How to add a process with impact analysis?

Question

Hi,

Since the materials listed in the free database are limited, I want to add a new process. I gathered some information about environmental impacts of the material, but I cannot edit  contents in the tab 'impact analysis' in a new process. How can I solve the problem? (I am using the Environmental Footprint database)

Thanks!

Hi, the impact analysis is calculated automatically, for impact assessment methods that you have also imported, and is not meant to be edited. Idea is to demonstrate how the process will contribute to an LCA calculation.

How can I solve the problem?

=> you should import an LCIA method.

Hth, Andreas

Mh, Thank you for your answer Andreas, but I encounter the same issue, and this doesn't solve the problem. If we want to add a new process, knowing only its impacts on the various impact categories, and not the full inventory of inputs and outputs, how can we do so in OpenLCA ?
