Maritime Decarbonisation Verification & IMO GFI Readiness
Independent verification and advisory support for shipowners, marine fuel suppliers, port operators and energy companies navigating FuelEU Maritime, EU ETS/MRV, IMO GHG Fuel Intensity readiness and sustainable alternative fuel claims.
FuelEU Maritime
Support for well-to-wake GHG intensity calculations, fuel pathway evidence and compliance documentation for vessels calling at EU ports.
EU ETS & MRV
Review of emissions data, monitoring evidence and verifier-ready documentation for maritime emissions reporting and allowance surrender preparation.
IMO GFI Readiness
Preparation for the IMO Net-Zero Framework and GHG Fuel Intensity requirements using a practical lifecycle emissions approach.
Why maritime decarbonisation verification matters
Shipping emissions are no longer only an environmental reporting issue. They are becoming a measurable compliance, commercial and fuel procurement issue for shipowners, charterers, bunker suppliers and energy producers.
Maritime stakeholders must now demonstrate reliable emissions data, credible lifecycle GHG calculations and traceable sustainability evidence for low-carbon and alternative marine fuels.
Trans Cert helps organisations understand their emissions profile, verify marine fuel lifecycle data and prepare documentation for applicable regulatory and customer requirements.

Marine fuel lifecycle assessment scope
The climate performance of a marine fuel depends on more than onboard combustion. A credible assessment should consider the complete lifecycle of the fuel.
| Lifecycle stage | What is assessed | Typical evidence required |
|---|---|---|
| Well-to-tank | Feedstock extraction or cultivation, processing, fuel synthesis, upgrading, transport, storage and bunkering before the fuel is used on board. | Feedstock records, production data, energy use, supplier declarations, transport data, sustainability documentation and emission factors. |
| Tank-to-wake | Emissions from onboard fuel use, including carbon dioxide, methane and nitrous oxide where applicable. | Bunker delivery notes, fuel analysis, engine data, consumption records, voyage data, logbooks and calculation methodology. |
| Well-to-wake | Total lifecycle GHG intensity across fuel production, supply and onboard use, expressed per unit of energy where required by the applicable programme. | Calculation file, methodology note, emission factors, traceability records, uncertainty assessment and supporting documentation. |
Alternative marine fuels we can support
Different fuels require different evidence. Trans Cert supports lifecycle GHG assessment and sustainability documentation for a wide range of marine fuel pathways.
Our verification approach
A structured process helps clients move from raw operational data to credible, reviewable and decision-ready emissions information.
Confirm scope
Define the vessel, fuel pathway, reporting period, regulatory driver, assurance level and deliverables.
Map evidence
Identify fuel, voyage, production, supply chain and sustainability records required for the assessment.
Review calculations
Check boundaries, emission factors, conversion factors, assumptions, uncertainties and data controls.
Assess risks
Evaluate data gaps, claim risks, non-conformities and areas where methodology clarification is required.
Report findings
Issue a technical report, advisory memo or verification statement depending on the agreed scope.
Improve readiness
Provide practical recommendations to strengthen future monitoring, reporting and compliance preparation.

Frequently asked questions
Clear answers for shipowners, fuel suppliers and maritime stakeholders starting their decarbonisation verification journey.
What does GFI mean?
GFI means Greenhouse Gas Fuel Intensity. It refers to the greenhouse gas emissions associated with each unit of energy used by a ship. Under the IMO Net-Zero Framework, GFI is expected to be assessed using a well-to-wake lifecycle approach.
Is alternative marine fuel automatically low carbon?
No. A fuel’s climate performance depends on feedstock source, production method, transport, storage, energy inputs and onboard use. Lifecycle GHG calculation and traceability evidence are needed to support credible claims.
What information is usually required for a marine fuel GHG assessment?
Typical evidence includes bunker delivery notes, fuel specifications, fuel consumption records, voyage data, engine information, proof of sustainability, feedstock records, production energy data, chain-of-custody documentation and calculation files.
Can Trans Cert support FuelEU Maritime preparation?
Yes. Trans Cert can support lifecycle GHG calculations, evidence mapping, fuel pathway review and preparation of verifier-ready documentation for FuelEU Maritime. Regulatory submissions must follow the verifier and scheme requirements applicable to the client.
Does this page replace legal or statutory compliance advice?
No. This service page describes verification and advisory support. Final regulatory obligations depend on vessel type, trading pattern, flag, administering authority, fuel pathway and the specific regulation or scheme.
