China, the entire country, will have a car free day on September 22, 2008. China plans to ban cars from streets in 108 cities in its first ``No Car Day'' on Sept. 22, part of an effort to promote environmental protection and ease congestion in the world's second-largest auto market. Streets in areas of Beijing, Shanghai and other cities will be open only to pedestrians, bicycles, taxis and buses from 7 a.m. to 7 p.m., according to the Ministry of Construction. Sept. 22 is World Carfree Day, a United Nations-backed global campaign. About 4.37 million new vehicles began using China's roads in the first half as economic growth makes cars and trucks affordable to more people. Growth in traffic helped China surpass the U.S. as the world's largest carbon-dioxide emitter last year. ‘No Car Day' will cut 3,000 tons of emissions and save 33 million liters of gasoline.
