Water consumption contribution tree from Recipe 2016 (H) doesn't add 100%

Question

Hello there,

I am running a drip irrigation model, adjusted from the Ecoinvent drip irrigation for Peru data. I am assessing it using Recipe 2016 Midpoint (H) in open LCA ver. 1.10.2. However, on the results, the contribution tree categories for water consumption do not add 100%. Even, running drip irrigation -PE without modification, it doesn't add 100% for this category. Would you mind explaining why for this category I cannot see the total contribution from other processes, please?

Thank you very much in advance.

Maria

Which database do you use?

Check elementary flows impact: the contribution tree tab does not show you contribution from elementary flows. Instead, use the impact analysis tab to figure out the impact of elementary flows.
