My Lords, it is well understood that poor quality air produces many incidences of cardiovascular and respiratory diseases, as well as cancer. Does it not make sense for this to be a core area of health policy and a positive way to close the gap of £30 billion which is expected in the NHS budget by 2021?
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.
