The document outlines the process for developing UN R40.03. It specifies that EPPR7302 (IMMA) draft proposal for UN R40.03 should serve as the basis for discussions and drafting of regulatory texts and provisions. Comments should be submitted in advance, preferably one week before the meeting. Regulatory texts and provisions will be discussed and drafted based on comments and proposals submitted before or during the meeting.

Non-binding industry guidance developed jointly by CLEPA and OICA providing internationally harmonised methodology to determine carbon footprint of passenger cars across all life cycle stages. Guidelines define four levels based on data granularity and intended use cases, from generic strategic planning to detailed supply chain reporting. Specifies methodological requirements for material production, parts production and vehicle assembly, use stage, and end-of-life stages; includes requirements for data collection, energy modelling, waste treatment and recycling, and reporting. Applies 100-year global warming potential characterisation factors from IPCC, with dual reporting of carbon footprint including and excluding biogenic CO₂ uptake. Establishes primary data share indicators and chain of custody requirements for supply chain transparency.

Draft agenda for the 44th session of the IWG on A-LCA scheduled for 13 October 2026. The session will cover discussion on next steps, revision of terms of reference, OICA and CLEPA industrial guidelines, review of report to GRPE, and any other business including updates on J3341_202608.

Draft agenda for the 52nd session of TFTA on 8 and 9 October 2026 in Brussels and remotely. The main target of the meeting is brainstorming on C3 test method. Discussion items include framing the C3 challenge, C3 tyre segmentation to categorise diverse tyre groups and duty cycles into manageable regulatory groups, methodological ideation for simplified C3 testing approaches, and funding and resource allocation. Additional items include C1 outcome discussion with Korean test centers regarding circuit SRTT abrasion level range and C2 status on ongoing test campaign.

Discussion document presenting general considerations for a C3 tyre abrasion test method. Topics addressed include objectives for reducing C3 tyre wear, quantification of C3 abrasion relative to overall and C1 abrasion, C3 tyre life including retreading effects, operational factors influencing tyre wear such as fleet optimization and load management, and environmental concerns regarding C3 microplastics and chemical requirements.

ETRTO analysis of the European C3 tyre market segmentation, emission levels per tyre segment, and vehicle configurations. ETRTO recommends focusing on Segment A (Heavy Duty Tyres 22.5 for Long haul and regional usage), which captures approximately 71% of wear emissions. ETRTO evaluated five alternative methods to the convoy method using criteria including time to market, representativeness, regulatory suitability, and cost. ETRTO concludes the convoy method focusing on Segment A is the only feasible method given the mandated timeline, despite drawbacks including test duration and environmental impact.

Presentation of fka’s tyre technology division capabilities in testing, simulation and research. Describes fka’s collaboration with ZF on developing a C3 tread wear drum test rig to be operational in Q1 2027. Outlines fka’s offer to support joint development and validation of C3 drum abrasion methodology with TFTA members, requiring funding commitments or test workload from interested partners. Discusses technical considerations including drum curvature effects, surface texture replication, testing capacity estimates, and environmental impact of convoy versus laboratory testing methods.

Document presents Japan’s heavy-duty vehicle market structure, C3 tyre classification and market share, and proposes concepts for vehicle and indoor drum test methods for C3 tyre abrasion testing. The vehicle test concept recommends establishing a single test method based on typical operating conditions using the WHVC mode, with the drive axle as reference. The indoor drum test method is proposed as preferable due to higher test accuracy and lower environmental impact compared to vehicle testing. Test conditions under consideration include input conditions based on WHVC with curve and slope running modes, inflation pressure and load aligned with vehicle specifications, drum diameter potentially increased from 3 m, and drum surface conditions based on C1 tyre definitions.

Note by the secretariat reporting on GRPE activities. WP.29/AC.1 adopted all proposals including a new UN Regulation on tyre abrasion. WP.29 agreed to host a demonstration of EV retrofitted vehicles at its 200th session in November 2026. The first meeting of the IWG on prioritization identified topics for discussion including common understanding of prioritization, high-level review of current activities, possible approaches to define prioritization, criteria for establishing new groups, and how to enhance efficiency of informal working groups and task forces. Mongolia acceded the 1958 Agreement. Light duty fuel efficiency improvement trajectory and HDV fuel efficiency measurement harmonization were tackled in GRPE. The UNECE secretary was invited to join a UNEP partnership on battery circularity to be launched in 2027.

This document addresses open issues regarding the Fast Charge Power Curve Resolution draft still under technical discussion where no consensus has been reached by the F&SC Cluster at submission of ECE/TRANS/WP.29/GRPE/2026/52. Open points cover measurement system requirements, test vehicle conditions, test preparation, vehicle preparation phase, parameter definitions, test evaluation tolerance criteria, and data processing and calculation of KPIs including maximum charging power, average charging power in 10–80% SoE range, power curve from 10% SoE to full charge, charging duration, and recharged energy or range in 10 minutes.

Terms of Reference for the UNECE EV fast- & smart-charging cluster, a joint activity of WP.5 e-mobility Task Force and the IWG on EVE. The cluster aims to promote user-friendly, safe and scalable adoption of fast and smart charging functionalities of electric vehicles and their integration in the energy system. Task A develops a new WP.29 resolution on DC Fast Charge Power Curve (FCPC) of electric vehicles in three phases: Phase 1 establishes a harmonized test procedure for light duty vehicles; Phase 2 develops requirements for consumer information and minimum performance requirements; Phase 3 investigates expansion to heavy duty applications. Task B inventories the need for harmonization of other recharging capabilities and recharging documentation, including collecting existing international standards and initiatives, identifying discrepancies and gaps, and issuing a harmonized standardization/regulatory roadmap for smart and bi-directional charging of EVs by vehicle category. Chairmanship is held by The Netherlands from January 2025 to October 2027.

Document presents technical challenges to defining retrofit kit types for electric conversion and approval processes. Identifies that retrofit kit type perimeter depends on the regulation considered, with different requirements across UN R10, R13, R100, R85, R138, WLTP, R79, R39, R51, R89, R121, and R122.
