International Seaways on Making the Business Case for Decarbonization

What makes a decarbonisation investment worth it?In our latest Sea Through Efficiency episode, we sit down with Lina Tenenbaum, Lead Sustainability Engineer at International Seaways, to explore how the company approaches decarbonisation across its fleet.From energy efficiency and emerging technologies to vessel performance, data and ROI, we discuss why the right solution is rarely the same for every vessel, and how a strong understanding of the fleet can help turn potential opportunities into sound business decisions.“We look at everything that’s out there, but we have to assess it on a case-by-case basis.”A conversation about looking beyond the technology itself, and focusing on what actually makes sense for the vessel, the operation and the business.

How do you invest in decarbonization when the future is still uncertain?That was one of the key questions we explored in the latest episode of SeaThrough Efficiency, where we spoke with Richard TyrrellThe conversation goes beyond the usual discussion around regulations and alternative fuels. Instead, it focuses on the practical decisions shipowners are making today.🎙️ In this episode, we discuss:• Why regulations like CII have changed behaviour, even if they're far from perfect.• The challenge of investing in technologies for assets that will operate for decades.• Why operational efficiency remains the strongest foundation for decarbonization.• The realities of alternative fuels, and why point-to-point corridors may be the most practical path forward.• The critical role of reliable data, verification and transparency in building confidence to invest.As Richard puts it:"There's a real need for good data, verification and certification processes that give people the confidence to invest."The transition to net zero won't happen through a single breakthrough. It will be driven by thousands of practical, data-backed decisions that improve efficiency today while preparing for tomorrow.How do you invest in decarbonization when the future is still uncertain?That was one of the key questions we explored in the latest episode of SeaThrough Efficiency, where we spoke with Richard TyrrellThe conversation goes beyond the usual discussion around regulations and alternative fuels.

Innovation is no longer the challenge in shipping. Adoption is.In the latest episode of Seathrough Efficiency, we sat down with Krishnan Narayanan to discuss the newly announced collaboration between MarineFifty and Njord, and why the industry is entering a new phase focused on scalable, measurable efficiency solutions.From independent validation and real-world performance measurement to the role of collaboration in accelerating decarbonization, the conversation explores why energy efficiency technologies are becoming one of shipping’s most practical “no-regret” pathways forward.“What the industry really lacks is a consistent, trusted way to validate performance in the real world, without that, scaling technologies becomes extremely difficult.” - added Krishnan

FuelEU Maritime is here, but compliance is far from straightforward.In this episode, we break down how the regulation works, the key timelines to keep in mind, and the different pathways to stay compliant, from pooling and banking to biofuels and beyond.We also explore what really matters: how to choose the most cost-effective strategy depending on your vessel, trading pattern, and access to fuels.Because under FuelEU, compliance isn’t just about avoiding penalties, it’s about making smarter commercial decisions.

Navigating maritime regulation just got more complexIn our latest podcast, we spoke with Francesco Sandrelli, Policy Director for Environment at the UK Chamber of Shipping, about the evolving regulatory landscape and what it means for shipowners and operators.Key takeaways:Fragmentation is real: International vessels now juggle multiple emissions schemes and local requirements.Data drives compliance: Performance metrics and operational strategies are central to staying on top of regulations.From targets to action: Global climate goals are clear, but turning them into fleet-ready solutions is the challenge.Decarbonization isn’t just about technology, it’s about navigating complex regulations, monitoring data, and making strategic decisions across your fleet

In our latest episode of SeaThrough Efficiency, we speak with Nina Porst, Executive Director for Sustainable Ships and Skills at Danish Shipping, about how shipowners are approaching decarbonization in a complex and evolving regulatory landscape. The conversation explores:The role of national and international regulation, including developments at the International Maritime OrganizationWhy regulatory clarity is essential for long-term investment decisionsWhat actions are available to shipowners today, particularly within energy efficiency and retrofitsRather than focusing on long-term scenarios alone, the discussion centres on practical steps that can be implemented now, while the broader fuel transition continues to develop.

In our latest SeaThrough Efficiency episode, Managing Director Frederik Pind shares what Njord’s acquisition by V.Group means for our mission, and for the industry’s journey toward net‑zero.With MEPC 83 postponed, uncertainty has grown, but the need for decarbonization hasn’t changed. By combining V.Group’s global compliance and operational expertise with Njord’s specialization in energy efficiency technologies, we’re building a stronger, end‑to‑end decarbonization platform for shipowners worldwide.

In our latest episode of Njord’s Podcast, we speak with Sophie Parker, Transport Economist at the World Bank, about how energy efficiency can accelerate emissions reductions in shipping.The discussion explores why efficiency measures, across operations, ports, and onboard technologies, remain one of the most actionable levers available today, while also highlighting the organizational and commercial challenges that slow adoption.Key topics include:The impact of operational and port efficiency on emissionsWhy organizational readiness matters as much as technologyHow data, financing models, and standards can support wider uptakeListen to the full episode to explore how shipping can move forward through efficiency.

2025 was a pivotal — and at times frustrating — year for maritime decarbonization.In this episode of Seathrough Efficiency, Njord’s Managing Director Frederik Pind reflects on the momentum, delays, and lessons that defined the year, and what they mean for shipping as we move into 2026.The discussion explores why regulatory uncertainty from the IMO continues to challenge the industry, why energy efficiency remains a no-regret pathway regardless of policy timelines, and how wind-assisted propulsion emerged as one of the most commercially impactful technologies in 2025. The episode also highlights a critical but often overlooked barrier to decarbonization: organizational alignment and decision-making within shipping companies.Looking ahead, the conversation unpacks what shipowners and operators should prepare for in 2026 — from increasing regulatory complexity and regional carbon pricing schemes to the growing importance of acting early rather than waiting for perfect clarity.This episode is essential listening for anyone navigating shipping’s transition to a low-carbon future.

Driving Decarbonization with Data: Union Maritime’s SeaLabsIn our latest Seathrough Efficiency episode, hosted by Caroline Evert, our Business Development Manager, we spoke with Kishan Mutu, Head of SeaLabs, about how Union Maritime is scaling sustainable tech through structured planning and data-driven decisions. Some of the key points are: ✅ Wind-Assisted Propulsion: 5 vessels equipped, 30 more committed✅ High-frequency data + ROI modeling = smarter investments✅ Proactive retrofits: planning starts 12 months before dry dockKey takeaway: Innovation isn’t just tech, it’s process. SeaLabs is a blueprint for navigating uncertainty and leading the low-carbon transition.
