Tender & Supplier Carbon Data
Scope 3 Supplier Emissions Data Response Support
A customer sent you a carbon questionnaire, and you need a defensible response. Aethiro interprets the request, prepares the required calculations and puts the answer into a format your customer can review.

Answer the request you actually received
Mining companies, supermarkets and industrial buyers can ask for different boundaries, periods and evidence. We start with their questions, not a standard report that may miss the requirement. Support is available across Queensland and Australia, including small businesses responding for the first time.
Do suppliers need to calculate all 15 Scope 3 categories?
No. For a customer’s purchased goods and services inventory, supplier-specific data usually means the cradle-to-gate emissions of the goods or services supplied. This is a product or service boundary, not simply your organisation-wide Scope 1 and Scope 2 totals. The calculation method, allocation basis, reporting period and evidence must follow the customer’s request. Use the Carbon Question Decoder for an initial explanation of unclear wording.
A response with a traceable basis
Required calculations
Emissions calculations matched to the request, using relevant business records and documented methods.
Response tables
Figures and explanations prepared in the requested questionnaire or response format, within the agreed scope.
Supporting methodology
A record of sources, assumptions, exclusions and data gaps so limitations remain visible when the response is shared.

How the response comes together
Review the questions
Share a redacted request and deadline. We confirm the deliverables, fee, records needed and any clarification for the buyer.
Prepare and check
We calculate the agreed figures, identify evidence gaps and review the draft response with you.
Approve and return
You approve the response before sending it to the customer. Follow-up questions outside the agreed scope are assessed separately.
Start with the request and existing records
Useful inputs include the questionnaire, requested reporting period, sites and entities, fuel and electricity records, and any previous carbon inventory. Spend, freight or other records may be needed if the customer asks for additional emissions information.
Set clear expectations
Will the customer accept the response?
Acceptance remains the customer’s decision. We document the basis and limitations, and flag requirements that need more work or clarification. A questionnaire response is not independent assurance.
What if the request becomes broader?
A complete inventory may need Carbon Footprint Analysis. If the buyer asks what you will change, Emission Reduction Planning addresses actions separately.

Start with the customer’s questions
Include the deadline and a redacted copy of the request. We will confirm whether the work fits before proposing a scope.
