20. The expert from EC explained the transposition process of the UN GTR on WLTP into the legislation of the European Union with the intention to replace in 2017 the New European Driving Cycle (NEDC) with a new European Regulation (GRPE-71-19-Rev.1). He continued his presentation on possible solutions to transpose the UN GTR on WLTP into a new UN Regulation to be annexed to the 1958 Agreement taking into account that limit values are not harmonized yet and that the options in UN GTR No. 15 shall also be transposed. He pointed out a multi-level option as a first step towards full harmonization and as best solution to enable Europe and Japan to issue approvals according to the 1958 Agreement. He explained that level 2 would contain the most stringent limits from across all regions and would be subject to full mutual recognition, whereas levels 1a (with current UN Regulation No. 83 limits) and 1b (with other limits such as the Japanese ones) would be subject to optional acceptance by other Contracting Parties.

23. The Chair of GRPE invited the group to review the multi-level solution introduced in GRPE-71-19-Rev.1 and to resume consideration at the next GRPE session in January 2016.
