Cities are wasting the potential of smart technologies by failing to realize the value of their hidden infrastructure and digital assets, according to a report published by The Climate Group, Accenture (NYSE: ACN), Arup and Horizon Digital Economy Research at The University of Nottingham. The report, Information Marketplaces: The New Economics of Cities, states that while cities are using information and communications technology (ICT) to improve their sustainability and efficiency, they are not recognizing or measuring the full value of smart initiatives and are missing the opportunity to turn unused data and infrastructure into new low carbon solutions and services.
