London's clean air zone boosts children's lung growth

In London, the introduction of the Ultra Low Emission Zone (ULEZ) aimed to reduce traffic pollution. A study found that this initiative led to faster lung growth in children, with significant improvements in lung function observed. The research compared children in central London with those in Luton, revealing that pollution levels fell more rapidly in London. As a result, the proportion of children with impaired lung function decreased, highlighting the health benefits of improved air quality.
