Review of the background research and current draft of the reference guide to worldwide electric vehicle environmental regulatory requirements.

Japanese comments on the recommendations/guidelines proposed in the draft electric vehicle environmental regulations reference guide.

Status report on the work to develop standards for heavy-duty vehicle dual-fuel retrofit systems.

Spreadsheet detailing the status of issues being addressed under the heavy-duty vehicle dual-fuel retrofit systems program.

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

Revised presentation of Japanese regulatory plans and views on the working draft of a possible global technical regulation concerning on-board diagnostic systems for L-category vehicles (mopeds, motorcycles and derivatives).

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.

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.
