Air pollution is one of the main environmental problems to be addressed by cities worldwide.
In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO, SO2 and NOx) concentrations in ambient air.
Many cities are not able of meeting the implemented EU standards for particulate matter and NO2. While European Union imposes strict limit values for PM and NO2 in air through its Directive 2008/50/EC, reduction in emissions will become costly.
The EU has been funding since 1990 Territorial Cooperation programs. These include the current Balkan-Mediterranean one featuring the AirThings initiative. Its goal is to leverage the emerging technologies through IoT (Internet of Things) for air quality monitoring. And more specifically intelligent micro-sensors providing real time pollution data through internet.
