London's low-emission zone fails to improve air quality

Description

London's campaign to reduce the city's air pollution has not been as successful as hoped. The scheme was launched in 2008 and its aim was to improve the air quality. Earlier this year, London's mayor confirmed plans to launch an ultra-low emission zone to enforce stricter pollution standards on vehicles. Professor Frank Kelly, Analytical Environmental Health, said: If you really want to achieve an improvement in air quality, these vehicles should be banned.
