Beijing has just issued its first ever ‘Red Alert’ of dangerous smog levels, which will see much of China’s capital city shutdown and half of its cars forced off the roads. As part of the Red Alert, cars in Beijing can only be driven on alternating days with those with odd numbered license plates allowed to drive one day and even numbered license plates permitted to drive the following day. Beyond the effective halving of cars from Beijing residents allowed on the roads between yesterday and Thursday, the New York Times says 30 per cent of the vehicle fleets from government agencies will be taken off the roads.The silver lining in this cloud of smog is that China recognises these problems and this year, it is set to become the world’s largest market for electric cars.
