How can I create a dummy process with known environmental impacts ?

Question

Hello

I would like to create a process of recycling of plastics, where I know the final environmental impacts with the EF3.1 method, but I don't have access to the inventory.

Is it possible to create a 'dummy' process, with no inventory but, environmental impacts results for the EF3.1 ?

Thanks a lot,

Joana

Yes, if you want the impact results to contribute to your overall calculation, you can create elementary flows like "Climate change", "Acidification" ... add them with the impact results as the amounts to a process and also add these elementary flows with a characterization factor of 1 to your impact categories of interest.

A more elegant way is to create a new result, add the impact categories of interest (and the impact values) to the new result data set. Afterwards you need to link the result data set in the model graph to your product system and you need to make sure that you calculate your product system with the same impact method / the same impact categories as your created result data set.

Thanks a lot Conrad, I will try both methods.
