Funded by the European Union HORIZON 2020 programme, CITYkeys developed and validated, with the aid of cities, key performance indicators and data collection procedures for the common and transparent monitoring as well as the comparability of smart city solutions across European cities (download).


The research institutes VTT (coordinator, Finland), AIT (Austria), and TNO (Netherlands) cooperated with five cities – Rotterdam, Tampere, Vienna, Zagreb and Zaragoza and EUROCITIES to define the needs, analyse existing results and develop recommendations for the use of performance indicators. Additional cities contributed to the project in order to gather as much evidence and feedback as possible about the practical use, benefits and challenges of key performance indicators (KPI) and smart city project evaluation frameworks.


The project started in February 2015 and run for 2 years. All deliverables are public and available for download on this page. For specific results, click on one of the nodes on the spidergraph below.
