Reducing air pollution improves health outcomes for children.
According to a study published in The Lancet, scientists say they have been "stunned" by how quickly young children's lungs began to recover and grow after pollution protections were brought in where they lived.
London created an "Ultra Low Emission Zone (Ulez)" in 2019. Researchers tested lungs of young elementary-aged children in London before the "Ulez" took effect and found they "were smaller in capacity than those in Luton, [another city] which is less polluted than London but has a similar mix of pollutants.
After 4 years of implementing the Ulez, researchers tested the lungs of the London kids again & found "the children's lung capacity reached near identical levels" to the children in the less polluted city. This shows an ambitious clean air zone can drive pollution levels down, rapidly restoring children's stunted lung growth.

Children's lung capacity caught up with their peers in less polluted areas once a clean air zone came in, a study shows.
