An emissions reduction project launched by Denmark-headquartered Christiania Shipping with behaviour change service Signol earlier this year has saved more than 250 metric tonnes (mt) of fuel in six months, avoiding at least 790 mt of CO2, according to Signol on Tuesday (10 December). 

The success was achieved across Christiania’s original 18-vessel fleet, which has recently expanded, and amounted to a cost saving of more than USD 150,000 from the shipping company’s fuel bill and USD 48,000 from regulatory costs under the EU Emissions Trading System (EU ETS).

Since March 2024, Signol’s solution has enhanced Christiania’s fuel efficiency initiatives by using fuel performance data alongside behavioural science to identify opportunities to save fuel and help crew members increase their fuel-saving actions.

Christiania has now converted the partnership with Signol into a long-term contract to continue engaging crew members on fuel efficiency and achieving further emissions reductions.

Rune Eriksen Lorentsen, Christiania’s Director Operations and Performance, said: “Our six-month trial with Signol almost immediately showed the value of effectively engaging with our crew on fuel efficiency.

“Not only did the resulting fuel reductions produce significant cost-savings, leading to a remarkably quick return on investment, but Signol also helped generate real buy-in from our crew on operational efficiency and decarbonisation, which has created a culture of positive engagement onboard.”

A significant proportion of Christiania’s impressive savings were due to the impact Signol had by helping the crew take more opportunities to optimise vessel trim.

Crew members showed a 16% increase in successful implementation of the trim behaviours during the trial period, with vessels systematically trimmed an average of 0.22 metres closer to even keel, which almost always represents the most efficient trim for the vessel type.

“Our ongoing work with Christiania Shipping shows that focusing on efficient human behaviour can close the gap between fuel performance monitoring and achieving tangible improvements to reduce emissions in practice,” said Harriet Hunnisett Johnson, Head of Maritime at Signol.

“Christiania has very quickly seen that small changes to crews’ actions can add up to really significant fuel savings. The collaboration between Signol and Christiania created a culture of positive engagement with sustainability onboard and the conditions for crew members to do their best work and know that they are making a difference.”

Signol’s behavioural science solution took Christiania’s existing fuel performance monitoring initiatives a step further by using detailed vessel data and insights on fuel consumption to identify four specific opportunities for fuel saving and promote related fuel-saving actions across 70 crew members.

Alongside Signol’s set of behaviour change techniques, Christiania also added Signol’s optional techniques of charitable and personal incentives, making donations to two causes for every fuel-saving goal hit: ships’ welfare funds and The Ocean Cleanup charity.

During the trial, Christiania’s crew hit 4,400 fuel-saving goals.

World Fuel and partners complete first green methanol bunkering of car carrier in Shanghai

Marine fuel provider World Fuel on Tuesday (21 July) said it successfully completed the first green methanol bunkering of M/V Arctic Tern, with EUKOR Car Carriers and SIPG Energy at the Port of Shanghai. 

Arctic Tern is the first vessel in the new Shaper Class series of car carriers. 

The operation involved the delivery of approximately 2,800 MT of green methanol to Arctic Tern via a ship-to-ship transfer using SIPG Energy’s dedicated methanol bunkering vessel M/V Hai Gang Zhi Yuan, the largest vessel of its kind in operation. 

The bunkering operation was carried out at Haitong Terminal, Waigaoqiao Port Area, Shanghai Port, with cargo handling operations conducted simultaneously during bunkering.

This marks EUKOR Car Carriers’ first green methanol operation and the first time Arctic Tern has bunkered methanol since its delivery on 9 July. The operation marked the first bunkering at Shanghai Port of green methanol produced locally in Shanghai for an international PCTC operator. 

It also demonstrated the city’s integrated green methanol value chain, spanning local production, storage and bunkering, and established a replicable “Shanghai Model” for green methanol supply.

World Fuel arranged the supply and delivery of the fuel on behalf of EUKOR Car Carriers, working with SIPG Energy as the physical supplier at the Port of Shanghai.

The green methanol supplied was produced from municipal solid waste, ISCC-EU certified, and had a carbon intensity value below 25 gCO₂e/MJ.

Arctic Tern is the first of fourteen Shaper Class vessels ordered by Wallenius Wilhelmsen. With a capacity of 9,300 car equivalent units and methanol dual-fuel capability, the vessel will be operated by EUKOR Car Carriers, jointly owned by Wallenius Wilhelmsen and Hyundai Motor Group. Following her first green methanol bunkering, Arctic Tern will continue her maiden voyage from Asia to Europe.

Xavier Leroi, COO Shipping Services at Wallenius Wilhelmsen and CEO of EUKOR Car Carriers, said: “Completing Arctic Tern’s first green methanol bunkering shortly after delivery is a significant milestone towards our decarbonisation ambition for both EUKOR Car Carriers and Wallenius Wilhelmsen. It demonstrates how investments in next-generation vessel technology and fuel flexibility are being translated into real-world operations. 

“This achievement reflects the strong collaboration between all parties involved. Together, we have shown how partnerships across the maritime value chain can help make lower-emission fuels available and operationally viable at scale.”

Mark Tamsitt, SVP Global Marine Sales at World Fuel, said, “The first bunkering event with a new fuel is a significant moment for any shipowner, and our role is to make it as seamless as possible. By connecting EUKOR Car Carriers with SIPG Energy’s proven green methanol capability at the Port of Shanghai, we were able to deliver on reliable supply, fuel quality, and safe processes. As more of our customers bring methanol dual-fuel tonnage into service, we are committed to being the partner that makes these kinds of operations routine.”

Mr. Zhang Da, General Manager of SIPG Energy, said, “Welcoming Arctic Tern to the Port of Shanghai for her first green methanol bunkering demonstrates the strength and maturity of our supply capability. Building on our well-established methanol ship-to-ship bunkering services for container vessels, we have already extended such services to pure car and truck carriers (PCTCs). This bunkering sets a new record for the largest single SIMOPs green methanol bunkering for PCTCs in China, marking another step in building Shanghai’s position as a global green energy hub for international shipping.”

This operation follows Wallenius Wilhelmsen’s announcement on 9 July that Arctic Tern would complete her first methanol bunkering shortly after delivery. The vessel entered service on routes between Asia and Europe immediately following handover from China Merchants Jinling Shipyard in Nanjing.

HPA and MB Energy develop safety concept for STS ammonia bunkering

The Hamburg Port Authority (HPA) and integrated energy company MB Energy on Tuesday (21 July) said they have completed a comprehensive risk analysis and developed a dedicated safety concept for ship-to-ship ammonia bunkering.

MB Energy said the analysis lays the groundwork for the safe introduction of ammonia as a future marine fuel.

“With our planned ammonia import terminal in Hamburg-Blumensand, MB Energy intends to provide the reliable land side supply infrastructure needed to support this transition across northern German ports,” it said in a social media post. 

Mabanaft Group was renamed to MB Energy last year and merged over 50 existing brands under one identity. 

Separately, HPA said the Port of Hamburg will become “bunker ready” for ammonia, laying the groundwork for safe and reliable ammonia bunkering in the future.

“The focus is in particular on container ships, cruise ships as well as RoRo and ConRo (Container/RoRo) ships,” it said. 

“We expect ammonia to establish itself as an alternative marine marine fuel in the coming years. With our preparatory work, we are already creating the conditions to welcome the first ammonia-powered ships in Hamburg and to bunker them safely.:

HPA added that the import terminal for ammonia planned by MB Energy from 2029 will make a decisive contribution to ensuring the reliable availability of ammonia as a bunker fuel in northern German ports in the long term. 

“The use of an ammonia bunker barge is considered a possible addition to the landside infrastructure to enable ship bunkering in the port and beyond in the future,” it said.

Alkagesta highlights key insights of Malta bunkering market in 2026

In an article published on Alkagesta Market Insights, Darren Lee Axisa, Malta Country Manager of Alkagesta, on Monday (20 July) discussed the key trends influencing Malta’s bunkering market and the factors that will determine Malta’s long-term competitiveness as a regional bunkering hub: 

Malta’s bunkering and energy market is moving through a period of structural adjustment. The disruptions that defined the first half of 2026 have accelerated shifts in product demand, terminal strategy, and the competitive dynamics of one of the Mediterranean’s most strategically positioned bunkering hubs. For Alkagesta, whose storage footprint on the island approaches 300,000 cubic metres, the period has tested operational flexibility while reinforcing the value of diversified infrastructure access.

A Market Shifting in Two Directions

Malta’s broader economy has remained resilient — GDP growth reached 3.9% in Q1 2026 — but the bunkering market has undergone a significant product mix shift, the roots of which predate the current geopolitical disruption.

The Mediterranean Emission Control Area, which came into force on 1 May 2025, triggered an immediate and measurable realignment in fuel demand across the region. VPS data covering the first six months post-ECA implementation shows that across the top ten Mediterranean bunkering ports, VLSFO volumes fell 23%, MGO more than doubled, ULSFO quadrupled, and biofuels increased fivefold. In Valletta specifically, the shift was even more pronounced: VLSFO dropped 57% from 111,641 mt to 47,732 mt, while MGO volumes more than tripled from 33,299 mt to 103,445 mt, and ULSFO rose from 2,821 mt to 34,535 mt over the same period.

This structural rotation has been further accelerated by the broader regulatory environment. FuelEU Maritime and EU ETS requirements are pushing shipowners toward cleaner, verifiable fuel options at every port call — a direction Alkagesta had already positioned itself ahead of, having been among the first movers in the Mediterranean to support the transition to 0.1% sulphur fuel oil following the ECA’s introduction.

Layered on top of this regulatory shift has been a period of reduced terminal capacity affecting bunkering market availability across the island. Fuel oil volumes dropped roughly 35% year-on-year between January and May 2026, falling from approximately 382,000 mt in 2025 to 247,000 mt. DMA demand moved sharply in the opposite direction, rising from around 150,000 mt in January to April 2025 to 247,000 mt over the same period in 2026 — a trend consistent with both the ECA-driven product mix shift and the disruption to heavier fuel availability during the constrained period.
