Discussion paper concerning the transposition of GTR 15 into a UN Regulation. The paper raises two possible routes: 1) a UN Regulation identical to EU legislation but that would not be not applied (in its entirety as a distinct rule) outside the EU; 2) a “hierarchical” UN Regulation that combines all elements of all emissions thresholds at their most stringent level with lower levels of approval corresponding to regional/national requirements. The EC proposes option 2 as this would allow for a global rule where Contracting Parties could certify systems to standards outside their markets (e.g., Japan could issue approvals to EU standards and vice versa) under the UN Regulation.

Report of the WLTP Transposition Task Force

European Commission report on the effort to transpose the GTR on light vehicle emissions into UN type approval regulations, including handling of current UN Regulations on emissions (notably, UN R83 and UN R101) and process for implementing the WLTP requirements.

Discussion document considering approaches for the transposition of GTR No. 15 into a type-approval regulation appropriate for EU application.

EC input on options for test vehicle selection and Type 4 test (evaporative emissions).

Proposal to correct errors and clarify provisions in the draft UN Regulation on WLTP.

Proposal to correct errors and clarify provisions of the draft 01 series of amendments to the draft UN Regulation on WLTP.

Proposal with EC and Japan input.

Proposal to correct errors in the text and to clarify provisions based on Amendment 6 to UN GTR No. 15.

Proposal to correct errors in the text and to clarify provisions based on Amendment 6 to UN GTR No. 15.

Proposal to correct errors and clarify provisions based on requirements introduced in the Amendment 6 to UN GTR No. 15.

Proposal to correct errors and clarify provisions based on requirements introduced in the Amendment 6 to UN GTR No. 15.

Clarifications regarding “coasting” and twin roller dynamometers in 4WD operation.

Proposal to address use of the phrase “if PN measurement is required” throughout the regulation given that PN measurement in both Level 1A and Level 1B is now required.

Proposal to modify provisions of the 01 series pursuant to consideration of the proposal to address the use of the phrase “if PN measurement is required” in the original text of the regulation.

Proposal to introduce particle number requirements and limits for Level 1B. The proposal also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 and other adaptations to technical progress.

Proposal to ensure that Level 2 is the latest version of this Regulation and is therefore subject to mutual recognition under the 1958 Agreement, given that there is a concurrent proposal to for an 02 series of amendments which introduces particle number requirements and limits for Level 1B. This proposal for a 03 series of amendments also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 as well as other adaptations to technical progress.

This proposal introduces the new Utility Factor (UF) approach proposed in the Euro 6e emissions type-approval legislation. In addition, as a result of the application of the new tyre labelling Regulation (EU) 2020/7401, this proposal introduces a revised format of the table with tyre energy efficiency classes according to rolling resistance coefficients (RRC), in-line with the format proposed in the Euro 6e emissions type-approval legislation.

Annex to GRPE 92-08

Proposal to harmonise and consolidate the regional procedures and limits, update the provisions to align with Euro 7 requirements, including new particle number (PN10) provisions, a new SHED limit for evaporative emissions, updated On-board Fuel Consumption Monitoring provisions, new annexes with requirements relating to in-vehicle battery durability and a new test for range of Pure Electric Vehicles at low temperatures. An informal document amending this proposal is under development.

Proposal to introduce provisions relating to

• Manipulation Devices and Strategies that were previously in the 09 series of amendments to UN R83,
• the levels to which certain provisions apply,
• clarifications and corrections to the requirements for the laboratory test for pure electric range ratio at low temperature for Pure Electric Vehicles
• an update to allow the use in Levels 1A and 2 of actual tyre rolling resistance values to calculate the final road load coefficient for the individual vehicles, and
• align the Regulation with the current regional status and the current state-of-the-art.
