IPCC 2021(non-fossil CO2 uptake and emission)

Question

Hello,

I want to know what is the difference between IPCC 2021 GWP 100 and IPCC 2021 GWP 100(non-fossil CO2 uptake and emission).

How to choose when I calculate a product carbon footprint?

Answer 1

Well you need to add them to the LCIA method you are using, or use flows that are already known there, otherwise they will not contribute to LCIA results?
