Sustainability Data Hub Architecture: Sources, Quality and Traceability

A sustainability data hub architecture makes it possible to trace where data comes from, how it is transformed, who approves it, and which report uses it. Without this structure, reporting processes remain dependent on individuals and file memory.

Architecture layers

• Source layer: ERP, meters, suppliers, HR, and operations systems.
• Collection layer: Forms, integrations, and controlled upload workflows.
• Quality layer: Missing data, outlier, and consistency checks.
• Calculation layer: Emission factors, conversion factors, and metric logic.
• Traceability layer: Evidence, versions, approvals, and audit records.

Design principle

Every data point should have a clear owner, source, update frequency, and control method. Sustainability data is not only collected; it is governed, validated, and made reusable.

Outcome

A strong data hub architecture improves reporting reliability and enables faster analysis across the organization.
