For Auditors

To achieve and maintain IWCA membership, a winery must regularly carry out Scopes 1-3 greenhouse gas (GHG) emissions inventories of its operations and have those inventories verified to the ISO-14064-1 standard.

IWCA works closely with ISO-14064-3 accredited auditors to:

ensure a robust standard and consistency in GHG measurement and accounting.
verify that wineries meet IWCA membership requirements and achieve consistent emissions reductions over time.

AUDIT SUMMARY FORM

The Audit Summary Form, to be filled out by ISO-14064-3 accredited auditors, is used to summarize an IWCA member or applicant member’s verified GHG inventory. The Form should be submitted to IWCA yearly (or every other year, depending on a winery’s size) to confirm that the winery meets IWCA membership requirements and is achieving ongoing emissions reductions.
