Maritime decarbonisation is usually discussed as a fuel problem, a vessel problem or a financing problem. For Africa, it is also a coordination problem.

Governments can announce targets. Shipowners can investigate cleaner fuels. Ports can consider shore power and alternative-fuel infrastructure. Banks can develop green-finance products. Regulators can prepare for new reporting requirements. Technology companies can build monitoring and optimisation tools.

But if each actor works from a different dataset, different assumptions and different view of risk, the transition becomes more expensive than it needs to be.

That is the problem this article addresses.

What if an African government — or, better still, a public-private coalition spanning maritime administrations, ports, shipowners, fuel suppliers, financiers and technology providers — built a shared digital platform for maritime decarbonisation?

Not another dashboard.

Not a carbon-credit marketplace pretending to solve emissions by moving numbers around.

Not a government database that collects reports and creates little operational value.

Instead, imagine a trusted digital infrastructure capable of answering five questions continuously:

What is the fleet actually emitting?
Why is it emitting it?
Which interventions would reduce emissions most effectively?
Which operators and projects should receive financing or incentives?
Can the resulting emissions reductions and compliance claims be verified?

That platform would not decarbonise a vessel by itself. Software cannot replace cleaner fuels, efficient engines, hull improvements, renewable power, new port infrastructure or capital investment.

But it could do something equally important: make the transition measurable, comparable, financeable and governable.

For African shipping, that may be the difference between paying a premium to comply with a global transition designed elsewhere and building some of the infrastructure through which that transition is managed.

The regulatory clock is moving, even though the final rules are not settled

The International Maritime Organization’s 2023 Strategy on Reduction of GHG Emissions from Ships aims for international shipping to reach net-zero greenhouse-gas emissions by or around 2050, taking different national circumstances into account. It also sets indicative checkpoints: total annual GHG emissions from international shipping should fall by at least 20%, striving for 30%, by 2030, and by at least 70%, striving for 80%, by 2040, compared with 2008. The Strategy further calls for zero- or near-zero-GHG fuels, technologies and energy sources to represent at least 5%, striving for 10%, of the energy used by international shipping by 2030.

The proposed IMO Net-Zero Framework is intended to translate part of that ambition into mandatory measures. The draft approved at MEPC 83 in April 2025 combines a progressively tightening global marine fuel standard with a GHG emissions pricing mechanism. It would measure a ship’s annual GHG Fuel Intensity (GFI) on a lifecycle, or well-to-wake, basis.

Formal adoption has not yet occurred. The extraordinary MEPC session convened in October 2025 was adjourned, and negotiations continued in 2026. At the latest intersessional working group, held from 1–4 September 2026, delegates continued considering concerns and proposed amendments but deferred several matters to the next session in November. ISWG-GHG 23 is scheduled for 23–27 November 2026, ahead of MEPC 85 from 30 November–3 December. The adjourned extraordinary session is scheduled to resume on 4 December, subject to the outcome of MEPC 85.

That uncertainty should be taken seriously. It would be wrong to describe the draft framework as settled law.

But it would be equally wrong to conclude that African maritime stakeholders can wait for every comma to be agreed before preparing. The direction of regulation is already visible: emissions performance is becoming more granular, lifecycle fuel attributes matter increasingly, and the economic consequences of carbon intensity are moving closer to vessel operations.

In other words, maritime decarbonisation is becoming a data-intensive operating environment.

Africa does not start from zero — but the information is fragmented

International shipping already has a global data architecture. Since 2019, ships of 5,000 gross tonnage and above have been required under the IMO Data Collection System (DCS) to collect and report fuel-oil consumption and other specified information. Since 2023, DCS data has also been used to calculate ships’ operational Carbon Intensity Indicator (CII).

The system is deliberately structured around regulatory reporting. Aggregated ship data is reported to flag States, verified, and transmitted to the IMO Ship Fuel Oil Consumption Database. Public outputs are anonymised, and vessel-identifying data is not generally public.

That is appropriate for an international regulatory system. But a national or regional decarbonisation strategy needs a different layer of intelligence.

A maritime administration may need to understand the age and efficiency profile of its domestic and internationally trading fleet. A port authority may need to know whether investment in shore power, methanol bunkering, ammonia handling or renewable electricity is likely to be used. A bank needs to understand whether a proposed retrofit is likely to deliver credible savings. An operator needs to compare the cost of maintenance, voyage optimisation, hull work, machinery upgrades and fuel switching. A ministry needs to know whether a subsidy programme is reducing emissions or merely reducing private costs.

Those are related questions, but today they are often answered from separate systems — if they are answered at all.

The result is not merely an information gap. It is a capital-allocation gap.

The real question is not only “Who pays?” It is “Who knows what is worth paying for?”

Decarbonisation will require money. There is no credible version of the transition in which cleaner fuels, vessel retrofits, fleet renewal, port upgrades, electrical infrastructure, training and digital systems are free.

So the instinctive policy question is: who pays?

Shipowners? Cargo owners? Consumers? Governments? Development banks? Carbon-pricing revenues? International climate finance?

All of them may bear some portion of the cost.

But before deciding who should pay, governments need to know what should be paid for.

Consider two vessels that consume similar amounts of fuel. One may have an ageing engine operating close to its technical limits. The other may be suffering from poor hull condition, inefficient speed profiles and avoidable waiting time outside congested ports. Giving both operators the same decarbonisation grant because their annual fuel consumption looks similar could be wasteful. The first may need capital-intensive retrofit or replacement. The second may deliver meaningful reductions through maintenance and operational optimisation.

Now scale that problem from two ships to an entire national fleet.

This is why a digital decarbonisation platform should not begin as a reporting tool. It should begin as a decision infrastructure.

The proposed solution: an African Maritime Decarbonisation Intelligence Platform

For the purpose of this blueprint, call it the African Maritime Decarbonisation Intelligence Platform (AMDIP). The name is less important than the architecture.

The platform would sit between five groups:

vessel owners and operators;
ports and fuel or energy suppliers;
maritime administrations and environmental regulators;
banks, development-finance institutions and climate-finance providers; and
technology, engineering, classification and verification providers.

It would not require all parties to see all data. That would be commercially unrealistic and, in some cases, legally inappropriate.

Instead, the platform would establish a governed exchange in which data is collected once where possible, verified to an agreed standard, and used at different permission levels for operational, regulatory, financing and policy purposes.

The blueprint at a glance

Input	Intelligence Layer	Decision	Outcome
Fuel and energy data	GHG intensity calculation	Compliance pathway	Lower regulatory exposure
Engine and machinery data	Performance analytics	Maintain, retrofit or replace	Better capital allocation
Voyage and port-call data	Operational-efficiency analysis	Optimise speed, routing and arrival	Reduced fuel waste
Fuel certification data	Lifecycle emissions traceability	Select eligible fuel pathways	Credible GHG claims
Fleet and asset data	National readiness benchmarking	Target incentives and infrastructure	Smarter public policy
Verified project results	Abatement and payback analysis	Finance proven interventions	More bankable decarbonisation

The most important principle is simple:

Measure → Diagnose → Recommend → Finance → Implement → Verify → Learn.

Every successful intervention should make the next investment decision better.

Layer 1: A trusted vessel and emissions data fabric

The foundation would be a digital profile for each participating vessel.

Depending on vessel class and available equipment, that profile could combine:

vessel particulars and machinery characteristics;
fuel type and fuel-consumption records;
distance travelled and hours underway;
speed and voyage information;
engine-load and performance data;
maintenance and dry-docking history;
hull and propeller condition where available;
CII and related energy-efficiency information;
fuel certificates and lifecycle-GHG attributes;
port-call and waiting-time data; and
verified retrofit or efficiency projects.

The platform should not reinvent internationally mandated reporting. Where lawful and technically possible, it should integrate with existing reporting processes and authorised data sources rather than force operators to enter the same information repeatedly.

For smaller domestic vessels not covered by the same international reporting thresholds, the platform could support a lighter data model appropriate to local operations. That matters because Africa’s maritime transition is not limited to large oceangoing ships. IMO CARES has specifically highlighted the importance of domestic shipping in Africa and the Caribbean, including the need for national action plans, fleet renewal, green technologies, financing and collaboration among governments, ports, technology providers and industry.

The design principle should therefore be proportionality: sophisticated enough to support credible decisions, but not so burdensome that smaller operators are excluded from the transition.

Layer 2: A compliance and carbon-intensity engine

A reporting platform tells users what happened. A decarbonisation platform should tell them what it means.

The compliance engine would convert verified operational and fuel information into understandable indicators: current GHG intensity, CII trend, projected performance under different operating assumptions, and — once final rules are adopted — likely exposure under applicable IMO requirements.

It should also allow scenario testing.

What happens if the vessel reduces average speed on a particular route? What if waiting time at anchorage falls? What if a different fuel blend is introduced? What if an efficiency retrofit cuts fuel use by a modelled percentage? What if the fuel pathway has a different well-to-wake GHG intensity?

The objective is not to give operators a magic “compliant/non-compliant” button. Maritime operations are too complex for that.

The objective is to turn regulation into something managers can model before they spend money.

Layer 3: A technology recommendation engine — but not an AI oracle

This is where the platform becomes more ambitious.

Using vessel characteristics, operational data and verified technology-performance information, it could produce a ranked set of possible interventions.

For one vessel, the priority might be hull cleaning and propeller maintenance. For another, engine tuning or waste-heat recovery. Another might benefit from improved voyage planning, weather routing or just-in-time arrival. A harbour craft could be suitable for battery hybridisation. A different ship might be approaching the point at which a major retrofit no longer makes economic sense and replacement should be considered.

Artificial intelligence can assist here, particularly in pattern detection, anomaly identification and predictive modelling. But it should not be allowed to become a black-box engineering authority.

Recommendations affecting vessel safety, machinery configuration, fuel choice or major capital expenditure should remain subject to qualified engineering assessment, class requirements, safety regulation and human approval.

A credible African platform should be technologically ambitious and institutionally conservative where safety is concerned.

Layer 4: From “green finance” to evidence-based finance

One of the largest opportunities is financial.

Many decarbonisation projects fail before implementation because the operator cannot prove the business case convincingly enough to a lender or investor. At the same time, financiers may struggle to distinguish a genuinely effective efficiency project from a proposal built around optimistic assumptions.

A platform could create a standardised decarbonisation project passport.

For each proposed intervention it could contain:

verified vessel baseline;
technology description;
expected fuel saving;
expected GHG reduction;
capital cost;
estimated payback period;
technical dependencies;
safety and class requirements;
supplier or installer information;
measurement and verification plan; and
post-implementation performance.

Over time, this creates something Africa badly needs: a growing evidence base showing which maritime technologies actually work under African operating conditions.

That evidence could help commercial banks price risk, help development-finance institutions identify scalable projects, help governments design incentives and help operators compare investment options.

The proposed IMO Net-Zero Fund makes this even more relevant. Under the draft framework, pricing revenues would be used for purposes including rewarding low-emission shipping and supporting innovation, research, infrastructure, technology transfer, training and capacity building, with attention to developing and vulnerable States. The final design remains subject to negotiations, but the direction creates a clear strategic question: will African countries have sufficiently mature, evidence-backed projects ready to absorb available finance when opportunities emerge?

A platform cannot guarantee funding. It can make projects more legible to funders.

Layer 5: Fuel traceability and the coming chain-of-custody problem

Shipping’s fuel transition will require more than recording what was pumped into a tank.

The IMO’s lifecycle approach considers emissions associated with fuel production as well as use onboard the ship. This is why discussions about fuel certification and “chain of custody” matter.

Two fuels with similar names may have very different lifecycle emissions depending on how they were produced, what feedstock or electricity source was used, how they were processed and transported, and how their sustainability attributes are certified.

In 2026, IMO specifically scheduled expert work on chain-of-custody models to track fuel origin and movement through supply chains so emissions can be properly traced and verified.

That is a warning to every country hoping to become a future green-fuel producer.

It will not be enough to produce methanol, ammonia, hydrogen-derived fuels or biofuels and call them “green”. Their emissions attributes will need credible evidence.

An African maritime decarbonisation platform could therefore connect vessel demand with fuel certification and supply-chain data, creating a domestic layer of traceability that aligns with international requirements rather than attempting to replace them.

This could become particularly important for African countries with ambitions to produce renewable marine fuels. The value is not only in producing molecules. It is in producing trusted molecules with auditable attributes.

Layer 6: A national maritime carbon map for infrastructure decisions

The public-policy value of the platform appears when individual vessel data is aggregated responsibly.

A government should not need to know a shipowner’s commercially sensitive operating details to understand national trends.

With appropriate anonymisation and access controls, policymakers could see questions such as:

Which vessel classes account for the largest share of measured emissions?
Where are the oldest and least efficient assets concentrated?
Which ports experience the greatest avoidable waiting or congestion-related fuel use?
Which routes appear suitable for electrification or hybrid vessels?
Where could shore power have sufficient demand?
Which ports are credible candidates for alternative-fuel bunkering?
What proportion of the fleet appears retrofit-ready?
Which interventions are generating the lowest cost per tonne of GHG avoided?
Where are financing applications failing?
Which skills shortages are slowing deployment?

This changes the nature of policy.

Instead of announcing a generic “green shipping fund”, government could target support toward vessel classes or technologies where verified data shows a clear barrier.

Instead of building alternative-fuel infrastructure because it is fashionable, a port could use demand scenarios and fleet profiles to determine whether the investment is commercially plausible.

Instead of treating maritime and energy policy as separate domains, ministries could identify where port demand, renewable-energy production and shipping routes intersect.

Layer 7: Ports as energy and data nodes

Ports should not be treated as passive endpoints in this architecture.

They are where vessels, cargo, energy, regulation and infrastructure physically meet.

The IMO’s own 2023 GHG Strategy identifies port developments, shore-side power and infrastructure for zero- or near-zero-GHG fuels as relevant elements of the transition. Meanwhile, the IMO-European Union “Future-Ready Shipping in Africa” project explicitly links decarbonisation with digitalisation, Maritime Single Window readiness, data interoperability, alternative-fuel infrastructure and bankable green-corridor projects in Sub-Saharan Africa.

That connection is important.

A Maritime Single Window is primarily designed to streamline the exchange of information required when ships arrive, stay in and depart from ports. A decarbonisation platform would have a different purpose. But the two should be designed to interoperate where appropriate.

Port-call timestamps, berth availability, vessel arrival information and operational coordination can all influence fuel consumption. IMO-backed technology demonstrations have already explored port-call data sharing for just-in-time shipping, where improved arrival coordination can reduce unnecessary speed and waiting.

The broader lesson is that digitalisation and decarbonisation are not separate agendas.

When a ship burns fuel because data did not move quickly enough between ship, terminal and port, an information failure has become an emissions problem.

Who should own the platform?

This is where many otherwise promising technology concepts fail.

If a private company owns the entire platform, regulators and competitors may question neutrality. If government owns and operates everything, commercial users may fear surveillance, procurement cycles may slow development, and innovation can become bureaucratic. If every industry actor builds a separate system, interoperability disappears.

The most credible model is likely a governed public-private digital utility.

Government or the maritime administration would define the regulatory purpose, legal basis, minimum data standards and public-interest outcomes.

An independent operating entity or licensed consortium could manage the technology under transparent service standards.

Classification societies, accredited verifiers or authorised organisations could support data assurance.

Technology providers could build interoperable modules rather than being forced into one national software monopoly.

Operators would retain defined rights over commercially sensitive data.

Banks and development institutions would access only the information needed for approved financing use cases.

Researchers and the public could receive aggregated, anonymised insights where disclosure serves policy and transparency objectives.

The architecture should separate data custody, regulatory authority, platform operation and commercial services.

That separation is not technical decoration. It is the trust model.

Data governance will matter as much as the algorithm

A platform carrying vessel operational data, financial information, fuel records and compliance indicators would quickly become critical maritime infrastructure.

Its governance should therefore answer difficult questions from the beginning:

Who owns raw vessel data?
Who can access identifiable records?
Can regulators use commercial data for enforcement if it was originally submitted for financing?
How long is data retained?
What happens when an algorithmic recommendation is wrong?
Who certifies fuel attributes?
How are conflicting datasets reconciled?
Can an operator challenge an incorrect emissions record?
How are cybersecurity incidents handled?
Can foreign technology vendors export or reuse national maritime data?

These issues cannot be postponed until after launch.

The system should use role-based access, strong identity controls, encryption, tamper-evident audit logs, documented data lineage and explicit consent or statutory authority for each use case. Its APIs should be governed by published standards. Cybersecurity should be treated as a safety and sovereignty issue, not merely an IT requirement.

Africa does not need a maritime decarbonisation platform that creates a new dependency by sending its most valuable operational data into opaque foreign systems.

The platform should not become a surveillance system

There is another danger.

When governments gain access to more operational data, the temptation is to collect everything because it might become useful later.

That would be a mistake.

The platform should follow a principle of purpose limitation: collect what is needed for defined regulatory, financing or optimisation use cases, at the minimum granularity required.

Commercial confidentiality should not be treated as an obstacle to climate action. It should be designed into the architecture.

For example, a ministry may need to know that a class of coastal tankers has poor average carbon performance. It does not necessarily need unrestricted access to the complete commercial voyage history of every company operating those vessels.

Trust will determine participation. Participation will determine data quality. Data quality will determine whether the platform becomes useful.

Start with Nigeria — but design for interoperability across Africa

Nigeria would be a logical proving ground for this concept because of the scale and complexity of its maritime economy: international shipping, coastal operations, offshore activity, major ports, petroleum logistics, a growing digital-policy agenda and significant future energy-transition questions.

But a Nigerian platform should not be designed as a digital island.

Shipping is inherently cross-border. Fuel supply chains cross jurisdictions. Regional corridors connect multiple ports. Vessel ownership, flag, class, finance, insurance and cargo interests may all sit in different countries.

The World Bank has recently highlighted a broader African problem: customs, transport, standards, payments, services, energy and digital platforms often remain fragmented across national borders. Maritime decarbonisation should not repeat that architecture.

The better approach is to build nationally, standardise regionally and interoperate internationally.

A Nigeria-first implementation could expose documented APIs and common data definitions that other African maritime administrations could adopt voluntarily. Regional economic communities or the Association of African Maritime Administrators could then help align standards without requiring every country to use the same vendor or database.

The goal should not be one giant continental computer system.

The goal should be an interoperable African maritime decarbonisation network.

What the first version should actually do

Ambitious government technology projects often fail by trying to build the final vision immediately.

A credible minimum viable platform should do far less.

Phase One: Establish the baseline.

Recruit a defined pilot fleet and participating ports. Build verified digital vessel profiles. Capture fuel, voyage and operating data using existing records and onboard systems where available. Produce standardised performance baselines.

Phase Two: Diagnose opportunities.

Introduce analytics that identify high-confidence efficiency interventions: maintenance, hull condition, speed patterns, waiting time, machinery performance and reporting gaps.

Phase Three: Connect finance.

Create project passports for a limited number of retrofit and optimisation opportunities. Partner with banks or development institutions to test whether verified data improves underwriting.

Phase Four: Verify outcomes.

Measure actual post-intervention performance against the baseline. Record where expected savings were achieved, exceeded or missed.

Phase Five: Scale the intelligence.

Only after the data model and trust framework are proven should government expand toward national benchmarking, infrastructure planning, fuel traceability and more advanced compliance modelling.

This sequence matters because the platform’s most valuable asset will not be its software.

It will be the credibility of its data.

A platform cannot solve the hard physical constraints

Technology thinking becomes dangerous when it treats software as a substitute for physical reality.

A digital platform cannot manufacture green methanol.

It cannot create renewable electricity where the grid is inadequate.

It cannot finance a vessel owner with an unbankable balance sheet.

It cannot make an unsafe retrofit safe.

It cannot train seafarers merely by displaying a skills gap on a dashboard.

It cannot eliminate the price differential between conventional and low-GHG fuels.

And it cannot resolve international negotiations over the final IMO Net-Zero Framework.

What it can do is expose those constraints clearly enough that capital and policy are directed at the real bottlenecks.

That is a different and more defensible promise.

The bigger opportunity: turn compliance infrastructure into industrial capability

Africa’s strategic objective should not be to build software merely so African ships can comply with rules developed elsewhere.

The deeper opportunity is to use regulatory pressure to create new domestic capabilities.

A functioning decarbonisation intelligence ecosystem would create demand for:

marine IoT and sensor integration;
vessel-performance analytics;
cybersecure maritime data infrastructure;
fuel lifecycle and sustainability verification;
marine engineering and retrofit expertise;
energy-efficiency auditing;
AI-assisted maintenance and optimisation;
green-finance underwriting tools;
port-energy modelling;
alternative-fuel safety expertise;
classification and assurance services; and
maritime data science.

Those are industries.

If African governments approach decarbonisation only as a compliance burden, much of that capability will be imported. If they treat it as a technology and industrial-policy challenge, some of the value can be built locally.

This is already consistent with the direction African maritime administrations have articulated. At the 2024 Association of African Maritime Administrators conference, participating administrations identified maritime decarbonisation, workforce capacity and sustainable financing among regional priorities. IMO and EU initiatives are also linking decarbonisation, digitalisation, port infrastructure and skills development in Sub-Saharan Africa.

The missing layer is the system that allows those efforts to inform one another.

Who pays for maritime decarbonisation?

Ultimately, everyone connected to maritime trade may pay something.

Shipowners will invest in vessels and operations.

Fuel suppliers will invest in new production and distribution systems.

Ports will invest in infrastructure.

Governments may fund enabling systems and targeted incentives.

Financiers will price transition risk.

Cargo owners may pay premiums for lower-emission transport.

Consumers may absorb some of the cost through trade.

International mechanisms may redistribute part of the burden and reward cleaner pathways.

But the most expensive transition is one in which everybody pays without knowing whether the money is reducing the right emissions.

That is the case for shared digital infrastructure.

Not because data is more important than fuel.

Because data determines whether fuel, technology, finance and policy are being used intelligently.

Africa should build the intelligence layer before it needs it

The IMO negotiations will continue. The final framework may change. Pricing details may change. Implementation timelines may change. Guidance will continue to evolve.

Africa should follow those negotiations closely and participate actively.

But there is a category of preparation that does not need to wait.

Governments can improve maritime data governance.

Ports can improve digital interoperability.

Operators can establish credible fuel and performance baselines.

Banks can develop evidence standards for maritime transition finance.

Universities can train maritime data, energy and engineering specialists.

Technology companies can build interoperable tools around African operating realities.

And maritime administrations can begin designing the trust architecture through which all of those actors exchange information.

The platform described here is therefore not a prediction that one particular government will build one particular system.

It is a blueprint for a capability Africa is likely to need.

The question is whether that capability will emerge deliberately — through African institutions, standards, technology companies and maritime expertise — or whether the region will eventually rent it from platforms designed for somebody else’s market.

At AD Marina, we believe maritime technology should do more than digitise existing processes. It should help institutions make better decisions about the next generation of maritime infrastructure. That is what “Navigating Innovations” means in practice: identifying the operational problem early, understanding where technology genuinely helps, and designing solutions from Africa that can ultimately serve the world.

Frequently Asked Questions

Is the IMO Net-Zero Framework already legally binding?

No. The draft framework was approved at MEPC 83 in April 2025, but the extraordinary adoption session was adjourned in October 2025. Negotiations continued in September 2026 and are scheduled to continue in November ahead of MEPC 85 and a possible resumed extraordinary session on 4 December 2026.

Would a digital platform itself make ships net zero?

No. Physical emissions reductions still require efficiency improvements, cleaner energy, new fuels, vessel retrofits, fleet renewal, port infrastructure and other real-world interventions. The platform would help measure performance, identify priorities, coordinate stakeholders, support financing and verify outcomes.

Why not simply use the IMO Data Collection System?

The IMO DCS is a regulatory system for collecting specified fuel and operational data from covered ships and informing IMO policy. A national or regional decarbonisation intelligence platform would serve additional operational, financing, infrastructure-planning and technology-assessment use cases while respecting the boundaries and confidentiality of existing regulatory systems.

Who should operate such a platform?

A public-private utility model is likely more credible than either complete private control or complete government operation. Government can define standards and public-interest outcomes, while independent operators, verifiers and technology providers deliver interoperable services under clear data-governance rules.

Could the platform begin in Nigeria?

Yes. Nigeria has sufficient maritime complexity to support a meaningful pilot, but the technical architecture should use open standards and documented interfaces so that it can interoperate with systems in other African maritime economies rather than becoming another national data silo.
