What Audit-Ready Documentation Looks Like for Commodity EACs

Audit-ready commodity EAC documentation should make it clear what was produced, what was issued, who owned it, when it was retired, and what claim it supports.

Why documentation is the product

In commodity EAC markets, the certificate is only as credible as the documentation behind it.

Buyers need to know what they purchased, what it represents, where it came from, whether it was retired, and what claim it can support. Producers need clear records showing how their environmental attributes were issued and used.

Recommended documentation elements

Documentation elementPurpose
Production recordShows the underlying eligible production or service activity.
Certificate metadataIdentifies certificate quantity, vintage, commodity, producer, and relevant attributes.
Issuance recordShows when certificates were created and linked to eligible production.
Transfer historyShows how certificates moved between parties.
Retirement confirmationShows that certificates were permanently removed from circulation for a defined buyer and purpose.

What buyers should ask before purchasing

Buyers should ask whether certificates are serialized, what production they are linked to, what documentation will be provided, whether retirement is permanent, and what claims guidance is available.
