Fleet Fuel Use and Emissions Calculator
Estimate total fuel from distance and consumption rate, then apply a factor supplied for the chosen fuel.
How to use this calculator
- Enter distance, fuel use per 100 km and a defensible emissions factor from the source you select.
- Check that every input uses the stated units and covers the same period, population or project scope.
- Change one assumption at a time when comparing scenarios.
Formula used by fleet fuel emissions calculator
Fuel = distance × consumption ÷ 100; emissions = fuel × factor
- Fuel = distance × consumption ÷ 100; emissions = fuel × factor
- The factor must match the fuel and accounting method. It excludes upstream fuel supply and vehicle manufacture unless included in that factor.
- Inputs are validated against the tool-specific constraints; displayed results are rounded for readability.
Worked examples
Worked example
A 1,200 km trip at 7.2 L/100 km uses 86.4 litres; emissions depend on the entered kg CO₂ per litre factor.
The calculator shows estimated litres, kilograms and tonnes of CO₂.
The calculator shows estimated litres, kilograms and tonnes of CO₂.
Understanding the result
Estimate total fuel from distance and consumption rate, then apply a factor supplied for the chosen fuel.
The factor must match the fuel and accounting method. It excludes upstream fuel supply and vehicle manufacture unless included in that factor.
Important notes
The factor must match the fuel and accounting method. It excludes upstream fuel supply and vehicle manufacture unless included in that factor.
Treat the result as an estimate for the assumptions entered; verify important specifications against the relevant source or professional guidance.
Frequently asked questions
Is the default factor universal?
No. It is illustrative only; use an appropriate current factor for your fuel and location.
Does this include lifecycle emissions?
Only if the factor you enter includes lifecycle emissions; the label assumes a tailpipe-style factor.
How should I use this result?
Enter distance, fuel use per 100 km and a defensible emissions factor from the source you select.
