Evaluation Report on Energy Saving and Emission Reduction of Chinese Enterprises during the Eleventh Five-Year Plan Period
Energy conservation and emission reduction is an important breakthrough for China to adjust its economic structure and realize the transformation of economic growth mode. To this end, the “Eleventh Five-Year Plan†proposes that by the end of 2010, the energy consumption per unit of GDP will be reduced by about 20%, the main pollutants. The total amount of emissions will be reduced by 10%. To promote energy conservation and emission reduction, enterprises are the main targets for achieving energy conservation and emission reduction, and protecting the environment and conserving resources are also important social responsibilities that enterprises should actively undertake. The "Eleventh Five-Year Plan" has ended. Comprehensively summarize the status of enterprises implementing energy conservation and emission reduction planning during the 11th Five-Year Plan period and the difficulties and obstacles encountered in energy conservation and emission reduction, and guide and promote further energy conservation and emission reduction during the “Twelfth Five-Year Plan†period, and complete the regulatory constraints. Sex indicators, realizing industrial transformation and upgrading and economic restructuring have realistic guiding significance, and have important reference value for the country to formulate the next step of energy conservation and emission reduction policies. I. Overall Situation and Achievements of Energy Saving and Emission Reduction of “Eleventh Five-Year Plan†During the “Eleventh Five-Year Plan†period, China’s economy grew at an average annual rate of more than 10%, while energy consumption grew at an average annual rate of less than 7%, and energy consumption growth was lower than that of the economy. Growth. According to the information provided by the National Development and Reform Commission and the Ministry of Environmental Protection, in the past five years, China has reduced energy consumption by 630 million tons of standard coal and reduced carbon dioxide emissions by 1.46 billion tons. The national unit GDP energy consumption decreased by about 19.10%, and the national chemical oxygen demand emissions and sulfur dioxide emissions decreased by 12.45% and 14.29%, respectively. Among them, the sulfur dioxide emission reduction target was achieved one year ahead of schedule, and the chemical oxygen demand reduction target was realized half a year ahead of schedule. . In general, the objectives set by the “Eleventh Five-Year Plan†are basically completed or exceeded. From the enterprise level, through the elimination of high energy-consuming backward production capacity, accelerating the application of energy-saving technologies, and tracking and controlling the total energy consumption, we will establish and deepen the energy management system, conduct hierarchical decomposition control of energy-saving emission reduction targets, and promote comprehensive utilization of resources. Strengthening the daily management of energy conservation and emission reduction work, and finally achieved good results, and made important contributions to ensuring the completion of the “Eleventh Five-Year Plan†energy conservation and emission reduction targets. 1. “Thousands of enterprises to save energy and reduce emissions†achieved outstanding results On April 13, 2006, the National Development and Reform Commission and other five ministries jointly issued a notice to decide on steel, nonferrous metals, coal, electricity, petroleum and petrochemical, chemical, building materials, textile, paper. Wait for 9 key energy-consuming industry organizations to carry out energy-saving actions for 1,000 enterprises. The activity refers to the state's energy conservation management of about 1,000 enterprises with an annual comprehensive energy consumption of 180,000 tons of standard coal, and its energy consumption accounts for half of industrial energy consumption. Since the launch of the “Thousands of Enterprises Energy Conservation and Emission Reduction Actionâ€, these enterprises have earnestly implemented the scientific development concept, and their emphasis on energy conservation has been significantly improved. The management system has been continuously improved and energy conservation investment has gradually increased. Through the comprehensive evaluation of the completion status of energy-saving targets and the implementation of energy-saving measures for 953 enterprises in Qianjia, 391 assessment results were over-achieved, accounting for 41%; 456 assessment results were completed, accounting for 47.8%; 32 assessment results For the basic completion level, accounting for 3.4%; 74 assessment results for the unfinished level, accounting for 7.8%. The “Thousands of Enterprises Energy Saving and Emission Reduction Action†has become an important starting point for promoting national energy conservation and emission reduction work, and has played a good demonstration role in the country. 2. The central enterprise is the leader and leader of energy conservation and emission reduction. The State-owned Assets Supervision and Administration Commission of the State Council attaches great importance to the energy conservation and emission reduction work of central enterprises. In the early 11th Five-Year Plan, the goal of energy conservation and emission reduction of central enterprises was determined, that is, to the 11th Five-Year Plan. At the end of the period, the central enterprises should ensure that the energy consumption per unit of added value is reduced by 20%, and the total discharge of major pollutants is reduced by 10%. Among them, petroleum, petrochemical, metallurgy, electric power, transportation, chemical, coal, building materials and other key industries must strive to 2009. At the end of the year, the above objectives are completed ahead of schedule. At the same time, the 30 key energy-consuming central enterprises identified by the State-owned Assets Supervision and Administration Commission, the energy consumption, water consumption and pollutant discharge indicators of all major production and operation businesses all reached the highest level in history, and more than one-third of the enterprises approached or reached the international level. Advanced level. Other central enterprises should implement energy conservation and emission reduction responsibility systems focusing on energy conservation, material saving, water conservation, land saving and pollutant emission reduction, and contribute to the realization of national energy conservation and emission reduction targets. 3. Significant achievements in energy conservation and emission reduction in key industries Statistics show that at present, China's energy consumption ratio, industry accounts for about 70% of the total, industrial production is the main source of environmental pollution. Therefore, the energy-saving effect of industry directly affects the realization of the “Eleventh Five-Year†energy-saving goal. During the “Eleventh Five-Year Plan†period, many traditional key energy-consuming industries have achieved remarkable results in energy conservation and emission reduction. Many industries have completed and exceeded the “Eleventh Five-Year Plan†constraints of the industry ahead of schedule. For example, the power industry completed the “Eleventh Five-Year Plan†energy conservation and emission reduction planning targets ahead of the end of 2009, and made important contributions to the realization of national energy conservation and emission reduction targets. Compared with 2005, the coal consumption of thermal power supply decreased from 370 g/kWh to 340 g/kWh, a decrease of 8.11%. In the first four years of the “Eleventh Five-Year Planâ€, the coal industry consumed 490 million tons of standard coal and reduced carbon dioxide emissions by 1.13 billion tons. Compared with 2005, the comprehensive energy consumption per ton of steel in the steel industry decreased from 694 kg of standard coal to 615 kg of standard coal, a decrease of 11.4%. II. Typical Experiences of Energy Saving and Emission Reduction of Enterprises During the “Eleventh Five-Year Plan†period, Chinese enterprises have boldly innovated. While completing the task of energy conservation and emission reduction, they have formed many advanced experiences and successful models, which are worthy of reference and promotion. 1. Accelerating the adjustment of product structure and accelerating the adjustment of product structure is the fundamental way to save energy and reduce emissions. During the “Eleventh Five-Year Plan†period, Chinese enterprises have begun to adjust product structure from various aspects: First, control the rapid growth of products with high energy consumption and high pollution; The second is to eliminate backward production capacity, process equipment and technical equipment in high-energy-consumption and high-pollution industries according to law, and then update products and productivity; third, accelerate the development of service industries and high-tech industries. 2. Relying on scientific and technological progress Science and technology are the primary productive forces. The potential for promoting energy conservation and emission reduction through technological advancement is very large. Many enterprises have achieved “three accelerations†to promote the promotion of energy conservation and emission reduction by technological advancement. First, accelerate the research and development of energy conservation and emission reduction technologies; Industrialization demonstration and promotion; third, accelerate the establishment of energy-saving technology service system. 3. Efforts to develop new energy New energy has the characteristics of low energy consumption and low emissions, and is called clean and efficient energy. By striving to develop new energy alternatives to traditional energy sources, some companies have reduced energy consumption and emissions in new ways, and have provided society with low-energy and low-emission products and services, reducing energy consumption and emissions to a greater extent. 4. Strengthening and improving the management system Efforts to strengthen management and improve the management system are important measures for energy conservation and emission reduction. Relevant information shows that the contribution rate of energy conservation to all energy conservation can reach 15%, which is the least expensive and the most effective way to save energy. At present, the potential of energy management is huge, both in the production and consumption sectors. Therefore, strengthen management, improve the system, implement responsibilities, and strictly supervise, and establish an energy-saving emission reduction management system and operational mechanism with “clear objectives, responsible implementation, clear rewards and punishments, first-level first-level, first-level assessmentâ€. It seems very necessary and urgent. 5. Adjusting the energy use structure While operating the original products and services, the company will vigorously develop renewable energy and steadily develop alternative energy sources through the structural adjustment and replacement of energy raw materials, which is also the main way to achieve energy conservation and emission reduction. Domestic companies have had many excellent cases in this regard. 6. Improve production layout The production and operation of large enterprises often span different regions and industries, which also provides ample space for enterprises to promote energy conservation and emission reduction. Some enterprises have actively improved their business layout according to the resource endowments and industrial advantages of different regions, and achieved remarkable results in energy conservation and emission reduction. 7. Promote green supply chain The status of the supply chain directly determines the cost and quality of the product, as well as energy conservation and emission reduction. The practice of some enterprises shows that the implementation of green supply chain is an effective way to save energy and reduce emissions. III. Motivation Factors and Evaluation of Energy Saving and Emission Reduction of Chinese Enterprises Since the “Eleventh Five-Year Planâ€, Chinese enterprises have made important progress in energy conservation and emission reduction. It should be said that the world of energy conservation and emission reduction is rare, and its effectiveness ranks among the top in the world. Under the current development stage and institutional environment, several factors have effectively promoted and promoted energy conservation and emission reduction. 1. Administrative power is the primary driving force for energy conservation and emission reduction of enterprises. Although Chinese enterprises have seized the opportunity of rapid macroeconomic growth in recent years and achieved leap-forward development, compared with developed countries, Chinese enterprises still have economies of scale and technology. Relatively backward. Therefore, many enterprises still regard the continued growth as the primary goal, coupled with the external nature of high energy consumption and high emissions, making the internal dynamics of energy conservation and emission reduction of Chinese enterprises at this stage insufficient. However, the current extensive development model is indeed difficult. Following. From the perspective of sustainable economic and social development, under the current institutional environment, the government has naturally become the primary driving force for energy conservation and emission reduction. In order to ensure the completion of the “Eleventh Five-Year Plan†energy conservation and emission reduction targets, the State Council issued a series of documents to supervise the implementation. In 2006, the State Council issued the "Decision on Strengthening Energy Conservation Work." Since then, the provinces have also issued corresponding documents. Under the administrative accountability system, the completion of energy conservation and emission reduction targets is an important criterion for testing the effectiveness of local economic development. The results of the annual assessment are handed over to the competent department of the cadre as an important basis for the comprehensive evaluation and evaluation of the leadership and leading cadres of the provincial people's government, and announced to the public to play the supervisory role of the society and public opinion. 2. Huge investment is the direct driving force for energy conservation and emission reduction. Energy conservation and emission reduction require a lot of investment. In this regard, during the “Eleventh Five-Year Plan†period, the government has exerted the guiding function of “tangible hand†through huge financial investment, with clear policy guidance, reduced the burden of capital investment of enterprises, and engaged in energy conservation for enterprises. The development of platoon technology has created the necessary market space. According to statistics, during the “Eleventh Five-Year Plan†period, the central government invested more than 200 billion yuan in energy conservation and emission reduction, which drove the energy conservation and environmental protection investment of governments and enterprises at all levels in the country. With the most conservative figures, it is more than 1.6 trillion yuan. During the 10th Five-Year Plan period, it increased by 70%. The National Science and Technology Plan has arranged a total of more than 10 billion yuan for energy conservation and emission reduction research and development projects, which provides a strong support for the reduction of GDP energy consumption and emissions of major pollutants. The government has invested in the implementation of waste heat recovery and utilization of industrial boilers, saving and replacing ten key energy-saving projects such as petroleum, building energy conservation and green lighting, forming energy-saving capacity of 260 million tons of standard coal, and vigorously building urban sewage and garbage treatment facilities. The daily sewage treatment capacity of Zengcheng Town was 45.6 million tons. The flue gas desulfurization device of thermal power plant was generally built. The desulfurization device put into operation reached 460 million kilowatts, and more than 360 million energy-saving lamps and 200,000 energy-saving vehicles were promoted by means of financial subsidies. Energy-saving products such as motors. 3. Laws and regulations are an important system guarantee for energy conservation and emission reduction In the current economic and institutional environment, on the one hand, the Chinese government uses administrative means to promote energy conservation and emission reduction work, and at the same time adapt to the requirements of the market economy, and constantly raise administrative orders into laws and regulations. Promote the realization of energy conservation and emission reduction targets with the help of economic laws. The National People's Republic of China officially promulgated the newly revised Energy Conservation Law on October 28, 2007. The Circular Economy Promotion Law was implemented on January 1, 2009. The Chinese government has made three efforts in strengthening the legal system to promote energy conservation and emission reduction. First, we will improve laws and regulations, improve the energy conservation measures and useful experiences formed in practice and reform as law, improve and promulgate the implementation of "energy conservation." Laws, "Circular Economy Law", "Water Pollution Prevention Law", "Air Pollution Prevention and Control Law" and other energy conservation and emission reduction laws and regulations, increase penalties, and effectively solve the problem of "low illegal costs and high law-abiding costs." The second is to improve standards, formulate and improve energy efficiency standards for major industrial energy-consuming equipment, household appliances, lighting appliances, and motor vehicles, organize revision and improvement of energy-saving design codes and building energy-saving standards for major energy-consuming industries, and accelerate the development of building cooling and heating temperatures. Control standards, etc., provide a basis for law enforcement supervision of energy conservation and emission reduction, and establishment of energy conservation and environmental protection technology. The third is to strictly enforce the law, seriously investigate and deal with all kinds of ecological and environmental violations, and form a good atmosphere of energy conservation and emission reduction according to law. 4. Green barriers in the international market are important binding forces for energy conservation and emission reduction Since the environmental standards in the international market are generally higher than domestic, the green barriers in the international market have become an important binding force for enterprises, especially export enterprises, to implement energy conservation and emission reduction. For example, in February 2003 the European Union enacted the Waste Electrical and Electronic Equipment Directive and the Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. Under the influence of Europe and the United States, countries have introduced product energy efficiency and emission-restricted standards. The role of resources and environmental factors in international trade has become increasingly prominent. Global green barriers have placed high demands on energy efficiency and emission targets. The introduction of a series of regulations and technical standards for environmental protection and energy conservation in developed countries has objectively formed a "green barrier" in international trade. At the same time, due to China's past low standards for energy conservation and emission reduction, such as environmental quality and pollution control, China's enterprises are not motivated to improve product quality and improve environmental standards, and high-energy, high-pollution and other environmentally sensitive industries. Finished goods account for a considerable proportion of export trade. Therefore, only by adopting technical standards that meet the requirements of resources and environmental protection in international trade can Chinese enterprises obtain a “green pass†to enter the international market. Energy saving and emission reduction is not only the only way for enterprises to enhance their international competitiveness, but also the ticket for accelerating integration into the international market in the era of globalization. In summary, during the “Eleventh Five-Year Plan†period, China adhered to the promotion of energy conservation and development, coordinated development and conservation, combined government regulation and market mechanisms, and comprehensively applied economic, legal, technical and necessary administrative means to effectively carry out The company's energy conservation and emission reduction work will ultimately ensure the completion of the “Eleventh Five-Year Plan†energy conservation and emission reduction targets. It should be said that the completion of the "Eleventh Five-Year Plan" energy conservation and emission reduction targets is the result of a combination of various factors. Investigating the various driving factors that promote energy conservation and emission reduction, it can be seen that the administrative mechanism is the biggest driving force, and the promulgation and implementation of relevant laws and regulations ensure the sustainability of the role of administrative forces. Huge capital investment is the direct driving force for energy conservation and emission reduction. The market mechanism plays an increasingly important role in energy conservation and emission reduction. The endogenous power of enterprises to carry out energy conservation and emission reduction has gradually increased, and more and more enterprises are considering energy conservation and emission reduction in the long run.
