Drop your bills. Get Scope 1 and 2 back.
Electricity, gas and fuel bills in one spreadsheet. Every row is checked before anything is calculated, and every number shows where it came from. Free, no sign-up.
- Calculated by the GHG engine, not by AI
- Published factors: DEFRA 2025 for fuels, the IEA grid factor of your country
- Every line traced: amount × factor = tonnes
Nothing is calculated until you confirm what was read.
How it works
- 01Bring your billsOne row per bill: site, month, energy, quantity and unit. Use the sample to see the layout.
- 02Every row is checkedEach row is read and checked before anything is calculated. You see what can’t be used, and why.
- 03The engine calculatesThe same deterministic GHG engine as the app, with published factors. The same rows always give the same answer.
- 04Take the workbookInputs, factors and results with live formulas, plus the gaps a verifier would ask about first.
Every number, traced
Click any line of your results to see the amount from your file, the factor with its source and version, and the tonnes they make. Nothing to rebuild when a consultant or a verifier asks.
