22. Having introduced ECE/TRANS/WP.29/GRPE/2013/11, containing a proposal for the transposition of the Euro 6 legislation on the exhaust emissions of pollutants into the UN Regulation No. 83 (as explained also in GRPE-66-22), the expert from the EC explained that further amendments to the Euro 6 regulations are expected to be agreed upon in July 2013. The original plan was to include these amendments in UN Regulation No. 83 with the adoption of ECE/TRANS/WP.29/GRPE/2013/11 (as amended by GRPE-66-04-Rev.1, concerning the choice of tyres) during the current GRPE session, and to submit the changes that will be agreed upon in July 2013 to the January 2014 session of GRPE.

23. The expert from OICA suggested postponing the approval of ECE/TRANS/WP.29/GRPE/2013/11 (and related modifications, including those contained in GRPE-66-32, concerning requirements for daytime running lamps and clerical errors) due to the potential confusion caused by the forthcoming amendments to the Euro 6 regulatory texts.

24. The experts from Germany and the Netherlands supported the approach suggested by OICA. The expert from Germany also stated that the Euro 6 requirements concerning vehicles using a mixture of hydrogen and natural gas as fuel shall follow the introduction of safety-related requirements. The expert from the EC clarified that, in the European Union, setting the emission requirements does not lead to the possibility to type approve the whole vehicle, since this will only be feasible once the safety provisions are defined and adopted. Following the warning of the expert from OICA about the absence of whole vehicle type approval requirements in the UN regulatory framework, he added that, if deemed necessary, the introduction of emission requirements for vehicles using a mixture of hydrogen and natural gas as fuel in UN Regulation No. 83 could be reconsidered.

25. GRPE agreed that all modifications introduced in the current session of GRPE to ECE/TRANS/WP.29/GRPE/2013/11, as well as those emerging from the discussion scheduled for July 2013 in the European Union framework and other eventual changes, shall be incorporated in a new working document that will be submitted for the January 2014 session of GRPE.

26. The expert from OICA introduced GRPE-66-16, containing a proposal to amend the 06 series of amendments to UN Regulation No. 83 in order to align the emission requirements for social needs vehicles (currently based on M vehicles) with those enforced in the European Union (also contemplating N1, class 3 limits).

27. GRPE requested the secretariat to distribute GRPE-66-16 as an official document for consideration at the GRPE session of January 2014.

28. Presenting GRPE-66-22, the expert from the EC explained that the implementation of the Euro 6 legislation also justifies the proposals (contained in ECE/TRANS/WP.29/GRPE/2013/9 and ECE/TRANS/WP.29/GRPE/2013/10, respectively) to amend UN Regulations Nos. 101 and 103.

29. The expert from OICA introduced GRPE-66-17, explaining that it contains modifications to ECE/TRANS/WP.29/GRPE/2013/9 and additional amendments to the 01 series of amendments to UN Regulation No. 101 regarding the requirement for daytime running lamps and the fuel consumption of fuel cell vehicles.

30. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/9, as amended by GRPE-66-17, and ECE/TRANS/WP.29/GRPE/2013/10, not amended. GRPE requested the secretariat to submit the adopted proposals to WP.29 and AC.1, for consideration at their November 2013 sessions, respectively as Supplement 3 to the 01 series of amendments to Regulation No. 101 and Supplement 4 to the 00 series of amendments to Regulation No. 103.
