About a hundred public and environmental organizations appealed to the mayor of London with an open letter, in which they proposed to ban all private vehicles for one day as part of the struggle to improve the city's ecology.
Over eight thousand people and about a hundred public organizations signed a petition calling for a "Car Free Day" in London, that is, to refuse traveling on private cars in favor of public transport or bicycles.
The initiative group proposed to make this day Saturday, September 22nd and organize various entertainment and educational events on public venues. The initiative group was formed by the Friends of the Earth environmental fund, the ClientEarth legal bureau, the research group of the Royal College of London and participants in local forums in fifteen districts of the capital.
In the world practice there are enough successful examples of organizing "Car Free Days": such actions took place in Bogota, Paris and Brussels, and in Jakarta they are taken for the rule and are held weekly. In London, strict traffic restrictions were introduced only when carrying out special events, for example, the London Marathon. That is, abandoning cars has never been an end in itself. Measurements of the composition of air along the marathon runners showed a reduction in the level of contamination by hazardous impurities by 89% compared to the usual days.
