B2B Carbon Disclosure 101: Product Carbon Footprint (PCF) for Suppliers

Learn Scope 1/2/3 emissions, Product Carbon Footprint (PCF) under GHG Protocol & ISO 14067, and how disclosure wins EU buyers under CSRD.

Why disclosure matters

Under CSRD, EU companies with > 250 employees must report supplier-level emissions starting FY2025. They will only buy from suppliers who can disclose.

The 3 scopes

What is PCF?

Product Carbon Footprint = total GHG emissions per functional unit of a product (kg CO₂e per tonne, per unit, per kWh).

Calculated under GHG Protocol Product Standard or ISO 14067.

How to start

  1. Define your functional unit
  2. Map life-cycle stages (cradle-to-gate is minimum)
  3. Collect activity data (energy, raw materials, transport)
  4. Apply emission factors
  5. Calculate and document
  6. Verify (third-party recommended)
  7. Disclose on product pages and invoices
