| Automotive Life Cycle Assessment: Minutes of the 36th (March 2026) session |
| Reference Number: A-LCA-36-06 |
|
The 36th session of the Automotive Life Cycle Assessment IWG reviewed progress on a harmonised global methodology. SG7 will consolidate all comments by 1 April 2026 for line-by-line IWG review. Key unresolved items include PHEV methodology, component replacement approaches, and electricity modelling. Industry emphasised the need for a single global methodology and technology neutrality. The United States noted insufficient definition of methodological aspects. The group agreed to prioritise technical issues first, then policy-related issues, with virtual sessions in April and May. A decision point is targeted for 19 June 2026, with possible adoption at the October GRPE session. The IWG mandate extends to December 2026. |

| Reference Number: PMP-56.2-02 |
|
The PMP session discussed revisions to the group’s terms of reference to address overlapping technical issues with GTR 24, UN R179, and replacement parts regulations. Three task forces were proposed: TF3a on layout and testing, TF3b on speed-limited vehicles, and TF4 on electromechanical brakes. Topics included non-original brake parts regulations, UN R179 amendments for new vehicle categories, and GTR heavy-duty brake particle emissions standards. The next meeting was scheduled for end of April 2026. |
