随着能源短缺、全球暖化等问题的日益严峻,社会各界普遍认识到以燃油汽车为主导的传统交通方式将不具有可持续性。以我国为例,2010年交通领域所消耗的原油约占原油总消耗量的68%,其中汽车消耗量占57%左右。据预测,到2020年,我国全年汽车年成品油消耗将达到3亿吨,按照60%的成品油率来换算,年消耗原油约5亿吨,由此而造成的二氧化碳排放量应该在12.5亿吨到15亿吨之间。
With the energy shortage and the global warming worsening, the society has generally realized that the traditional means of transportation dominated by fuel cars will not be sustainable. In our country, for example, the crude oil consumed in the transport sector accounted for about 68% of the total crude oil consumption in 2010, of which car consumption accounted for about 57%. It is predicted that by 2020, China’s annual car oil consumption will reach 300 million tons, according to 60% of the refined oil conversion, annual consumption of about 500 million tons of crude oil, resulting in carbon dioxide emissions should be 12.5 Between 100 million tons and 1.5 billion tons.
