# Use supplier PCFs

> Add supplier footprints to inventory and choose them for purchases or BOM inputs.

Open **Supplier PCFs** in the sidebar.

| Tab | What you find there |
| - | - |
| Inventory | PCFs already added to your organization, including PCFs shared in response to requests. |
| Public library | Public PCFs you can review and add to your inventory. |

<Steps>
  <Step title="Add a public PCF if needed">
    In **Public library**, find the appropriate product and supplier. Check the year, emissions unit, and company identity, then use **Add to inventory** from the PCF's actions.

    </Frame>
  </Step>

  <Step title="Choose the PCF on the record">
    Create or edit the purchase or BOM input and select the upstream PCF in its emission-factor picker. A supplier name alone does not attach a PCF.
  </Step>

  <Step title="Check quantities and units">
    Match the input quantity unit to the PCF denominator. If a conversion is required, enter the equivalent quantities supported by your product data. Review the saved estimate used as a fallback where the form provides one.
  </Step>

  <Step title="Review linked purchases">
    In **Supplier PCFs → Inventory**, open the PCF's actions and select **View linked purchases** to see the purchase connections.
  </Step>
</Steps>

**Remove** hides a PCF from your inventory. Existing purchase and supply-chain connections continue to use it, and historical calculations are retained. It does not delete the supplier's PCF.

Live calculations can change when the supplier updates its PCF or your access changes. Use a [snapshot](/user-guides/pcfs/versions-and-snapshots) when you need a fixed report value.

If the required PCF is not available, [request it from the supplier](/user-guides/supplier-engagement/request-a-pcf).
