12. The representative from EC, drafting coordinator for WLTP activities, introduced ECE/TRANS/WP.29/GRPE/2020/14, as amended by GRPE-81-14, as draft Amendment 6 to UN GTR No. 15, together with its technical report (GRPE-81-15). The Chair from the IWG on Particulate Measurement Protocol (PMP) also presented GRPE-81-10 introducing revisions also to be included in ECE/TRANS/WP.29/GRPE/2020/14 as part of Amendment 6 to UN GTR No. 15 on a supplementary methodology to measure sub-23nm particulates. The Chair of the IWG on PMP also introduced GRPE-81-11 providing explanatory note on the sub-23nm procedure part of Amendment 6 to UN GTR No. 15. He also informed GRPE that GRPE-81-11 had been included in the technical report of Amendment 6 to UN GTR No. 15 (GRPE-81-11 is included in GRPE-81-15).

13. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/14, GRPE-81-14 and GRPE-81-10 as amended by Addendum 1 to this chair’s notes. GRPE also adopted the technical report (GRPE-81-15) as reproduced in Annex V. GRPE requested the secretariat to submit Addendum 1 and Annex V to WP.29 and Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their November 2020 sessions as draft Amendment 6 to UN GTR No. 15.

14. The Chair of the IWG on WLTP presented GRPE-81-20-Rev.1. highlighting the latest activities of the IWG. He concluded by stating that the IWG mandate was expiring in June 2020 and no Contracting Parties had the resources to become the main sponsor to carry on with the activities. He suggested WLTP-related activities that still require further work, if any, would be developed by interested parties on an ad-hoc basis and be submitted to GRPE for its consideration. The representatives from the EC, the United Kingdom of Great Britain and Northern Island (UK) and of the United States of America showed their support for such approach and confirmed their willingness to be involved to ad-hoc discussions should the need arise.

15. The Chair of GRPE thanked the IWG on WLTP for the tremendous achievements over the last 15 years and reckoned WLTP is an acronym well-known all over the world, not only by expert involved in WP.29 activities. He regretted a proper farewell to the WLTP family could not be done in person, and offered, if possible, to have a physical event during the next session of GRPE in January 2021. GRPE shared the congratulations to the IWG and praised the achievements of the group.

16. GRPE noted the request for a meeting room for half a day during the GRPE week in January 2021 for the ad-hoc group looking at WLTP-related issues.
