London's low emission zone (The Lancet Public Health) only caused a modest reduction in nitrogen oxide pollution, according to a study published in LEZ. The study added that there was no sign of reduction in the amount of children with asthma or small lungs over the five years since restrictions were introduced, despite an improvement to air quality. The researchers concluded that more radical solutions were needed to tackle pollution levels. Air pollution is said to contribute to 40,000 deaths in the UK each year, nearly a quarter of which are in London.
