“There is a ‘perfect storm’ of concerns about London’s air pollution in the run up to the Olympics” says Simon Birkett, Founder and Director, of Clean Air in London (CAL).
Annual mean levels of nitrogen dioxide (NO2), a toxic gas, are more than twice the legal limit and World Health Organisation (WHO) guideline near London busiest roads. NO2 levels in London were the highest of any capital city in Europe in 2010 and comparable with those in Beijing before it took action for the 2008 Olympics.
Air pollution matters. The Mayor has estimated 4,267 deaths were attributable to long-term exposure to ‘invisible’ airborne particles in London in 2008 which is similar to the 4,075 from short-term exposure to air pollution during the Great Smog of 1952 (when we knew nothing of long-term impacts). Only smoking causes more early deaths.
