Chinese authorities are believed to be planning further measures to curb pollution in Beijing before the start of the Olympic Games.
Beijing has brought in a whole range of measures to reduce the city’s notorious air pollution, ahead of the Olympics.
They include removing more than one million cars from the roads of the capital, shutting down polluting factories, and closing dusty construction sites.
But so far those policies don’t appear to be working – for the fourth day in a row there is a thick layer of grey smog hanging over Beijing.
Now some officials are suggesting they may take more drastic action to improve air quality, including banning 90 per cent of all private cars from the streets of Beijing.
