Sustainable transport : The answer to the crisis and pollution

The expression sustainable transport indicates a transport mode that can decrease the environmental, social and economic costs generated by private vehicles such as air pollution, traffic congestion, etc..
The crisis that has affected economies around the world suggests to motorists to change their habits and to consider this new "style" for their journeys.
Car sharing was born in the USA during the Second World War where the war effort require to save petrol but is well established in Europe (the first in 1987 was the Swiss). The car isn't purchased but rented (from companies but also from people when they do not use it). A site / app / call center tells users where to find the car while the mode of "restitution " vary according to the company. Motorists who travel less than 7,000 km per year can save up to 50% with this formula , not to mention the benefits to the environment.
The other form of sustainable transport is the car pooling: the motorists who want to share their cars declares how many places have and the destination on a dedicated portal that is also used by people who are looking for a lift: in this way the cost of transport is divided between several people and the number of vehicles in circulation decreases. This formula is preferred by young people (50% of users are under 35 years old) also given the "social " value (it combines saving with the opportunity to meet new people ).
