Hello Andreas,

thank you for your answer. I am not sure if I have formulated my question correctly. It is about the fact that I have received from a supplier

the results of an LCA for 1 t of product.

I would like to use these results (kg CO2e1, kg SO2e1, ...) and add the environmental impacts of our production process to these values (kg CO2e2, kg SO2e2, ...)

==>

kg CO2eSupplier + kg CO2e Own Process = kg CO2e final;

kg SO2eSupplier + kg SO2e Own Process = kg SO2e final, ...

Can this be done without further ado or should at least the underlying methods (impact assessment methods) be identical?
