Best practice in the general use of data in a city

This chapter gives a "bird's eye view" of a variety of examples of how some of the "EU CITIES MISSION's 100 climate neutral and smart cities by 2030" are already using data from a wide variety of sources. They collectively will bring a wide range of experiences to ensure that the identified good practices in data usage might be shared and built upon, in the drive to make data work to drive forward the climate-neutral agenda.1 The examples come from a wide range of application areas and reflect the variety of the emerging data spaces, with the majority coming from the "100 climate-neutral cities". Whilst useful in its own right to be able to see the variety of uses data is being put to in a city, to stimulate ideas and potential replication elsewhere, the main purpose is for it to be used as a building block. The following chapter will concentrate on how cities have used personal data in the process of running their city. But in addition to providing these examples, we will also try to indicate how, by adding personal data to the data currently being used in the cases described in this chapter, added value might be demonstrated.
