Generic spend-based factors use broad industry averages that don’t account for product-specific manufacturing processes. ClimateBase™ Spend factors are maritime-specific, derived from IMEF-aligned LCA models and other custom-built emission factors tailored to specific maritime procurement categories. ClimateBase™ PCF values reflect actual supplier-calculated product carbon footprints — the most accurate data available. The Δ% column shows how much generic factors overestimate emissions compared to primary data.
Example only — actual emissions may differ. Generic spend-based factors use broad industry averages; ClimateBase™ factors are derived from IMEF-aligned LCA models and supplier-calculated PCFs.

Decarbonization
Better data to support Net-Zero ambitions
ReFlow developed the IMEF guidance paper for IMPA SAVE, establishing the activity-based methodology for calculating Scope 3 emissions in maritime procurement. ClimateBase™ is the data infrastructure that makes IMEF compliance operational.
“The IMEF framework finally gives us a credible, standardised way to measure Scope 3 in maritime procurement. ClimateBase™ makes it operational.”

Who it's for
For Shipowners
Replace generic DEFRA or ecoinvent factors with maritime-specific emission data. Build your Scope 3 baseline on factors aligned with how vessels actually operate and procure — and keep it consistent year over year.
For Suppliers
Calculate your product carbon footprint through ClimateHub™ and publish it directly into ClimateBase™. Your data reaches shipowners and procurement teams without extra integration work.
Why ClimateBase
ClimateBase isn't just a data layer — it's a commercial advantage for shipowners managing compliance and suppliers competing for contracts.
Shipowners
Replace fragmented consultant engagements with a single auditable data source — and get expert support included.
Free yearly audit support
Your ClimateBase subscription includes annual audit assistance — no separate ESG consultant retainer needed.
Weeks → hours on data collection
Centralised supplier PCF data eliminates manual chasing. All data in one place, one format, audit-ready.
Compliance confidence
ISO-aligned, CSRD-ready data structure. Reduce risk of reporting gaps across IMO, EU ETS, and CSRD frameworks.
Lower ESG data management cost compared to traditional consultant-led approaches
Suppliers
Publish your PCF data once — get discovered by the procurement teams that are already looking for verified suppliers.
Free product QR codes
Get a QR code for each product linking to verified climate data. Print it on packaging, add it to spec sheets.
Visible to leading procurement teams
Your products are published towards procurement professionals via IMPA and ProcureShip — the platforms they already use.
Answer once, satisfy all customers
Stop filling different PCF request formats for every buyer. Publish once on ClimateBase — all procurement teams get the same verified data.
Shipowners across multiple platforms — get your products in front of procurement teams managing 2,300+ vessels via IMPA SAVE and ProcureShip
Whether you are a shipowner reporting Scope 3 or a supplier calculating product carbon footprints, ClimateBase™ gives you the emission factors you need, today.
Book a DemoWhat categories does ClimateBase™ cover?
ClimateBase™ covers emission factors for the main maritime procurement categories — including lubricants, paints, provisions, spare parts, and other vessel consumables. Coverage is expanding as more suppliers publish through ClimateHub™.
How often is the data updated?
Emission factors are updated when new supplier PCF data becomes available or when underlying LCA models are revised. Spend-based factors are reviewed annually to reflect methodological improvements.
How do I integrate ClimateBase™ into my reporting?
Shipowners access ClimateBase™ through ClimateDock™ or via direct API integration. Emission factors can also be pulled through the EmissionPassport™ platform for third-party tool compatibility.
What does it cost?
Pricing depends on scope and integration method. Book a demo to discuss your setup — we will walk you through options for shipowners, suppliers, and platform partners.
