Audit Page
Last updated: 10 April 2026
The Audit Page is the final verification checkpoint for your carbon inventory. It shows every transaction with full calculation detail — emission factors, confidence scores, source files — and lets you filter, edit, and export the data for auditors. Navigate to Analyse > Audit Page.
What Each Row Shows
Each row is a single transaction or data entry in your carbon inventory. By default, the table shows:
- Date — The transaction date
- Facility name — The node this entry is linked to
- GHG category — Which emissions category (e.g., purchased goods and services, electricity)
- Scope — Scope 1, 2, or 3
- Description — Always includes how the calculation was performed
- Supplier name — The vendor or provider
- AI confidence — For spend-based calculations, the confidence score of the AI classification
- Emissions — The calculated CO₂e value
- Emission factor — Which factor was applied
- Source file — Click to go directly to the uploaded file
You can customise which columns are displayed — NetNada has 22+ fields available, including activity, activity units, emission factor category, emission factor database, and more.
AI Confidence Scores
When spend-based calculations are used, NetNada assigns an AI confidence score to each entry. The scores are colour-coded:
| Level | Colour | Action |
|---|---|---|
| High (≥90%) | Green | Strong match — usually safe to proceed |
| Medium | Amber | Review recommended to ensure accuracy |
| Low | Red | Manual review required for compliance accuracy |
AI Search Filter
You don't need to know which scope or category to filter by. Type a natural-language question into the AI search bar and NetNada will set up the filters for you.
Examples:
- "Show me all electricity entries" — sets scope and category filters automatically
- "Entries without a supplier name" — filters for data quality gaps
- "Entries with no emission factor" — finds unmatched rows
- "Entries from CEDA database" — filters by emission factor source
Filtering
Beyond AI search, you can filter manually by:
- Entity / node — Select specific facilities (searchable dropdown)
- Time period — Filter by date range
- Scope — Scope 1, 2, or 3
- GHG category — Specific emissions categories
- Data source — File, invoice/bill, calculator, or modelling
- AI confidence — Filter by confidence level
- Supplier — Search by supplier name
- Data quality — Missing supplier name, missing emission factor, failed entries
- Emission factor source — Filter by database (e.g., CEDA, DEFRA, custom)
Editing Entries
Edit GHG Category
If a transaction was classified into the wrong category, you can reassign it. Select the entry, choose the correct GHG category, and provide a reason for the change.
Edit Emission Factor
Search for a different emission factor within NetNada's database by selecting the sector, category, region, source, year, unit type, scope, and lifecycle activity. NetNada pre-filters based on the entry's existing unit to show relevant options.
Bulk Editing
Apply a filter first to narrow your view, then use Select All to select all entries matching that filter. The selection count reflects only the filtered entries — for example, filtering for Scope 2 and selecting all might give you 24 entries. You can then apply changes (like a new emission factor) to all selected entries at once.
