A set of Sharing Cities principles — with no claim of comprehensiveness — that people could apply, adapt, and add to, according to their local circumstances. The principles should be thought of as aspirations rather than instructions; guiding stars rather than a map. Here are the principles (with detailed descriptions below), written with the help of Shareable staff and our community, with inspiration from many others in the movement and beyond.

Solidarity[edit | edit source]
Sharing Cities represents a revived story about cities that recognizes community as the heroic protagonist in urban transformation. Aristotle, the leading philosopher during Athens' golden age, believed that the city existed for the well-being of its people. In this story, people work together for the common good rather than compete for scarce resources. This age-old wisdom challenges popular narratives that portray high technology and competitive markets as heroes in the story of cities. A Sharing City is of, by and for all people no matter their race, class, gender, sexual orientation, or ability. In other words, Sharing Cities are primarily civic, with residents focused on taking care of each other, their city, and partner cities too. Their primary function is to produce residents capable of working together for the common good, the foundational skill that makes all other things possible in society. Looking forward, and to paraphrase the Buddhist monk Thích Nhât Hanh, the next Buddha will be community. A multitude of loving, human-scale communities managed by capable residents is how we'll protect all life on earth. The solution is us.
Distributed architecture[edit | edit source]
Sharing Cities support a commons-oriented shift from an industrial model of urban development, which centralizes the various functions of a city in separate zones for batch processing by bureaucracies, to a networked architecture, which distributes functions throughout the city for real-time processing through open networks. The distributed model is characterized by mixed-use zoning, modular architecture, event-based use of multifunction assets, and on-site processing of energy, water, and waste. It also enables new ways to manage resources (access over ownership) and multiple types of currencies (fiat, local, reputation) and property (public, private, and community). If managed democratically, Sharing Cities’ distributed architecture has the potential to dramatically increase the health, wealth, and resource efficiency of all city residents.
Private sufficiency, civic abundance[edit | edit source]
To quote George Monbiot, "There is not enough physical or environmental space for everyone to enjoy private luxury... Private luxury shuts down space, creating deprivation. But magnificent public amenities – wonderful parks and playgrounds, public sports centres and swimming pools, galleries, allotments and public transport networks – create more space for everyone, at a fraction of the cost." Civic abundance should include public schools, spacious squares, expansive walkable cityscape, extensive bikeways, lending libraries, Fab Labs, pocket parks, coworking spaces, cultural centers, child care co-ops, food pantries, and more. In fact, each neighborhood should have a mix of civic amenities tailored to their needs. Sharing Cities are a path to abundance and celebration, not deprivation and drabness that downscaling consumption often suggests.
Common needs, co-designed solutions[edit | edit source]
Sharing Cities focus on common needs and pragmatic, community-developed solutions as opposed to top-down, one-size-fits-all solutions. This requires co-design, experimentation, learning, and iteration by the community. It also requires avoiding unnecessary replication of divisive national politics at the local level, which can take the focus off common needs and solutions. To paraphrase Father Arizmendi, the founder of Mondragon cooperative: ideologies divide, common needs unify.
Transformation over transaction[edit | edit source]
Sharing Cities emphasize solutions that build residents’ ability to work together. This is preferable to solutions that reduce provisioning to mere economic transactions. Services that build collaborative capacity can produce transformative social goods, lead to new collaborations, and help put a community on a positive, long-term trajectory. As in the case of northern Italy, a strong civic culture can last for centuries and is a precondition for long-term shared prosperity. Moreover, this emphasis creates space for individuals to develop as human beings. As Desmond Tutu has said, "a person is a person through other persons." We need each other to become fully human.
Local control, global cooperation[edit | edit source]
Sharing Cities create many democratic, local centers of power that cooperate globally. This cooperation can take many forms. For instance, city governments could develop an open-source urban commons technology stack together. Think Airbnb and Uber, but with locally-owned, democratically-controlled instances of services that are also connected through a global platform. This is what futurist José Ramos calls "cosmo-localization." It's a strategy to achieve scale while building solidarity.
Impact through replication, not just scale[edit | edit source]
Sharing Cities can systematically encourage the documentation of local solutions so they can be adapted and replicated in other places. Here, solutions are only loosely connected. This process requires minimal technology and administrative investment. Scale is not the only path to dramatic impact. Both scale and replication strategies should be pursued.
Cross-sector collaboration, hybrid solutions[edit | edit source]
To thrive, the urban commons must adapt to the dense institutional web of the city. Unlike isolated rural commons, urban commons have no choice but to negotiate mutually beneficial relationships with government and the market. This must happen at the project and city scale as demonstrated by Bologna’s urban commons and the Co-Bologna project. Sharing Cities’ solutions are often hybrids of the commons, government, and market.
Systems thinking, empathy[edit | edit source]
City residents, urban planners, local politicians, and single-issue advocates need to become more aware of how different functions within a city interact with each other and are shaped by the surrounding region. For instance, the impacts of land use, transportation, housing, and jobs on each other are profound. There is an increased need for them to be planned together, and at a regional scale. Stakeholder groups must have empathy for one another and co-design urban solutions that optimize for the whole, not just one or a small cluster of issues or jurisdictions.
Build and fight[edit | edit source]
Sharing Cities must seize the immediately available opportunities for commons development. Many commons projects need little if any funding or permission to start. While political change is necessary, it's unwise to depend solely on or wait passively for it. Today’s urgent challenges require immediate action. That said, a completely independent, parallel economy is not possible. The urban commons need to be fought for politically too, and that takes long-term vision and commitment. To borrow from Cooperation Jackson's strategy, we must build and fight for Sharing Cities.
Competitive advantage through quality of life, security, and distinctiveness[edit | edit source]
Sharing Cities are great places to live because they foster healthy relationships and natural environments, top contributors to health and happiness. Sharing Cities enhance social and environmental resilience. In an increasingly unstable world, the advantages of a supportive community and an accessible resource base represent an attractive safety net. In addition, Sharing Cities are distinctive because the commons preserve local culture and tradition. This distinctiveness helps them compete globally. The best cities will increasingly be known by the unique, and even transformative, experiences they make possible. The 21st century version of cathedrals, which drew millions of people to European cities during the Middle Ages, will be the uplifting social interactions, safety, and everyday joy experienced in Sharing Cities. As the old Irish proverb goes, it is in the shelter of each other that the people live.
