A-LCA IWG plans to submit a Working Document by 22nd July 2026 containing only items agreed by the entire IWG, with non-agreed items on CoC, Electricity Modeling, and Battery Replacement handled under one of three options: Option 1 creates a memorandum within the working document for non-agreement items; Option 2 submits a separate Informal Document titled Interim Guidance for A-LCA to help practitioners with CFP calculation; Option 3 similarly submits an Informal Document produced by A-LCA IWG during 95th GRPE in October, with both options reserving non-agreement items in the Working Document as discussion-starters for future work.
The 41st IWG on A-LCA session (26 May 2026) discussed the document package for submission to GRPE. Japan presented approaches for handling unresolved sections through working documents and supplementary explanatory material. The United States proposed including only consensus text in working documents. No final decision was taken. The group continued review of Table 1, Chain of Custody, Electricity and Energy Modelling, OVC-HEV and FCV methodology, and battery and major powertrain component replacement, with no agreement reached on these topics. The 42nd session is scheduled for 15 June 2026 and the 43rd for the week of 6 July 2026.
Proposal to establish Chain of Custody provisions for Automotive Life Cycle Assessment specifying five models—Identity Preserved, Segregation, Controlled Blending, Mass Balance, and Book and Claim—representing standardized approaches for collecting and managing company-specific information across supply chain settings. The Book and Claim model shall not be used. Government authorities reserve rights to define implementation rules specifying how Chain of Custody approaches are applied, based on alignment with global standards such as ISO and the GHG Protocol and the upcoming revision of the EF Recommendation (2279/2021). Minimum requirements shall be established for Mass Balance application to prevent diverse interpretations and misuse.
The IWG on A-LCA will discuss agreement on a document package to be submitted to GRPE, review the latest CoC covering general aspects including pre-consumer scrap, electricity/energy modeling, and OVC-HEV/FCV and battery/powertrain replacement, and determine next steps.
This baseline draft for UN R48 (10 series of amendments) establishes uniform provisions for vehicle lighting and light-signalling device installation. The document reflects all modifications agreed at GRE-94 and incorporates an updated proposal from IEC regarding technological neutrality for LS devices. Key additions include provisions for work lamps to be included after formal WP.29 adoption in June 2026, updated tables for positioning and geometric visibility angles (Annexes 18–19), and revised terminology replacing “dipped-beam/main-beam” with “passing-beam/driving-beam” throughout. Open points address apparent surface visibility against stop lamps and consistency with IWVTA transitional provisions, with transitional provisions for the 10 series specifying acceptance dates and phase-in periods to be finalized.
Proposal to amend para. 3.5.3.1. to delete reference to colour verification of retro-reflecting optical units, amend para. 5.1.2. to reduce required samples from ten to eight, amend para. 5.1.3.1. to reduce samples from ten to eight and divide remaining six samples into three groups of two, insert para. 5.1.3.1.1. specifying Classes IA, IB, IIIA and IIIB, amend para. 5.1.7. to delete sample columns i and j from Tables 4 and 5 and delete the weathering resistance test row, and amend reference to Part 4 of Annex 6 to Part 5 of Annex 6 in both tables.
Proposal to amend UN R86 on approval markings and testing requirements:
128. AC.3 agreed to consider this item at its March 2011 session.
