Environmental law firm ClientEarth have dragged the government back to court over its “moral and legal failure” to tackle air pollution in the UK. Defra announced it would introduce clean air zones in major cities in the UK, but Manchester, Liverpool and Glasgow have fallen short of requirement to have them.

Air pollution causes 50,000 early deaths and £27.5bn in costs every year. Failure to address the issue nationally is nothing short of ridiculous.
