The scenario before the decision, not after.
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.


Create as many simulations as you like and keep them in Trama
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: 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.
