The IWG on Automotive Life Cycle Assessment reviewed open issues in the working document, focusing on bracketed text requiring resolution. Key outstanding items include primary data provisions, chain of custody, electricity modelling, use-phase emissions, PHEV provisions, and traction battery treatment. A colour-coded classification procedure was introduced for Contracting Parties to indicate positions on bracketed sections. Unresolved items will be deferred to Phase 2. Positions must be submitted by 28 February, with the next session on 5 March 2026.
