Clean Air Day 2025 is shining a spotlight on the impact of air pollution across every stage of life. From pregnancy and childhood to working age and old age. The campaign calls on all of us to take action, no matter how small, and to demand healthier, safer environments for everyone.

Healthcare professionals are playing a key role this year. With more and more evidence emerging about the links between air pollution and major illnesses, the health sector is joining the call for action, making it clear that clean air isn’t just about climate; it’s about saving lives.

Whether you`re an individual, part of a business, school, hospital, or council, there are plenty of ways to get involved this Clean Air Day.

Everyday actions you can take:

Switch one car journey to walking, wheeling or cycling
Even one less car trip per month across the UK could cut billions of journeys and tonnes of emissions.
Turn off your engine when parked
Idling contributes significantly to poor air quality, especially outside schools and hospitals.
Use public transport or car share
Train travel produces around 80% fewer emissions than driving alone.
Talk about it
The more we raise awareness—online or in person—the more normal and urgent these conversations become.

Use your voice

Clean Air Day is about action and advocacy. Use this opportunity to write to your local councillor or MP and call for change: more investment in clean public transport, safe cycling infrastructure, and low-emission zones that protect our towns and cities.

Councils, schools and businesses can also lead the way by:

Running Clean Air Day events: school walks, no-idling zones, staff cycling challenges, or lunch & learns.
Sharing their commitment online using the hashtag #CleanAirDay.
Using free resources from Global Action Plan and the Clean Air Hub, including toolkits, posters and social media templates.

Looking into the future

Air pollution might feel like an invisible problem, but its effects are deeply visible in our health and environment. The good news is that change is possible, and it starts with collective action.

If half of short urban trips in the UK were switched to walking or cycling by 2030, we could save as much carbon as powering a city the size of Manchester for a year.

Should clean air be a national priority?
