Sustainable mobility is essential for the transport transition. In addition to reducing the number of private cars, it is particularly important to strengthen environmental transport. In addition to reducing the number of private cars, it is particularly important to strengthen environmental transport. This refers to the cooperation of environmentally friendly means of transport, including public transport, cycling, walking and car sharing. Car sharing has ecological, social and economic advantages. Given that private cars are only used for an average of 45 minutes a day, car sharing has enormous growth potential if it is successfully implemented and accepted by potential users. In order to facilitate the switch from private cars to car sharing vehicles, the business model must be scaled up so that it is available nationwide.

The studies to date on the future development of car sharing are primarily user-oriented, i.e. these take into account the acceptance or non-acceptance of car sharing on the part of car sharing users as well as the associated growth potential.

The aim of this dissertation is to present the influence of relevant stakeholder groups on the car sharing business model. This includes station-based, free-floating and (e-)car sharing. The following three subject areas will be examined in more detail:

1. Expectations on car sharing providers and their business models,
2. existing opportunities for influence, and
3. Stakeholder relationships in relation to the car sharing providers and their business models.

Due to the insufficient scientific knowledge on the present research topic, an explorative examination is required. This is implemented with the help of a qualitative research approach with a quantitative part. A stakeholder analysis was carried out to identify and select relevant stakeholder groups. The author decided to take a closer look at the following eight stakeholder groups: Car sharing providers, car manufacturers, political leaders in the mobility sector, municipal leaders in the transport and mobility sector, transport associations, energy providers, interest groups and transport clubs, as well as other stakeholders involved in car sharing.

The Stakeholder Salience Model by Mitchel et al. (1997) is used to classify and evaluate the empirical results. The aim of the study is to give recommendations for action for an expansion of car sharing in Germany, taking into account the relevant stakeholder groups.
