Proposal to establish a globally harmonised laboratory methodology for measuring brake particulate matter and particle number emissions from Heavy-Duty Vehicles. The UN GTR defines the test cycle (Worldwide Harmonized Heavy Duty Brake Cycle), minimum system requirements, test conditions, equipment preparation, brake dynamometer capabilities, brake enclosure design, sampling tunnel design, and sampling plane design. It applies to vehicles of categories M₂, M₃, N₂, N₃, and O₃, O₄ concerning braking, covering both friction braking systems (disc and drum brakes). The regulation includes requirements for brake bedding procedures, emissions measurements, calibration, and ongoing quality controls. A version with tracked changes is available.

Proposal to establish a new supplement to UN Regulation No. 179, improving and correcting brake emissions measurement procedures for light-duty vehicles of categories M₁ and N₁. The regulation applies full-friction braking testing on brake dynamometers using the WLTP-Brake cycle comprising ten trips and 303 brake deceleration events. Testing includes three sections: cooling air adjustment, brake bedding with five cycle repetitions, and emissions measurement with three cycle repetitions. Compliance is demonstrated by measuring PM10 and SPN10 emissions from brake corner emission family parents, with whole-vehicle emissions calculated using friction braking share coefficients specific to vehicle electrification types. PM10 limits are 3 mg/km for M₁/N₁ vehicles and 5 mg/km for N₁ Class III/N₂ vehicles. Conformity of production requires annual testing of brake corner emission families with statistical evaluation per decision charts through 31 December 2029 (Phase I, PM10 only), with Phase II from 1 January 2030 evaluating both PM10 and SPN10. A version of this document with tracked changes is available.

Proposal to modify UN GTR No. 24 with respect to laboratory measurement procedures for brake emissions of light-duty vehicles. This amendment improves and corrects the testing procedure, including detailed requirements for test system setup, cooling air conditioning, brake dynamometer specifications, WLTP-Brake cycle execution, emissions measurements for particulate matter (PM2.5, PM10) and particle number (TPN10, SPN10), calibration protocols, and reporting of results. The regulation defines brake corner emissions families, friction braking share coefficients for different vehicle electrification types (ICE, HEV categories, PEV), and test procedures using fully-enclosed brake dynamometers with isokinetic sampling systems. A version with tracked changes is available.

Proposal to include testing of vehicles with limited speed. The document sets out the laboratory measurement procedure for brake emissions from light-duty vehicles of categories M₁ and N₁, including vehicles with maximum speed below the Base cycle maximum speed. Testing involves three sections: cooling air adjustment, brake bedding with five repetitions of the WLTP-Brake cycle, and brake emissions measurement with one WLTP-Brake cycle. Brake corner emission families are tested on a component test bench under full-friction braking conditions, measuring PM₁₀ and SPN₁₀ emissions. Compliance is demonstrated using brake corner emissions family parents. Conformity of production requires monthly sampling and testing of brake components, with results evaluated using statistical decision charts through 31 December 2029 for PM₁₀ and thereafter for both PM₁₀ and SPN₁₀.

Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg at the manufacturer’s request as an extension from vehicles with reference mass not exceeding 2,610 kg, and to allow type approval of special purpose vehicles of categories M₁, M₂, N₁ and N₂ regardless of their reference mass at the manufacturer’s request, with the manufacturer demonstrating to the Type Approval Authority that the vehicle in question is a special purpose vehicle.

Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg as direct approvals rather than only as extensions based on approved configurations below 2,610 kg. The modification permits manufacturers to obtain type approval for vehicles within the 2,610 kg to 2,840 kg reference mass range regardless of whether lower-mass configurations of the same vehicle type are approved, addressing concerns that the previous restriction created market distortions affecting different manufacturers differently, a concern heightened by fleet electrification.

Proposal to amend para. 1 to clarify that type approval may be granted to vehicles of categories M₁, M₂, and N₁ with a reference mass not exceeding 2,840 kg at the manufacturer’s request, without requiring an existing approval of a configuration below 2,610 kg. The current wording restricts approval between 2,610 kg and 2,840 kg to extensions of existing approvals, creating market distortion. The concern is becoming more relevant with fleet electrification, as electrified vehicles are heavier and require different type designations in emissions-based regulations.

This document presents a comprehensive technical roadmap on smart and bidirectional charging for electric vehicles. It reviews standards governing interfaces between vehicles, electric vehicle supply equipment and electricity grids; identifies remaining gaps in standardisation, certification and testing; and recommends actions for global harmonisation. The roadmap focuses on light-duty vehicle categories (M₁, M₂ ≤5 t and N₁), covers communication protocols including ISO 15118-20 and Amendment 1, grid codes across multiple regions, and battery data identifiers under UN GTR No. 22. Key findings include: proprietary solutions and vendor lock-in remain prevalent; ISO 15118-20 has not yet achieved broad interoperability in practice; grid-code conformance regimes for AC bidirectional charging lack mature certification pathways; and end-to-end conformance testing remains immature in major regions. Main recommendations include establishing a Global Task Force on Bidirectional EV Charging, clarifying capability communication, ensuring regulations track standards evolution, extending electromagnetic compatibility requirements to partial-load operation, and maintaining consistency between automotive and energy-sector cybersecurity requirements.

Table presenting subjects under consideration by GRPE, including improvement of exhaust emissions requirements for real-world performance, introduction of Euro 7 emission provisions for light and heavy-duty vehicles, gradual updating of UN R40 to state-of-the-art emission limits, decarbonization implementation, life cycle assessment, new propulsion energy development, EV/HFCV retrofit systems, particulate emissions reduction, brake emissions, tyre wear emissions, and screening of GRPE Regulations for autonomous vehicles readiness. Timelines range from October 2025 to March 2028.

Proposal to amend Appendix 5 (Devices for monitoring on board the vehicle the consumption of fuel and/or electric energy) of Working Document ECE/TRANS/WP.29/2026/153 to specify parameters to be determined, stored and made available by OBFCM devices for pure ICE and NOVC-HEVs, OVC-HEVs, PEVs, NOVC-FCHVs, OVC-FCHVs, and mono-fuel gas vehicles. The modification excludes a manufacturer-specific parameter and aligns with international standards for OBFCM requirements.

Explains the proposal 95-15

Japan presents positions on working documents for UN R168 (Real Driving Emissions). Japan does not accept the Level 1C concept, proposes deleting the type-approval scheme for equipment to eliminate unnecessary burden, and recommends adding technical requirements for laboratory equipment instead. Japan expresses technical concerns regarding sampling line temperature limits, text structure requiring restructuring, and hydrogen ICE provisions including dry-wet correction applicability and trip validity methods for bi-fuel vehicles.

Industry guidelines developed jointly by CLEPA and OICA to provide a harmonised methodology for determining the carbon footprint of passenger cars through their full life cycle, from material extraction through production, use, and end-of-life. The guidelines establish four levels of assessment based on data granularity and intended application (ranging from public policy analysis to detailed supply-chain reporting), with fixed methodological approaches for Levels 3 and 4. They specify treatment of GHG emissions including biogenic carbon, land use change, and fossil emissions; define data quality requirements including primary data collection and allocation procedures; and establish system boundaries across material production, parts and vehicle assembly, use, and end-of-life stages, employing the Circular Footprint Formula for material recycling assessment.

Joint OICA and CLEPA workgroup presentation on industry guidelines for life cycle assessment of passenger cars and parts. The guidelines establish a common global methodology for LCA data exchange along the supply chain, independent of regulatory development. Key technical points include defining functional units for passenger cars and a declared unit for parts, specifying primary and secondary data requirements, addressing chain of custody through aligned models and mass balance approaches, allowing mixed energy modelling approaches with market-based modelling for decarbonisation efforts, introducing representative vehicles for full vehicle LCA reporting, and introducing representative parts to simplify supplier reporting to OEMs.
