GWP potential interpretation

Question

Hello.
I used OpenLCA to calculate the GWP of an integrated rooftop greenhouse vs a conventional greenhouse.
I wonder How can I interpret the result?
Is the 10kg co2 eq good or bad?
my functional unit is per m2 of heated greenhouse

Answer 1

Hi, good question, this underlines that LCA is a relative tool, so the point is not really to see whether 10kg CO2eq are bad or good (you can of course check the total emissions in Europe e.g. and set this in perspective, or normalise the results in the LCIA which also has this goal), but the point is more to compare your two products and see which one is better, and why.

Best wishes,

Andreas
