c) Enterprises can improve product manufacturing processes by adjusting and optimizing raw materials and applying breakthrough production processes that can replace carbonate raw materials. Carbon reduction;

5.3 Quantitative Evaluation Indicators

5.3.1 The quantitative evaluation indicators are the greenhouse gas emission intensity per unit of product output and the reduction rate of total greenhouse gas emissions at the enterprise level.

5.3.2 Greenhouse gas emission intensity per unit product output is calculated according to formula (1).

5.3.3 The reduction rate of total greenhouse gas emissions at the enterprise level is calculated according to formula (2).

6.1 Qualitative Evaluation

6.1.1 The qualitative evaluation section has a total score of 40 points, determined by the sum of the scores of each qualitative evaluation indicator. Secondary indicators can be assigned according to different categories of building materials. Scoring is assigned based on the evaluation requirements set forth below.

6.1.2 When a qualitative evaluation indicator is not applicable, that indicator shall be scored as 0 points and deducted from the total score of the qualitative indicators. The total score of the qualitative index T1 is then corrected by multiplying it by the normalization coefficient eta, which is calculated according to formula (3).

6.2 Quantitative Evaluation

6.2.1 General Provisions The quantitative evaluation section has a total score of 60 points, consisting of the greenhouse gas emission intensity index per unit of product output and the greenhouse gas emissions at the enterprise level. The score is determined by summing the scores of the total reduction rate and the energy consumption per unit of product. Among these, the greenhouse gas emission intensity per unit of product output is... The total score is 40 points, with 20 points allocated to the enterprise-level greenhouse gas emission reduction rate indicator. When a quantitative evaluation indicator is not applicable, refer to...

6.1 The total score of the quantitative evaluation index is adjusted by the normalization coefficient.

6.2.2 Calculation of Greenhouse Gas Emission Intensity Index Score per Unit Product Output A score of full marks is given for greenhouse gas emission intensity per unit of product output that is superior to advanced levels during the evaluation period, while a score of 0 marks is given for failing to meet the benchmark. If... The score between the advanced value and the benchmark value is calculated according to formula (4). Greenhouse gas content per unit product of cement, flat glass, building ceramics, and sanitary ceramics. Advanced and benchmark values for emission intensity are shown in Table B.1 of Appendix B. For emissions intensity excluding cement, flat glass, building ceramics, and sanitary ceramics... For production enterprises, the benchmark value is the top 50% level of greenhouse gas emission intensity per unit of product in the corresponding industry, and the advanced value is the greenhouse gas emission intensity per unit of product in the corresponding industry. The top 20% level of indoor gas emission intensity.

6.2.3 Calculation of the score for the enterprise-level greenhouse gas emission reduction rate indicator If the total greenhouse gas emission reduction rate delta at the enterprise level is greater than or equal to 5%, T2-2 is scored as 20 points; if it is less than or equal to 0, T2-2 is scored as 0 points. When the percentage is greater than 0% and less than 5%, T2-2 is calculated according to formula (5).

8.1 Evaluation Initiation

8.1.1 Enterprises shall conduct self-assessments or entrust a third party to conduct low-carbon enterprise assessments.

8.1.2 Develop an evaluation work plan, which should include the evaluation purpose, evaluation criteria, evaluation scope, and evaluation activity schedule.

8.1.3 Establish a review panel to be responsible for the specific evaluation work. The review panel members should ideally include experts in the low-carbon field of the building materials industry, and the number should be substantial. There are 3 people, one of whom serves as the group leader.

8.2 Evaluation Implementation

8.2.1 Document Review The review panel should conduct a preliminary review of the application materials and self-evaluation results provided by the company to determine whether it meets the requirements stipulated in Chapter 4. Evaluation criteria were established, and key aspects requiring focus during on-site evaluation were identified.

8.2.2 On-site evaluation The on-site evaluation includes the following.

---Meeting will be held. Both sides will introduce their personnel and finalize the evaluation work plan, etc.; the company will introduce its basic information and related low-carbon construction. Results;

---Review of application materials. Application materials should include a basic introduction of the enterprise, the enterprise's low-carbon construction implementation plan, implementation results, and carbon emission standards. Released statistical information and relevant supporting documents;

---Interviews with relevant personnel;

---On-site inspection of relevant facilities;

---Hold a summary meeting. The review panel will communicate with the head of the applicant organization to identify and confirm the review findings. The review panel leader will then present the findings of the review.

9.Evaluation Report The review panel prepares an evaluation report. See Appendix C for an example of an evaluation report outline.
