Simulate the impact of a supply-chain choice before you make it.
The simulator takes a product that has already been measured and varies one process, material or transport leg. It returns the indicator side by side with the original, in the same units, and states how the document-backed share of the figure changes.
Before you change a supplier or a material, see how much the garment's footprint changes.
Create as many simulations as you like and keep them in Tramaproof
Before you change a supplier or a material, you can see what effect it will have. Simulations recompute the product's impact on the assumptions you set, without touching the real data.
The country enters the calculation
The same process carried out elsewhere produces a different indicator, because each country makes its electricity differently: the national electricity mix is a parameter, not a constant.
The figure improves, the evidence may not
A lower impact does not always mean sounder data. The same view shows both: how much the product improves, and how much of it is documented.
What you can change
Each component of the product, one line at a time: its material, its share of the garment and, where the reference data price a recycled version of that fibre, its recycled content. The country and the supplier of spinning, dyeing and making up, chosen among your own suppliers for that stage. And the transport mode, on the distance the product already has on record.
The result moves as you change a value. The product as it is and the product as simulated are computed by the same engine, on the same reference data, and shown side by side: the total in kg CO2e, the share of each stage and the difference per garment. The screen also suggests alternatives, such as moving a stage to another country or changing the transport mode, each with the difference it would make.
When the product appears on your production orders of the last twelve months, the difference per garment is also shown for the year. Without orders, the screen says so rather than guessing a volume.
What a simulation is, and what it is not
A saved simulation keeps its inputs and the result it produced, stamped with the version of the reference data used. If the reference data change later, the saved figure keeps meaning what it meant on the day it was written down.
A simulation is not a version of the product. It is never published, it reaches no passport and it proves nothing. Turning a scenario into reality means changing the product and collecting the new supplier’s documents, through the platform as usual.
Any scenario can be exported as a PDF working paper, to discuss with a buyer or a supplier, and saved scenarios can be duplicated, edited or deleted.
What it is for
Compare two spinners before you place the order
Move the spinning stage to another of your suppliers or to another country, and see the difference per garment with the documented share beside it.
Test a recycled fibre
Raise the recycled content of a component, where the reference data price a recycled version of that fibre, and see how much the total changes.
Check whether transport matters
In the example above, changing the transport mode saves 10 grams per garment, against 200 grams for moving the making up to Portugal. It is better to know which lever matters before negotiating a new route.
Frequently asked questions
Does a simulation change my product data?
No. A simulation recomputes the product’s impact on the assumptions you set and leaves the real data untouched. Nothing from a simulation reaches a passport.
Which reference data does a simulation use?
The same reference data and the same engine as the Impact tab. The simulated figure and the current one are measured the same way, so they can be compared directly.
Why can the documented share fall in a simulation?
Because a documented figure belongs to the supplier who documented it. If you move a stage to another supplier or country, that supplier’s measured energy no longer applies, and the stage returns to a reference value until the new supplier sends its own document.
Can I share a simulation?
Yes, as a PDF: an internal working paper built from the scenario on the screen. It remains a simulation, not a statement about the product.
