Carbon per product, when a customer asks for it
Some customers now want a figure for each part you sell. Our team works it out with you, starting from the site energy you already measure in ESGen and adding materials, packaging and transport.
Steel bracket, one part
2.63 kgCO₂e, cradle to gate
Raw materials
1.84kgCO₂e/part
Processing
0.62kgCO₂e/part
Transport
0.11kgCO₂e/part
Packaging

A product figure you can stand behind
Built from your own records first, with the boundary and every source written down.
Built on figures you already measure
Site energy from the platform, each figure linked to its bill, is the starting point for process energy.
Materials from your own records
Drawings and purchase records give the weights. Secondary data fills gaps and is named as such.
The boundary stated plainly
Cradle to gate unless your customer asks for more, and the report says which.
Wording checked before you use it
Our team checks any claim you plan to make with the figure against the evidence.

How a product footprint is built
Five steps, from the product your customer named to a report they can check.
One product, one unit, one boundary
We agree which product, the unit (for example one finished part) and where the footprint stops. For parts sold to other businesses that is usually the factory gate.

Where the platform stops and our team starts
Carbon per product is scoped work. The platform supplies the measured site figures it is built on.
In the platform today
- Site energy figures with the bill behind each one
- Scope 1, Scope 2 and upstream energy by site
- Evidence library and calculation log
Done by our team
- Product carbon footprints, scoped with you
- Life cycle assessments, where a customer asks for more than carbon
- Checks of the wording of any claim you make with the result
ESGen does not verify or certify product footprints. Where your customer needs independent verification, it comes from a third party.
