BlaBlaCar, Drivy, Leboncoin, placedelaloc, sharevoisins… the Internet and smartphone technology boom have made it increasingly easy to get in touch with people seeking to exchange or lend goods, to hire a car or share a ride. Such collaborative practices between individuals are long-established, but they are being renewed and strengthened through digital platforms. These “new” consumption trends have great potential from an economic (purchasing power gain) and social (strengthening social ties, friendliness) perspective, but also – and particularly importantly – from an environmental standpoint: optimizing the use of goods, reducing the number of kilometres travelled in private cars, etc. The collaborative economy could therefore be a sustainable solution to a crisis, a way to recreate the social links and open the way for a greener economy.

Recently, the academic world has entered into this field of research and has raised a note of caution regarding the promises offered by these new practices, showing their limits in terms of social and environmental sustainability. Realizing the potential of the collaborative economy thus depends on several conditions: the quality of shared goods, a rebound effect in terms of consumption, substitution between modes of public transport and car-sharing, etc. The collaborative economy and its related digital platforms are therefore not sustainable by nature. Their contribution to environmental protection depends on several conditions that are all levers of action – especially for the public authorities – to make collaborative economy as sustainable as possible.
