OICA proposes that Roadmap Items 2, 2bis, 3, and 4 be withdrawn or deferred until relevant international standardization bodies publish validated methodologies. OICA opposes radiated emissions requirements below 30 MHz in driving and charging modes, radiated emissions in the 16 GHz range, and variable driving conditions assessments, citing lack of technical rationale, absence of published international standards, poor reproducibility for large vehicle categories M3 and N3, and inconsistency with WP.29/2024/39 reproducibility standards. New R10.08 work items must demonstrably enhance safety, align with published international standards, and maintain regulatory stability per ECE/TRANS/WP.29/1044/Rev.3 and WP.29-196-07, WP.29-196-26, and ECE/TRANS/WP.29/1182.
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.
This document proposes a new Mutual Resolution No. 5 concerning Automotive Life Cycle Assessment. The use stage section (6.3) establishes methodology for calculating greenhouse gas emissions and energy consumption during vehicle operation across various levels, considering system boundaries encompassing tank-to-wheel and well-to-tank impacts, plus maintenance and consumables. Service life values are defined regionally based on average vehicle age at recycling. Energy consumption utilizes regional certification protocols adjusted by discrepancy and deterioration factors. The methodology addresses leakages including hydrogen and methane emissions, maintenance of consumables and parts with specified frequencies, and excludes major powertrain component replacement by default unless justified.
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.
