I will use an example here. When analysing my results in the contribution tree tab,  I can see that the chickpea cultivation process contributes to 18.13% of the impact category. However, when clicking on it, all showed processes involved in this cultivation step only add up to 10.38%. Is it because there are other processes that each contribute very small percentages each to the 7.75% missing that are not shown?

Many thanks for your help

Hi, if there's no other processes further down the list, then the "missing" 7.75% should be the direct emissions of the "Chickpea, at farm..." process itself.

All the others which are shown on the tree, are the indirect or upstream emissions from the processes that are providers to this process.
