What is the name of your initiative?
Snuffelfiets (Snifferbike)
How would you describe the main mission of your initiative?
  • Measure/monitor air quality
  • Measure personal exposure
  • Raise awareness/education


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.
Within the Snifferbike project, bikes are equipped with sensors measuring air quality. Citizens use these bikes to for instance commute to work and collect air quality data at the same time. The data is collected at a central location but can also be used by the individual users.
Who is your main audience?
  • Citizens
  • Schools
  • Universities and/or research institutes


If possible, provide the list of partners involved in the initiative.
Sodaq, Civity, WeCity, Provincie Utrecht, Provincie Zeeland, Gemeente Zwolle, Globe Nederland
How is this initiative funded?
  • Municipality programme
  • Other


Context – Other
Provinces, university
Please provide an estimation of the total budget of the initiative:
What is the status of the initiative?
What is the duration of the initiative?
1 to 5 years
How many participants (citizen scientists, volunteers, etc.) have been involved (approximately)?
500 – 1000

Would you like to share with us any additional information? (Max 300 words)
* Pay attention to privacy aspects before you start collecting the data
* Make sure to keep track of all of your sensors (who is using which sensor) and have a process in place to return a sensor if someone looses interest so that you can provide it to the next person on the waiting list
* Measuring air quality provides useful insights

Measurements and perceptions of air quality

Measurements and perceptions of air quality

Location: Paris, France

Description: The aim of the project is to improve knowledge of the levels of pollution at the heart of traffic, while testing a new network of measurements, and to understand the perception of Ile-de-France residents with regard to air quality. These innovations will make it possible to raise awareness of air quality in Ile-de-France, and ultimately to identify the levers of commitment of Ile-de-France residents to reduce air pollution.

Measure Together (Samen Meten)

Measure Together (Samen Meten)

Location: Utrecht, Netherlands

Description: Samen Meten is an infrastructure for data and knowledge sharing for citizen scientists interested in air quality. We provide a platform where citizens can find their own data and the data of others. In addition, the data can be analysed via the 'Analyse together tool'. New citizen scientists can also find information on how and where to start measuring air quality. Currently also data on noise and water quality is added.

Location: Bilbao, Spain

Description: The H2020 SOCIO-BEE project aims to encourage citizens to take an active role in the fight against climate change through citizen science using disruptive technologies such as drones and wearables articulated by a framework called AcadeMe. More specifically, Socio-Bee aims to involve different segments of citizens (young people under 16 years of age, older adults over 65 years, and people who commute by car or through public transport in large cities or suburbs) in different scientific endeavors..
