Ocean Network Express launches CO2 emissions calculator

Ocean Network Express (ONE) has launched a calculation tool to count the carbon dioxide (CO2) emissions from its operating vessels.

With the ONE Eco Calculator, units are expressed as either Tank-to-Wake (TTW), a measure of emissions from burning fuel, which has been stored in a tank, or Well-to-Wake (WTW), a measure of emissions from fuel production, delivery, and use aboard ships.

Koshiro Wake, senior vice president of corporate strategy and sustainability department at ONE, said: “As we strive towards decarbonisation, ONE is on a continuous journey to encourage stakeholders to participate.
