2. Mr. Rijnders, Chair of GRPE, opened the meeting, welcomed the participants and expressed the best wishes for the New Year. GRPE adopted the provisional agenda of the seventy-eighth session (ECE/TRANS/WP.29/GRPE/2019/1), as updated and consolidated in GRPE-78-11-Rev.3. GRPE took note of GRPE-78-01-Rev.1 on the organization of GRPE Informal Working Group (IWG) meetings held during the week.

6. The Secretary introduced GRPE-78-08 and reported on relevant items discussed during the 175th and 176th sessions of the World Forum for Harmonization of Vehicle Regulations (WP.29). He referred to ECE/TRANS/WP.29/1138 and ECE/TRANS/WP.29/1139 for further details.

Presentation raising concerns during the transition from NEDC to WLTP and proposing measures to facilitate this transition pending adoption of WLTP under the 1958 Agreement.

11. The expert from OICA introduced GRPE-78-20 proposing to amend UN Regulation No.101 to permit the measurement of fuel and energy consumption and CO2 emissions using road loads which are calculated according to the method used in EU correlation. The representative from EC sought clarifications on the use of CO2MPAS for this proposal. The representative from OICA explained that CO2MPAS formula are expected to be used for the calculation of road load coefficients, without using the CO2MPAS software itself. The representative from EC backed the proposal and requested that the EU JRC be involved in developing the working document. The Chair thanked the representative from OICA for initiating this effort and for making the latest legislative provisions available to all Contracting Parties.

Proposal to clarify the relationship between approval levels, reference fuels and PN limits for PI vehicles and to modify the calculation formulae for determination of evaporative emissions in accordance with changes already agreed in UN GTR No. 19.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2019/8 and GRPE-78-27 clarifying the relationship between approval levels, reference fuels and particulate number limits for positive ignition engines and to modify the calculation formulae for determining evaporative emissions in accordance with changes already agreed in UN GTR No. 19. He stated that GRPE-78-27 superseded GRPE-78-16 and GRPE-78-16 has therefore not been introduced. He stated that some amendments were about harmonizing national legislation and SAE standards. The Chair insisted that ISO or SAE standards should fit the needs of UN Regulations and not that UN Regulations should align with ISO/SAE standards. The representative from the EC opposed to the change on SCR provisions and accepted the other amendments proposed. The representative from the UK and EC sought clarifications on the use of characters to reflect emission levels. The experts from EC and UK proposed minor corrections to ECE/TRANS/WP.29/GRPE/2019/8 and GRPE-78-27 that GRPE adopted as reproduced in Annex IV to the session report.

10. GRPE requested the secretariat to submit Annexes IV and VI of the report to WP.29 and Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2019 sessions as draft Supplement 13 and 9 to the 06 and 07 series of amendments to UN Regulation No. 83 respectively. GRPE also requested to submit Annex V of the report to WP.29 and AC.1 for consideration and vote at their June 2019 sessions as draft Corrigendum 1 to Supplement 8 to the 07 series of amendments to UN Regulation No. 83.

16. The expert from EC, leading the task force on the transposition of WLTP into a UN Regulation annexed to the 1958 Agreement, introduced GRPE-78-14-Rev.1 on the activities of his group. He reported on an alternative concept to transpose UN GTR No.15 into a UN Regulation to avoid disharmonization by including Level 1a (Europe) in the 08 series of amendment to UN Regulation No. 83. He detailed why the representatives from Japan objected to the proposal during a recent meeting of the task force.

17. He highlighted a request for the work on the transposition to be delayed by six months, with a draft working document to be proposed for the January 2020 session of GRPE. EC and Japan backed this request for a delay.

18. He also underlined the urgency of the task force to work on the definition of the most stringent, harmonized level (so called Level 2). The Chair recalled the need for harmonization of the legal provisions for mutual recognition at the most stringent level. He emphasized that harmonization should not force Contracting Parties to reduce their national level of stringency in emission performance.

19. The representative from EC agreed with the Chair on the need for harmonization and committed the EC to arrange meetings to solve the remaining issues. She also reminded the need to include Real Driving Emissions (RDE) provision within the 58 Agreement to be in line with the latest legislative developments in Europe.

20. The representative from Japan also agreed with the objective of harmonization.

21. The representative from OICA thanked the positive feedback from the chair, EC and Japan on reaching harmonization and reminded GRPE that harmonization had to be technically and economically feasible and insisted industry stakeholders remain available to be involved in any forthcoming discussions.

22. GRPE noted the request for a meeting room for one and half day during the GRPE week in May 2019.
