| chapter | Explanation of the differences |
| 4. Application | Adjust text and align with ISO14026 communication requirements |
| 5. Principles | (1) Corresponding - Functional Unit (CFP)/Declaration Unit (Partial CFP) |
| (2) Delete 5.13 Participation & 5.14 Fairness |
| 6. Quantitative Methods | 6.1 New Reference Guidelines for Systematic Quantification of Carbon Footprint (Annex C) |
| 6.2 PCR reference standard changed to ISO/TS14027; 6.2.2 PCR content deleted |
| 6.3.3 Added declaration unit; declaration unit is only used for Partial CFP. If the omitted stages are the same, Partial CFP can be used for B2B product comparison |
| 6.3.5 Add a data quality assessment process. The four aspects of data, such as time boundary, geographical boundary, technicality, and accuracy, need to be characterized in carbon footprint research. |
| 6.4.6.1 (Allocation) When product category rules have been developed in accordance with ISO/TS14027, sensitivity analysis regarding allocation should not be performed. |
| 6.4.8 Modify the description of the time impact of the use phase/final disposal phase; if the use phase/final disposal phase occurs 10 years after the product is manufactured, the time impact must be specifically stated in the carbon footprint report. If calculated, it must be documented and reported separately. |
6.4.9.2
a. Fossil carbon emissions and removals (e.g. carbon capture and removal (CCS)) should be included in the carbon footprint calculation and reported separately as net emissions (Net results).
b. Biomass carbon emissions and removals should be included in the carbon footprint calculation and reported separately, including emissions from the biomass carbon planting/production/harvest process. |
| 6.4.9.3 Modify ISO/TS14067 6.4.9.6 Carbon Storage Description; Product biomass carbon storage effect is calculated in accordance with 6.4.8 |
| 6.4.9.4 Modification of power processing method |
| 6.5 New Carbon Footprint Impact Assessment can use different GWP annual ranges (e.g. GWP-500) or GTP, but must be reported separately |
| 7. Research Report | Chapter simplification adjustment |
