'High' alert for air pollution issued for London as 'hottest day of the year' expected

A high air pollution alert has been issued for London as the capital prepares for what is expected to be the hottest day of the year so far.

City Hall issued the warning for Thursday after Imperial College London forecasters detected an increase in air pollution from mainland Europe.

Local sources of pollution alongside southern winds contribute to the high pollution levels.

Londoners have been advised to switch vehicle engines off when stopped and avoid burning wood or garden waste.

The Deputy Mayor of Environment and Energy, Mete Coban said: “London’s toxic air is responsible for around 4,000 premature deaths in the capital each year, which is why the Mayor has done everything in his power to tackle it.

“We are urging Londoners to look after themselves in this pollution alert, stop their engines idling, and refrain from burning wood or garden waste – all of which contribute to high levels of pollution.

"This is particularly important in order to protect those who are most vulnerable as we continue working to build a safer and greener London for all.”

City Hall issues alerts to schools and local boroughs when levels in air pollution are forecast to be moderate, high or very high.

High air pollution alerts are also displayed at public locations across London, including all bus stop countdown signs, as well as on the Underground.
