Scope 3 Emissions Reporting: From Supplier Data to Audit-Ready Reports

The Shift to Primary Data

For years, companies relied on spend-based estimates and industry averages to calculate their Scope 3 emissions. As regulations tighten and stakeholders demand transparency, estimates are no longer acceptable. The mandate is clear: you need primary data directly from your suppliers.

The Auditability Gap

Even when companies collect primary data, it often lives in disconnected spreadsheets without a clear trail of evidence. When auditors ask for the source of a specific emission figure, finding the original invoice or declaration is nearly impossible.

Audit-Ready by Default

Emissio bridges this gap by making every data point traceable. Every figure extracted from a supplier is permanently linked to the original document (the invoice, the register, the photo). If an auditor questions a calculation, the underlying evidence is just one click away.
