Hi,
In the openLCA LCIA method package 1.5.4, there is an assumption that life cycle models can account for all carbon sinks and sources. There is therefore a characterization factor of -1 CO2e/kg for "Carbon dioxide, in air/resources/in air" and +1 for biogenic Carbon dioxide emissions.
HOWEVER: TRACI gives a factor of +1 for "Carbon dioxide, biogenic/air/x" and "Carbon dioxide, from soil or biomass stock/air/x", but does not have a corresponding "-1" "Carbon dioxide, in air/resources/in air".
In passing, there are these weird "Carbon dioxide, in air/air/all subcomp" flows that have CFs of +1. Do these really represent emissions? The "in air" suffix really seems to indicate that we are taking about a resource that has been categorized in the "air" compartment.
Regards,
Hugues

Thanks for uncovering this.
Green Delta, are there any plans to put out a corrected TRACI version? Those who have read this post can go correct the method themselves, but it would be useful to provide a corrected copy to other users.
