Alan Andrews, a lawyer at ClientEarth — the group that successfully sued the government — said: It is absolutely essential that he now delivers on his promises and that the national government back him to the hilt.
A spokesman for the mayor said: The mix of these toxic air pollution levels with freezing temperatures pose a serious risk to people with lung conditions and can affect all of our health.
Putney High Street, where high buildings trap pollution, was the worst. The Kings College data also shows Putney High Street broke hourly limits 1, times invastly exceeding the permitted 18 breaches.
Brixton Road broke the hourly limit times. This was down from inbut illegal levels of the toxic gas remain a serious issue, with the government estimating it causes 23, early deaths a year.
The government must produce a new draft national plan by April and ClientEarth said this must include clean air zones in many areas to stop the dirtiest diesel cars entering pollution hotspots.
Both a national network of clean air zones and tax changes were proposed within government as part of its last plan, but were rejected by the Treasury. A government spokesperson said: In December, Paris, Madrid, Athens and Mexico City pledged to ban polluting diesel cars from their centres by and a number of cities outside the UK have already taken action such as banning cars on specific days or making public transport free.
Jenny Bates, at Friends of the Earth, said: Road traffic is the biggest culprit — and diesel is the worst. This is why the government must take much bolder and quicker action including planning to phase out diesel by How UK cities compare on nitrogen dioxide exceedance Topics.Transport.
