Application of AHP Fuzzy Preference Programming to Evaluate Environmental Externality of Emission Sources

Based on environmental economics literature review and in-depth analyses, this paper identified five rules to evaluate environmental externality of emission sources, which are current environmental condition, amount of people injured, economic development level, physical geography characters, and natural scenery and cultural heritage. Under the framework of analytic hierarchy process (AHP), this paper presented a method to evaluate the priorities of several emission sources by combing with fuzzy preference programming. Numerical example shows that emission source´s environmental externality can be valued by the AHP fuzzy preference programming, and the application of this method is beneficial to administrative management and the construction of emission trading system.
