Responding to Mayor Boris Johnson's publication of his draft air quality strategy London Liberal Democrat MEP Sarah Ludford a long time campaigner for cleaner air in the capital said:
"We have a health emergency in the capital with thousands of avoidable deaths annually. Decisive measures are needed to slash the dangerous levels of nitrogen dioxide and airborne particles in central London and around Heathrow."
"But Mayor Johnson is still failing to take bold action. His suggestions include washing the streets planting trees and banning the running of engines when stationary. This is fiddling while Londoners die: he has no proposals to target pollution hotspots and has even delayed measures to tackle dirty vans."
