This report of the "PeerSharing" project presents the findings of an exploratory pre-study on the assessment, practice and perception of P2P sharing, based on telephone interviews with users and non-users. The interviews reveal a fairly high familiarity with the concept of the “Sharing Economy”. Most people hold a positive attitude towards it. Ecological benefits of P2P sharing are obvious to most respondents and many expect positive social effects as well. The main motive to engage (potentially) in P2P sharing is economical. Although ecological benefits are both expected and considered good by most respondents who (partly) do reflect current consumption patterns critically, ecological motivations are less important. The findings illustrate the great social acceptance of P2P sharing. They will feed into the development of a standardized survey that will provide quantified insights into the practice and perception of P2P sharing in Germany.
