CHILL (Children’s Health in London and Luton)

Air pollution stunts children's lung growth and damages brain development. London's Ultra Low Emission Zone (ULEZ) was introduced in 2019 to reduce air pollution caused by traffic in Central London. In August 2023, it was extended to span all London boroughs.

Children’s Health in London and Luton (CHILL) aims to independently evaluate whether the Ultra Low Emission zone is effective at reducing air pollution, and improving children's lung growth and respiratory health.
