The Mayor of London, Sadiq Khan, today announced he is introducing air quality alerts at bus stops, Tube stations and road-sides across the capital to notify Londoners during the worst incidents of air pollution.

The mayors has just finished an initial consultation on a comprehensive package of measures to clean-up the capital’s filthy air.
Nearly 15,000 people responded to this consultation and 79 per cent of respondents stated that they wish to receive information when air pollution is high or very high so that they can take action to protect their health and reduce its impact.

Having listened to Londoners, the Mayor has taken swift and decisive action to implement a new programme of air quality advice and alerts for the public.

From Monday, August 15, during and on the day before high and very high air pollution days, air quality alerts will be displayed at: 2,500 bus countdown signs and river pier signs across London, 140 road-side dot matrix message signs on the busiest main roads into London, with instructions to switch engines off when stationary to reduce emissions.

Electronic update signs in the entrances of all 270 London Underground stations.

Depending on the alert level and communication channel, different information and guidance will be provided including: advising people to walk, cycle or use public transport if possible to help improve air quality; to reduce strenuous activity if someone experiences symptoms; or advising asthma sufferers and other vulnerable groups that they may need to use their reliever inhaler more often.
