Our Ref:         FOI-0582-2021

Thank you for your request received on 8 July 2020 asking for information about pollution level readings.
 
Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy.
 
We can confirm that we do not hold the specific information you have requested.
 
London’s air quality is constantly monitored at over 120 different locations. These sites are operated and funded by the London boroughs, Transport for London and Heathrow Airport. Data from these sites is publicly available in real time from the two organisations they contract to undertake the monitoring:
           
 . Imperial College London record real time and historical monitoring data for the majority of boroughs and make the data available through the London Air website at www.londonair.org.uk.
 . Ricardo Energy and Environment record real time and historical monitoring data for the remaining boroughs and make the data available from the Air Quality England website at www.airqualityengland.co.uk
 
This data covers all of London and is regularly updated. This includes monitoring sites in and around central London and specifically some locations where we have implemented Streetspace initiatives.
 
The latest data from these monitoring sites confirms that roadside pollution across central, inner and outer London remains well below both 2019 levels and pre-Covid lockdown levels. We continue to observe the readings from these sites and will report later in the year on our understanding and projections for longer term impact.
 
The Greater London Authority are currently developing proposals for undertaking air quality monitoring at a number of Streetspace interventions. This data and subsequent analysis will be made publicly available. 
 
The impact of current circumstances on TfL’s resources means we are not able to answer requests readily and we ask that you please do not make a request to us at present.
 
Answering requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. In any event, please note that our response time will be affected by the current situation.
 
Please see the attached information sheet for details of your right to appeal.

Yours sincerely
