If you work in shipping today, you already see how quickly the industry is changing as decarbonisation moves from discussion to operational reality. For decades, the sector relied on heavy fuel oil and incremental efficiency improvements. That approach is no longer enough. Governments, regulators, cargo owners and investors are now pushing shipping towards deep emissions reductions.
The direction of travel is already visible in the regulations. The International Maritime Organisation (IMO) has set a target for net-zero greenhouse gas emissions from international shipping by 2050, with interim reduction goals for 2030 and 2040. Regional measures, such as the European Union Emissions Trading System (EU ETS) for shipping, are also reshaping commercial decisions.
But turning those ambitions into real operational change is not straightforward. The industry is still debating which fuels will dominate, how infrastructure will develop and how quickly regulations will tighten. For shipowners and operators, the difficulty is that investment decisions often have to be made long before the long-term fuel landscape becomes clear. Ships ordered today may still operate in the 2040s, yet the energy systems that power them are still evolving.
Transition cannot be viewed as a purely technical issue. New fuels, regulations and technologies only work if professionals operating ships and managing fleets understand how these changes fit together. Maritime decarbonisation is therefore not limited to engines or fuels. It is also about knowledge.
International shipping currently produces around 2.8–3% of global greenhouse gas emissions, according to the Fourth IMO Greenhouse Gas Study. The number may seem small, but in absolute terms it is comparable to the annual emissions of a major industrialised country. Tackling global shipping challenges is now a regulatory and commercial priority, but the pathway forward remains uncertain. If you are involved in ship operations, fleet management or maritime policy, several key questions remain unresolved:
For many industry professionals, this uncertainty affects everyday decisions. The challenge for the future of the sustainable maritime industry is not a lack of ambition, but a lack of shared understanding about how the transition will work in practice.
The global maritime decarbonisation discussion has largely focused on technology. New fuels, new propulsion systems, wind-assisted propulsion, digital route optimisation and more efficient vessel designs are all part of the transition.
Every solution introduced to shipping must work within the realities of regulation, safety, operations and commercial pressure. Without that understanding, even promising technologies may fail to deliver expected results. If your organisation begins working with new fuels, the implications quickly become clearer.
The same applies to operational efficiency technologies. Digital technologies can make shipping safer and smarter and improve fuel efficiency. However, only if crews and fleet managers understand how to interpret the data and apply it to real voyages. Energy efficiency devices can reduce consumption, but their benefits depend on consistent operational practices across the fleet.
In practice, decarbonisation requires professionals who understand how technology, regulation and operations interact. It will succeed when the people operating ships and managing fleets understand how to use that equipment safely, efficiently and in line with evolving regulations.
As the pace of change accelerates, the maritime industry is beginning to face a widening gap between existing expertise and the knowledge required for a low-carbon future. Many professionals currently working in the industry were trained in an operating environment built around conventional fuels, and that foundation remains essential. However, the transition to lower-emission shipping introduces new areas of knowledge not traditionally part of maritime education.
Industry organisations have already highlighted the scale of the challenge. The International Chamber of Shipping (ICS) estimates that up to 800,000 seafarers may require additional training to work safely on alternative fuels. If you work in ship operations, compliance or fleet management, understanding global marine engineering trends and measures such as the following is essential:
Without structured education in these areas, decarbonisation can become difficult to navigate. Decisions about fuels, vessel upgrades or operational changes may be made with an incomplete understanding of the technical, regulatory or commercial implications. This is not a question of commitment. The challenge today is ensuring that professionals across the industry have the knowledge needed to navigate a transition that is still unfolding.
MLA College recognises that maritime decarbonisation will influence the work of both current and future maritime professionals. To support this shift, we will introduce a specialist module on maritime decarbonisation to our MSc Sustainable Maritime Operations programme in May 2026, including:
The aim is to help you understand how decarbonisation affects real maritime operations and decision-making across the industry.
The transition to lower-emission shipping will ultimately depend on professionals operating ships, managing fleets and shaping industry strategy. Education helps you build the knowledge needed to:
As the maritime sector moves towards net-zero emissions, that knowledge will play a critical role in turning industry ambition into real operational change.
Explore MLA College’s MSc Sustainable Maritime Operations programme to learn how maritime professionals can support the transition to lower-emission shipping.
Decarbonising shipping involves new fuels, regulations, technologies and operational practices. Education helps maritime professionals understand these changes and apply them safely and effectively in real operations.
Professionals in the maritime industry will need knowledge of alternative fuels, emissions regulations, lifecycle analysis of fuels, energy-efficiency technologies and the commercial and policy frameworks shaping shipping’s transition.
International shipping produces around one billion tonnes of CO₂ annually, accounting for about three per cent of global greenhouse gas emissions, according to the International Maritime Organisation (IMO). If we do not take action, this percentage could rise by as much as 50% by the middle of the century as global trade increases.
New fuels, technologies and regulations introduce operational and safety challenges. Training helps professionals understand how to work with these systems safely and meet evolving regulatory requirements.
MLA College is launching a specialist maritime decarbonisation module for our MSc Sustainable Maritime Operations programme in May 2026 to help students and professionals understand the policy, technology and operational changes shaping sustainable shipping.
