On November 17, our reporter exclusively learned that the Ministry of Environmental Protection's "Twelfth Five-Year Plan" has initially formulated the total control targets for sulfur dioxide and chemical oxygen demand (COD). By 2015, the total emissions of sulfur dioxide will be reduced by 10% compared with 2010, while the total emissions of COD will be reduced by 5% compared with 2010. The total amount control of sulfur dioxide has continued the "11th Five-Year" target, while the COD emission reduction target has been reduced by half (the "11th Five-Year" target is a 10% reduction). "It's a surprising change that the COD target has dropped so much," a researcher at the Environmental and Economic Policy Research Center of the Ministry of Environmental Protection told reporters. During the "Eleventh Five-Year Plan" period, COD emission reduction is very difficult compared to sulfur dioxide. Zhao Hualin, director of the total pollutant discharge control department of the Ministry of Environmental Protection, publicly stated at the 2010 annual meeting of the China Council for International Cooperation on Environment and Development held recently that the emission reduction methods during the "Twelfth Five-Year Plan" period should start from the "Eleventh Five-Year Plan" period. The project emission reduction is mainly converted to structural emission reduction. "Structural emission reduction is more difficult. Adjusting the structure involves a wide range of aspects, and it is easy to hurt the bones." An official of the local environmental protection system told reporters that it is not difficult to achieve the emission reduction target. "In many places In addition to the emission reduction targets and emission reduction methods, the base of emission reduction also attracts attention. According to people familiar with the matter, within the Ministry of Environmental Protection, there has been controversy over whether to use the 2010 data as the base or the 2005 data as the base. From project emission reduction to structural emission reduction The reporter learned that the emission reduction during the "Eleventh Five-Year Plan" period is mainly completed by engineering emission reduction, and this method has been unsustainable. During the "Eleventh Five-Year Plan" period, sulfur dioxide and COD were included in the assessment scope of total amount control as binding indicators for the first time. "At the beginning of the project, the emission reduction of the project is necessary, and this is often the main method, because this method is relatively simple to operate." The aforementioned local environmental protection official told reporters. "Today's installed capacity of desulfurization units is ten times that of before 2005, from 40 million kilowatts to 470 million kilowatts." Zhao Hualin said that the daily processing capacity of urban sewage treatment plants has increased from 50 million tons in 2005 to 100 million last year. Tons of sewage treatment capacity, the number of sewage treatment plants constructed during the "Eleventh Five-Year Plan" period is double the total in the previous 50 years. However, the aforementioned local officials told reporters that the total amount and speed of such emission reduction projects are approaching the limit, so new breakthroughs in emission reduction must be found during the "Twelfth Five-Year Plan" period. "Under the current international situation of climate negotiations, it is difficult to fulfill the carbon-intensive emission reduction targets and commitments without adjusting the structure." The aforementioned researcher from the Environmental and Economic Policy Research Center of the Ministry of Environmental Protection believes that this time it is time to make a real move. The so-called structural emission reduction is to achieve total emission reduction by adjusting the economic structure, industrial structure and production structure, and this requires the active cooperation of various ministries and commissions. The reporter learned that the National Energy Administration is committed to promoting the formulation and decomposition of regional coal-fired total targets. However, it is difficult for the local government to form practical and effective constraints on the central enterprises that are really big emitters. "It is suggested that in key industries with high emissions, such as the power industry, the total amount of coal burning should be controlled, so as to fundamentally control the increase in sulfur dioxide emissions." A researcher from the Central Compilation and Translation Bureau told reporters. Disputed emission reduction base years Compared with whether the emission reduction target can be achieved, Zhang Jianyu, head of the US Environmental Protection Association's China project, is more concerned about the emission reduction base. He believes that if the emission data in 2010 is used as the base, it is not conducive to the participation of various regions and enterprises in reducing emissions. "Assume that province A has overfulfilled the emission reduction task during the '11th Five-Year' period, while province B has only completed the specified emission reduction task. If the data in 2010 is used as the base, then province A is obviously a further reduction than province B. It is more difficult to rank.” Zhang Jianyu said that if the same ratio is required to be reduced on the basis of 2010 emissions, it is obvious that the provinces that “run fast” during the “Eleventh Five-Year Plan” period will suffer a lot, and this design is very unfair to it. , dampened its enthusiasm. It is fairer to use 2005 data as the base. However, a bigger challenge is that since one of the country's three major principles of pollutant control during the "Eleventh Five-Year Plan" period is to dilute the base, it is doubtful whether the base in 2005 is accurate and scientific. If we continue to use this data as the base for the total control of the "Twelfth Five-Year Plan", will it be "wrong plus wrong"? "This is a big contradiction, and the country needs to make a choice after weighing it." The aforementioned researcher from the Environmental and Economic Policy Research Center of the Ministry of Environmental Protection told reporters that the solution to this problem involves the "13th Five-Year Plan" and more long-term The strategic arrangement of emission reduction must be properly resolved. Zhang Jianyu said that after determining the base, how to improve the decomposition method from the central to the local and from the local to the enterprise during the "Eleventh Five-Year Plan" period will be a top priority.
