Sustainability has consolidated as a global paradigm. Consequently, different sectors have adopted its principles to develop better practices for the environment and society. Within the transportation field, carsharing has emerged as a potential solution to reduce congestion and carbon emissions.  In Stockholm, one of the world’s leading cities on the sustainability agenda, carsharing has been growing steadily, with more companies participating in the market and more users adopting it. Likewise, the local administration conceives it as a tool that could contribute to sustainability. However, the private and the public sector assert that carsharing is far from its potential. The conditions established by the local government could be a factor that explains this situation.  Accordingly, this thesis aims to analyze Stockholm’s policy and administrative framework for carsharing, with a focus on its coordination and implementation. This was made by conducting interviews with public officers and carsharing companies and by analyzing Stockholm’s policy and administrative documents related to carsharing through the lens of policy integration and coordination. The illustrative example of charging stations and its implications for carsharing is used to analyze policy coherence, and to reveal the implementation divergences between the private carsharing sector and local public authorities.
