TfL Ref: FOI-1117-2324 Thank you for your request received by Transport for London (TfL) on8 July 2023 asking for information about air quality data. Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm that we hold some of the information you require. You asked: Please provide the samples of air quality data that ULEZ is based on (and Date Range used for to evaluate that ULEZ is necessary to meet current WHO limits). The information you have requested can be accessed at the following links:

We regularly monitor dust levels on the London Underground and publish monitoring reports on our website here: https://tfl.gov.uk/corporate/publications-and-reports/environment-reports#on-this-page-3 Our monitoring has shown that dust levels on the Tube remain well below limits set by the Health and Safety Executive (HSE) and on most of our network are below the recommendations from the Institute of Occupational Medicine, which are set significantly lower. But we are not complacent and we are exploring the latest innovations to tackle the issue. We have a robust three pillar programme of work to tackle Tube dust: funding of world-leading research; cleaning and monitoring; and utilising the latest advances in innovation. Transport for London does not routinely monitor particulate emissions from its Tube ventilation outlets. Its monitoring is focused on underground air quality which is taken to assess occupational exposures. If this is not the information you are looking for, or if you are unable to access it for some reason, please do not hesitate to contact me. Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed. Yours sincerely, Eva Hextall FOI Case Officer FOI Case Management Team General Counsel
