TfL Ref: 3118-2223
Thank you for your request received by Transport for London (TfL) on 21 February 2023 asking for information about the ULEZ expansion.
Your request has been considered in accordance with the requirements of the Environmental Information Regulations (EIR) and our information access policy. You asked: I understand the purpose of ULEZ expansion to include the outer London boroughs is to improve air quality in London. What is the estimate number of lives that will be saved by this expansion and who is making these estimates? I can't find this information anywhere.
The air quality and health outcomes of the London-wide ULEZ are set out in section 6.2 of the Integrated Impact Assessment (IIA). Table 6-2 and 6-3 of the IIA provide the estimated reduction in life years lost as a result of London-wide ULEZ.
Detailed information on the methodology behind assessing life years lost and attributable deaths can be found in the report ‘Health burden of air pollution in London’ produced by Imperial College https://www.london.gov.uk/programmes-and-strategies/environment-and-climate-change/environment-publications/health-burden-air-pollution-london. Burden calculations are a snapshot of the burden in one specific year. TfL and GLA review the burden calculations periodically, particularly taking account of updated advice from COMEAP and other health expert views, and any updated burden estimates will be made available in the future.
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.
