Your customer's sustainability form, answered from your own bills.
When a major customer asks you to report your environmental impact, SupplierESG helps you answer the whole questionnaire — calculating your carbon emissions directly from your utility bills and fuel receipts, showing the exact arithmetic behind every figure and stamping each one an estimate, while anything the bills can't answer is left blank, not guessed.
For suppliers & their advisors
Interactive walkthrough — sample questionnaire
The conversion rates used here are sample values for this demo. Real reporting must use the current official published rates (Australia's National Greenhouse Accounts Factors) — which is a big part of why every figure carries the estimate stamp.
What it read. Thirty-three bills and statements. One line — the forklift gas — is amber because three months of it had to be estimated from how often gas was delivered, rather than read straight off a bill. When the evidence is weaker, SupplierESG says so.
What it is
Big customers now ask their suppliers to prove they’re green.
To keep their own environmental promises, large companies increasingly require the smaller businesses they buy from to report their emissions and sustainability practices. If you supply one of them, that request lands on you — usually as a questionnaire with a deadline.
Your bills already hold most of the answer.
Calculating your carbon footprint normally means hiring a consultant. But the raw numbers are already in your electricity, gas and fuel bills — how much energy you used converts into an emissions figure using published conversion rates. SupplierESG does that calculation and shows its working.
Every number is marked an estimate — on purpose.
A figure calculated from utility bills is an estimate, not a formal carbon audit. SupplierESG stamps every figure “estimate” and locks the stamp in place. Presenting an unverified calculation as a hard measurement is a real compliance risk — marking it as an estimate is what protects your business.
How to use

The stamp travels with the numbers. It is on the panel, on every calculated answer, on the export, and approval does not remove it — approval records that a person accepted an estimate, not that the estimate became a measurement.
Sample supplier, sample bills — nothing here is sent anywhere. Open the full tool to drive it yourself, full size.
Before / After
Same fourteen questions, two ways to answer them.
Why every number says “estimate”.
Before — filled in by hand
Whatever numbers seem right.
One spreadsheet, one deadline, no arithmetic shown — a tonnage that reads as a measurement in the funder's portal whether or not anyone meant it to.
After — SupplierESG
Ten answered, four sent back honest.
Every figure carries its arithmetic and the ESTIMATE stamp. The four blanks are the ones a person still has to decide — not a gap the tool tried to hide.
The stamp is the product.
A small business can produce a rough emissions number from its own bills in an afternoon. What it can't do is turn that into an audited, assured figure — and the gap between the two is where suppliers get into trouble. A tonnage sitting in a customer's portal reads as a hard measurement, not an estimate, unless you clearly say so. So SupplierESG says so, on every figure, and won't let the stamp come off.
Remove the estimate stamp
Not on sign-off, export, or PDF.
Infer your energy source mix
Usage confirms volume, not where it was generated.
Fabricate a policy or certification
Guess your full supply-chain emissions (“Scope 3”)
Reporting Scope 3 as unmeasured is defensible; an invented figure is a compliance risk.
Four blanks, on purpose
The fourteen questions, minus the ten SupplierESG answers, leaves four.
All four go back as blanks with the reason attached — because a blank with a reason is an honest answer, and a made-up one is a compliance risk.
The panel above shows three figures — electricity emissions read from invoices, fuel-card diesel and petrol, and an LPG estimate built from delivery frequency — each one tied back to the bill or docket it came from.
