Matching names and units do not establish applicability. Check the following and record why you chose a factor.
Before you decide
Units and product specifications
Match your activity unit to the factor’s reference unit, then check the actual product, manufacturer and specifications.
Included and excluded processes
Check the source for coverage of raw materials, manufacturing, transport, use and disposal. A product name does not establish its system boundary.
Reporting purpose and applicability
A dataset edition is not a certificate validity period. Check your reporting purpose, applicable rules and original conditions. Newer or lower does not automatically mean suitable.
This example does not establish factor suitability or a product footprint. Carop supports PCF and LCA methodology questions; automated product PCF and LCA calculations are not available.
