ECF’s main conclusion from this study is that the bolder the measures taken by the authorities, the better the results for air quality. City authorities who want to protect their citizens from health risks due to bad air quality, have to act thoroughly. Secretary General of ECF, Bernhard Ensink, explains: “Transport systems in European cities need to be transformed drastically. Motorised traffic has to be reduced. We recommend cities to invest in large scale and high quality cycling networks and extensive car-free zones. Keep your city vibrant, by switching from motorized transport to cycling.” - See more at: http://www.ecf.com/press_release/less-cars-more-bicycle-better-air-quality/#sthash.0LN54Qz1.dpuf
