Summary
The European Union is introducing the first rules to limit brake emissions to help reduce pollution. New regulations will set limits on particles from brakes, and the auto industry is exploring new methods to meet these standards. These changes might lead to greener brake pads that could be more expensive.
Key Facts
- Brake dust and tire wear contribute significantly to pollution in cities.
- New EU rules (Euro 7) will limit brake emissions, starting next year.
- Current brakes emit about 8.8 mg/km of PM10 particles.
- By 2035, EU regulations aim to cut brake emissions by 27%.
- China is expected to introduce similar rules by 2025, focusing on even smaller particles (PM2.5).
- Manufacturers can reduce brake emissions by strengthening brake discs or changing brake pad materials.
- Different regions use different materials for brake pads, such as low-steel or non-asbestos organic pads, based on performance and comfort needs.
