What Is a Bill of Materials?
Your bill of materials is a detailed list of all inputs — materials, components, energy, and processes — required to make one unit of your product. Your BOM information likely exists across multiple places in your organisation: product design documents, your procurement system, manufacturing specifications, supplier datasheets, and cost accounting records.
Product UUIDs and Identifiers
Each product in Green Project gets a unique identifier (UUID) to track it accurately and prevent duplication. Different versions of the same product get different UUIDs, and customers can trace their purchases back to the relevant PCF. When you set up a product, you provide a name and internal SKU, and Green Project assigns the UUID.
Controlling Access to Your BOM
Your detailed bill of materials may contain proprietary information. When you share a PCF with a customer, they see the total emissions and breakdown by lifecycle stage — not your detailed materials or supplier names. The BOM remains your intellectual property.
When you update your product or sourcing, revise the BOM in Green Project, recalculate your PCF, and the new version becomes active while historical versions are retained for trend analysis.
