WTPP has started post-processing activity for the 3PMSF cluster. 90% of test results for normal tyres are expected to be reached by June 2026. WTPP members are working on dataset correction including typos and rounding, and definition of the outliers.

GRVA reviewed the advance copy of ECE/TRANS/WP.29/2026/137 circulated in April 2026 and proposed modifications integrated in the final version in June 2026. The amendments replace [ADS], [This Regulation], [XXX], and [number of this Regulation] with [185]; amend Contents, paragraph references, and numbered paragraphs; add periods and remove brackets; renumber paragraphs 1.4.11.5, 1.4.11.5.1., and 1.4.11.5.2. as 1.4.12., 1.4.12.1., and 1.4.12.2.; replace square brackets with parentheses and examples in tables; and amend fallback requirements and data recording specifications.

The 20th ADS IWG and 17th GRVA Workshop on ADS convened in Bangkok from April 27 to May 1, 2026. OPIs consolidated draft text for the Guidance and Interpretation document (GID) on ADS, addressing DDT performance, application for approval, user interactions, SMS, ISMR, safety case, and assessment provisions. The GID would be submitted to GRVA in May and WP.29 in June as an informal document, then officially in September and November. Numerous amendment proposals were discussed, including clarifications on crash causation, priority vehicles, road safety agents, MRC requirements, remote assistance, and scenario testing. The next session in Brussels (July 14-17) aims to finalize the GID, with Phase 2 work items to be considered thereafter.

IWVTA, established in 2017 under UN R0 and the 1958 Agreement, extends mutual recognition from individual vehicle systems to whole vehicles, reducing duplication while preserving safety and environmental standards. Key benefits include simplified approval procedures, reduced testing and administrative costs, and improved time-to-market through a single coherent whole-vehicle approval framework based on UN Regulations. IWVTA acts as a convergence tool between different regulatory systems and offers a flexible framework for emerging markets. Main obstacles include that IWVTA is not yet global, with limited coverage, uneven acceptance, and complexity of introduction.

The agenda includes discussion of the workplan 2025–2026 for C1 tyres and test campaign status, preparation of the IWG WGWT status report to GRBP 84th session (September 2026), and identification of next meetings scheduled for 2 July and 15 July 2026.

The agenda includes discussion of Draft Resolution on Used Vehicles being submitted to WP.29 as document ECE/TRANS/WP.29/2026/10, anticipated comments on the Formal Document, discussion on the mandate and way forward following adoption of the resolution, dates of the next IWG, and any other business.

The Draft Resolution on Used Vehicles was discussed; Chapter 9 on Environment was updated to remove references to Euro levels and replace them with standard text linked to model year. Footnote 2 required clarification regarding regional requirements. Editorial proposals were reviewed and agreed. The Secretary would compare Chapter 9 with previous proposals, with comments requested by 8 April. Agreement was reached on text for the June WP29 meeting, with formal review at June meeting and adoption at November WP29 session. Editorial comments on transfer of information related to vehicles in transfer to low- and middle-income countries were reviewed and agreed.

OICA proposes that Roadmap Items 2, 2bis, 3, and 4 be withdrawn or deferred until relevant international standardization bodies publish validated methodologies. OICA opposes radiated emissions requirements below 30 MHz in driving and charging modes, radiated emissions in the 16 GHz range, and variable driving conditions assessments, citing lack of technical rationale, absence of published international standards, poor reproducibility for large vehicle categories M₃ and N₃, and inconsistency with WP.29/2024/39 reproducibility standards. New R10.08 work items must demonstrably enhance safety, align with published international standards, and maintain regulatory stability per ECE/TRANS/WP.29/1044/Rev.3 and WP.29-196-07, WP.29-196-26, and ECE/TRANS/WP.29/1182.

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.

The 41st IWG on A-LCA session (26 May 2026) discussed the document package for submission to GRPE. Japan presented approaches for handling unresolved sections through working documents and supplementary explanatory material. The United States proposed including only consensus text in working documents. No final decision was taken. The group continued review of Table 1, Chain of Custody, Electricity and Energy Modelling, OVC-HEV and FCV methodology, and battery and major powertrain component replacement, with no agreement reached on these topics. The 42nd session is scheduled for 15 June 2026 and the 43rd for the week of 6 July 2026.

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.

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.

The agenda addresses correction of errors and omissions in UN Regulation 150-01, including a consolidated proposal merging GRE-92-18, GRE-94-02/Rev.1, GRE-94-11, and GRE-94-24, and a decision on addition of Part 7 on Colour-fastness to Annex 6. Baseline documents for UN Regulations Nos. 48, 53, 74, and 86 will be reviewed, along with transitional provisions. The group will consider visibility of direction indicators and Korean concerns regarding rear direction indicator lamp height. The 79th meeting is scheduled for Tokyo in September 2026.

This baseline draft for UN R48 (10 series of amendments) establishes uniform provisions for vehicle lighting and light-signalling device installation. The document reflects all modifications agreed at GRE-94 and incorporates an updated proposal from IEC regarding technological neutrality for LS devices. Key additions include provisions for work lamps to be included after formal WP.29 adoption in June 2026, updated tables for positioning and geometric visibility angles (Annexes 18–19), and revised terminology replacing “dipped-beam/main-beam” with “passing-beam/driving-beam” throughout. Open points address apparent surface visibility against stop lamps and consistency with IWVTA transitional provisions, with transitional provisions for the 10 series specifying acceptance dates and phase-in periods to be finalized.

Cooperative intelligent transport systems (C-ITS) enable ITS users to interact and cooperate by exchanging secured and trusted messages without prior knowledge of each other and in a non-discriminatory manner. The EU C-ITS security credential management system has three central roles that the Commission shall be responsible for ensuring are executed. Priority area IV is dedicated to ITS services for Connected and Automated Mobility (CCAM). Work on specifications under the ITS Directive will restart in 2026, covering the EU C-ITS security credential management system, harmonised C-ITS services, and fostering development and implementation of C-ITS. Currently, 2.5 million vehicles are sold and 20,000 km of roads are equipped with C-ITS, with 100,000 km covered by C-ITS services across more than 50 European cities in 21 European countries.

Based on SLR-73-07/Rev.1 including LUPC-01-03, this consolidated and amended text of UN R48 defines uniform provisions for vehicle lighting and light-signalling device installation. The regulation establishes requirements for vehicles of categories M₁–M₃, N₁–N₃, and O₁–O₄ regarding lamp presence, positioning, geometric visibility, orientation, electrical connections, and tell-tales. Key additions include energy status indicators providing charge status information via white, amber, red, selective-yellow, indicator blue, or indicator green light; lamp test mode enabling user-performed visual function checks of lighting systems; and enhanced driver assistance projections. Transitional provisions establish type-approval acceptance deadlines with mandatory application dates from September 2027 for M and N₁–O₂ vehicles and September 2028 for N₂–O₄ vehicles.
