Beijing took 300,000 high-emission cars off its roads today, as part of measures to clean up the capital's air pollution and ease traffic on perennially clogged highways ahead of the Olympics.
Pollution is a major concern for many athletes ahead of the Games in August and the International Olympic Committee has said it may reschedule endurance events to remove a potential health risk.
The Chinese capital is one of the most polluted cities in the world and rapidly becoming one of the most congested, with about 1,000 extra cars crowding on to already choked roads every day.
The 300,000 "yellow grade" cars, which fall short of the city's benchmark emissions standards, would be banned from Beijing's roads until September 20th, Beijing's transport authority said.
Authorities had also banned trucks, tractors, and other "low-speed cargo vehicles" from entering Beijing municipal limits from neighbouring provinces, the Beijing Traffic Management Bureau said.
However, the measure appeared to have had little effect on traffic conditions in the city today, with major roads seeming as congested as ever.
Beijing claims to have already taken 50 per cent of government cars off the roads, and will ban private cars on alternate days from July 20th, depending on whether their number plates end in odd or even numbers.
The authorities hope such a measure will take 45 per cent of the city's 3.29 million cars off the roads and slash car emissions by 63 per cent.
The capital has also announced a raft of factory closures and a ban on major construction to take effect for two months from July 20th to improve air quality.
