How can I implement CO2 fixation into my LCA

Question

Hi everybody,

I have to model a simplified LCA of 1l of olive oil for my uni seminar "Environmental Impact Assessment". I want to include the CO2e fixation during the agricultural phase. My question is: Can I just use the natural flow "Carbon dioxide" (category: resource/in air) and put the value with a negative sign on the input side as CO2e is taken from the air and fixed in the trees and soil?

Thank you and kind regards,
Nina

P.S.: I am using ReCiPe 2016 Midpoint (H) for our calculations.

Hi Nina,

welcome - you should use the resource CO2 in air as input

a negative emission technically works too but does not reflect the real situation.

Best wishes,

Andreas
