Stockholm air quality at your fingertips

Which route around  the city would be healthiest for your respiratory system right now? Anyone traveling around Stockholm will be able to learn that directly via their mobile phones and from billboards at key city locations. In the CitizAir project, KTH, SLB-analys and VA (Public & Science) are collaborating to visualise air pollution data together with Stockholm residents.

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,” explained Dr. Mario Romero, Associate Professor at KTH Royal Institute of Technology and project manager for CitizAir.

SLB-analys is a unit within the City of Stockholm’s Environmental Department that monitors the air and noise environment. Their open data will be made more accessible through the project.

“The levels of air pollution vary a lot in Stockholm, both in terms of geography and over time. Therefore, it can be very interesting for citizens as well as politicians to have access to this data in an interactive manner,” said Dr. Magnuz Engardt at SLB-analys.

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 project started in late 2021, and by 2024 Stockholm’s air quality is planned to be interactively displayed on screens.

“The visualisations will be developed together with citizens of Stockholm to ensure their interests and needs are taken into account. We want to engage and involve those who live or spend time in Stockholm, in their local environment,” said Maria Hagardt, Project Manager at VA (Public & Science) that will work on the communication and dialogue parts of the project with Stockholmers.

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.
