Emission Factor Control
By default, NetNada AI finds and applies the most appropriate emission factor for every transaction — and the confidence of each selection is visible in the audit table. But when you need more control, you can override any factor by browsing our global database of emission factors, narrow your search with smart filters for unit type, category, and region, and apply the exact factor you need — all without ever leaving your workflow.
How It Works
Emission Factor Control gives you transparency and authority over how your emissions are calculated. NetNada's AI handles the heavy lifting by default, but you can step in at any time to review, override, or fine-tune the emission factors applied to your data.
AI Selects the Best Match Automatically
When you upload transaction data, NetNada AI analyses each line item and applies the most appropriate emission factor from our global database. The AI considers the transaction description, amount, currency, supplier category, and region to find the best match — so most of the time, you don't need to do anything.
Review Confidence in the Audit Table
Every AI-selected emission factor comes with a confidence score visible in the audit table. High confidence means the AI is certain about the match. Lower confidence flags transactions where the factor selection may need your review — giving you a clear prioritisation of where to focus your attention.
Browse the Global Emission Factor Database
When you want to override a selection, open the emission factor browser directly from the audit table. Search across our global database powered by Climatiq, covering thousands of factors from sources including EXIOBASE, CEDA, DEFRA, EPA, and Australian NGA Factors. Use keyword search to find exactly what you need.
Narrow Down with Smart Filters
Use smart filters to refine your search by sector, category, region, source dataset, year, unit type, scope, and lifecycle activity. The filters work together to help you find the precise factor for your situation — whether you need a spend-based factor in AUD for Australian manufacturing or a physical unit factor in kWh for European electricity.
Apply with Smart Compatibility Checking
Before you apply a new factor, NetNada automatically checks that it is compatible with your transaction data. If you are modifying a dollar-denominated transaction, the system ensures you select a monetary emission factor and prevents you from accidentally applying a physical unit factor like kg/L. Select the factor, provide a reason for the change, and save — the audit trail captures everything.
Why Use Emission Factor Control
AI Does the Heavy Lifting
NetNada AI automatically selects the most appropriate emission factor for every transaction. For the majority of your data, the AI gets it right — saving you hours of manual factor matching. You only need to step in when you want to refine or override a selection.
Full Transparency Through Confidence Scoring
Every emission factor selection comes with a confidence score visible in the audit table. You can see exactly which factor was applied, why it was chosen, and how confident the AI is in the match. No black boxes — complete transparency over your carbon calculations.
Global Database at Your Fingertips
Browse thousands of emission factors from leading international databases including EXIOBASE, CEDA, DEFRA, EPA, and Australian NGA Factors. Whether you need a region-specific factor, a particular dataset vintage, or an industry-specific coefficient, it is all searchable in one place.
In-App Selection Without Breaking Your Workflow
Find and apply the exact emission factor you need without leaving the audit screen. The emission factor browser opens as an overlay, letting you search, filter, and select a factor in seconds — then you are straight back to reviewing your data.
Smart Compatibility Prevents Errors
NetNada automatically checks that the emission factor you select matches the data you are modifying. If you are looking at a dollar-denominated transaction, the app knows you need a monetary EF and prevents you from accidentally applying a physical unit factor. Fewer errors, more confidence.
Complete Audit Trail for Every Change
Every emission factor override is logged with who made the change, when, the reason provided, and the previous factor. This gives auditors and assurance providers full traceability over your emission factor selections — critical for mandatory reporting and external assurance.
Who Uses Emission Factor Control
Sustainability Managers Seeking Precision
When the AI-selected factor is close but not quite right, sustainability managers can browse the database and apply a more precise factor. Perfect for industry-specific activities where a generic factor does not capture the nuance of your operations.
Carbon Accountants Preparing for Assurance
External assurance requires defensible emission factor choices. Carbon accountants use Emission Factor Control to review AI selections, verify appropriateness, and document override reasons — building the audit trail that assurance providers expect.
Organisations with Sector-Specific Requirements
Some industries have preferred or mandated emission factors. Emission Factor Control lets you apply the exact factors required by your industry body, regulator, or certification scheme — overriding generic factors with sector-specific ones.
Consultants Managing Multiple Clients
Sustainability consultants working across different industries and regions use the smart filters to quickly find region-specific and sector-specific factors for each client. The in-app workflow means they can review and adjust factors across client portfolios efficiently.
Teams Transitioning from Spend-Based to Activity-Based
As organisations improve data quality, they often need to switch individual transactions from spend-based to activity-based emission factors. Emission Factor Control makes this transition seamless — override the spend-based factor with an activity-based one as better data becomes available.
Emission Factor Control Features
AI-Powered Automatic Selection
NetNada AI analyses each transaction and applies the most appropriate emission factor from our global database. The AI considers transaction description, amount, currency, supplier category, and region to find the best match automatically.
Confidence Scoring in Audit Table
Every AI-selected emission factor displays a confidence score in the audit table. High confidence indicates a strong match, while lower scores flag transactions that may benefit from manual review and override.
Global Emission Factor Browser
Search across thousands of emission factors from EXIOBASE, CEDA, DEFRA, EPA, Australian NGA Factors, and other leading databases. Keyword search and pagination make it easy to find the exact factor you need.
Smart Filters
Refine your search with filters for sector, category, region, source dataset, year valid, unit type, scope, and lifecycle activity. Combine multiple filters to narrow results from thousands to the handful that match your specific requirements.
Unit Compatibility Checking
Automatic validation ensures the emission factor you select is compatible with your transaction data. Dollar-denominated transactions require monetary emission factors; physical quantity data requires physical unit factors. Mismatches are blocked before they cause calculation errors.
In-App Override Workflow
Override any emission factor directly from the audit table without leaving your workflow. The emission factor browser opens as a modal overlay — search, filter, select, provide a reason, and save in seconds.
Change Reason Documentation
Every override requires a reason for the change, captured alongside the new factor selection. This documentation supports internal governance and provides assurance providers with the justification behind every factor choice.
Full Audit Trail
Complete history of every emission factor change — who made it, when, the previous factor, the new factor, and the stated reason. The audit trail is available for export and review by assurance providers.
