As the world becomes more urbanized, the challenges facing cities increase, making them more vulnerable to the effects of climate change, to which the transport sector is a major contributor. Despite progress in making private vehicles more sustainable and efficient, a radical change in travel behavior remains essential. One of the most promising solutions is carpooling. The aim of this paper is to highlight the factors that favor the uptake of this form of mobility, including socio-economic characteristics and individual attitudes, and to describe the economic, social and environmental impacts of carpooling. It also analyses the barriers to its diffusion and the policies that support its uptake. Shared mobility, such as carpooling, has the potential to play a critical role in promoting social inclusion by offering affordable transportation options to underserved communities and contributing to a just transition toward a more sustainable and equitable urban transport system.
