Air quality warning signs to be displayed across London

Air quality alerts will be installed from next week across London as the mayor of London attempts to educate the capital about air pollution.
During and on the day before 'high and very high' pollution days, air quality warnings will be displayed on 2500 bus countdown signs, on 140 roadside signs on the busiest main roads into London and electronic update signs will be installed at the entrances of all 270 London Underground stations.
The signs leading into London will also provide instructions to switch off engines when stationary in order to reduce emissions. Depending on the alert level, different information and guidance will be provided including advising people to walk, cycle or use public transport to help improve air quality, adding that people should reduce strenuous activity and suggesting that asthma sufferers and other vulnerable groups may need to use their reliever inhaler more often.
Three-day air quality forecasts will also appear on the signs, while the mayor of London, Sadiq Khan, will use his social media channels to make people aware of air quality incidents.
Khan said the roll-out of these signs follows on from a recent consultation where 79% of respondents said they wanted to know when air pollution is high or very high.
"Unlike my predecessor, I believe that Londoners have a right to know about the quality of the air that they breathe. These new alerts will allow them to take precautions and help them plan ahead to avoid the worst instances of air pollution," Khan said. "I am doing everything within my power as mayor to put the health of Londoners first. I hope that these alerts will become less and less frequent as we take steps to make our already great city a cleaner place to live, work and study in."
