Boris focuses on diesel cars, and new measures of AQ for cities

Really interesting piece by Air Quality News writing up Boris Johnson’s evidence at the Environmental Audit Committee – “the government needs a diesel car scrappage scheme” plus he says the EU “needs to match his own ambitious plans” although there was no detail on that:

Plus he commissioned research to produce new AQ measures,, which independent review says “resulting ranking clearly shows that London is not the best or worst of the cities compared, but lies somewhere in the middle of the European cities.”
