2013年初以来,我国许多地区雾霾天气盛行,加速了国家及各地政府部门对改善大气质量措施的出台,其中即包括机动车排放标准的升级。虽然,机动车排放污染物只是形成“雾霾”一支重要力量,而不是主要力量;但作为业者,担起守望那份“净土”的责任可谓义不容辞。 Since the beginning of 2013, hazy weather has prevailed in many areas of our country, accelerating the introduction of measures to improve air quality at the national and local government departments, including the upgrading of vehicle emission standards. Although the emission of pollutants by motor vehicles is only an important force rather than a major force in “haze,” it is incumbent on the industry to shoulder the responsibility of keeping a watch on the “Pure Lands.”
