| Electric Vehicles and the Environment: Report of the 97th (May 2026) session |
| Reference Number: EVE-97-10 |
|
The Electric Vehicles and the Environment Informal Working Group held its 97th session on May 19, 2026. Discussions addressed UN GTR 22/25 including Norwegian EV demographics, a proposed Readiness Monitor concept for State of Certified Energy activities, and OICA terminology amendments replacing “monitor” with “assessment of virtual distance” in Part C. The group reviewed Phase 4 priorities for UN GTR 21 and UN GTR 25, including Minimum Performance Requirements, conditioning cycles, and lifetime requirements addressing disconnects between mileage and year thresholds. The next session is scheduled for June 16–17, 2026. |
