Moving goods by sea is far 'greener' than any other major transportation method.

On average, for every kilometre that a container ship carries a ton of cargo, it is estimated that it emits around 40 times less CO2 than a large freight aircraft and over three times less than a heavy truck.

And container shipping is reckoned to be two and a half times more fuel-efficient than rail, and seven times more so than road.


Kuehne + Nagel has adopted the KNGreen initiative and joined 23 ocean carriers and 14 shippers as a member of the "Clean Cargo Working Group" (CCWG). The CCWG carrier members are measuring the actual consumption of bunker fuel and applying a common methodology for calculating and providing their individual trade lane-based CO2 emissions per gram/TEU/km. With numerous theoretical formulas and no globally accepted standard available at this time, the facts and figures delivered by members of the CCWG are the most realistic and credible available.

Kuehne + Nagel has included the CCWG methodology and emission factors in its carbon calculator and customer emission reports, enabling shippers to obtain reliable information regarding their seafreight supply chain's carbon footprint. The ultimate objective is for Kuehne + Nagel to assist customers in developing an environmentally-friendly supply chain model. This would optimise the routing, carrier and vessel selections and reduce the carbon footprint caused by redundant inland movements for the positioning and re-positioning of equipment.
