(stock abbreviation: Tongling Nonferrous, code: 000630.SZ) had its Wind ESG rating upgraded from BBB to A. The company's overall score is 7.45, higher than the average score of 6.07 in the metals and mining industry. It ranks 35th among 191 companies in the industry, placing it in the top 18.32%. The scores for the environmental, social, and governance dimensions are 6.10, 6.39, and 8.03, respectively. Compared to the previous rating, the overall score increased from 6.32 to 7.45, an increase of 1.13 points. Specifically, the score for management practices improved from 3.32 to 4.68, an increase of 1.35 points; the score for controversy events decreased from 3.00 to 2.78, a decrease of 0.22 points. In terms of dimensions, the environmental score increased by 1.81 points, the social score increased by 2.26 points, and the governance score increased by 1.76 points. ## Rating Observation In the environmental dimension, the company demonstrated multi-level practical capabilities from system certification to waste and wastewater management. The company has obtained ISO 14001 environmental management system certification and established a standardized control system covering the entire process of hazardous waste, achieving a 100% hazardous waste disposal rate. During the reporting period, the total amount of non-hazardous waste generated by the company was 11.35 million tons, corresponding to 6,571.11 tons per 100 million in revenue; the total amount of hazardous waste was 35,000 tons, corresponding to 20.24 tons per 100 million in revenue. In terms of wastewater management, the company significantly reduced emissions through closed-loop circulation and resource utilization measures, with a wastewater discharge of 14.03 million tons during the reporting period, corresponding to 81.25 tons per 100 million in revenue. Additionally, the company is promoting the upgrading of wastewater treatment facilities and the reuse of reclaimed water, with underground drainage volume reduced by 720,000 tons year-on-year in the first 10 months before 2025, saving over 2.8 million yuan in costs. The company collaborates with suppliers to optimize raw material design for waste resource utilization, but the quantitative data disclosure regarding the total amount of recycling and utilization of waste and exhaust management, as well as target setting, still needs improvement. In the social dimension, the company has demonstrated strong management capabilities in occupational health and safety production, while also reflecting care in the employment sector through employee satisfaction surveys and assistance measures for those in difficulty. The company and its affiliated units have obtained certification for occupational health and safety management systems and have established multiple internal systems to solidly promote fundamental safety production actions. The incidence of occupational diseases and work-related deaths is zero, with an injury rate of 0.0541%, and safety production investment reached 267 million yuan, accounting for 0.155% of operating income. In the employment sector, the company's employee satisfaction is above 90 points, and a systematic survey mechanism has been established for policy optimization, while a total of 4.67 million yuan has been donated for assistance to employees in difficulty, with 16,300 yuan provided as living subsidies for orphaned individuals. The company still has room for improvement in gender diversity, with the proportion of female employees at 15.63%, and the proportion of female executives has not been disclosed In terms of governance, the company demonstrates a strong checks and balances mechanism through the proportion of independent directors and the independence of committees, while also reflecting its governance commitment in the anti-corruption field. The proportion of independent directors on the board is 37.5%, with no independent directors serving terms exceeding 6 years or 9 years, and the CEO does not concurrently serve as the chairman. The audit committee is composed entirely of independent directors, with the chairman being an independent non-executive director, and the compensation committee and nomination committee both have 66.67% independent directors. The company has established an anti-corruption management system, with the board fulfilling its highest supervisory responsibilities, and strengthening governance through diversified reporting channels and strict whistleblower protection measures. In 2025, the company conducted 3 training sessions for all discipline inspection cadres, organized 14 batches with 341 participants for legal training, and included business partners in the anti-corruption training scope. The proportion of female executives is 0%, indicating that there is still room for improvement in terms of diversified governance.
