Every breath our children take should be safe, but across the UK, toxic air is damaging young lungs before they've even had a chance to develop. Air pollution is linked to asthma, stunted lung growth, and thousands of premature deaths every year, and it hits the youngest and most vulnerable hardest.

Mums for Lungs is a grassroots movement of people who care about clean air, campaigning for a world where no child has to grow up breathing dirty air. We started as a small group of mums on maternity leave and we've grown into a nationwide network campaigning on School Streets, diesel emissions, wood burning and more.

We know that politicians move when they hear from enough people. That's why we write directly to MPs, ministers and local councils, and it's why we need you. Every letter you sign adds another voice demanding cleaner air for our kids.
