Assessment scope

Carbon of reused content (GCP indicators)

For the GCP's potential GHG savings: the share of the new-material carbon figure charged to reused content and the kept part of remanufactured content. 0% follows the GCP's cut-off (reused material carries no production burden). Enter a share if refurbishment, transport or repair is significant, and keep the evidence.

% of the new-material figure

Build a bill of materials for a product, then see its circularity (%MCI) and its three parts, per component and for the whole product. Every figure is calculated by the Hoskins engine as you type; nothing you enter is stored on the server. Save your project as a file to keep it.

Projects are saved as files on your computer. Unsaved work is also kept as a draft in this browser in case the tab is closed, but that is not a backup. A list of your saved projects arrives with accounts.

Not built yet.

Planned: a register of supplier parts with their own declared figures and evidence, so a line can start from a supplier's part instead of a generic material.

Nothing in the calculator depends on this yet.

Not built yet.

Planned: sign in with an emailed link (passkeys after that), keep projects on the server, and share them with colleagues and clients. Until then you work without an account and nothing is stored on our servers.
