Air pollution poses a serious threat to children's health in the UK, contributing to a range of adverse health outcomes and premature mortality. This updated position statement reviews the latest evidence, now including the impact of indoor air pollution on children. With pollutants from both outdoor and indoor environments presenting serious risks to the health and development of children and young people, there is an urgent need for comprehensive policy measures to safeguard their future.

We strongly support national policies and legislation that aim to improve indoor and outdoor air quality. We encourage child health professionals to share information with colleagues and patients, and use their voices to advocate for clean air. We recognise that air pollution is a global issue requiring international cooperation. For this statement our messages and recommendations are specific to the UK.
