The introduction of London’s first clean air zone 15 years ago has significantly improved air quality, according to new analysis.

Academics at the University of Bath said the launch of London’s low emission zone (Lez) in 2008 and subsequent ultra low emission zone (Ulez) from 2019 has significantly improved air quality.
