What is the name of your initiative?Smart Citizen

How would you describe the main mission of your initiative?Measure/monitor air quality, Raise awareness/education, Commercialize air quality sensors

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.Smart Citizen empowers communities to better understand their environment by collecting, understanding, and sharing environmental data. It provides tools at different technical levels for raising awareness, and creating empowerment through environmental data. The Smart Citizen sensor portfolio aims to create a boilerplate for individuals and communities with different sensing expertise levels in a modular, expandable and intuitive way.

Who is your main audience?Citizen, Schools, Other

Audience – OtherUniversities and research institutions

How is this initiative funded?Other

Please provide an estimation of the total budget of the initiative (in €):100 000€ to 500 000€

How many participants (citizen scientists, volunteers, etc.) have been involved (approximately)?500 – 1000

Window open or window closed? Increase a healthy surrouding

Window open or window closed? Increase a healthy surrouding

Location: Nijmegen, Netherlands

Description: By measuring inside and outside homes or offices, citizens get a clear overview what the air quality is in their living environment. By looking at the results, one can adjust its behaviour, to increase a healthy surrouding. The detectors are provided in the project to for example ten citizens. During workshops they share insides and knowledge they gained. When is the best moment to open the window? For municipalities, it can optional be combined with wood burning courses.

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

Citizen Urban Health Laboratory

Citizen Urban Health Laboratory

Location: Barcelona, Spain

Description: The Urban Health Lab is a collaborative space for experimentation, learning and practice to foster community participation in building more resilient, healthy, sustainable and inclusive neighbourhoods. The lab aims to create communities of learning and practice, working collectively to identify needs, problems and interests, and to foster creative ideas that improve neighbourhood conditions through experimentation, shared knowledge and scientific culture.

Black CarbonHumidityTemperature


Location: Saint-Josse-ten-Noode, Belgium

Description: CAIRGOBIKE is designed to improve air quality in the Brussels Capital Region (BCR) by accelerating a modal shift from car/van to cargo bike to transport children, deliver goods and services through an integrated ecosystem of complementary nudging strategies. This innovative ecosystem will convert citizens and professionals to cargo bike use, ease the access to cargo bikes and create parking facilities. User community (citizens/businesses and non-profit) will be directly involved in air quality measurement and communication.
