  • Urban greening reduces noise pollution

    Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise. The Environmental Noise Directive (2002/49/EC)1 ...
