If the rest of the EU is interested in the effect that EMISSIONS were having on it then it should have some standards in place for EMISSIONS, whether these take place in London or anywhere else.
Focusing on the LEVEL of air pollution in major urban centers is no real proxy at all for EMISSIONS from the country as a whole.
