China’s current air quality standards include two classes of limit values. Class 1 standards apply to special regions such as national parks. Class 2 standards apply to all other areas, including urban and industrial areas. Earlier versions of the standard included a third class – special industrial areas – but this class was eliminated in the 2012 standard.
