Circular cities aim to eliminate the concept of waste, keep assets at their highest utility at all times, and are enabled by digital technology.

By the year 2050, over 66% of the world's population is expected to be living in urban environments (UN 2014). This will lead to an increase in the demands of urban infrastructure and resources. 

Google and the Ellen MacArthur Foundation have recently launched a report into this entitled 'Cities in the Circular Economy: The Role of Digital Technolgy'.
