EU - Commission Implementing Regulation Laying Down Rules, Procedures, Testing Methodologies and Administrative Requirements for the Application of Regulation (EU) 2024/1257 as Regards Brake Particle Emissions of Motor Vehicles of Categories M1 and N1

​This draft Implementing Regulation establishes comprehensive requirements for brake particle emissions of M1 and N1 vehicles under Regulation (EU) 2024/1257 (Euro 7), incorporating UN Regulation No. 179 on the Laboratory Measurement of Brake Emissions for Light-Duty Vehicles.

The draft Implementing Regulation ensures real-world representative testing and aligns with Euro 7's ambitious air quality objectives, addressing a critical and growing source of urban pollution. As vehicle engines become cleaner, brake particle emissions - now often exceeding tailpipe emissions in urban areas - demand urgent regulatory attention. 

The draft introduces stringent testing protocols to accelerate the development of low-emission braking technologies, directly contributing to cleaner urban air and public health improvements by reducing particulate matter linked to respiratory diseases and premature deaths. 

The measures provide a clear legal framework for manufacturers while safeguarding investments in sustainable technologies.

Timely adoption by summer 2026 is essential to ensure industry preparedness ahead of Euro 7's application to new vehicle types in November 2026, preventing market disruptions and enabling smooth compliance. 

​Given the need for alignment with international standards and the short adoption period, the commenting period has been reduced to 30 days.
