The formulated emission standards can promote technological innovation in production processes and industrial restructuring, and optimize economic development.

5.3 The  principle of fairness. The standards preparation unit should be environmental protection and public welfare, be able to objectively and impartially investigate and evaluate the production process of the pollution source, the atmospheric pollutant discharge situation, and the level of emission control technology, etc., and truly reflect the emission characteristics of the emission source, and refer to the control of similar foreign emission standards. Standards are formulated based on technical level and opinions from environmental protection, industrial production, and the public to ensure standards are fair and credible.

5.4  Reachability Principle. The production process and emission control technology should be classified and classified, and the compliance technologies and economic costs of various types of emission limits, as well as the compliance technologies or technology combinations of each type of enterprise after the implementation of the standards, make the formulated emission standards technically feasible and economical. Reasonable and operable.

5.5  Coordination principles. The emission standards formulated should be linked to other industry-type, general-purpose or comprehensive air pollutant emission standards to avoid cross-overlaps and be accompanied by applicable environmental monitoring standards.
