Fuel CO₂ calculator
Enter the mass of fuel consumed to estimate CO₂ emissions.
Fuel consumed
Enter consumption for the same period in metric tonnes (t = 1,000 kg). Leave unused fuels at zero. Do not enter bunker deliveries, remaining stock or litres.
Results
Enter consumption, then calculate.
Total CO₂ emissions
t CO₂
Total fuel consumed: t
| Fuel | t | t CO₂ |
|---|---|---|
| HFO · Heavy fuel oil | ||
| LFO · Light fuel oil | ||
| Diesel / Gas oil |
For reference; does not replace a verified emissions report or establish regulatory compliance. Confirm fuel classification and the applicable reporting method.
Calculation
CO₂ (t) = Σ [fuel consumed (t) × fuel conversion factor]. Displayed values round to three decimal places; totals use unrounded values.
Estimates combustion CO₂ for three fossil oils. Excludes biofuel blends, alternative fuels, CH₄, N₂O and upstream emissions. This is not CO₂e, lifecycle emissions or an ETS cost calculation.
