As the clock ticks towards one year out from the Beijing Olympic Games, a thick blanket of haze wedged over the capital for several weeks is casting a polluted shadow over countdown celebrations. International Olympic Committee officials have repeatedly warned that bad air quality is one of the biggest threats to the success of the 2008 Games, and authorities are working overtime to ensure blue skies during the event.
The government will next week take one million cars off the city's roads for a fortnight to test-run one of its most important tactics in engineering a sudden, temporary lifting of the pollution for Olympic athletes and visitors. Building work will also be restricted next year, artificial rain may be induced to clear the air, and many of Beijing's biggest polluting factories will by then have been moved out of the capital.
But the pollution haze that has been hanging over Beijing for weeks ahead of next week's August 8 one-year countdown illustrates the enormity of tackling the problem.
EDIT
Surrounding provinces and cities, which all follow the same economic model that has made China one of the most polluted countries in the world, could blow a dark cloud over Beijing's Olympic party. "Several lines of evidence are now converging on the idea that roughly half of Beijing's air pollution comes from outside it. At the height of typical (pollution) episodes, that figure is higher," he said.
