Long term emission contexts

[MaximeAgez]

Hello, I think contexts for long term emissions could be included in the FEDEFL to match with what the ecoinvent database uses as elementary flows. Currently, as LCIA method developers wanting to connect to the FEDEFL, we can only assign the same characterization factor for both long term and unspecified term emissions. For LCIA methods which differentiate short and long term impact categories (like Impact World+) it leads to an overestimation, since long term emissions are not forced to zero in short term impact categories. Thank you :)
