14. The GRPE Chair recalled that the WLTP UN GTR (ECE/TRANS/WP.29/2014/27) is scheduled to be considered by WP.29 in March 2014, jointly with the technical report on this activity (ECE/TRANS/WP.29/2014/28). He noted that the technical report is referencing the detailed reports on the activities of the WLTP subgroups on the Development of the Harmonized Cycle (DHC) and the Development of the Test Procedure (DTP) (GRPE-68-03 and GRPE-68-04). GRPE endorsed GRPE-68-03 and GRPE-68-04.

15. Speaking on behalf of the co-sponsors, the EC and Japan, the expert from the EC presented ECE/TRANS/WP.29/2014/30, containing a proposal to extend the mandate of the WLTP informal working group until November 2016 to develop a first amendment to the WLTP UN GTR. He outlined an indicative road map defining the development of these activities and explained that it foresees a longer period of work with respect to WP.29-161-14 and GRPE-67-06, respectively circulated at the November sessions of WP.29 and GRPE. GRPE endorsed ECE/TRANS/WP.29/2014/30.

Reference Number: WP.29/2014/30

Proposal for a further “phase 1b” in the development of the GTR on light vehicle emissions. In order to meet Contracting Party objectives, the draft GTR has been submitted for adoption by the Forum in March 2014. Although the current draft offers a complete test cycle, the WLTP experts want to improve the regulation by further addressing a number of technical elements that were set aside due to time and resource constraints.

16. The Chair of the WLTP introduced the status report of the group (GRPE-68-15). He explained that the Chair and the Drafting Coordinator are experts from the European Union, the Vice-Chair and a Technical Secretary are experts from Japan, and a second Technical Secretary representing OICA. He explained that the group is currently structured as a subgroup on E-Lab and task forces addressing emerging open issues. Having outlined parallel activities being carried out in the EU, he invited Contracting Parties to provide feedback on these subjects by mid-February 2014, in order to update the list of issues that need to be addressed by the WLTP group. He concluded informing GRPE about the next meetings of the group and requested the secretariat to reserve a room for a meeting to be held during the June 2014 GRPE session.
