Introduction
Analysis of the core content of the standard
| Key elements | ISO 14067:2018 | GB/T 24067-2024 |
|---|---|---|
| System boundary | Basic requirements for the entire life cycle | Add geographic grid division rules, and strengthen spatial dimension data association |
| Data quality | Primary/secondary data classification | Clearly define the upper limit for discarding (single item <1%, cumulative <5%), and add time boundary specifications |
| Biogenic Carbon Treatment | Distinguishing between Fossil/Biogenic Sources | Appendix E details the calculation method for changes in carbon storage of agricultural and forestry products |
Technological Evolution and Innovation
1. Geographic Boundary Quantification: The standard first proposed the concept of geographic grid unit, requiring that unit process data must be associated with the actual geographical location (such as provincial/county administrative regions) to enhance the spatial traceability of carbon footprint.
2. Power Processing Specifications: Added clause 6.4.9.4 to distinguish the carbon emission calculation rules for internal power generation, direct power supply and grid power, and requires that contract energy provide generator unit characteristic information.
Implementation Suggestions
- Enterprises should establish a product carbon footprint system method (Appendix C) and unify data collection and distribution procedures
- Prioritize the use of industry PCR rules. When there is no PCR, refer to the framework of Appendix H to formulate a quantitative method
- Focus on the control of raw material acquisition (average contribution 40-70%) and energy use (15-30%) stages
Typical application scenarios
Case: Carbon footprint of photovoltaic modules: field data is required for silicon material production (52%), module assembly (18%), transportation (7%) and other stages, and secondary data can be applied to secondary components such as inverters.
Special Tips: The standard explicitly excludes carbon offset mechanisms (3.1.7). If an enterprise uses renewable energy quotas, it must report separately.
