8. | OIL #57: Utility factor

Presentation of the EU UF values.

Japan presents proposal for GTR text that has been submitted to the drafting coordinator. Remark from ACEA: proposal still has to be discussed within Sub group EV.
Regional UF from contracting parties will be introduced in the GTR, when they are available.
There is a question regarding what regional options that should be introduced in the GTR, limit values, reference fuels, UF etc.
OICA request that – if possible – regional UF from other CP should be included in the GTR in phase 1b. There is also a risk of discrepancy between regional legislation and GTR text if UF is changed in a region.
Further political discussion regarding the inclusion of regional options in the GTR will take place in GRPE.

First proposal for GTR text of regional UF is presented by Japan. Proposal for harmonized procedure to determine UF (methodology) will be presented on coming meeting.
The ambition should be to include harmonized methodology to determine UF in phase 1b.
Start point to compare existing methodology from different regions, including technical report from EU. This will be done until January meeting. In order to decide if it is possible to include harmonized methodology in phase 1b.
