This publication has been developed by ITU within the framework of the United for Smart Sustainable Cities (U4SSC) initiative. It provides a visual overview on a city’s performance to benchmark in the Key Performance Indicators for Smart Sustainable Cities. The U4SSC KPIs are based on Recommendation ITU-T Y.4903. The visual representation highlights a city’s performance in each dimension and subdimension of the KPIs for SSC based on the inherited benchmark value of each indicator. This set of KPIs for SSC was developed to establish the criteria to evaluate ICTs’ contributions in making cities smarter and more sustainable, and to provide cities with the means for self-assessments.
