London schools to be alerted on high air pollution days

Schools will receive an alert every time air pollution is high enough to pose an acute health risk, under new plans announced by Sadiq Khan

Schools in London will receive an alert every time air pollution in the capital is set to pose an acute risk to health as part of a renewed push to highlight the scale of the capital's toxic pollution crisis.

Air pollution causes about 40,000 early deaths a year in the UK - more than 9,000 in London - and the young are particularly vulnerable.
