The Air We Breathe: Lessons From London's Ultra Low Emission Zone In 2019, London introduced the Ultra Low Emission Zone (Ulez), a pioneering policy aimed at reducing air pollution in the city.
Researchers from Queen Mary University of London recently published a study that has shed new light on the effects of Ulez on children's lung development.
The study followed over 3,400 primary school children in London and Luton, comparing their lung growth and capacity before and after the introduction of Ulez.
