39. The representative from the EC introduced ECE/TRANS/WP.29/GRPE/2023/3. This document is submitted by the experts of Japan and the European Commission. The text contains changes introduced into European legislation (Euro 6e) since the adoption of the previous version of the draft UN Regulation on RDE prepared by GRPE at its eighty-first session (ECE/TRANS/WP.29/GRPE/81/Add.2 and ECE/TRANS/WP.29/2020/120). The representative from OICA introduced GRPE-87-08 and GRPE-87-09. The representative from Japan supported ECE/TRANS/WP.29/GRPE/2023/3 and GRPE-87-08. The representative from the European Commission had some objections to some elements included in GRPE-87-08 and sought further clarification to make sure over-regulation is not included in the proposal, as might be the case where requiring not to perform RDE trips in reverse gear.

41. The representative from the European Commission did not support GRPE-87-09, requesting to try and avoid repeat the sub-optimal situation that led to last resort decision in other GRPE legislation and confirmed the European Commission had no mandate to agree on the inclusion of 2 levels in UN Regulation on Global RDE. The representative from Italy understood the intention of the OICA’s proposal, and was open to OICA’s proposal in the spirit of harmonization that is operational.

32. The representative of Australia introduced GRPE-89-22. The representative of OICA emphasized the proposed UN Regulation on RDE did not offer the possibility to choose an equivalent to Euro 6d levels and referred to a proposal raised in previous sessions of GRPE (GRPE-87-09) to include levels in UN Regulation on RDE.

He further mentioned there was no immediate solution to provide a regulatory package equivalent to Euro 6d levels.

35. The representative of Australia understood the complexity of developing the desired solution for the country and hoped a solution could be found in the near future.
