More than 200,000 members of Beijing’s various driving clubs are being asked to leave their cars at home on at least one day each month in a bid to improve the air quality of the capital city.
Over 100 Beijing car clubs jointly launched the campaign on Monday calling on local drivers not to use their cars for at least one day every month. The goal of the exercise is to ease traffic congestion, reduce noise levels and improve the city’s air quality.
“I love driving but I’m willing to make my contribution for more blue sky days in Beijing and for myself,” said Lu Chuan, a film director and a former environmental ambassador who helped raise public awareness of China’s pollution issues.
