IIGF has independently developed a comprehensive and innovative “Green Evaluation System” to measure the green level of listed companies. The system includes qualitative indicators, quantitative indicators, and negative environmental protection behaviors. The “Green Evaluation System” has three major characteristics. Firstly, the indicator system involves both qualitative and quantitative indicators. Secondly, the indicator system emphasizes the company’s negative environmental protection behaviors. Thirdly, the evaluation system deducts ESG scores for companies within the “Two-Highs and One-Surplus” industries.
