At the end of October 2018, the Chinese government has issued the Atmospheric Pollution Prevention and Control Law (2018 Amendment), which will be implemented starting immediately. Experts believe that although the law is inevitably flawed in some aspects, if 80% of the law can be implemented, it is going to significantly improve the air quality. This law has been scrutinized three times. The new amendment has clearly stated out that enterprises of iron and steel, building materials, non-ferrous metals, petroleum, and chemical industry that discharge dust, sulfide, and nitrogen oxides in the course of production shall adopt cleaner production processes, construct dust-removing, desulfurization, and denitrification equipment in a complete set, or adopt technological transformation and other measures to control the discharge of air pollutants. Compared to the revised Air Pollution Control Law in 2000, the new version doubled the entries. Almost all the laws in the current version have been amended and revised to fit the current situation.
