《GB/T 42663-2023钢铁行业水足迹评价要求》由TC183（全国钢标准化技术委员会）归口，TC183SC2（全国钢标准化技术委员会基础分会）执行，主管部门为中国钢铁工业协会。
Introduction
1. Background and significance of the standard
GB/T 42663—2023 "Requirements for Water Footprint Assessment in the Iron and Steel Industry" is my country's first water footprint assessment standard for the steel industry, aiming to standardize water resource management and environmental impact assessment within the industry.
Keywords: GB/T 42663, steel industry, water footprint assessment
2. Comparative analysis of standard frameworks
| Standard Dimensions | GB/T 42663—2023 | International Reference Standard |
|---|---|---|
| Scope of Application | Only applicable to the independent implementation and reporting of water footprint assessments in the steel industry. | International standards such as ISO 14046 apply to all industries. |
| Data collection priorities | Primary data > Secondary data | International standards do not specify data priorities. |
| Evaluation indicators | Core indicators such as water scarcity footprint and water degradation footprint. | Includes all stages of the product life cycle (cradle to grave). |
3. Interpretation of key technical points of the standard
Keywords: Water footprint calculation method, Pollutant characterization factor, Water footprint of steel enterprises
3.1 Calculation of water scarcity footprint
According to the formula: $$ W F_{\mathrm{sc,p}}=\sum_{y=1}^{n}{\frac{WS I_{z}}{WS I_{\mathrm{gl}}}}\times C_{z} $$ Wherein, $WS I_{z}$ is the regional water resource pressure index, refer to Table B.1.
4. Implementation suggestions
- Data collection and management:Primary data should be used first, and a sound data review mechanism should be established.
- System boundary definition:Choose an appropriate system boundary (such as "cradle to gate" or "gate to gate") according to the needs of the enterprise.
- Application of characterization factors:Refer to the pollutant characterization factors in Table B.2 to ensure the accuracy of the evaluation results.
- Report preparation:In accordance with the requirements of Appendix C, ensure that the report content is complete, transparent and operational.
