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.

Proposal to update UN R49 to accommodate Automated Driving Systems (ADS). The supplement modifies definitions, mass calculations, warning systems, and testing procedures to apply to vehicles without human drivers. References to drivers are replaced with “vehicle user” terminology, and special provisions are added for ADS-equipped vehicles in testing and operational requirements.

This Supplement proposes to update UN R154 to accommodate vehicles fitted with Automated Driving Systems (ADS), specifically categories X and Y. Amendments include new definitions for ADS-related terms, modifications to testing procedures, and updated references to vehicle construction standards. Driver-related systems are renamed to account for vehicles without human drivers. Special provisions establish requirements for ADS road load determination and testing modes, while messaging systems are adapted to send signals to ADS instead of or in addition to driver notifications.

Proposal to amend document GRBP-83-32-Rev.1. Paragraph 1.2.9. amended to exclude special use Professional off-road tyres from scope. Paragraph 2.51. amended to read that the authority which has granted type approval may verify conformity control methods, with normal minimum frequency of verifications at least once every three years. Justification states special use tyres should be excluded as no limits will be established for them, and the three-year frequency aligns with Schedule 1 of the 1958 Agreement.

ETRTO comments on EC/JRC compromise proposal for Annex 4 tyre abrasion. ETRTO proposes an ALI range minimum of 0.5 as feasible and consistent with statistical distribution in MA results, rejecting the 0.7 range as unrealistic. For Generic Transfer Function gain, ETRTO recommends retaining a = 1.38 rather than the revised a = 1.45, to minimize rejection of good vehicle test results. ETRTO requests TFTA ToR amendment to confirm these conditions by February 2027 based on TA-45-9.
