Scope 3 Supplier Data Collection
Replace your supplier emissions questionnaire with structured, validated data
Most businesses collect supplier emissions data by email: inconsistent formats, missing fields, no validation, no audit trail. GreenKPO's structured supplier survey portal collects Scope 3 data in a standardised, timestamped format that your auditor can rely on.
The problem with email-based supplier questionnaires
Most companies collecting supplier emissions data send a spreadsheet or a PDF form by email. The result is inconsistent: different suppliers interpret the same question differently, fields are left blank, units are mixed, and there is no way to validate what was submitted or trace it back to a source. When your auditor asks to see the supplier data behind your Scope 3 figure, you produce a folder of emails and hope for the best. GreenKPO was built to replace that process.
How GreenKPO's supplier portal works
GreenKPO's vendor data collection module sends structured survey invitations to your suppliers. Each supplier completes a standardised form with field-level validation: required fields cannot be skipped, data types are enforced, and the data quality classification between measured and estimated values is captured automatically. Every submission is timestamped, attributed to the supplier contact, and written to the KPOTrust immutable audit log. The result is a Scope 3 supplier dataset that is structured, traceable, and audit-ready from the moment the last supplier submits.
What you can do with the data
Once supplier emissions data is collected through GreenKPO, it feeds directly into your Scope 3 Category 1 (purchased goods and services) calculations. The combined output (your Scope 1 and 2 plus supplier Scope 3) is exportable as a complete carbon report aligned to GHG Protocol and SECR/UK SRS requirements. You present it to your auditor, your large client, or your procurement team without reassembling data from email threads.
