Research question
A board EPD can show a negative product-stage total while fossil emissions and later biogenic release remain visible. Reading only one cell loses the lifecycle structure.
A worked project scenario
A team proposes a 16 mm paperboard counter and notices the negative A 1-A 3 total for All White. The counter also has printed faces, fasteners and a return journey, none of which is established by that single board value.
Method to use
Keep fossil, biogenic, land-use and total indicators visible. Record the declared board area and exact variant. Add project printing and logistics separately. Show end-of-life scenarios alongside the product stage and preserve module D outside the system boundary.
Limits of the conclusion
The declaration models later processing and release. It does not demonstrate the actual counter’s recovery or establish a climate-neutral claim.
Questions for the actual application
- Which exact source, unit and version support the decision?
- Which project quantities are measured, and which remain assumptions?
- What could change the result after installation or recovery?
Scope and limitations
- The declaration models later processing and release. It does not demonstrate the actual counter’s recovery or establish a climate-neutral claim.
