Audit trail and filters

Audit trail: a searchable change log

Review what changed, who changed it, and when—without relying on spreadsheets.

February 26, 2026 4 min read

The audit trail gives your organisation a time-stamped, searchable record of activity in the offset ledger. It supports reviews, internal controls, and evidence-led climate reporting by showing what changed on a certificate and who made the change.

What the audit trail shows

Each audit event is listed with a change type, a certificate reference, the user (or system) that performed the action, and when it happened. If an event includes field updates, you will see a clear “from → to” breakdown for each changed field.

  • Change types: Examples include purchase created, payment completed, certificate created, and allocation updated.
  • Field-level diffs: Allocation changes can include cost center, project code, business unit, scope category, tags, status, and comments.
  • Most recent first: Events are sorted by newest activity, with pagination for longer histories.

How to search and filter

Use the search box to find events by certificate, project, business unit, user, or keywords related to the change. To narrow down further, use the change type filter to focus on a specific class of events.

This is especially useful when you are reconciling a report: you can quickly find when an allocation was updated, confirm the previous value, and identify who applied the change.

Access and permissions

Audit trail access is permission-gated. If you do not see the page, ask your organisation admin to update your role.

If you integrate via the API, you can include allocation fields (cost center, project code, business unit, and scope category) at creation time. Those updates are visible in the audit trail, so reporting and integrations stay aligned.
