A study has linked London's ultra-low emission zone (ULEZ) to improved lung growth in children residing within its boundaries.
Researchers compared lung function development in children living inside the zone with those living outside it over the same period.
The analysis found that children inside the ULEZ experienced measurably better lung function growth.
The ULEZ, which charges older, more polluting vehicles to enter designated areas, has reduced traffic-related air pollutants such as nitrogen dioxide.
The study associates this reduction in air pollution exposure with the observed improvement in children's respiratory development.
The research design accounted for confounding factors to isolate the effect of the policy on health outcomes.
The findings add to evidence that traffic restriction zones can yield direct pediatric health benefits.
Further research will track whether these early gains persist into adolescence and adulthood.
