Hong Kong's Pacific Basin Shipping has launched a scheme to allow charterers to offset their carbon emissions from its bulkers.
The carbon-neutral voyage programme offers "green" contracts of affreightment on a voluntary basis.
Chief executive Martin Fruergaard said: "Major commodity producers, traders and end users — including some of our customers — have expressed increasing interest in mitigating their environmental footprint, including by beginning to offset some of their currently unavoidable direct and indirect emissions."
