Import of cumulative LCIA results

[moritzos]

Hi,

In a Brightway2 project, I would like to import several activities (e.g. production of a gas) by using the Excel Importer, for which I only have cumulated LCIA results in the LCIA method CML. I therefore have data on their environmental impacts in the CML categories, but do not know the LCI data. The mentioned activities are again inputs of other activities in the project (e.g. the gas is used in another process). In the end I want to analyse the LCIA results of different activities using the CML method. Does anyone know how I can best import the activities for which I only know the cumulative LCIA results (and not the LCI data) so that I can use them in the further calculations?
