-10 and requested additional time to scrutinize GRPE-87-26-Rev.1. The representative from the UK highlighted the importance of this proposal for their regulatory framework and hoped for a final proposal to be adopted during this session of GRPE.

32. The representative from the Clean Air Association introduced GRPE-87-25. The Chair wondered why the representative from CAA did not propose to amend UN regulation No. 154, as the definition of defeat devices was moved there to avoid duplication. The representative from CAA stipulated they initially focus their effort on UN Regulation No. 83. The representative from OICA concurred with the Chair that the definition had been removed from UN Regulation No. 83 to have it in UN regulation No. 154.

33. The representative from the EC confirmed the intention was to make UN Regulation No. 83 as tight as possible, and said that given national litigation still on-going, the European Commission had no mandate to amend this definition. The Chair agreed the timing to make this proposal does not fit some national circumstances.

34. The representative from CAA said the intention of this proposal was to address contracting parties outside of the EU in the spirit of harmonization. GRPE rejected the proposal from the representative from the CAA.

35. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/2 as amended by GRPE-87-26-Rev.1, as reflected in Addendum 1, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2023 sessions as draft new 08 Series of Amendments to UN Regulation No. 83.
