In the CitizAir project, KTH Royal Institute of Technology, SLB-analys and VA (Public & Science) are collaborating to visualise air pollution data together with Stockholm residents. Anyone traveling around Stockholm will be able to learn which route around the city would be the healthiest, directly via their mobile phones and from billboards at key city locations. The aim is to develop an interactive and immersive augmented reality experience that combines pollution data, public screens in the city with an app on people’s phones.

The visualisations will be developed together with citizens of Stockholm to ensure their interests and needs are taken into account. The project started in late 2021, and by 2024 Stockholm’s air quality is planned to be interactively displayed on screens.

The two major air pollutants affecting human health are nitrogen dioxide and micro particles (PM10). That is why levels of these pollutants will be displayed and visualised locally, in the same area as the levels are being measured. The data will also be available to download to smartphones by interacting with the screens. In this way, citizens can make informed decisions about which roads or means of transportation to choose. In the longer run, they will also be better prepared to discuss air quality and to affect environmental decisions and policies

Everything that is developed within CitizAir will be published openly and be accessible and usable worldwide. The project will therefore contribute to the sustainable development of cities, and consequently to several of the global Sustainable Development Goals. CitizAir is financed by Formas, the Swedish research council for sustainable development.
