It’s the third annual International Day of Clean Air for Blue Skies on Wednesday 7 September. It’s aimed at raising public awareness at all levels of the urgent need to improve air quality. Air pollution is the largest contributor to the burden of disease from the environment, and is one of the main avoidable causes of death and disease globally – killing seven million people a year according to the World Health Organisation. Kim Chakanetsa talks to women from the UK and India who are calling on governments and industry to reduce air pollution.

Rosamund Adoo-Kissi-Debrah's daughter Ella died, aged nine, after a violent asthma attack in 2013. Since then Rosamund has become one of the most prominent advocates for clean air worldwide. She challenged a coroner's inquest into her daughter's death and succeeded in getting the death certificate changed to show Ella had died as a result of air pollution. Rosamund is now a WHO BreatheLife ambassador and the founder, director, and trustee of the Ella Roberta Foundation.

Bhavreen Kandhari lives in New Delhi - the most polluted capital city in the world. She has 18 year old twin daughters and is part of Warrior Moms – a group of women from across India connecting with other clean air campaigns globally to bring attention to the issue of air pollution.
