I thought that London air quality was a bit ordinary.

Turns out it is really quite bad.

Interesting points:

“Poor air quality reduces the life expectancy of everyone in the UK by an average of seven to eight months and up to 50,000 people a year may die prematurely because of it. ”
“Estimated equivalent gain in life years (for air quality improvement) 39,058,000”
“Air Quality Strategy estimates that the health impact of man-made particulate air pollution experienced in the UK in 2005 cost between £8.5 billion and £20.2 billion a year.”
“European Court of Justice … reported that fines could reach £300 million “
