Sir Sadiq Khan said he is “thrilled” that London has achieved the “historic milestone”.

In 2019, experts at Kings College London estimated that without further action it would take 193 years for London to meet legal limits, but City Hall said Sir Sadiq has achieved this aim in nine years.

The figures, published by the Department for Environment, Food and Rural Affairs (Defra) this week, revealed that London met the air quality standards regulations for the first time in 2024, while Manchester, Birmingham and Liverpool exceeded those limits.
