Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, whether her Department holds data on air quality for (a) Putney constituency and (b) Wandsworth borough for each of the last five years.

The Mayor of London is responsible for air quality in the capital and has reserve powers under Part IV of the Environment Act 1995 to reflect this. Local authorities in London are required to review and assess local air quality and report their data to the Mayor.

In addition, the London Air Quality Network provides data on automatic air quality monitoring in London to the public.
