23. The expert from EC presented ECE/TRANS/WP.29/GRPE/2016/3 proposing amendments to GTR No. 15 as a result of Phase 1B activities of the IWG on WLTP. He provided some background information on Phase 1A and on the main objectives of Phase 1B. He explained the technical topics addressed by ECE/TRANS/WP.29/GRPE/2016/3 with regard to conventional Internal Combustion Engine (ICE) vehicles, electrified vehicles, alternative pollutants and other improvements of the provisions of GTR No. 15.

24. The expert from OICA presented GRPE-72-09-Rev.2 introducing editorial corrections and improvements to the text of ECE/TRANS/WP.29/GRPE/2016/3 that had been identified since the last IWG meeting held in Tokyo in late September 2015. He mentioned that OICA accepted the task to collect and to consolidate all amendments to ECE/TRANS/WP.29/GRPE/2016/3 since the drafting coordinator could not be funded any longer by the Contracting Parties. He introduced GRPE-72-10-Rev.2 as a consolidated version of ECE/TRANS/WP.29/GRPE/2016/3 including all the modifications laid out in GRPE-72-09-Rev.2.
