The European Environment Agency (EUA) - which, as an agency of the European Union, has the task of providing sound, independent information on the environment to those involved in the development, adoption, implementation and evaluation of environmental policy, and therefore to the general public- has developed the European City Air Viewer, a tool to compare the air quality of European cities with each other in 2019 and 2020.
Cities are ranked from cleanest to most polluted based on average particulate matter (PM2.5) levels over the last two calendar years (2019 +2020).
The example of the digital and science city of Darmstadt in particular shows how important investments in the digital infrastructure of the city or region can pay off. With the support of [ui!] Urban Lighting Innovations, 32 environmental sensors were installed on the existing street lighting infrastructure and connected to the new central data platform of the city of Darmstadt provided by the [ui!] Urban Software Institute.
The data collected in this way will be analyzed and processed into knowledge that will help those responsible to assess, adjust or, if necessary, improve the effects of measures to improve air quality. By means of a higher number of environmental sensor systems distributed over the entire city area, a holistic picture of the current environmental situation of Darmstadt can be created in real-time and used to make and control the necessary decisions. The more and the better the quality of data, the more likely it is to make the right decision to improve urban air quality.
Another lighthouse project, which will hopefully be implemented in many other communities and regions to improve the air quality in the entire country for all citizens.
