For Auditors
Comprehensive GHG Emissions Accounting
To achieve and maintain IWCA membership, a winery must regularly carry out Scopes 1, 2, and 3 greenhouse gas (GHG) emissions inventories of its operations.
To ensure a consistent high standard, we require that inventories be verified to the ISO-14064-1 standard.
IWCA works closely with ISO-14064-3 accredited and CDP 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.
IWCA Resources & Documentation
IWCA Audit Summary Form
PURPOSE: To summarize an IWCA member or applicant member’s verified GHG inventory.
​
The Audit Summary Form is to be filled out by ISO-14064-3 or CDP accredited auditors. 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.
GHG Emissions Inventory Guidance
PURPOSE: Outlines the protocols all IWCA members must follow when measuring their GHG emissions.
​
IWCA's GHG Inventory Scopes Guidance Document outlines the categories of emissions that must be accounted for under a comprehensive Scopes 1, 2, and 3 inventory.
