Hidden in Plain Sight: Why the UK needs a new Clean Air Act
Air pollution is often invisible. But its impact is everywhere.
That’s why the Healthy Air Coalition is launching the Hidden in Plain Sight campaign, calling on the Government to deliver a new, modern Clean Air Act that protects everyone’s right to breathe clean air.
Today, 98.7% of people in England live in areas exceeding World Health Organization guidelines for fine particulate matter PM2.5 pollution. That’s 57.9 million people breathing unsafe air.
And while many think of air pollution as a city problem, toxic air affects rural communities too. Areas including Cannock Chase, West Suffolk and Cornwall are estimated to have pollution levels comparable to Birmingham and Luton.

The burden is not shared equally. Across England, 27 areas face a “double burden” of the highest pollution levels combined with the highest levels of deprivation.
We are calling on the Government to honour its commitment to public health by introducing a new Clean Air Act that adopts World Health Organization guidelines and prevents air quality targets from being weakened in the future.
