Quiet and clean vehicles
The operating noise of municipal vehicles can be very annoying, especially in residential and rest areas. For resident protection, municipalities should use low-noise vehicles and busses. Hence, the Blue Angel sets maximum permissible sound power levels for street sweepers, garbage trucks and busses. In addition, for environmental and health protection these vehicles must meet stringent exhaust emission and particulate matter standards.
Benefits to health and environment
- protection from inner-city road traffic noise
- reduction of exhaust emissions and particulate matter in residential areas
