closed loop, LCA, impact categories

Question

Hello, how do you check in an LCA that you have achieved a CO2, water closed loop? Which impact categories can you use for water (water use or water consumption)?

Answer 1

Not sure I fully understand the question, but for both categories you have an uptake and release, and for water use, release of water reduces the impact, for CO2, in CML, uptake in biogenic systems reduces the impact. Does that answer your question?
