Hello, we are using the EF2 dataset available on Nexus to perform LCAs of different systems in the framework of a European project. I have several questions related to your EF2 dataset, please, can someone from the developer team answer?

  1. can you explain better the linking approach we should follow? Is there a way to check if everything is linked properly?
  2. Why if I look for some process in the LCDN nodes I frequently observe differences in respect to what is implemented in your DB?
  3. Is there a way to adapt the EF3 method from JRC into your dataset? To avoid the use of the peflocus, EF converter and Look@LCI
Thank you to anyone will answer.

For the EF database, you should not link anything automatically since they are agrgegated system processes so far (in the released version), which however have some input products sometimes. Linking these automatically does not make sense. For transport, there are unit processes, but they also should be linked manually.

We will release an EF3 version soon also because others have done it now too, we were waiting for a consistent set of EF3 LCI datasets.

Of course, if the process was created in a different software, our implementation could look differently. Do you have an example maybe?

Yes I agree this is a bit a hard pathway. You can do this also by other ways but as said we will also provide EF3 (data as far as available, and LCIA method) soon.

All the best,

Thanks for the feedback.

Yes, for example, I found this http://lcdn.thinkstep.com/Node/showProcess.xhtml?uuid=db14c527-8ab6-4f5c-b21c-d5c789e94d82&stock=Free_GaBi_data on LCDN but I can't find equivalent in your EF2. Why?

Do you have timing for EF3 availability? I want to check if compatible with our deliverable.

Another question, if you can answer. Which is, briefly, the working flow to pass from LCDN nodes to OLCA database?

Thank you
