Detailed description (English): ConBici, through its Health and Environment Area, is once again promoting the action To School Without Smoke. This initiative highlights the benefits of active and sustainable mobility by comparing air quality around schools on days with and without traffic. The project is based on the citizen science methodology developed within Cycling with Clean Air and aims to raise awareness of the health risks of car-based school mobility.
With the collaboration of Murcia en Bici and other volunteer groups, as well as local schools such as CEIP La Arboleda (Santiago y Zaraiche, Murcia) and its parents’ associations, the action will measure fine particle pollution (PM2.5) with the support of ConBici’s air quality monitors. Volunteers will help schools carry out the measurements, while ConBici provides technical guidance, training activities, and communication support.
The measurements will be taken on two consecutive mornings, coinciding with school entry: one representative of a traffic-free day (Sunday 21/09/25) and one of a typical school day with traffic (Monday 22/09/25). Results will illustrate the clear impact of motor traffic on children’s exposure to pollution.
Awareness-raising activities will be organized in schools before, during, or after European Mobility Week, reinforcing the message that walking and cycling are healthier, safer, and more sustainable ways to get to school. This joint action across several Spanish cities seeks to make children’s right to breathe clean air visible and undeniable.

ConBici, a través de su Área de Salud y Medio Ambiente, impulsa de nuevo la acción Al cole sin humos. Esta iniciativa pone de relieve los beneficios de la movilidad activa y sostenible mediante la comparación de la calidad del aire en los entornos escolares en días con y sin tráfico. El proyecto se apoya en la metodología de ciencia ciudadana desarrollada en Cycling with Clean Air y busca concienciar sobre los riesgos para la salud asociados a la movilidad escolar en coche.
Con la colaboración de Murcia en Bici y otros grupos de voluntariado, así como de centros escolares como el CEIP La Arboleda (Santiago y Zaraiche, Murcia) y su AMPAs, la acción medirá la contaminación por partículas finas (PM2.5) con el apoyo de los medidores de calidad del aire de ConBici. El voluntariado acompañará a los colegios en la realización de las mediciones, mientras que ConBici ofrecerá apoyo técnico, actividades de formación y soporte en la comunicación.
Las mediciones se realizarán en dos mañanas consecutivas coincidiendo con la entrada a clase: una representativa de un día sin tráfico (domingo 21/09/25) y otra de un día lectivo habitual con tráfico (lunes 22/09/25). Los resultados mostrarán el impacto directo del tráfico motorizado en la exposición de los niños a la contaminación.
En los colegios se organizarán actividades de sensibilización antes, durante o después de la Semana Europea de la Movilidad, reforzando el mensaje de que caminar y pedalear son formas más saludables, seguras y sostenibles de llegar a la escuela.
Target group(s): - School children
- Parents and families

Objectives: - Raise awareness in school communities about the impact of motor traffic on air quality and children’s health.
- Promote active mobility (walking and cycling) as a healthy, safe, and sustainable alternative to cars.
- Measure and compare fine particle pollution (PM2.5) around schools on traffic and non-traffic days.
- Engage families, students, and teachers in a collaborative citizen science action.
- Highlight children’s right to breathe clean air and enjoy safer school environments.
Partner: ConBici and 17 partner associations (NGOS) who collaborate with ConBici to implement the
"Pollution free to school” action in schools within their respective cities.
