The CO2 calculator below compares the options of operating a tanker with a 'return haul' (column left) and without a 'return haul' (column right.)

The numbers in the blocks can be replaced with your operational data, to calculate diesel consumption CO2 produced annually in your fleet.

One litre of diesel contains 0,72 kg of carbon which requires 1,92 kg of oxygen to burn - producing 2,64 kg of carbon dioxide.
