What is #LetSchoolsBreathe?

Monitor, inform, educate.

#LetSchoolsBreathe is our campaign to install air quality sensors in the UK’s most polluted schools.

Good air quality is crucial to children’s health, and the first step towards improving air quality is knowledge. This issue has come to the forefront of political discussion, especially in the wake of the recent pandemic and the landmark case in which air pollution was legally deemed to have caused the death of Ella Kissi-Debrah, a nine year old girl suffering from asthma. We are offering schools the opportunity to learn more about the air that students breathe on a daily basis.

The offer is simple: an Airly sensor which measures outdoor air quality - particulate matter (PM) and gases - for a 6 month period, completely free of charge.

The sensor will monitor outdoor levels of PM and dangerous pollutant gases (like NO2, which is particularly harmful for children) 24 hours a day in the immediate vicinity of your school, and any interested parties, such as parents, local community or officials, will be able to view this data for free on our app or map (airly.org/map/en). Airly can also integrate the sensor data directly into your website platform via a widget.

Our aim

Throughout the 6 months, we aim to help engage parents, the community and your local council with essential knowledge on the air your pupils breathe, and crucially how it varies by time of day. This information will make a compelling case to your local councillors to implement measures that improve air quality, whether this is through traffic legislation banning cars during times when students are walking along roads or clean air funding to pursue projects that actively improve the air at your school.
