In April 2018, the Urban Sharing team performed a mobile research lab in San Francisco, USA. The researchers met with representatives from various sharing platforms, city authorities, civic associations and the academic community. They explored the impacts of sharing on the city in terms of its economic, environmental and social effects, the ways in which the City of San Francisco engages with sharing and the degrees to which sharing is accepted and used by the citizens. Among the interviewed organisations were, for instance, AirBnb, Tool Lending Library in Oakland, the San Francisco Transportation Authority, the City Office of Short Term Rentals and the Sustainability Research Center for Transportation at the University of California in Berkeley. In addition, with support from Neal Gorenflo from SHAREABLE, the team conducted three focus groups with citizens of San Francisco Bay Area who engaged in the sharing of space, cars, bikes and household items. The field trip provided a valuable insight into how sharing activities evolve in the city, which is considered the birth place of the modern sharing and collaborative economy and the dot-com business. The research reflections are summarised in the snapshot below:
