IN Brief:
- cargo-partner reports an 811-tonne CO₂e reduction through sustainable marine fuel during H1 2026.
- Hapag-Lloyd allocated 259.46 tonnes of waste- and residue-based biofuel through its Ship Green programme.
- The emissions reduction was calculated well-to-wake using a methodology subject to independent assurance.
cargo-partner says its use of sustainable marine fuel through Hapag-Lloyd’s Ship Green programme reduced ocean freight emissions by 811 tonnes of CO₂e during the first half of 2026. The freight forwarder attributes the result to 259.46 tonnes of waste- and residue-based biofuel allocated within Hapag-Lloyd’s fleet, with the reduction calculated on a well-to-wake basis against conventional fossil marine fuel.
The reported total comprises 290.58 tonnes of CO₂e avoided during the first quarter and 520.42 tonnes during the second. cargo-partner says the fuel came from certified sustainable supply chains compliant with the EU Renewable Energy Directive II, while the accounting process follows Hapag-Lloyd’s Ship Green Process Report 2025 and has undergone limited independent assurance under ISAE 3000.
Ship Green uses an allocation model rather than requiring the alternative fuel to be burned on the exact vessel carrying each participating customer’s container. Hapag-Lloyd introduces qualifying fuel into its fleet and assigns the corresponding emissions reduction to eligible freight volumes, enabling cargo owners to purchase a documented reduction without constructing a dedicated fuel supply chain for each route.
That approach is useful because alternative marine fuel is not available in equal quantities at every port. Shipping networks span hundreds of services and bunkering locations, while certified low-carbon fuel supply remains concentrated in a relatively small number of markets. Allocation allows the physical fuel to be used where it can be sourced while the environmental benefit is assigned through an accounting mechanism.
The credibility of that model depends heavily on measurement. A customer receiving an emissions claim needs confidence that the allocated fuel was actually used, that the reduction has been calculated against an appropriate fossil baseline, and that the same benefit has not been sold more than once. Independent assurance and documented chain-of-custody processes therefore carry more weight than the branding attached to the product.
cargo-partner’s figures are based on well-to-wake emissions, which account for greenhouse gases associated with producing and supplying the fuel as well as its use aboard the vessel. That is more demanding than considering combustion alone because different alternative fuels can have very different upstream emissions depending on feedstock and production route.
The programme uses biofuel produced from waste and residue materials. Such feedstocks avoid some of the land-use concerns associated with crop-based fuels, although availability remains limited and demand extends beyond shipping into sectors including aviation and road transport. Scarcity and price therefore remain constraints even where the emissions methodology is robust.
For freight procurement, the main advantage is that an insetting product can be added to existing ocean shipments without requiring the customer to redesign its physical transport network. A shipper can retain the same carrier service and routing while paying for qualifying alternative fuel to enter the carrier’s fleet elsewhere. That makes the mechanism easier to incorporate into tenders and annual freight allocations than a bespoke physical fuel arrangement for every trade lane.
The same simplicity makes accurate reporting more important. Scope 3 transport emissions are increasingly being measured at shipment or lane level, and companies using purchased reductions in environmental reporting need records that can withstand internal or external scrutiny. cargo-partner says its SPOT platform provides shipment-level greenhouse gas information alongside options for lower-emission transport.
The 811-tonne reduction remains small beside the emissions produced by global container shipping, but the comparison is of limited use for an individual freight buyer. Procurement teams control their own contracted volumes rather than the world fleet, so the practical measure is whether verified lower-emission options can be applied repeatedly across a meaningful share of the traffic they purchase.
Scale will ultimately depend on fuel supply. Book-and-claim and allocation systems can distribute the environmental benefit of scarce fuel more efficiently, but they do not manufacture additional biofuel or remove the premium over conventional bunker fuel. Greater uptake still requires more qualifying fuel to enter the market alongside sufficiently strict rules over feedstock, lifecycle emissions, and allocation.
cargo-partner’s first-half result at least provides a measured operational figure rather than another distant decarbonisation target. The next question is whether the tonnage of alternative fuel allocated through programmes such as Ship Green continues to increase without weakening the audit trail behind the claims. In freight emissions reporting, an impressive percentage is easy enough to print; proving exactly where the reduction came from is the more valuable service.
