Almost one in seven of the world’s children, 300 million, live in areas with the most toxic levels of outdoor air pollution – six or more times higher than international guidelines – reveals a new UNICEF report. Clear the Air for Children uses satellite imagery to show for the first time how many children are exposed to outdoor pollution that exceeds global guidelines set by the World Health Organization (WHO), and where they live across the globe.

[2]The findings come a week ahead of the COP 22 in Marrakesh, Morocco, where UNICEF is calling on world leaders to take urgent action to cut air pollution in their countries. Air pollution is a major contributing factor in the deaths of around 600,000 children under five every year – and it threatens the lives and futures of millions more every day. Pollutants don’t only harm children’s developing lungs – they can actually cross the blood-brain barrier and permanently damage their developing brains – and, thus, their futures. No society can afford to ignore air pollution.
