Collection About esg certification
All rating agencies (certification agencies) have different evaluation methods. Some are "scoring system" and some are "evaluation system (qualified or unqualified)". The evaluation content (audit content) is also different, and the focus is different.
Compared with the relatively complete development of the international ESG rating system, the domestic ESG rating system is still in the initial exploration stage. Domestic ESG rating agencies are mainly universities and investment institutions. The ESG rating of colleges and universities is mainly represented by the China Finance and Green Institute, while the ESG rating system of investment institutions is mainly represented by the Commercial Road Ronglu, the China Securities Index and the Social Value Investment Alliance.
The main differences are:
（1） Indicator difference of ESG rating
Under the general framework of ESG concept, all ESG rating agencies have basically reached consensus on the core issues of ESG, namely environment (E) and society (S)
And corporate governance (G). However, only some of the secondary and even tertiary indicators detailed under the three core issues are rated by all ESG
Including indicators such as climate change, biodiversity, employment management, social welfare and board structure.
（2） Weight difference of ESG rating
Most of the major ESG rating agencies in the world use the weighting of the measurement index score to calculate the enterprise's ESG comprehensive score to obtain the enterprise's ESG rating. When ESG rating agencies have different opinions on different indicators or the importance of the same indicator in different industries, differences in weight will occur. Therefore, for different ESG rating agencies, the distribution of weights has become a key concern, and is also the main reason for ESG rating differentiation.
（3） Differences in the use of information disclosed by ESG
At present, there is no uniform ESG information disclosure standard in the world. Neither the corresponding regulatory authorities in the international market nor the domestic market have issued uniform, detailed and referential information disclosure standards. There are still many vague statements in most of the standards, leading to the fact that listed companies can only disclose information according to their own understanding of ESG.
Different emphasis and data channels of ESG information obtained by ESG rating agencies will also lead to differences in information measurement.
