Introduction
Analysis of the core content of the standard
Evaluation principle system
| Principles | Technical requirements | Implementation points |
|---|---|---|
| Life cycle perspective | Covering the entire process from raw material acquisition to waste disposal | A system boundary flow chart needs to be drawn |
| Iterative method | Five-stage cycle optimization | A dynamic adjustment mechanism needs to be established |
| Transparency | Data source and methodology disclosure | Uncertainty analysis needs to be attached |
| Science priority | Use internationally accepted methods such as ReCiPe | Characterization model needs to be explained |
Implementation of the methodological framework
Five-stage assessment process
- Purpose scope determination: clarify the functional unit (e.g. "1 mobile phone is used for 2 years")
- Environmental impact assessment: adopt GB/T 24044 life cycle assessment method
- Value assessment: quantify the functional value with QFD model
- Eco-efficiency quantification: establish a ratio relationship model
- Result interpretation: include sensitivity analysis report
Smartphone assessment example
Take business smartphone as an example:
- Environmental performance: 6.76 Pt (based on ReCiPe method)
- Product value: 1.98 min·a (calculated through 16-characteristic QFD matrix)
- Eco-efficiency: 0.29 min·a/Pt
Key technical requirements
System boundary delineation
| Life cycle stage | Included elements | Data requirements |
|---|---|---|
| Raw material stage | Resource extraction, component manufacturing | Need to include transportation energy consumption |
| Production stage | Assembly, packaging process | Distinguish production line differences |
| Use stage | Charge and discharge characteristics | Measured standby power consumption |
Value assessment method
Note when using the Quality Function Deployment (QFD) model:
- Consumer demand weights are determined through market research
- Qualitative indicators (such as materials) require quantitative rules
- Appendix A of the standard provides a laptop evaluation template
Implementation recommendations
- Establish a cross-departmental LCA database
- Develop product characteristic quantification tools
- Perform sensitivity testing regularly (≥3 scenarios are recommended)
Note: When issuing a comparative statement to the public, an expert appraisal review must be performed
