To understand possibilities and barriers for ride-sharing in work commuting, 451 persons living in the same suburban area and working at the same site were invited to join a ride-sharing program and use a mobile application. Two quantitative web surveys and 16 in-depth interviews have been performed. The results have been analysed using social practice theories as an analytical lens. The participants understood the benefits with the ride-sharing practice, but out of the 451 invited participants, only 8 downloaded the required mobile application for the ride-sharing program. Different to previous results in the literature, trust and security were not seen as issues in this case. Instead the expected loss of flexibility was seen as the main barrier. The participants found a meaning in “being a green commuter” and understood that ride-sharing could contribute to decrease challenges of congestion, environmental impact, and overfull parking places. However, they rated their own current flexibility and convenience in commuting higher than the expected benefits from ride-sharing.
