Enter the material you plan to use. You get its sustainability report card, the rules to check, and better alternatives for the same job, with the trade-offs spelled out.
Try plastics and foams:
Natural and bio-based:

Pick the closest match. The grade decides the figures.
Newer materials with a similar profile. Their figures are less established: ask the company for data.
Check whole parts lists, see product totals and hotspots, try swaps, and open every material's full data sheet.

Paste your parts list. You get the product's material carbon, the parts that matter most, the rules to check, how recyclable the mix is, and better options for each part, with the new total as you swap.
One part per line: part name, material, weight and (optional) quantity. Copy straight from a spreadsheet or a CAD parts list; commas, semicolons or tabs all work, and a header row is recognised.
Each material is matched to the closest grade in the database. Correct any line marked “check”; your choices are remembered for next time.
Open “Suggested alternatives” on a part to see better options; “Use this” updates the totals above.
This is a materials screening: the carbon covers raw materials to the factory gate, using typical figures for generic grades. Manufacturing is added only for parts where you choose a process (energy for that step, gate to gate). It leaves out transport, use and end of life, so it is not a life-cycle assessment or an EPD.
