Maritime Lifecycle Assessment (LCA)

Credible, regulation-ready climate data for ships, equipment, and maritime supply chains. ReFlow provides the software and expertise to make that calculation tractable, defensible, and directly useful for regulatory reporting, procurement, and decarbonisation decisions.

Container ship at sea — maritime vessel lifecycle assessment

Definition

What Is Maritime LCA?

Maritime LCA applies ISO 14040/44 methodology to vessels, marine equipment, and offshore structures — mapping environmental impacts from raw material extraction through fabrication, operation, maintenance, and end-of-life scrapping. Results are expressed in kg CO₂e per functional unit: per gross tonne, per tonne-nautical mile, or per installed unit of equipment.

Key Challenges

Why Maritime LCA Is Different

Ships are among the most complex products ever built. Five factors distinguish maritime LCA from most other industrial applications:

Long operational lifespans (20–30 years) make use-phase modelling dominant and sensitive to fuel pathway assumptions

Multiple fuel scenarios must be modelled in parallel: HFO, LNG, methanol, ammonia, and hydrogen produce radically different lifecycle profiles

System boundaries are contested: vessel, cargo, port calls, and supply chain all have legitimate claims on emissions allocation

End-of-life varies dramatically by geography — from certified recycling in Europe to uncontrolled beaching elsewhere

Regulatory frameworks (IMO, EU ETS, CSRD) use different scopes and reference years, requiring careful data architecture from the start

Our Approach

ReFlow’s Approach to Maritime LCA

ReFlow combines LCA software with maritime domain expertise. Our platform handles the data architecture — managing bills of materials, supplier emission factors, and ISO-compliant calculation logic. Our advisory team ensures the methodology is defensible, audit-ready, and fit for the specific regulatory or commercial purpose.

Procurement

Get PCF data from every supplier you work with

Procurement decisions shape a vessel’s carbon footprint long before it enters service. ReFlow enables shipowners to request, collect, and verify Product Carbon Footprint (PCF) data from equipment and component suppliers — in a standardized format aligned with ISO 14067 and ready for regulatory reporting.

Request PCF data from suppliers

Send structured data requests to equipment and component suppliers directly through the platform, with clear format requirements attached.

ISO 14067-aligned data format

Standardized methodology ensures supplier submissions are comparable, traceable, and audit-ready across your entire fleet.

Track supplier response status

Monitor which suppliers have submitted data, follow up on missing responses, and maintain a complete record for compliance and reporting.

Supplier PCF feeds into your vessel LCA

Verified supplier data integrates directly into your overall lifecycle assessment, closing the loop on Scope 3 emissions.

Use Cases

Who Needs Maritime LCA?

Demand for verified maritime emission data is now coming from four directions simultaneously: regulation, financing, procurement, and customer pressure.

Shipowners

Vessel carbon footprints for CSRD reporting, green loan eligibility, and portfolio decarbonisation targets

OEMs & Equipment Suppliers

Product-level PCF certificates for customer procurement requirements and EPD certification

Shipbuilders & Yards

Newbuild LCA for green financing, Poseidon Principles compliance, and sales differentiation

Maritime Suppliers

Component-level emission data for Tier 1 customer requirements and tender qualification
