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.
What 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.
Whether you are a shipowner reporting Scope 3 or a supplier calculating product carbon footprints, ClimateBase™ gives you the emission factors you need, today.
