Document title On-Board Monitoring and Environmental Vehicle Passport: Proposal for a new UN Regulation
Date 29 Dec 2025

Proposal to establish requirements for the type approval of on-board monitoring (OBM) systems that:

  1. detect vehicle exhaust emissions exceeding prescribed limits,
  2. monitor propulsion battery storage capacity and health,
  3. warn drivers as warranted, and
  4. communicate such information off-board.
The provisions include specifications for an “environmental vehicle passport (EVP)” to be issued by the vehicle manufacturer, for the format, data, and off-board communication methods for the EVP and for the in-vehicle display of environmental performance data. The provisions also address manipulation devices and strategies. Japan abstained from the vote to adopt.
