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.

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.

Working draft of notes concerning future activities to update the initial resolution on A-LCA.

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.

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.
