Dear negin96moslemi,

Thanks a lot for your comment. I am very sorry for the delay of our response.

Unfortunately such a library including sample processes and systems are not available. As a matter of fact some researcher tried to develope that, and it was largely discussed, but never proceeded.

Maybe you could search in the ecoinvent database included in Umberto for certain unit processes and modifiy them.

If you need further assistance, please feel free to contact our support team at

Kind regards,

General / environment like github for some elementary parts?
« Last post by negin96moslemi on January 03, 2021, 18:22 »
Hi, hope you're doing well and happy new year.

I was wondering is there any environment having some pre-defined and drawn LCA that we can copy and use for our bigger LCA? For instance, the manufacturing process of bearing or gears?

I think that would be really helpful and time-saving, like some basic codes that are existed on Github.

Thanks in advance for your time and consideration.

Hallo Anfi,

vielen Dank für deinen Post. Bitte entschuldige, dass wir uns erst heute melden. Auf Grund eines technischen Problems, wurde der Post in unserer Ansicht nicht angezeigt.

Ist dein Problem noch aktuell? Wenn ja, schicke doch gerne eine Nachricht an Wenn möglich, schicke doch auch die Umberto Projektdatei mit.

Viele Grüße

Dear Yusuf,

Thanks a lot for your post. Unfortunately, this is currently not available in Umberto LCA+. However it will be implemented in Umberto 11, going to be released next year.

Already available is a multiple scenario analysis. You find a webinar recording right here:

Furthermore please find here some hints:

If you need any further support, please feel free to reply, or contact us at

General / Uncertainty Analysis Feature or Monte Carlo Simulation
« Last post by yusuf on October 14, 2020, 12:41 »
Is there any feature in Umberto LCA+ that can be used to evaluate the uncertainty in the environmental impacts?

To clarify, can tens/hundreds/thousands of different iterations be simulated to estimate the uncertainty of impacts such as Global Warming Potential, Acidification Potential and so on?

Uncertainty Analysis: Systematic procedure to quantify the uncertainty introduced in the results of a life cycle inventory analysis due to the cumulative effects of model imprecision, input uncertainty and data variability. [ISO 14044]

PS: A similar topic was created in 2014, but it has been inactive for a while.

General / Python in Umberto

Hallo, ich benötige dringend Hilfe!

Ich habe ein Problem. Ich versuche anstelle mit einer User defined function Berechnungen mit Python in Umberto durchzuführen. Dafür möchte ich Variablen verwenden, die ich auch in den Transitionen des Modells verwende. In Python kann er aber anscheinend nicht auf die Variablen aus dem Modell zurückgreifen und es kommt die Fehlermeldung dass sie nicht definiert sind.
Was muss ich tun, damit er auf die Variablen zurückgreifen kann?

im Anhang die Abbildung eines ganz simplen Beispiels und die Fehlermeldung.

Schonmal vielen Dank für Eure Hilfe!

General / Model into a transition?
« Last post by maphraw on June 13, 2020, 13:03 »
Hi there , I’m Jame.

in Umberto 5.6 it was possible to export a whole subnet or a whole calculated net into a spreadsheet, which you could import into a single transition and use this transition as a new one through export this transition.

I couldn't find a similar function in Umberto NXT LCA yet. Is there any possibility to create such a transition from exporting a spread sheet of a calculated net?

Thank in advance.

I am also very new to Umberto and was wondering if it is possible to Import EcoSpold Data to Umberto. The last post I have seen on this topic is from 2015. Surely there is a way to use free Datasets, not only by formatting it to an Excel sheet. Otherwise I would be almost completely bound to data I have to buy and this shouldn't be the state of the art. Don’t you agree?
