My noble friend makes an important point. Defra works closely with the Department of Health and Public Health England and its advisers, as well as the Committee on the Medical Effects of Air Pollutants. We have daily air quality forecasts which provide accompanying health messages because a combined cross-departmental effort is required to tackle this problem.
My Lords, in her response to the question put by my noble friend Lord Dubs, the noble Baroness referred to an expenditure of £2 billion to improve air quality. Is that £2 billion a national figure or is that the money to be spent just in London?
The sum of £2 billion is predominantly for London because I am answering questions on London and the mayor of London’s programme. Defra has an air quality grant programme of £1 million and there are various other programmes. In this context, however, we are talking about what is being done to improve London’s air.
