Ecoinvent versions

[Nathalie-Revit]

I am getting my own ecoinvent access for AB I have one question.
AB requires Ecoinvent 3.10, correct?
The new Simapro version provides access to ecoinvent 3.11. I could get access from there. Does that difference in version matter?
I could install and use Simapro with ecoinvent 3.11 and use the access to ecoinvent also for AB, but I need to know if that works.
What exactly do I need to consider, or what should I be aware of, or does it not work at all?
If I knew about those issues beforehand, that would really help me. Thanks in advance.

Hi Nathalie,

Activity Browser is also compatible with ecoinvent 3.11. Could I ask where you heard/read the compatibility with ecoinvent 3.10 only? This may mean we have to update some documentation somewhere 😅.

However, ecoinvent 3.10 and 3.11 are only available when you start a new project. You cannot import them into existing projects.

If you have more questions, just let us know!

I just double checked on this page: https://github.com/LCA-ActivityBrowser/activity-browser/wiki/Getting-Started
There is always the ecoinvent 3.10 shown. This is why I asked about the compatibility. Thanks for the quick response.

I see, thanks for letting us know!

Hi, i'm trying to install ecoinvent3.11 database from a local file but it's always indicated that it's not compatible with biospher version.
Any help would be appreciated

Hi Nadeem,

Ecoinvent 3.11 is only available to start a new project with, not for installing locally. This has to do with data licensing restrictions and is not something we can resolve unfortunately.

@marc-vdm do you think this why I was getting this issue importing local ecoinvent 3.11 with Brightway? brightway-lca/brightway2-io#321

[marc-vdm]

I would assume so, yes.

Thanks, I will add to the issue with a suggestion to mention this in the docs.
Best,
