Environmental Performance Assessment Reaserch On X Minning Group Based On Eco-efficiency Index

After industrial revolution, the global economy is developing rapidly, but modern industry also results in a lot of unspeakable "pain" for the human, such as extreme weather, haze, city garbage, algae bloom in Taihu Lake, global warming, and so on. Those environmental pollution problems not only have become a bottleneck in the development of modern industry, also a big restrictive factor for economic healthy development. Environmental pollution reflects low-efficient utilization of resources and wrong development philosophy. People are gradually aware that national economic development should transform from pursuit of labor and capital efficiency to improving environment efficiency and resource utilization efficiency, and finally realize sustainable coordination between economy and environment. In the past, enterprises only use financial performance evaluation approaches to evaluate operation efficiency and effectiveness, which has gradually lagged behind the economic development requirements. Thus, it is necessary to develop a comprehensive index to unite economic benefits and environmental benefits. Eco-efficiency can measure enterprise and national economic performance and environment sustainable development ability, reflects the coordinated degree of economy, resources and environment.In nearly 30 years, China has achieved great economic achievements, but the economic development in our country is at the expense of high energy consumption, and has caused many environmental problems. The sustainable development of our country’s economy is subject to the contradiction between resource consumption and environmental protection. As the main body of market economy, the environmental problems in the process of management of listed companies have caused the wide attention of the society. More than 40% listed companies in our country had environment violation records in China, and most of those companies are the leaders in their industry, who have made great contribution to the local economic development, GDP growth and the achievements of local officials. Therefore, when the local environmental protection departments lack of tougher enforcement measures, those entperises are often undaunted to obtain more interests at the expense of the environment pollution. Ignoring the environmental consequences but also pursuing economic interests not only polluted the environment, and also endanger human health, damage the ecological environment, damage the enterprise social image, undermine its long-term competitive ability, as well as disrupt the stable social development paces. Therefore, modern listed company must consider environmental factors and ecological protection when making development strategy, actively measure environmental benefits, disclose environmental information, combine environmental protection and economic interests, convey positive signals to the market and investors, and optimize social image. At the same time, the government shall formulate normative documents to govern the environmental management of enterprise behavior. Eco-efficiency is the important method of sustainable development. Eco-efficiency organically unifies the economic performance and environmental benefits, reduce resource consumption, waste emissions and greenhouse gas emissions, and promote the maximization of economic value and social value.Non-ferrous metal mining, dressing and processing manufacturing industry is becoming more and more important in our country’s economic development. Government has made many policies to encourage non-ferrous metals mining and dressing to develop, but shortage of copper and other non-ferrous metal resources makes national non-ferrous metals mining and dressing industry dependent on imports in the long run. In addition, increasing cost of non-ferrous metal industry will further compress profit space of non-ferrous metal mining and affect the sustainable development. How to reform the traditional mode of production and business operation is an issue which China’s nonferrous metal industry needs to think about. Non-ferrous metal industry needs an eco-efficiency index system to evaluate operating performance and environmental performance.At present, eco-efficiency indicators are only used in in steel, petrochemical, and coal industry, and there is not yet eco-efficiency indicator in non-ferrous metal industry. Therefore, by constructing eco-efficiency index in X mining group, the paper hope to refine and expand the research fields of eco-efficiency to non-ferrous metal industry. Eco-efficiency indicators can be used for both transverse comparison (different enterprises in the same industry), can also be used in the longitudinal comparison (different stages of development in the same enterprise). Therefore, this article takes X mining group as an example to build the eco-efficiency indicators of non-ferrous metal industry, strengthen the comparability of environmental performance between different enterprises in non-ferrous metal industry, and provide comparable performance information for the same enterprise in different development stages. Ecological efficiency index system can provide reliable data for the evaluation of enterprise eco-efficiency, as well as help the enterprise management and stakeholders to analyze environmental impact on financial performance, environmental problems and financial problems in the company’s production and business operation, so as to help the management and stakeholders to make more scientific investment decisions. Based on eco-efficiency indicators put forward by WBCSD and environmental performance indicators proposed by "the agenda 21" and "the Montreal protocol" for reference, the paper establish environmental performance indicators of non-ferrous metal industry according to the characteristics of the non-ferrous metal production. Then the paper selects four financial performance indicators. Finally the paper builds the eco-efficiency index system of non-ferrous metal industry.This paper selects the X mining group as an object of case study. According to energy consumption and waste emissions data in environmental report of X mining group from 2013 to 2014, the paper calculates the environmental performance indicators based on environmental performance indicators proposed by "the agenda 21" and "the Montreal protocol"; According to financial data in theannual reports of X mining group from 2013 to 2014, the paper calculates its financial performance indicators. Finally, this paper calculates the eco-efficiency indicators according to the formula. Based on calculation results of eco-efficiency indicators, this paper finds that many factors have produced great influence on X mining group’s production and operation, including the slow recovery of overall global economy, the decreasing market demand, the slowing growth of domestic economy, the depressed non-ferrous metals market and so on. In order to breakthrough development bottleneck, X mining group needs to timely change investment decision-making, create more advanced production methods, reduce energy consumption and water consumption costs by advanced mode of production, reform the traditional business mode, and realize sustainable development.
