I'm super new to LCA but have a question. I've performed an analysis to identify the life cycle of different solvents. I selected the different solvents and used the EF 3.1 which granted me a significant table of data.
I was searching for a way to weigh the data when i stumbled across a document of the European comission (
https://eplca.jrc.ec.europa.eu/permalink/2018_JRC_Weighting_EF.pdf)
Is it correct that i can just take the raw data from the EF and multiply it by the weighting factors determined by the EU, and use the sum of the outcome as a level of greenness for the different solvents?
e.g.
ozon depletion = 1.01 kg CFC11 eq, weighing factor = 22.19 so ozon depletion accounts for 22, whilst water use is 0.9 m3 with a weighing factor of 9, accounting for 2.7?
I found some papers about normalizing the data first, but i'm not sure if the data has already been normalized during the analysis.
thanks!
