82. The representative of Japan, Chair of the IWG on IWVTA presented a proposal for the 04 series of amendments to UN Regulation No. 0 (WP.29-184-07), the regular annual update of the UN Regulation and its Annex 4, Part A, Section I (List of requirements for Universal (U)-IWVTA), including an addition of four UN Regulations into the table (Nos. 154, 161, 162 and 163). He invited the World Forum to consider the document for issuing as an official proposal for its November 2021 session.

83. The representative from Switzerland explained the situation in the country that is similar to the situation in the EU, where approval from UN Regulation No. 154 are not sufficient to grant vehicle emission approvals. He suggested to add a footnote in UN Regulation No. 154 to clarify the situation for all CPs. The representative from the EU agreed that for the purpose of EU type approval, an approval to UN Regulation No. 154 needs to be accompanied by supplementary evidence of meeting regional regulatory requirements. He added that the intention of the EU was not to prevent other CPs to benefit from an inclusion of UN Regulation No. 154 into UN Regulation No. 0.

84. The representative from OICA sought further clarifications from the EU, and whether approvals to UN Regulation No. 154 (accompanied by the needed additional EU regulatory requirements) would be accepted by the EU. The representative from the EU said the questions would be clarified in the EU legislation and stated the approvals to UN Regulation No. 154 in itself would be accepted, but evidence related to additional emission requirements not covered by UN Regulation No. 154 was needed to get EU Whole Vehicle Type approval. The representative from the UK supported the contribution from Switzerland and suggested some further discussions were needed. The Chair invited WP.29 to reconsider this issue during the November 2021 session, if need be, when the inclusion of UN Regulation No. 154 into UN Regulation No. 0 is expected.

85. The World Forum requested the secretariat to issue WP.29-184-07 as an official document for consideration at its November 2021 session, invited interested stakeholders to discuss outstanding issues and to revise the proposal accordingly prior to submission.
