The notified report presents the technical review of the energy efficiency standard for light-duty vehicles. The review was prompted by the need to assess the effects of the entry into force of the Euro 6c emissions standard and the transition from the New European Driving Cycle (NEDC) type-approval to the Worldwide Harmonized Light Vehicles Test Cycle (WLTC). Given that the WLTC procedure has been used for the mandatory type approval of new vehicles since October 2025 and that its test conditions better reflect real-world vehicle operation, it is necessary to review the current energy efficiency standard, established pursuant to Exempt Resolution No. 5 of 2022, to ensure that it continues to provide a proper, sound, and representative assessment of the energy performance of light vehicles. It should also be noted that the energy efficiency standards have been in force since 2024. The purpose of the notified information is to inform the industry that the change to the emissions standard, made by the Ministry of the Environment (MMA) and which entered into force on 1 October 2025, does not amend or affect the energy efficiency standards currently in force.G/TBT/N/CHL/805- 2 -
