• Drivers ‘likely to benefit from London Ulez’

Rosamund Adoo-Kissi-Debrah reserves a withering eye roll for people who question the impact that air pollution has on the health of children living in London. It helps her to shrug off the increasingly politicised debate over what needs to be done to improve the capital’s air quality.

Adoo-Kissi-Debrah fought a calm and determined campaign for seven years to make sure air pollution was included on her daughter Ella’s death certificate, and in December 2020 a second inquest ruled that air pollution contributed to Ella’s death from asthma in 2013.
