Carbon Footprint Calculator
A Quick CO2e Estimate for Any Fuel
Rather than working from ultimate analysis, this calculator applies a published emission factor directly to a fuel quantity, the fastest way to estimate carbon footprint when a standard factor is already available for your fuel type.
The Formula
Carbon Footprint (CO2e) = Fuel Quantity × Emission Factor
Common factors: natural gas ~2.0 kg CO2e/m3, diesel ~2.68 kg CO2e/L, gasoline ~2.31 kg CO2e/L.
Worked Example
500 liters of diesel at 2.68 kg CO2e/L:
Footprint = 500 × 2.68 = 1,340 kg CO2e
How to Use This Calculator
- Enter the Fuel Quantity consumed.
- Enter the appropriate Emission Factor for your fuel and unit.
- Select Calculate to get the carbon footprint in kg CO2e.
