Hello!
I am currently using openLCA in combination with ecoinvent database for my LCA calculations. I noticed that for some compounds, the impact factors for their emissions into the environment are only available for certain LCIA methods. For example, in my case, I am using ReCiPe 2016 (Mid-Point) as my LCIA method but there is no impact factors available for n-methylpyrrolidone (NMP) for ReCiPe. Nonetheless, I noticed that there impact factors for NMP emission for other LCIA methods.
I am wondering whether it is possible to convert these impact factors into values with units that are compatible with the ReCiPe method. If not, do you have any suggestion on other ways to include the emission of compounds without impact factor into the LCA calculation?
I would really appreciate if someone could advise on how to go about this situation. Many thanks, have a nice day! =)
