Description
Technical Field
The application relates to the technical field of data processing, in particular to a method and a device for evaluating the green grade of an enterprise based on carbon efficiency.
Background
Under the carbon peak carbon neutralization background, the enterprise green grade evaluation based on carbon efficiency has more and more demands in the enterprise green low-carbon high-quality development work. Carbon efficiency is generally used to characterize carbon productivity, which refers to the economic output level of a unit of carbon dioxide emission of an enterprise, such as GDP or product yield per unit of carbon dioxide emission produced by the enterprise. At present, the comprehensive green evaluation of enterprises takes an enterprise environment, society, management (ESG) rating system and enterprise carbon performance as representatives, and the sustainable development performance of the enterprises and organizations is measured. The ESG rating system is based on three dimensions of environment, society and governance, and specific indexes of subdivision are designed according to the characteristics of the industry where an enterprise is located, so that the ESG index system and the rating method are formed. The establishment of an enterprise ESG rating system requires a large amount of data support, and meanwhile, the ESG quantitative and qualitative data of enterprises and public opinion penalty information and the like need to be collected. The ESG rating index systems adopted by international mainstream ESG rating organizations are different, such as an MSCI ESG rating index system, a Rich Timentin ESG rating index system, a Toxon road penetration ESG rating index system and the like, and the rating index systems are respectively refined from three dimensions of environment, society and treatment to a second level index, a third level index and a fourth level index layer by layer. The secondary indexes under the environmental dimension are generally classified into environmental management, climate change, emission management and the like, and the weight of an index system is determined by adopting a statistical average method (an expert scoring method), an analytic hierarchy process and the like. The carbon performance of the enterprise is developed from the performance evaluation of the enterprise, and the carbon performance is expanded to the environmental field in performance evaluation index systems such as financial indexes of a DuPont analysis system and balance scorecard of carplan, so that an evolution path of a 'single technical index-fusion index-index system' is formed. However, the international survey report of enterprise sustainability published in 2010 by the bimawal accountant institute indicates that only about 3% of companies report on the carbon performance fusion level, and most companies only combine the sustainable reports and the financial reports, so that the economic impact of carbon emission reduction activities on the enterprises cannot be known, and whether the enterprises achieve improvement of carbon efficiency by means of technical means and the like cannot be judged. With the development of carbon performance index systems, there are various carbon performance rating systems such as index systems which integrate carbon strength, carbon dependence, carbon disclosure and carbon risk, and index systems which deviate from low carbon levels, sustainability of low carbon levels, and low carbon activity. In summary, the existing methods for evaluating the greenness of an enterprise include an ESG evaluation method and a carbon performance evaluation method:
for the ESG evaluation method, firstly, the carbon effect influence is too low in the evaluation result, the evaluation result comprises three dimensions of environment, society and treatment, the indexes related to carbon emission are only used as a small part of the indexes of the influence of climate change in the environment dimension, even if weight adjustment and index system subdivision exist, the final evaluation result is difficult to reflect the carbon effect condition of an enterprise in a key way, and the result obtained by the ESG evaluation method is difficult to obtain when the government, financial institution or enterprise needs to evaluate the green low-carbon development condition of the enterprise under the double-carbon background, so that the influence of the carbon effect condition change of the enterprise on the green color of the enterprise is accurately captured; secondly, the coverage of indexes related to carbon efficiency is relatively limited, and the existing ESG evaluation method only generally comprises indexes such as carbon emission, carbon strength and the like, so that the carbon efficiency change of an enterprise is difficult to be comprehensively reflected; thirdly, the ESG evaluation method is not strong in applicability for evaluating the greenness of enterprises, needs to disclose a large amount of environmental information and enterprise related information, and can well meet the disclosure requirements only by large enterprises such as listed companies, so that the evaluation method is difficult to have good universality and accuracy.
For the carbon performance evaluation method, firstly, the carbon performance evaluation index lacks wide applicability, and the carbon performance index formed by refining the existing national level evaluation index does not consider the difference of industrial production and the operability of enterprises, so the research results are possibly suitable for external green evaluation but not suitable for internal evaluation of enterprises; secondly, the selection of the carbon performance evaluation indexes has certain randomness, and when an index system is designed, due to the lack of practical data, the information quantity provided by each index is difficult to be fully considered, and the acquirability of the indexes is difficult to be ensured; thirdly, whether the carbon efficiency of an enterprise is proper is reflected by using financial indexes, a large dispute still exists in the academic world, and the existing performance evaluation model is not suitable for the carbon performance, so that the accuracy of the carbon performance evaluation method result is questioned.
In summary, both the ESG evaluation method and the carbon performance evaluation method generally have a problem of low evaluation accuracy.
