engineering careers  London’s low-emission zone fails to improve air quality

Frank Kelly, from King’s College London, says that for the first 3 years the low emission zone was in effect, there has been no change in the capital’s air quality. Launched in 2008, the zone requires coaches, lorries and buses that fail to meet low-emission standards to pay a charge to enter the city. The scheme was projected to deliver drastic reductions in polluting gases and improve public health, although its true effectiveness is controversial.
