Draft letter intended for the UN Office of Legal Affairs to handle three planned series of amendments to the proposed UN Regulation transposing GTR 15 (WLTP) simultaneously. Normally, each series of amendments to a regulation must be implemented sequentially. In the case of WLTP, the informal group is proposing to use the series of amendment to implement stringency levels based upon regional needs (e.g., 00 series for the EU, the 01 series for Japan, and the 02 series as the most stringent set of requirements). The informal group is considering a request to handle this situation differently such that the 3 initial series would be implemented simultaneously, enabling future changes in regional stringency to proceed in a timely fashion (e.g., parallel development of new series based on regional objectives).
19. The expert from EC, leading the task force on the transposition of WLTP into the 1958 Agreement, GRPE-76-24 on the activities of his group with the development of three alternatives for the construction of a UN Regulation on WLTP, which were presented to the IWG on International Whole Vehicle Type Approval (IWVTA). He recalled the task force’s intention to proceed with a new series of amendments (08) of the existing Regulations Nos. 83 on emissions, including, e.g. Real Driving Emissions (RDE) and that would refer to the new UN Regulation on WLTP to gain approval for tests Types 1 and 4.
20. GRPE discussed the possible alternatives to structure the future UN Regulation on WLTP to address regional specificities. GRPE decided to request the secretariat to consult the Office of Legal Affairs (OLA) as noted in the Appendix of GRPE-76-24.
