Question 1

What is a product carbon footprint?

Accepted Answer

A product carbon footprint (PCF) is the total greenhouse gas emissions generated by a product across its defined life cycle, expressed in CO₂ equivalent (CO₂e). It can cover raw material extraction, manufacturing, transport, use, and end-of-life — depending on the chosen system boundary.

Question 2

What standard governs product carbon footprint calculation?

Accepted Answer

ISO 14067 is the primary international standard for product carbon footprint quantification and communication. It is consistent with ISO 14040 and ISO 14044 (lifecycle assessment standards) and the GHG Protocol Product Standard.

Question 3

What is the difference between a product carbon footprint and a full LCA?

Accepted Answer

A product carbon footprint focuses exclusively on greenhouse gas emissions (GWP — Global Warming Potential). A full lifecycle assessment (LCA) covers all environmental impact categories including water use, eutrophication, land use, and ecotoxicity in addition to carbon.

Question 4

How does Weafs calculate product carbon footprint?

Accepted Answer

Weafs integrates with your ERP and BOM data, maps materials to our global LCA dataset using AI, calculates Scope 1, 2, and 3 emissions per the ISO 14067 methodology, identifies the highest-impact hotspots, and generates audit-ready carbon footprint reports — all automatically.
