The recently published peer-reviewed report comparing air quality in different cities showed that London ranked 15th out of 36 cities and 9th best when you focus on pollutants with the worst health effects.

As the report notes different cities adopt different approaches to the siting of their monitoring stations, which means that it is not possible to compare the worst location in one city with another. The overall rankings, therefore, remain the best way of assessing comparative city performance.
