Low emission zones are improving health, studies show

Review of research finds particularly clear evidence that LEZs in cities reduce heart and circulatory problemsAn increasing number of research studies are showing that low emission zones (LEZs) improve health.More than 320 zones are operating across the UK, Europe and notably in Tokyo, Japan. These reduce air pollution across an area by curbing the number of highly polluting vehicles, normally older diesels. Schemes, including London's ultra-low emission zone, can improve air quality. This should lead to improved health, but does this actually happen? Continue reading...
