Two councils in the UK have pledged to ban cars for a day in September.
It is part of the European Mobility Week (EMW), which runs from 16th to 22nd September and aims to drive down emissions as well as encourage people to use greener forms of transport.
Around a quarter of domestic carbon dioxide and other greenhouse gas emissions in the UK come from transport.
The London Borough of Lambeth and the Scottish city of Aberdeen have joined other EU cities and towns to take part in the “car-free days”.
Both will close one or more streets to traffic on 22nd September and instead open them to pedestrians, cyclists and public transport.
Two other boroughs of Southwark and Glasgow will also organise a week of activities and implement one or more new permanent measures towards environmentally-friendly transport solutions.
Last year, EMW saw citizens from 44 countries explore the benefits of embracing sustainable mobility.
