Research On ESG Reporting Based On XBRL

Against the background of increasingly prominent environmental and social issues,the concept of ESG（Environmental,social,governance）has received more and more attention,and has become a hot spot in the political,theoretical and practical circles.ESG covers environmental,social,governance and many other aspects.Through the ESG information disclosed by the enterprise,its contribution to environmental protection,social responsibility and corporate governance can be assessed,thereby measuring the sustainable development value of the enterprise.ESG reports are the main form of ESG information disclosure,and are gradually becoming an important basis for evaluating the value of corporate sustainable development.However,judging from the current disclosure of ESG reports by domestic companies,the lack of a unified reporting standard has led to the cluttered content of ESG reports issued by many companies,the lack of information value,and the report form based on text description is not conducive to users’ efficient access to information.It brings difficulties to the process of querying and collecting data for users.Therefore,how to promote the standardization of ESG reports of domestic listed companies has become an important issue in the current field of ESG information disclosure.In response to this problem,based on the standardization theory,this paper constructs an indicator system for ESG reports,and finally uses XBRL technology to prepare ESG reports,and analyzes in detail the process of expanding the classification standards of domestic listed companies to generate ESG report instance documents based on cases.The research ideas of this paper are as follows: first,analyze the problems existing in the current ESG reporting,and propose solutions to promote the standardization of ESG reporting;then construct the indicator system of ESG reporting in my country,and then construct the XBRL classification standard according to the established ESG reporting indicator system;Taking Baosteel Co.,Ltd.as an example,an example document of ESG report is generated through the expanded XBRL taxonomy,and finally the research process is summarized and suggestions are put forward.This article refers to the guidelines issued by the Hong Kong Stock Exchange and the conceptual framework of sustainable development issued by the SASB organization to determine the content of the ESG report,explaining that the main part of ESG is based on the three dimensions of environment,society and governance.Indicators,the granularity is from coarse to fine to disclose the content of the report.The appendix is a supplementary description of some related situations.In Chapter 4,this paper builds the XBRL general taxonomy for ESG reporting,explains in detail the architectural models and schema documents used,defines the elements under the general taxonomy,and compiles a link library file to illustrate the XBRL taxonomy Structure.The fifth chapter takes Baosteel Co.,Ltd.as an example,expands the XBRL classification standard according to the characteristics of enterprises and industries,and generates example documents by manual input,and makes an explanation.This paper discloses ESG information through XBRL,which innovates the release and use of ESG reports,which can effectively improve the utilization efficiency of ESG reports,provide convenience for analysts,and has certain research significance.The conclusions and recommendations of this paper are as follows:（1）Countries should unify ESG reporting standards and establish standardized ESG reporting standards for reference by various companies.（2）Theoreticians should pay attention to the research on the application of XBRL in the field of business reporting,and expand the scope and depth of application.In view of the current lack of XBRL taxonomy applied to ESG reporting in my country,experts proficient in XBRL technology and experts proficient in sustainable development need to work together to build an ESG reporting system based on XBRL.
