Ι am using two providers for the same flow e.g. zinc coating, coils. One provider from Eugeos 15804 4.1 and one from Ecoinvent 3.9.1.
I use the EN 15804_A2 Impact assessment method to calculate the results.
I attach a link with a picture showcasing the results https://ibb.co/N9w92JZ
. The table on the left is Ecoinvent 3.9.1 and the one the on the right Eugeos.
The output flows, resources and waste indicators are pretty different, focusing on the Ecoinvent 3.9.1 ones that have value zero.
Can anyone please help me to decide which are better to take as credible and more trustworthy?
