Clean Arctic Alliance

The Clean Arctic Alliance’s Lead Advisor Sian Prior on Thursday (23 July) issued a response to a post by Francisco Malta of VM Industrials – Aderco Oceania, and a subsequent statement by the International Bunker Industry Association (IBIA) regarding black carbon emissions from very-low sulphur fuel oils (VLSFOs), and urged the industry to focus on reducing black carbon emissions in the Arctic by switching to distillate or cleaner fuels:

“It is vitally important that uncertainties of this kind do not delay urgently-needed action to reduce black carbon emissions from ships. We know that black carbon is a short-lived climate forcer – it is the strongest light-absorbing component of particulate matter, and is a critical contributor to human-induced climate heating, especially in the Arctic where the impact of black carbon emissions is magnified. We also know that black carbon has a negative impact on human health, including respiratory diseases and premature death [2]. Internationally, efforts are being made to reduce emissions of black carbon from all sources. In 2011 the United Nations Economic Commission for Europe (UNECE) urged the International Maritime Organization (IMO) to act on black carbon, while in 2013/14 the Climate and Clean Air Coalition (CCAC) renewed a call for action on black carbon emissions from the shipping sector. In 2017, the Arctic Council established a target of a 25-33% reduction in black carbon emissions below 2013 levels by 2025 for all sources.”

“Yet, black carbon emissions from shipping in the Arctic are rising. Between 2015 and 2019 there was a 73% increase in black carbon emissions from ships using heavy fuel oil (HFO) in the Arctic, according to soon-to-be published research from the International Council on Clean Transportation [3]. While IMO Member States have spent over a decade considering black carbon emissions from shipping, defining black carbon, deciding how best to measure black carbon, there has so far been no action agreed to reduce black carbon emissions from shipping.”

“It is clear that there is considerable uncertainty around the composition of the new VLSFOs, the relative importance of the paraffinic and aromatic content and the emissions that result from these new fuels. It is also clear from published work that there are many variables which have an impact on the efficiency of the “burn” of the fuel and affect black carbon emissions. There is a small amount of published work indicating that there could be higher black carbon emissions from VLSFOs, the new LinkedIn post suggesting in addition that new VLSFO fuels may emit higher black carbon emissions, and the fuel industry’s reassurances that “VLSFOs delivered to ships have so far generally been more paraffinic and less aromatic than the HSFOs they have replaced” [4,5]. Frustratingly however, there is a lack of publicly available, independently validated data from measurements of VLSFOs.”

“However, what is important now is the effort to significantly reduce black carbon emissions from shipping. This is possible with a rapid switch from HFO or VLSFOs to lighter, cleaner distillate fuels. A global switch to distillate would need to be phased in to ensure sufficient supply. However, a switch to distillate for ships operating in and near to the Arctic, where the impact of black carbon emissions is even greater, is feasible now and is urgently needed.”

“The Clean Arctic Alliance is calling for IMO Member States to require ship operators to switch from HFO or VLSFOs to distillate fuels or other cleaner alternative fuels, when operating in or near the Arctic. A switch from HFO to distillate fuels will reduce black carbon emissions by around one-third. This would then allow the installation of an efficient particulate filter (already required for road transport) which would reduce black carbon emissions by over 90%.”

A new consortium facilitated by the Global Maritime Forum and RMI will work to establish a green shipping corridor between the Port of Açu in Brazil and the Port of Antwerp-Bruges in Belgium, according to Global Maritime Forum on Thursday (4 June). 

In addition to the port teams on both ends of the corridor, the consortium includes HIF Global, Fuella, NYK Line, Höegh Autoliners, and Wallenius Wilhelmsen. 

The consortium will assess infrastructure, vessels, and business models to create a roadmap for transporting zero-carbon fuels produced in Açu, such as e-ammonia or e-methanol. The transport itself would also be powered by the same zero- or near-zero-emission fuels.

“We’re thrilled to be working with these partners to take these important steps towards Brazil’s e-fuel production and bunkering opportunity, whilst supporting the growing demand for e-fuels in Europe,” said Eleanor Wells, a senior project manager at the Global Maritime Forum.

The new consortium builds on a pre-feasibility study developed by RMI and the Global Maritime Forum in November 2025. 

The study highlighted the competitive projected costs of e-fuel produced in Açu, due to Brazilian policies supportive of green hydrogen production, the country’s largely renewable electricity grid, its abundance of renewable energy sources, and a relatively low cost of capital. A 2024 report from the same two organisations, Oceans of Opportunity, identified the Port of Açu as a high-potential e-fuel export hub.

Green shipping corridors are dedicated trade routes where the feasibility of zero-emission shipping is catalysed by public and private action. These routes are seen as central to delivering on the shipping industry’s goal of having zero-emission fuels account for 5% of all fuels by 2030. 

While green corridors have rapidly expanded in popularity worldwide, and a handful of initiatives have now reached the realisation stage, the most recent edition of the Annual Progress Report on Green Shipping Corridors warned that progress is being stalled by a ‘feasibility wall’ created by the cost gap between conventional and zero-emission fuels.

The Global Maritime Forum and RMI will continue to facilitate the realisation of the Açu-Antwerp green corridor, with work already moving at pace to progress beyond pre-feasibility and develop a feasibility analysis for the corridor. The feasibility analysis is expected to be published by the end of the year, with the consortium meeting regularly in the meantime.

StormGeo and OceanScore link emissions data, compliance workflows

Weather intelligence and decision support solutions provider StormGeo and Hamburg-based technology platform OceanScore on Wednesday (3 June) said they have deepened their ongoing cooperation through the signing of a collaboration agreement during Posidonia 2026 in Athens on 2 June.

The cooperation combines StormGeo’s expertise in operational vessel and emissions data with OceanScore’s expertise in emissions compliance workflows across EU ETS, FuelEU Maritime and upcoming UK ETS requirements.

Together, the companies aim to help shipping companies seamlessly navigate increasing regulatory complexity more efficiently — from emissions reporting and data validation to compliance exposure management, pooling and financial settlement.

As emissions regulation becomes an increasingly important part of commercial shipping operations, the need for reliable operational data and streamlined compliance processes continues to grow. The cooperation between StormGeo and OceanScore is designed to support shipping companies with more connected, transparent and actionable processes across operational and commercial teams.

“From the outside, companies like StormGeo and OceanScore may sometimes be perceived as competitors because both operate around emissions and compliance workflows,” said Albrecht Grell, Managing Director at OceanScore. 

“But in reality, the industry increasingly needs both perspectives working together: trusted operational emissions data on one side and commercial compliance execution on the other. Our cooperation reflects that shipping companies are no longer looking for isolated solutions — they need connected processes, automated across different systems and reliable decision-making throughout the full compliance chain.”

By connecting validated operational emissions data with commercial compliance management, the cooperation supports workflows across:

  • emissions reporting and validation 
  • compliance management across EU ETS, FuelEU Maritime and upcoming UK ETS requirements
  • exposure visibility and cost transparency
  • pooling, settlement and financial processes 

The cooperation also aims to improve commercial transparency and coordination across operational and commercial stakeholders.

“StormGeo plays a central role in helping shipping companies turn operational vessel and emissions data into trusted, decision-ready insights,” said Espen Martinsen, Chief Commercial Officer at StormGeo. 

“As emissions regulations become more complex, this data is essential for transparent and efficient compliance management. By working with OceanScore, we can help customers connect StormGeo’s validated operational data with commercial compliance processes, creating a more integrated and practical approach to emissions management.”

The signing ceremony took place at the StormGeo booth during Posidonia 2026 in Athens and was attended by representatives from both companies.

Both companies expect the cooperation to continue evolving alongside upcoming regulatory developments, including FuelEU Maritime, EU ETS, the upcoming UK ETS and future emissions-related frameworks affecting global shipping.

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”
