London Underground: Air Pollution

Asked by Pippa HeylingsLiberal DemocratDepartment for TransportTabled Answered 21 April 2026UIN 126791

The question

To ask the Secretary of State for Transport, with reference to the Committee on the Medical Effects of Air Pollutants’ recommendation in 2019 for a comprehensive toxicological study of particulate matter on the London Underground, what the current status of that study is.

Answered by Simon Lightwood

Transport in London is devolved to the Mayor of London and Transport for London (TfL). The Department has regular discussions with TfL on a range of issues, however, the management of air quality on the London Underground is a matter solely for them. I would suggest that you contact the Mayor and TfL directly regarding this issue.
