Air pollution in London has not breached limits for the entire year in the second week of January, an improvement on last year when limits were breached in five days.
However, it is likely that the city will still breach limits set for the whole year by the end of the month.
Reacting to the news, ClientEarth spokesperson Simon Alcock said:
“The Mayor has taken some bold and welcome steps to deal with London’s toxic air problem since coming to office. It’s far too early to celebrate, though. Londoners are still breathing illegal and harmful levels of air pollution and the Mayor’s actions need to be backed up by the national government.
“That’s why we’re returning to the High Court on 25 January – ministers must take decisive action to clean up illegal air pollution across the country.”
ClientEarth is currently taking legal action for the third time against the government over illegal and harmful levels of air pollution across the UK. The case will be heard in the High Court on 25 January.
According to the latest figures, 37 out of 43 zones across the UK have illegal levels of nitrogen dioxide (NO2). In towns and cities where levels of NO2 are illegal, the problem is caused mostly by diesel vehicles.
