Ulez expansion three years on: How London's pollution gap persists

Three years after the expansion of London’s Ultra Low Emission Zone (Ulez), the pollution “gap” remains, according to the BBC. The story highlights the case of Rosamund Adoo-Kissi-Debrah, whose nine-year-old daughter Ella died of an asthma attack in 2013. After a medical report linked Ella’s illness to illegal levels of air pollution near their home, an inquest was opened. Ella became the first person in the UK whose death certificate listed air pollution. The coroner recorded a “failure” to reduce nitrogen dioxide below EU and domestic limits. Ulez’s initial improvements are acknowledged, but Adoo-Kissi-Debrah says more action is needed.
