KPIs on Smart Sustainable Cities

The U4SSC developed a set of international key performance indicators (KPIs) for Smart Sustainable Cities (SSC) to establish the criteria to evaluate ICT´s contributions in making cities smarter and more sustainable, and to provide cities with the means for self-assessments in order to achieve the sustainable development goals (SDGs). 

Over 50 cities worldwide are already implementing these KPIs.

The list of all the KPIs for SSC along with its collection methodology are contained in:​   
   All cities are invited to participate in this project and pilot these KPIs.
