Proposal to update UN R27 in accordance with technological progress by establishing provisions for the use of fluorescent retro-reflective strip, enabling the consolidation of currently separate fluorescent (daytime) and retro-reflective (nighttime) striping.

Combined GTB and CLEPA proposal, superseding documents GRE/2011/46 and GRE/2012/25, to update UN R27 in line with technological progress and performance-based methodologies. The main changes are:

a) Revised provisions to combine color boundaries for the night time color,
b) Replacement of Illuminant C with Illuminant D65 in the measurement of fluorescent materials,
c) Alternative methods introduced for instrumental measurement of the fluorescent color,
d) New Annex 10 to replace reference to ISO 105,
e) Clarification of the wind test (Annex 5),
f) Standardization of the test surface representing the road,
g) Simplification of the test device for clearance to the ground in Annex 3,
h) Amendment of COP requirements, and
i) 36-month transitional period in a new paragraph 14.

Proposal to introduce new Class 5 devices made solely of retro-reflective plates with chevron type pattern to be applied to special utility vehicles or trailers not regularly covered by standard rear marking plates in order to harmonize existing national requirements.

Proposal to introduce a new Class F marking designed with chevron-type pattern to be applied to special utility vehicles or trailers not normally covered by standard contour marking materials in order to harmonize national requirements making use of such markings.

This proposal introduces new class 5 devices made solely of retro-reflective plates with chevron type pattern to be applied to special utility vehicles or trailers not regularly covered by standard rear marking plates. The amendment also seeks to harmonize the text to cover various national requirements.

This proposal introduces new class F marking materials designed with chevron type pattern to be applied to special utility vehicles or trailers not ordinarily covered by standard contour marking materials. The proposal also attempts to harmonize a number of national requirements.

Proposal to ensure that the introduction of the new class F marking materials does not conflict with the mandatory requirements for existing class C materials. Class F markings are designed with alternate stripe pattern to be applied to special utility vehicles or trailers not regularly covered by standard contour marking materials requires amending the definitions.

Recommendations by AECC, CLEPA, EUROMOT, and OICA for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Revised recommendations by AECC, CLEPA, EUROMOT, and OICA, pursuant to discussions during the GRPE-68 session, for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Proposal to ensure that all replacement pollution control devices conform with the intent of UN R49 and to align UN R49 in this regard with Regulation (EU) 2016/1718. CLEPA proposes the establishment of a new annex under UN R49-05 R.49-05 to restrict the approval of a replacement device to one that “enables the engine and vehicle to comply with the rules with which it was originally in compliance”.

This proposal intends to establish a definition for ‘Hydrogen ICE vehicle’ and the related method for ‘trip validation’

This document aims at transposing UN GTR 24 into a new UN Regulation on uniform provisions concerning the approval of non-original and identical replacement brake parts with regards to particle emissions.

This document is also available with tracked changes.

Additional validation work to support the the proposal to:
• Provide new evidence based on additional analysis.
• Compare MAW window validation and RDE results using work, fuel, and CO₂-based parameters.

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.

Proposal to insert a new definition of hydrogen ICE vehicle, add a note to paragraph 6.1 specifying emissions requirements for 4-phase and 3-phase WLTC analysis, amend paragraphs 8.2, 9.3.1, 9.5, 10.2, 10.6, and 10.7 to clarify trip validity assessment procedures, amend Figure 6 to reflect updated assessment procedures, amend Table A4/1 to add engine fuel flow parameter and clarify mandatory parameters for hydrogen ICE vehicles, insert a new row in Table A5/1 for hydrogen, amend Annex 6 paragraph 3.2.2 to require engine speed and torque recording for hydrogen ICE vehicles, insert hydrogen in Table A7/1, retitle Annex 8, amend Annex 8 paragraph 1 to clarify application of moving averaging window method, and add new Annex 8a establishing an alternative moving averaging window methodology based on engine work for hydrogen ICE vehicles, and amend Annex 11 paragraphs 2, 3.1, and 3.2 and Figure A11/1 to incorporate work ratio calculations for hydrogen fuel tests.

Explanatory document on proposed amendments to UN R168 to enable real driving emissions testing of hydrogen internal combustion engine vehicles. The work-based approach replaces the CO-based moving averaging window methodology currently inapplicable to hydrogen-fuelled vehicles. Engine speed and torque data replace carbon monoxide to define window size and calculate the RDE/WLTP work ratio. Testing of a light commercial vehicle demonstrates the methodology’s practical applicability under regular and severe driving conditions, with results processed through independent post-processing tools.

The objective of this document is to provide recommendations for the minimum quality of market fuels (i.e. gasoline and diesel) that should be introduced concurrently with the corresponding emissions standards. They complement the motor vehicle and NRMM pollutant emission standards that a country or a region may be considering to introduce.
