Hello, 

The results at the contribution tree (at the product system) are not the same as the results (at the project level). I created the process myself and got 3.89E6 kgCO2eq for climate change (long term) at the contribution tree and 4.95E6 kgCO2eq at the results, for example. I have added the providers from Agribalyse and the model graph seems ok, so I cannot see what else could have gone wrong. I use the same impact assessment method [i.e., ImpactWorld+ (midpoint)] and functional unit in both cases. Why would this be? 

Screenshots of the contribution tree (product system) and results (project) for climate change (long term) are below:

Thank you for your help!

Thanks for your help, that was the issue! I see that 'None' was selected at the project level but 'As defined in processes' at the product system. When I select 'As defined in processes' at the project level, I see the same results!
