I am using Ecoinvent 3.7 and calculating results using OpenLCIA methods 2.1.3 IPCC 2021
The name of the process is:
fibre production, flax, retting | fibre, flax | Cutoff, U
Now, I can see that there this process uses flax production | flax plant, harvested | Cutoff, U as its input process, which in turn uses the flow Carbon dioxide, in Air as one of its input.
When I check the LCIA results I cannot find the flow Carbon dioxide, in Air included in the calculation. I have tried the same calculation with all LCIA methods available to me: EF2.0, EF3.0, ReCiPe midpoint, TRACI, EDIP2003, but the problem persists.
Am I correct in thinking that these methods do not address biogenic carbon sequestration?
If not, is there a right way to include carbon sequestration during calculation using any of the available LCIA methods?
I went through multiple papers which suggest how to account for carbon sequestration, but I did not find a way to implement it in OpenLCA.
Thank you very much in advance for answering the question.
