    Soochow Huaene, recovering the data of pollution load, tracing the source of haze management

    In order to manage haze, the central government allocated 10.6 billion yuan of special funds for air pollution prevention and control in 2015, and carried out air pollution management in key areas. Meanwhile, emission reduction measures and environmental protection monitoring were constantly introduced and strengthened. But haze still exists today. Industry insiders have shown that the root of the pollution data distortion, even vigorous management, can not alleviate the haze.

    Haze management:

    Tracing the root cause of the need for haze management to recover pollution load data

    Last month, the fog and haze lasted for nearly 14 days, which made the air quality of 49 cities in Beijing, Tianjin, Hebei and its surrounding areas seriously polluted. Among them, 16 cities were seriously polluted by air. Environmental protection departments around the country intensified law enforcement and inspection. More than 20,000 environmental law enforcement officers were dispatched from Beijing, Tianjin, Hebei and the surrounding areas to implement various emergency emission reduction measures.

    The shadows have not been completely dispersed yet. As the New Year approaches, the haze will rise again. It seems that the vigorous emission reduction and heavy environmental monitoring in the early stage have not come into effect in time.

    "The formulation of each emission reduction mission is based on the 2010"First National Pollution Source Census Bulletin". However, due to the fact that the underlying data of the bulletin has errors with reality, even if vigorously managed, it still feels that the haze has not been alleviated. A low-level EPA staff member said.

    Loop system data distortion:

    In order to manage haze, the central government allocated 10.6 billion yuan of special funds for air pollution prevention and control in 2016 to support waste gas management in key areas such as Beijing, Tianjin and Hebei, the Yangtze River Delta and the Pearl River Delta. The whole country fully supplies four standard automotive gasoline and diesel, and Beijing, Tianjin, Shanghai and other places take the lead in supplying five standard automotive gasoline and diesel. Over the past three years, more than 9 million tons of backward ironmaking and steelmaking capacity, more than 1 million tons of electrolytic aluminium, 230 million tons of cement and more than 76 million components of flat glass have been selected. Promote clean and efficient utilization of coal, Beijing, Tianjin and Hebei and other key areas to achieve negative growth in coal consumption.

    These figures, in front of the haze, seem a little helpless.

    China's environmental accounting data began in 2007. In February 2010, the national environmental pollutant accounting data came out, namely the First National Pollution Source Census Bulletin issued jointly by the Ministry of Environmental Protection, the State Accounting Bureau and the Ministry of Agriculture. The Bulletin shows that the total amount of waste gas emissions in China is 637.239 billion cubic meters, of which 23.2 million tons are sulphur dioxide, 116.664 million tons are smoke and dust, and 17.977 million tons are nitrogen oxides.

    Over the past few years, emission reduction measures and environmental monitoring have been introduced and strengthened. A few days ago, the State Council issued the "13th Five-Year" Energy Conservation and Emission Reduction Summary Work Programme, which requires that by 2020, the national GDP energy consumption of 10,000 yuan will be 15% lower than that of 2015, and the total energy consumption should be controlled within 5 billion tons of standard coal. The total emissions of chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides in China are 10%, 10%, 15% and 15% lower than in 2015, respectively. Volatile Organic Compounds (VOCs) emissions in China are more than 10% lower than in 2015, and the share of total VOCs emissions is included in the planning policy for the first time.

    So why does the haze still exist? According to the above-mentioned environmentalists, "Reducing emissions in 2015 will be based on 2010 data, and then in 2020 on 2015, but it will be banned in 2010 and digital games in the future. Although the emission of pollutants is decreasing year by year, the haze is aggravating on the contrary.

    "Generally speaking, the environmental protection system has more than three sets of system data, separated from monitoring data, sewage charges data and environmental accounting data. These three sets of data are related to pollution load and pollutant discharge. Before the first national pollution source census, there was an order of magnitude difference between the three sets of data. To this end, the national resolution to conduct a national first pollution source census, the original intention is to clarify China's pollutant emission base, but for various reasons, the data are still distorted. The environmental protection personnel mentioned above indicated that.

    According to its introduction, the environmental accounting data published in 2010 is to use environmental accounting software to select 80% of the enterprises with regional environmental pollution load as the key enterprises and other non-key sources. However, the base of annual environmental accounting will be distorted due to the problems of enterprise omission or data distortion.

    "Some enterprises have no approval procedures or'guerrilla'and other non-standard problems. Local environmental protection departments have not included them in the accounting data due to subsequent troubles, which presents the situation of underreporting. Generally, the annual environmental accounting data are set in accordance with the past practice, and then allocated, while the newly-built enterprises, when they complete the input when they have the total target, will present the situation that the input is not timely. For example, a city in 2010 data set, and then according to this data distributed to the following districts and counties, remove emission reduction data, calculate the data for 2010 and future years. The environmental protection personnel mentioned above indicated that.

    In the future, the annual emission reduction will be calculated on the basis of this data, and those enterprises outside the data will not be included in the calculation. This is why the haze is still brutal no matter how much emissions are reduced and how much supervision is strengthened.

    "There are many reasons that lead to the prohibition of the basic data. First, the accounting is not comprehensive, such as the amount of coal gangue spontaneous combustion pollution, petroleum coke, funeral industry and so on, as well as the lack of accounting, including some intermittent production, guerrilla small enterprises, etc. Second, some state-controlled sources, city-controlled sources and other key list of enterprises data distortion." The environmental protection personnel mentioned above indicated that.

    "The most lethal thing is that the current loop system has a problem, that is, the loop system has selected the pollution load to account for 8 percent.
