Agenda Item 18.7.
UN GTR No. 15 (Worldwide harmonized Light vehicle Test Procedures (WLTP) – Phase 2)

157. The representative of the European Union, as technical sponsor, informed AC.3 that Amendment 4 of UN GTR No. 15 had been finalized during the seventy-sixth GRPE session in January 2018. He announced that GRPE recommended to AC.3 the adoption of this Amendment 4 at its June 2018 session.

158. He added that the work of the IWG focused, at this stage, on the transposition of UN GTR No. 15 to a new UN Regulation annexed to the 1958 Agreement. He reported that a Task Force dealing with so called “new issues” had been created to work on In Service Conformity, Conformity of Production and durability. Other tasks, such as On Board Diagnostics and low temperature tests and electrified vehicles were planned for the 2019/20 time horizon.

159. The representative of the European Union presented WP.29-174-09, proposing a work item called Global Real Driving Emissions (RDE). He proposed that the existing RDE European legislation would be included in the Compendium of candidates. He also proposed the creation of an IWG on RDE and to discuss organizational details at the June 2018 session of GRPE. AC.3 invited the representative of the European Union to prepare an official proposal for formal adoption at the June 2018 session.

160. The representative of Japan, Co-Chair of the IWG on WLTP, mentioned the Japanese plan for RDE as presented during the last GRPE session of January 2018 (GRPE-76-18). He added that the legal text was expected to be published in March 2018 with a potential entry into force in October 2022.

161. He presented WP.29-174-17 proposing amendments to WP.29-174-09. He suggested that Japan could co-sponsor such activities.

162. The representative of Germany welcomed the initiative to work on the global harmonization of RDE. He wondered whether the RDE provision should be inserted in UN GTR No. 15 or in a new UN GTR.

163. The representative of the Republic of Korea also welcomed the initiative to work on RDE at the World Forum. He announced that his country would be willing to co-sponsor this work, involving its Ministry of Environment.

164. The representative of the Netherlands, Chair of GRPE, also welcomed the initiative to work on RDE at the World Forum. He invited all CPs to support the harmonization of RDE provisions with flexible positions, for example on the boundary conditions of the test. He suggested that contracting parties consider the possibility to include harmonized RDE provisions in a new GTR.
