About $3.3M of fuel identified across 91 replayed Atlantic crossings. 90 of them came out ahead, with savings of 2.7% to 32.8% per voyage. Blueroutes by Greensee prices the fuel that keeps reefer cargo cold, and delivers the route through ABB Ability™ Vessel Routing, the engine many bridges already run.

Greensee × ABB — September 2026 · Reefer vessel routing & fuel savings

What we replayed

Two fleets, two very different trades, one method. Every voyage was replayed against the vessel’s actual sailed track from AIS, held to the same schedule, and compared on total ship fuel. Nothing was surveyed, modelled from averages or taken from a vendor brochure. The numbers below are what the ships would have burned had they followed the recommended route instead of the one they sailed.

• 29 crossings, six reefer container vessels, Europe–South America, H1 2026. The original Blueroutes validation: reefer-heavy ships where cargo cooling is a large share of the fuel bill.
• 62 crossings, North Atlantic, 2026. A second operator’s voyages, where severe weather forces captains to choose between sailing south of the storms and holding a direct track.

The results

2.7–32.8%

~$3.3M

Sail south or sail short, the saving is still there

Every North Atlantic crossing starts with the same decision. Some captains add distance to route around the storm systems, trading fuel for safety. Others hold the direct track and accept the weather penalty. A routing engine that only “wins” by overruling that decision is not one a fleet manager can trust.

So the 62-voyage replay was constrained. Where the captain sailed south, a mandatory waypoint near the Azores forced every alternative route through the same southern corridor. What was measured is optimisation within the captain’s own strategy, not credit for a north–south call the captain never considered.

The saving held up on both sides. Longer, weather-avoidance voyages averaged 8.1% less fuel. Shorter, direct voyages averaged 11.8%. At the extremes, an already-short 4,702 km voyage still gave up

Blueroutes by Greensee, delivered through ABB Ability™ Vessel Routing, replayed on real AIS tracks across two Atlantic fleets.

→ 2.7% to 32.8% less fuel per voyage → 10% average saving on 62 North Atlantic crossings → Saves on the captain's own route, sail south or sail short → Via API. No hardware, one waypoint a day.

Very proud to have CMA, PIL and Thermoking partner with Seacube and Greensee in the Green Reefer Lease innitiative

SeaCube, a global leader in refrigerated intermodal equipment leasing, has partnered with Greensee to launch innovative solutions that redefine sustainability in the refrigerated transport sector. This collaboration introduces SeaCube's Green and Net-Zero Reefer Leases, powered by Greensee's AI-driven CO2 emissions reporting technology, setting a new standard for energy efficiency and environmental responsibility in cold chain logistics.

Intermodal shipping has been planned based on cost and ETA; but the world's changing and new dynamics come into play : GHG emissions (CII, ETS), route disruption (Suez, Panama) need to be integrated into shipping planing and sourcing.
How ?

And plan your Zero Emission strategy with actual data.

Calculating distance over road is simple;

Over rail or waterway is not that easy. But this is needed to estimated transport CO2 emissions.

Bluepulse has announced a distance calculation tool which works worldwide for rail, barge and road transport !

You can test, selecting any origin and destination;

Service available via API, compliant with ISO 14083 standard

you can see container emission data on few samples , and potential savings :

Greensee, a new solution will be announced at Intermodal, Amsterdam, on Oct 10th. Don Miller is heading Greensee which offers CO2 tracking solutions and CO2 savings scenario to the intermodal industry : 

- Greensee tracks container emissions, from booking data or IoT data

- Greensee offers CO2 reduction scenarios and insights to freight forwarders and shipping lines.

- Greensee runs your CO2 tracking and accounting back end as plug and play and connects via API
