Local Air Quality Breaches

Did the Committee arrive at an overall ballpark figure as to the cost to society as a whole from air pollution? I think you, Chair, and I were on an unprecedented joint transport, local government and environmental committee two or three years back that looked into air pollution and I think we arrived at a figure in the ballpark of £20 billion a year in terms of health and other costs to the country. Those figures are always quite useful, as I am sure my hon. Friend the Member for Hackney South and Shoreditch (Dame Meg Hillier) agrees, when making arguments for the Treasury about the cost-benefit of taking real, meaningful action on an issue such as air pollution.
