London Underground: Air Pollution

Asked by Pippa HeylingsLiberal DemocratDepartment for TransportTabled Answered 21 April 2026UIN 126793

The question

To ask the Secretary of State for Transport, what discussions she has had with Transport for London on interim measures it is currently implementing on the London Underground to reduce passenger exposure, including that of children and clinically vulnerable groups, to particulate matter concentrations that substantially exceed ambient outdoor air levels.

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.
