22. Following an explanation of the amendment needed for the transposition of Euro 6 requirements into UN Regulations (GRPE-65-22-Rev.1), the expert from the EC introduced GRPE-65-07, GRPE-65-08 and GRPE-65-09, containing three informal amendment proposals for UN Regulations Nos. 83, 101 and 103, respectively.

23. The expert from Germany underlined the need to take into account all recent changes in the regulatory texts and offered to contribute with written amendments to the existing drafts. The expert from OICA suggested having the possibility to revise the current draft in a meeting with all interested stakeholders.

24. GRPE encouraged interested stakeholders to contact the expert from the EC before 8 February 2013 to agree on a process allowing the submission of updated versions of GRPE-65-07, GRPE-65-08 and GRPE-65-09 as official documents for the June 2013 session, also taking into account the amendments from Germany.

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.
