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

Increasing Community Resilience in Climate Adaptation Process Project

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.

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.
