What information should I declare to perform a proper LCA?
Even if a certain amount of data can be assumed, there is a minimum rate of information required to perform an LCA. All the information used to perform the LCA is defined as mandatory data. Only a part of the mandatory data can be substituted by an assumption from BCome methodology. Each analysis has a max assumption rate based on the data for which a standardized assumption is available. To sum up, the type of required data is divided between:
- Mandatory (M): Mandatory data to be filled in to be able to make the calculation.
- Mandatory, assumption allowed (M-A): Mandatory data to be filled on which an assumption can be made according to BCome methodology.
To obtain accurate and precise results for the LCA product, follow the data summary below.
| Scope | Type of information required |
|---|---|
| Articles | – Name and reference Mandatory – Units produced Mandatory (assumption allowed) – Manufacturing supplier name Mandatory – Category to which the product belongs Mandatory – Materials used (parts) Mandatory – Item’s weight Mandatory – Weight of each material within the article Mandatory (assumption allowed) – Article finishings (dye process, treatment process, print process) Mandatory (assumption allowed) – Manufacturing losses (%) Mandatory (assumption allowed) – Share offline/online sales Mandatory (assumption allowed) – Packaging for online & offline sales Mandatory (assumption allowed) |
| Materials | – Material name Mandatory – Material reference Mandatory (assumption allowed) – Category Mandatory – Composition percentages Mandatory – Composition names Mandatory – Origins of raw materials Mandatory (assumption allowed) – Material finishings (dye process, treatment process, print process) Mandatory (assumption allowed) – Material processing supplier name Mandatory (assumption allowed) – Raw material extraction suppliers’ names Mandatory (assumption allowed) – Material processing losses (%) Mandatory (assumption allowed) |
| Suppliers | – Manufacturing supplier name Mandatory – Country of manufacturing origin Mandatory – Country of material processing origin Mandatory (assumption allowed) – Country of raw material extraction origin Mandatory (assumption allowed) – Manufacturing transport used Mandatory (assumption allowed) – Material processing transport used Mandatory (assumption allowed) – Raw material extraction transport used Mandatory (assumption allowed) |
| Corporate | – Tertiary and secondary packaging Mandatory (assumption allowed) – Distribution center Mandatory |
| Retail packaging | – Packaging name Mandatory – Packaging reference Mandatory – Type Mandatory |
