How Much CO2?
The following question was raised by a superyacht owner at a Boat International Explorer Yacht Summit at The Monaco Yacht Club.
"Can anyone tell me the CO2 emissions from my yacht use?"
What was striking that many industry professionals didn’t know either!
"After all, if we do not know the size of the problem, how can we possibly change it?"
There are a multitude of emissions in a full life cycle analysis (LCA) including those from equipment, materials and production. However, the CO2 from the fuel burnt and electricity consumed in the operational cycle, are by far the most significant and not hard to calculate.
If you are concerned, or just curious about your charter, yacht, or fleet CO2 emissions, simply enter your data into the calculators below:
- CO2 Emissions by Consumption
- CO2 Emissions by ME and Genest Power

Calculate carbon emissions from fuel consumption and shore power, then see how they compare to everyday equivalents.
CO₂ Emissions by Consumption
- IMO Tank-to-Wake Factor: 3.206 tCO₂ per tonne MGO/MDO.
- Carbon intensity of Caribbean shore power not included; Cyprus may serve as a useful proxy for island grids.
- Cars based on EU average passenger car — 118 gCO₂/km × 12,000 km/yr.
CO₂ Emissions by ME & Genset Power
- Main engines: SFC 190 g/kWh. Generators: SFC 210 g/kWh.
- IMO Tank-to-Wake Factor: 3.206 tCO₂ per tonne MGO/MDO. Fuel density: 0.84 kg/L.
- Underway: main engines + generators running. At anchor: generators only.
