London Air Quality Shows Dramatic Improvement Following ULEZ Implementation, Study Reveals
London has experienced substantial reductions in harmful nitrogen pollutants since the Ultra Low Emission Zone launched in 2019, according to new research. The study found nitrogen dioxide levels dropped by nearly 20% within three months of implementation. Despite these gains, scientists warn that air pollution still exceeds World Health Organization guidelines.
Significant Pollution Reductions Documented
London’s air pollution has seen dramatic improvements following the introduction of the Ultra Low Emission Zone (ULEZ), according to a comprehensive study led by the University of Birmingham. The research, which analyzed data from 124 monitoring sites across the capital, indicates that harmful nitrogen pollutants have dropped substantially both within the zone and in surrounding areas.
