Several major carriers now offer a carbon-neutral or low-carbon shipping option, typically structured either as a book-and-claim system (paying a premium that funds sustainable fuel use elsewhere in the carrier's network, without your specific cargo physically moving on a low-carbon vessel) or, less commonly, genuine low-carbon fuel allocation to a specific sailing.
The distinction matters for anyone intending to cite the purchase in their own sustainability reporting: a book-and-claim offset supports the broader transition to cleaner marine fuel but does not mean your specific shipment's actual emissions were reduced, which is a nuance that differs from how carbon offsets work in some other industries and is worth understanding before making a claim based on the purchase.
Pricing for these programs is generally a premium on top of standard freight, scaled to the shipment's estimated emissions, and currently a minority of shippers use them — uptake has grown steadily but remains a specialist choice rather than a standard default, partly because most shippers do not yet face a reporting requirement that specifically rewards the purchase.
We can arrange carrier-offered low-carbon options where a client specifically wants them and the carrier on that routing offers one; the environmental accounting methodology behind any specific program is the carrier's own, and worth reviewing directly against your own reporting standard before relying on it.
