Co.Exist stila una classifica delle 10 città più SMART del mondo.
E definisce cos'è una città SMART: "The term "smart cities" is a bit ambiguous. Some people choose a narrow definition--i.e. cities that use information and communication technologies to deliver services to their citizens. I prefer a broader definition: Smart cities use information and communication technologies (ICT) to be more intelligent and efficient in the use of resources, resulting in cost and energy savings, improved service delivery and quality of life, and reduced environmental footprint--all supporting innovation and the low-carbon economy".
La città più smart è Vienna, seguita da Toronto.
Chiude la classifica Barcellona.
