How would you describe the main mission of your initiative?• Measure/monitor air quality
• Measure personal exposure
• Smart/sustainable mobility
• Raise awareness/education
• Commercialize air quality sensors
• Air quality modelling

Please provide a short description of your initiative (What is being done? Who is participating? What are your main goals?) This text will appear on the main page.CurieuzenAir is a scientific research project that aimed to map the air quality across the whole of Brussels. Citizens, schools and companies joined the largest citizen science project ever carried out in Brussels. For one month and at 3000 different locations, citizens attached a sensor panel with two measuring tubes to a window to measure the concentration of nitrogen dioxide (NO2) in the outdoor air. The results expose the difference in air quality across the city with unprecedented spatial detail.

Who is your main audience?• Citizens

Other Initiatives

Increasing Community Resilience in Climate Adaptation Process Project

Location: İstanbul, Türkiye

Description: With the establishment of the “Kadıköy Municipality Environmental Monitoring and Early Warning System”; We aim to create a resilient structure guided/supported by the local government with participation at the neighborhood scale and to raise awareness about climate change. Data is transferred to the "Kadıköy Municipality Environmental Monitoring and Early Warning System" for the detection of emergencies such as air pollution and heat wave/heat island effect that adversely affect public health, especially the fragile population.

List of parameters measured: PM2.5, PM10, Temperature, Humidity

AirQon

Location: Breda, Netherlands

Description: AirQon is initiative that makes us of EV-cars instead of dieselgenerators specially to provide festivals with sustainable energy. due to all the problems during COVID 19 the pilot was broadend to the construction branche

List of parameters measured: PM2.5, PM10, Black Carbon, UFPs (Ultrafine particles)

CitieS-Health

Location: Barcelona, Spain

Description: CitieS-Health aimed to put citizens’ concerns at the heart of research agenda on environmental epidemiology by tackling health issues that concern them. Citizens along with scientists in 5 cities in Europe co-designed and implemented epidemiological studies to explore how their living environment is affecting their health. The Barcelona CitieS-Health pilot project was a scientific study co-created by the citizens who explores how air quality, green spaces and noise affect the sleep, the attention span and stress.

List of parameters measured: NO2
