Indoor and outdoor air pollution 'claiming at least 40,000 UK lives a year'

Report finds air pollution inside and outside the home is costing 20bn a year as well as causing tens of thousands of deaths

Air pollution both inside and outside the home causes at least 40,000 deaths a year in the UK, according to new report, which estimates the cost of the damage at 20bn.

The major health impact of outdoor air pollution is relatively well known but the report, from the Royal College of Physicians and the Royal College of Paediatrics and Child Health, also highlights the less understood impact of indoor pollution, as well as the growing evidence of harm to children's health and intelligence.
