随着城市汽车拥有量的急剧增加,现在国内城市大气污染的主要原因已转变为汽车尾气排放。据环保部数据测算,“十二五”期间我国还将新增机动车一亿辆左右,新增汽柴油消耗量1亿至1.5亿吨。随着车辆的增加,汽车与城市环境之间的矛盾越来越尖锐。有关环保专家认为,机动车尾气是城市空气的最大污染源,汽车尾气的排放污染是当前和今后一段时期控制空气质量最突出、最紧迫的问题。
With the dramatic increase in urban car ownership, the main cause of air pollution in domestic cities has now been transformed into vehicle exhaust. According to the data from the Ministry of Environmental Protection, there will be an additional 100 million motor vehicles in China during the “Twelfth Five-Year Plan” period, and the additional consumption of gasoline and diesel will be between 100 million and 150 million tons. As the number of vehicles increases, conflicts between cars and the urban environment become more and more acute. Relevant environmental experts believe that motor vehicle exhaust is the largest source of urban air pollution. The emission of automobile exhaust gas is the most prominent and urgent problem in the control of air quality at present and for some time to come.
