Half of the two million annual child deaths from acute respiratory infections are attributable to indoor air pollution.

Acute respiratory infections – in particular pneumonia – are the biggest killer of young children. Nearly half of these deaths are attributable to indoor smoke from solid fuel. Second-hand tobacco smoke is another major risk factor. Children in developing countries are especially at risk due to poor housing conditions.
