| Particle Measurement Programme: Minutes of the 57th (October 2026) session |
| Reference Number: PMP-57-12 |
|
Minutes of a PMP hybrid session held 12 October 2026 at the Palais des Nations in Geneva. Discussion covered amendments to GTR 24 and UN R179 on heavy-duty brake emissions, including new limits for 2030, C-factor measurements, driving modes, brake functions, emission factor calculations, and compliance and conformity of production procedures. Topics included measurement setup, payload factor, test inertia determination methods, inter-laboratory study status with data from 5 labs, and removal of square brackets from GTR text. The group reviewed brake particle emission work from Phase 2 of the DfT programme and preliminary results from a calibration materials inter-laboratory exercise involving 8 labs, recommending continued use of emery oil for annual validation at 23 nm. |

| Artificial Intelligence: General comments for drafting approach for the Baseline Document |
| Reference Number: AI-12-27 |
|
General guidance for drafting the baseline document on artificial intelligence in the automotive sector. The document emphasizes focusing revision on green text in AI-11-03, using change requests for substantive modifications processed during IWG plenary sessions, and integrating successful requests into a single master document. Four sections are addressed: Introduction (AAPC lead) to clarify purpose and scope; AI Uses & Benefits (OICA/CLEPA lead) to provide intuitive understanding and define terms; Risks (modifications by change request); and Risk Management (China and EME leads) to clarify operationalization in certification regimes while maintaining agreement-neutral, conceptual language at reference document level, avoiding prescriptive guidance. |

| Artificial Intelligence: Report of the 11th (September 2026) session |
| Reference Number: AI-12-02/Rev.1 |
|
Report of the 11th session of the IWG on AI held on 2 September 2026 online. The session discussed the status of the draft reference document, with the USA formally objecting to the refresh plan (AI-11-03, AI-10-04) and insisting that AI-09-06/Rev.3 presented to WP.29 was the only valid baseline document. The co-chairs and majority of experts, including the UK, Germany, France, Canada, the Netherlands, EU Commission, OICA/CLEPA, and SAE, supported using AI-11-03 as the baseline. The group decided to establish two small drafting groups to address green text in sections 2 and 4, with changes submitted through change request forms for review during plenary sessions. |
