Asked Of: 
The Mayor


A peak reading of 102.56 mg/m3 was obtained in North End Road in Slade Green in December 2016, but there is no permanent NO2 monitoring station there. Will you install a permanent NO2 monitoring station on North End Road in Slade Green, where pollution levels are highest, in order to assist your drive to clean up London's air?

Operation and maintenance of air pollution monitoring stations is the responsibility of the London boroughs and Defra.  I have made maintaining the current air quality network one of the responsibilities of London boroughs within my statutory London Local Air Quality Management framework.

As permanent automatic monitoring is very expensive, the monitoring network is used to complement and validate the extensive modelling I provide through the London Atmospheric Emissions Inventory, as opposed to providing full coverage across all polluted areas of London.

I have several new initiatives to support a roll out of more lower cost monitors.  I have already announced that London will pilot a new air quality sensor network which will deliver up to 1,000 new monitoring sites. The pilot project may also feature mobile monitoring devices, so data will potentially be available from hundreds of thousands of locations across the city. As part of this project the monitoring requirements across London will be fully assessed on a strategic basis, and it may be that there will be an opportunity to install a sensor in Slade Green.

In my draft London Environment Strategy I also committed to publish guidance to assist individuals and community groups to undertake their own effective local monitoring.
