"Today’s urban environments present extraordinary opportunities for how we can share and collaborate... The approach of a sharing (and collaborative) economy marks a significant turn from our traditional methods of consumption. Choosing transport based on safety record, loaning household tools rather than buying them and getting home-cooked food from a neighbour rather than a restaurant are just some of the ways in which sharing practices are evolving in cities. While sharing may often decrease the cost of access, it also has the potential to address long-term societal challenges such as making cities more inclusive and building social connections between groups that might otherwise never have interacted. In experimenting with sharing practices, however, cities will also have to be agile in addressing externalities and disruption to their planning processes, policy formulation and regulatory structures."
