Updated text for the use stage of the proposed Mutual Resolution No. 5 concerning Automotive Life Cycle Assessment (A-LCA) addressing use stage methodology, including system boundaries encompassing in-use energy consumption and GHG emissions covering well-to-tank and tank-to-wheel impacts, maintenance and consumables impacts, and leakages; defining service life values by contracting parties based on official data on vehicle age at recycling; establishing level concepts for selecting regional certification energy consumption values and determining discrepancy and deterioration factors to represent real-world performance; specifying methodologies for calculating in-use energy consumption for vehicles with single and dual-mode powertrains including off-vehicle charging hybrid electric vehicles; addressing methane, hydrogen, and fluorocarbon emissions; providing maintenance scope including consumables and maintenance parts with associated frequency determination; excluding replacement of major powertrain components by default unless justified; and requiring collection of specified activity data and GHG emission factors. Full text of the draft MR5 previously submitted as GRPE/2026/2.
Proposal to amend para. 6.3.1. to clarify use stage system boundaries, revise para. 6.3.2.1. regarding service life methodology and regional adaptation, delete and rewrite para. 6.3.3. on use stage consumption to introduce level concepts for certification values and restructure discrepancy and deterioration factor determination, reserve sections on vehicles with dual-mode powertrains and fuel cell and OVC-HEV deterioration calculations pending further development, amend para. 6.3.3.2.2.2. addressing OVC-HEV battery degradation (reserved), add para. 6.3.6.7. on swappable parts (reserved), and update Table 14 to include parts and/or components defined by vehicle manufacturer as mandatory for Level 3/Level 4 assessments, supported by GRPE/2026/2.
Proposal to delete paras. 15.1.2. and 15.1.3., renumber para. 15.1.4. as 15.1.2., and amend the renumbered para. 15.1.2. to provide that as from 36 months after the official date of entry into force of the 06 series of amendments, Contracting Parties applying this Regulation may prohibit the sale of helmets and visors which do not meet the requirements of the 06 series of amendments. The proposal is based on informal document GRSP-78-44 and permits Contracting Parties to issue approvals according to the 05 series of amendments, which aligns with Revision 3 of the 1958 Agreement.
Proposal to amend para. 2.27. to redefine “ISOFIX position” as a position satisfying UN R145 requirements to allow installation of ISOFIX child restraint systems as defined in UN R44 and UN R129, amend para. 2.36. to redefine “i-Size seating position” as a position satisfying UN R145 requirements to allow installation of i-Size child restraint systems as defined in UN R129, insert new para. 2.48. defining “Minimum effective seat belt length” as a portion of seat belt webbing usable to restrain an occupant, insert new para. 5.1.11. specifying minimum effective seat belt lengths of at least 2040 mm for 3-point seat belts and 1200 mm for 2-point seat belts in vehicles of categories M2 and M3, amend para. 5.2.1. to establish seating position requirements for various child restraint system types by vehicle category, amend para. 5.2.2. to delete reference to manufacturer recommendations, amend para. 5.3.5. to limit information requirements to category M1 vehicles, insert new para. 11.3. establishing transitional provisions with entry into force of the 02 series of amendments on the official date and mandatory non-acceptance of earlier series approvals issued after 1 September 2030, delete para. 1.2. of Annex 6 Appendix 2, and insert new Annex 8 specifying measurement procedure for minimum effective seat belt length.
Proposal to amend para. 2.9. to define “ISOFIX position” as one that satisfies requirements of this Regulation to allow installation of ISOFIX child restraint systems as defined in UN R44 and UN R129, amend para. 2.24. to define “i-Size seating position” as one that satisfies requirements of this Regulation to allow installation of i-Size child restraint systems as defined in UN Regulation No. 129, amend para. 5.2.2.7. to exclude low ISOFIX anchorages installed in vehicles of category M₂ or M₃ from certain requirements, amend para. 5.2.4.1. to exclude vehicles of category M₂ and M₃ from marking requirements, and amend para. 6.2.5.1. to establish differentiated seat inertia forces for vehicles of categories M₂, N₂, M₃, and N₃. The justification clarifies that the definitions are based on tests fulfilled in this Regulation regarding strength rather than CRS category, addresses that the prior ISOFIX position definition incorrectly allowed i-Size CRS installation in non-i-Size positions, and harmonizes inertia loads for M₂ and M₃ vehicles with UN R14.
