Since the Earth Summit in Rio de Janeiro in 1992, sustainable development has gradually become a key issue for public policy in many countries. Despite many global efforts - for example - to reduce carbon dioxide emissions into the atmosphere, most small initiatives are being taken at the local level.
Take the example of sustainable mobility in cities. The majority of urban agglomerations have been designed or redeveloped for cars. In order to limit the use of cars, various devices have been put in place, such as the introduction of urban road tolls (for example in Singapore, London and Stockholm), the removal of parking lots in inner city centres, or more recently the installation of eco stickers (road tax) for polluting vehicles in Paris.
In parallel, many French cities have seen a reduction in car use in favour of more sustainable forms of transport. As well as public transport such as trains, buses or trams, bikes and walking are alternative solutions to cars. However, depending on the urban environment, bicycling or walking is not always possible, or is dangerous.
