The new UNICEF report (October 2016) addresses the last and very concerning numbers about children and the air quality in the world. Overall,
- Around 2 billion children live in areas where outdoor air quality exceeds international limits
- 300 million children live in areas with pollution above 6 times international limits
- In Europe, between 20 and 120 million are living in areas where outdoor air quality exceeds up to 2 times international limits
This is a very good document, well written and easy to read. More information here: https://www.unicef.org/publications/index_92957.html
