More than 950 schools in the UK breathe illegal levels of air pollution.

The UK’s toxic air crisis is the biggest public health emergency facing the country and risks harming millions of children. We partnered with environmental lawyers ClientEarth to put pressure on the government. We launched an online film and targeted poster campaign in the 7 most polluted cities in the UK. Less than a week after the launch of our campaign, Sadiq Khan pledged to audit the country’s most polluted schools.
