According to Smart Cities World, the city network EUROCITIES has launched a new guide outlining key principles for using citizen data responsibly. It was developed with real-world examples from several European cities (Bordeaux, Barcelona, Debrecen, Edinburgh, Eindhoven, Florence, Ghent, Helsinki, Manchester, Rijeka and Zaragoza). The aim is to "give guidance to European local governments on how to use data-generated knowledge to improve urban life and preserve European values through scientific, civic, social, economic and democratic progress. This includes putting in place mechanisms and practices to give citizens control over their data".
