What is the name of your initiative?xAire

How would you describe the main mission of your initiative?Measure/monitor air quality, Measure personal exposure, Raise awareness/education, Advocate for air quality policies, Environmental justice, 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.xAire represents a large-scale monthly air quality monitoring in Barcelona and it has been replicated in Venice. It is an unprecedented citizen science project that involves schools and families to both: collect new geographically accurate data on air quality, and to empower themselves to present them rigorously in front of the City Council. With the support of the Consorci d’Educació de Barcelona, 18 public primary schools from the 10 districts of the city participate in the action.

Who is your main audience?Citizens, Schools, Non- Governmental Organisations, Cities, Universities and/or research institutes

If possible, provide the list of partners involved in the initiative.xAire was born from the “Estació Ciutat” community project, led by artist and engineer Natalie Jeremijenko, curated by Josep Perelló and directed by Amanda Masha-Caminals. It is part of the framework of the exhibition “After the end of the world”, organized by the CCCB. In collaboration with: DKV, 4sfera Innova, Mobile Week Barcelona, Institut de Salut Global de Barcelona (ISGlobal), Mapping for Change, 5th Science Congress of the Consorci d’Educació de Barcelona, Centre de Cultura Contemporània de Barcelona (CCCB), through the “Estació Ciutat” project.
