Investigation On Methodology For SO2 Emission Trading In Petrochemical Corporation In Liaoning Province

With the rapid development of economy in China, the environmental pollution becomes increasingly serious. The implementation of traditional command and control environmental protection policies and economic means that represented by Sewage charges has not obtained satisfactory results. The economic development and environmental protection contradictions have become increasingly prominent. Emissions trading as a new pollution control policy can reduce the cost of pollution control under the same total amount of pollution, and thereby the conflict between the economic development and environmental protection became weakened. In this paper, basing on the SO2 pollution conditions in Liaoning Province, combing with the theory of emission right, the major pollutants SO2 emissions trading in this area was designed.(1) According to Coase theorem, the basic theory of emissions trading was expounded; basing on the Pareto criteria, the economic efficiency of enterprises was analyzed;(2) The SO2 trading framework and logic relation -ships were constructed, and the PDCA model was applied to the operation of the emissions trading system;(3) Based on the principles for allowance allocation, including that the allocated allowances do not exceed the total control level, allocation of allowances should be fair to all participating enterprises and favorable to those industries that have less pollution and good productivity. The allowances allocation methods such as historical emissions method, heat quantity of coal combustion method and production value method were systematic analyzed, calculated and compared in allocating the SO2 emissions trading among Jinzhou Pertrochemical Corporation, Jinxi Pertrochemical Corporation, Dalian Pertrochemical Corporation, Fushun Pertrochemical Corporation, Liaoyang Pertrochemical Corporation and Liaohe Pertrochemical Corporation. The results indicated production value method was the most suitable one for Pertrochemical Corporation in Liaoning Province and the allocation scheme was put forward with this method;(4) Basing on the theory of emissions trading system, the emissions trading of SO2 in six Pertrochemical Corporations in Liaoning was designed. The results indicated that the proper price of SO2 emissions was 840 to 950 yuan per ton. The trading could work well and make the social total cost of decreasing specified emission quantities at this price.In this paper, using the integrated methods of environment, management, economics, and so on, the SO2 emission trading system was investigated, and thereby we provide a certain amount of technical support for SO2 emissions trading in Liaoning Province.
