Jeden Tag atmet jeder rund 20.000 Mal ein und aus - gleichzeitig belasten Industrien, Verbrennungsmotoren und Schornsteine unsere Luft ständig. Eine städtische Luftqualitätsplattform ist ein Netzwerk zur Erfassung der Luftqualität, das den Bürgern den Zugang zu hyperlokalen Daten über lokale Emissionen wie Ozon, Partikel, Stickoxide, Kohlenmonoxid und Ammoniak ermöglicht. Darüber hinaus können auch Daten über die Luftqualität, das Wetter oder den Verkehr hinzugefügt werden.


The main goal of the Urban Air Quality Plaform is to raise awereness on the Urban Air Quality. Thereby, it intends to initiate actions fighting pollution. Whereas some benefits are likely to be fulfiled with a basic implementation of the solution, the fulfilment of the potential benefits depends on the functions implemented in a specific project.

How air quality data is visualised is rather straightforward, through a dashboard in a web browser platform or mobile app. However, what truly differs is the methods of data collection and processing. The following variants give an overview of four different data collecting methods.    


Low-cost air quality sensors are becoming widely used for broad urban applications, as they offer air pollution monitoring at a lower cost than conventional methods, thus allowing a higher density deployment.

Metal oxide sensors are the most affordable in the market, in 2020, the approximate cost of such system ranged between 1,000 – 5,000 EUR. With higher sensor cost, the response time and sensitivity to temperature and humidity variations improves.

Therefore, a low-cost sensor deployment must be accompanied by a machine learning algorithm that can reproduce sensor responses at different measurement sites and conditions. Due to the influence of meteorological parameters on a sensor signal, simple correction and/or calibration is not always possible.


Participatory sensing is the action of citizens voluntarily using their computational devices to capture and share sensed data from their surrounding environments in order to monitor and analyse air quality. Recent technological advances in sensor technology have allowed for the creation of portable as well as visually appealing sensors that can be carried or be installed in backyards. These sensors can both provide air quality data to a central UAQP and inform citizens of the surrounding air quality through an app.


Verwendung mobiler Daten zur Berechnung der Luftverschmutzung

Da die zunehmende Umweltverschmutzung zu einem der größten Probleme der Städte wird, müssen sie genaue Daten zur Luftqualität sammeln, bevor sie konkrete Maßnahmen ergreifen. In diesem Projekt verwendet Telefonica Next anonymisierte Mobilfunkdaten zur Berechnung der Luftverschmutzung.

Mobile Luftreinhaltung in Bussen

Die städtische Luftverschmutzung ist hyper-lokal. Die tödliche Luftverschmutzung variiert mehr als 8x innerhalb von 200 Metern, was sich jedoch nicht auf den aktuellen Luftverschmutzungskarten widerspiegelt. AirVeraCity liefert den Menschen verwertbare Informationen zur Luftqualität.


While ground sensing can accurately measure air pollutant concentration, its coverage is limited to the deployment of sensors. Therefore, researchers in Europe, have developed a software that uses fine spatial resolution sensors to determine air quality at an urban level. This is achieved through a radiometric comparison of satellite imagery of a clear day to a polluted day. This provides a relative quantitative scale of air pollution, which is used in conjunction with ground-based monitors to develop spatially resolved maps of air pollution (Engel-Cox et. al, 2012)

The European Space Agency is nowadays the leading organisation in fostering remote sensing satellite imagery for the improvement of air quality. Projects such as Copernicus provide satellite information to help service providers, public authorities and other international organisations improve European citizens' quality of life.


Implementation Facts

Average Implementation Time: 0,1 - 1 years

Initial Investment Amount: less than 50,000 € for an urban district

Market Overview

According to a review by Business Wire, amidst the COVID-19 crisis, the global market for Air Quality Monitoring Systems is estimated at 3.47 Billion EUR. Similarly, it is projected to reach a revised size of 4.63 Billion EUR by 2027, growing at a CAGR of 4.4%.

The global air quality monitoring market is divided into indoor and outdoor monitoring. Urban air quality systems are classified as outdoor monitoring systems. These can be further categoriszed into fixed, portable, dust, and particulate monitors and air quality monitoring stations. 


Current technological advances in air quality sensors significantly decreased both fixed and variable costs of UAQPsurban air quality platforms.  Fixed costs include the software, consisting of its communication API and web graphical user interface. Variable costs include calibration and maintenance, among others.

New technologies remove most of the need for local maintenance and calibration, moving these functions to a cloud service. Therefore, operating costs of these kinds of platforms include cloud-based computerized maintenance management systems.

Achieving citizen awareness and understanding of urban air quality systems is necessary for any UAQP implementation. Therefore, fixed costs must include a citizen portals and citizen participation campaigns.

Impacts of Air Pollution:

1) Global Warming

2) According to research co-authored by UCL, an estimated 1 in 5 deaths every year can be attributed to fossil fuel pollution and in 2018, approximate 8.7 million people died due to fossil fuel emissions alone. Figure from which 21.5 % is attributed to particulate matter. Figure 1 illustrates the death distribution as a cause of air pollution. 

Figure 1. Average outdoor PM2.5 pollution and total air pollution deaths by region in 2013 (World Bank, 2013)

3) In 2016, the WHO declared that 92 percent of the global population lived in areas where the pollution exceeded the world health organization’s air quality guidelines. 

4) The effects of air quality on people was estimated in 2013 to cost the global economy approximately  190 billion EUR (World Bank, 2013).

Causes of indoor air pollution:

As mentioned, anthropogenic sources are the main contributors to air pollutants. However, air pollution can also be caused by natural sources such as volcanic activity (releasing mainly SO2, CO2, and HF), sandstorms like the Saharan Dust, and ozone produced by the reaction of sunlight with oxygen. Nonetheless, anthropogenic sources are emitted with a much higher rate and density.

Anthropogenic sources can be classified into mobile, stationary and area sources. Mobile sources involve emissions produced by transportation, such as vehicles, maritime vessels and trains. Air pollutants in exhaust gases are generated by incomplete combustion of fuel. Carbon monoxide and unburned fuel are the main exhaust gases produced by gasoline engines.

Stationary sources are power plants, industrial activity and oil refineries. The effect of these is greater when located within the urban area of a city. The energy sources with the highest emission factor are lignite hard coal, which is the reason why there is a global effort to phase out coal as an energy source.

Finally, area sources can be appointed to agricultural and human activity. Agricultural emissions are usually underestimated; however, being that ammonia NH3 and methane CH4 are the main air pollutants, their impact is severe. Methane, for example, has a global warming potential 28 times higher than carbon dioxide.

Treibende Faktoren

Government Initiatives

  • UK Clean Air Strategy: This strategy sets out the comprehensive action that is required from all parts across the UK government and society to meet environmental goals. The 2019 legislation outlines a strong and coherent framework for action to tackle air pollution.
  • European Green Deal: The EU Green Deal under its policy area “Eliminating Pollution” has reinforced among others its support to local authorities to achieve cleaner air for its citizens. It will also propose to strengthen provisions on monitoring, modelling, and air quality plans to help local authorities achieve cleaner air.

Rechtliche Anforderungen


European Union policy on air quality aims to develop and implement appropriate instruments to improve air quality. Therefore, European States have to divide their territory into several zones and agglomerations. In these zones and agglomerations, the Member States need to undertake assessments of air pollution levels using measurements, modelling, and other empirical techniques – and report air quality data to the European Commission accordingly.

The EC has set air pollutants concentration limits enforcing member states to address the sources responsibly. In addition, information on air quality should be disseminated to the public. (European Commission, 2018)

  • Ambient Air Quality Directive 2008/50/EC: The directive provides the current framework for the control of ambient concentrations of air pollution in the EU. The control of emissions from mobile sources, improving fuel quality, and promoting and integrating environmental protection requirements into the transport and energy sector are part of these aims.
  • Directive 2015/1480/EC:Establishes the rules concerning reference methods, data validation, and location sampling points for the assessment of ambient air quality
  • Directive 2010/75/EU:On industrial emissions
  • Directive/2284/EU: On the reduction of national emissions of certain atmospheric pollutants. This directive enforces the reduction of air pollutants such as SOx, NOx, and VOCs.
  • German Federal Emission Control Act – BImSchV 39th: The procedure for determining urban emission sources in Germany is defined in the 39th Ordinance of the Federal Immission Control Act (39th BImSchV). This federal law is based on the EU Directive 2008/50/EC.
