NEW YORK (KGO) -- An alarming report says hundreds of millions of children are living with toxic levels of air pollution.
Unicef's report says 300 million children world-wide are living with outdoor pollution that exceeds global guidelines set by the world health organization. The study refers to areas six or more times higher in pollution than international guidelines would suggest.
Unicef will call on world leaders to take action against air pollution at a climate change conference next week.
