The agenda includes discussion of Draft Resolution on Used Vehicles being submitted to WP.29 as document ECE/TRANS/WP.29/2026/10, anticipated comments on the Formal Document, discussion on the mandate and way forward following adoption of the resolution, dates of the next IWG, and any other business.
The Draft Resolution on Used Vehicles was discussed; Chapter 9 on Environment was updated to remove references to Euro levels and replace them with standard text linked to model year. Footnote 2 required clarification regarding regional requirements. Editorial proposals were reviewed and agreed. The Secretary would compare Chapter 9 with previous proposals, with comments requested by 8 April. Agreement was reached on text for the June WP29 meeting, with formal review at June meeting and adoption at November WP29 session. Editorial comments on transfer of information related to vehicles in transfer to low- and middle-income countries were reviewed and agreed.
OICA proposes that Roadmap Items 2, 2bis, 3, and 4 be withdrawn or deferred until relevant international standardization bodies publish validated methodologies.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.
