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”.

Report covering the reactivation of the WLTP (light vehicle emissions GTR) informal working group and its work on “Phase 1b” aimed at refining the original GTR currently pending adoption before the World Forum.

Progress report on activities concerning environmental issues related to electric vehicles.

Review of main issues concerning the measurement of sub-23 nm particles in vehicle exhaust, including work on NRMM vehicles.

Review by the Particle Measurement Program expert group of research on airborne particles from non-exhaust sources, especially particulates from brake friction materials and tires. The PMP group is evaluating whether such non-exhaust particulates represent an appropriate and feasible concern for further consideration as a possible regulatory issue.

Pursuant to GRPE 68th session discussions, further updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

Further updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

Status report on the group’s activities to develop amendments to GTR No. 2 on motorcycle emissions and new global technical regulations concerning L-category vehicle propulsion systems. The group’s priority interests include targets include evaporative emissions and on-board diagnostics testing, followed by tests for tailpipe emissions after cold start. Other interests include tailpipe emissions test at (increased) idle / free acceleration; emission test of crankcase gases; durability testing of pollution control devices; and measurement of CO2 emissions, fuel consumption, electric energy consumption and electric range determination; procedures to measure power and torque for propulsion technologies fitted on L-category vehicles; and uniform measurement of maximum design vehicle speed and/or power for restricted L-category vehicles.

Status report on the group’s current activities, including work on a new regulation covering heavy-duty dual-fuel retrofit systems.

Report to the GRPE on the project to standardize WP.29 terms used in reference to vehicle propulsion systems.

Request for guidance from Germany on the possible further development of the regulation on replacement catalytic converters pursuant to the findings of a German study. The request particularly asks whether the regulation should require improved durability and emissions performance and whether a working group should be established to develop specific proposals. The document includes the findings on the emission performance of approved pollution control devices under the current UN R103.

Updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

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”.

Draft of the Electric Vehicle Regulatory Reference Guide concerning worldwide environmental regulations submitted to the GRPE by the EVE informal working group chair.

Report of the working group developing emissions and fuel economy test procedures for heavy-duty hybrid vehicles to the 68th session of the Working Party on Pollution and Energy.

Draft technical report prepared by the expert subgroup on the development of the WLTP driving test procedure intended to accompany the draft global technical regulation on light-duty vehicle emissions and fuel consumption. The document explains the development of a test procedure intended to represent typical driving characteristics around the world.

Report on items of relevance to GRPE (vehicle pollution and propulsion) from the June 2013 (160th WP.29) and November 2013 (161st WP.29) World Forum sessions.

Administrative information concerning the GRPE session.

Background information gathered in Korea to support the proposal for a new regulation to protect vehicle users with regard to harmful airborne chemical compounds originating from the materials used in vehicle interiors.
