Layer 1
Xain Insight
It works from the purchases spreadsheet you export from your ERP: less than 10 minutes of your work. It measures all purchased-goods Scope 3 from day one, with physical factors rather than spend.
ISO 14067 certified methodology
Every layer, measured.ISO 14067 certified and verified by LRQA. Tool adapted for SBTi.
The technology is the same: one company’s product is another’s Scope 3. The services are not. If you measure what you sell, it is the product certificate. If you measure what you buy, it is Scope 3. No implementation.

The problem with spend-based calculation
The footprint of your product, not of your invoice.
Most Scope 3 calculations multiply what you spend by a sector average.
With that method, a more expensive product “emits” more even if it is identical. And the supplier who invests in decarbonising looks dirtier, because it charges more.
Xain calculates with physical factors: material, weight, process (including its energy) and transport. If the product does not change, neither does its footprint.

How it works
Three steps. No implementation.
You send what you already have
Drawings, technical sheets, photos, manuals, bills of materials or purchase lines. There is no need to ask your suppliers for anything.
- Web platform
- API and ERP
The engine calculates node by node
Each product is broken down into a tree of processes. Each node carries a physical factor and, where there is ambiguity, the most conservative one applies.
- Material
- Process
- Transport
You receive the certificate
With a registration number and traceability down to each node’s factor. By reference, SKU, colour, destination or delivery.
- ISO 14067
- Cradle to gate

Layer 2
Xain Precision
Calculation from technical sheets or drawings, focused on the purchase lines with the most impact, not on every line. This is the level of the product footprint certificate.
Layer 3
Primary data
When a supplier provides its real data, it replaces the generic data. And it is reused for all of its customers on Xain.
The certificate
Every figure, traceable.
The certificate is not a closed number. Every kilo of CO2e can be followed back to the material, the process and the factor that produced it.
- A unique registration number for each certificate
- A node tree with the physical factor of each one
- The most conservative factor applies when in doubt

Origin
Born on the factory floor.
Xain comes from Intrustial, an industrial company that, within the PERTE VEC programme, built a platform to manufacture using industrial capacity distributed across many suppliers.
To split each part across hundreds of machines, that technology learned to read drawings and specifications. Measuring the CO2 of each material and process was the next step.

Frequently asked questions
What people usually ask us.
What is a product carbon footprint?
It is the sum of a product’s greenhouse gas emissions, expressed in kgCO2e per unit. Xain calculates it cradle to gate, from raw materials until the product leaves the factory, according to ISO 14067.
How is physical calculation different from spend-based calculation?
Spend-based calculation multiplies what you pay by a sector average, so the footprint rises with the price. Physical calculation starts from what the product is: material, weight, process (including its energy) and transport.
Do I need data from my suppliers?
Not to get started. Xain calculates from the technical documentation you already have. If a supplier provides primary data, it replaces the generic data and improves accuracy.
What does “ISO 14067 certified methodology, verified by LRQA” mean?
That the method Xain uses to calculate each footprint follows ISO 14067 and has been verified by LRQA, an independent body.
Is every carbon footprint an estimate?
Yes. No methodology knows the exact CO2 of each unit. The difference is the method: Xain estimates from the materials, processes and transport of the product, with a physical methodology in line with ISO 14067 and verified by LRQA, and not from the invoice amount.
