ReCiPe CF error in ecoinvent 3.1 LCIA method pack from nexus

Hi openLCA team, I think I may have stumbled on an error in ReCiPe midpoint H's water depletion potential characterization factors for the ecoinvent 3.1 methods through the nexus. According to Goedkoop et al (2012, pg. 112), the CF's should be the same (= 1) for each resource, except "water, unspeci...

Re: Excel export and contribution tree

Update: I received information from another user about how to accomplish this on a Mac. Instructions below: - Update version to 1.4.2 (or latest version) - highlight some of the contribution tree table, even 1 cell will do - type command-A to “select all” and then - right click in the selected stuff...

Re: Excel export and contribution tree

Hello,

I am a Mac user and cannot seem to even copy-paste the contribution tree results. I've tried both command-c and shift-c to try to highlight the output, and I can't get anything to stick. Has anyone else had this issue? Is there a way around it?

Many thanks,

Nicole

Re: Uncertainty

Hi Andreas,

Thanks for the reply. I'll get in touch offline about the new calculation. Also, I'm a relative novice in the area of uncertainty assessment, so I don't think I'll be able to contribute to expanding it - sorry!

Best,

Nicole

Re: exchange database between versions 1.3.4 and 1.4

If I am using v 1.4.1, and I have a .olca file, is there a method available to convert to .zolca without installing 1.3.4 and MySQL?

If not, it would be nice to have a similar plug-in for v. 1.4.1...

Thanks for your help.

Best,

Nicole

Re: Uncertainty

Hello, I'm trying to understand how openLCA assesses uncertainty and what the software is capable of. I have reviewed the forum posts, openLCA wiki and some literature, and it is still unclear to me. I have a few questions: 1) On the openLCA wiki, it states that Gaussian approximations are used to c...
