Greetings
I know that this question is not directly for OpenLCA or databases, but I think there will knowledge from the community on this one.
I am creating an EPD for a product, that all of the raw materials have EPD of their own, so I can use their results.
What happens though, is that the EPDs of the suppliers will expire at some point during the 5year validity period of my EPD. What should I do then?
During my annual EPD revision, would be viable to continue using their expired EPD results or should I change raw material data through a generic process from ecoinvent?
And then, when and if they make a new EPD, should I revise my EPD again and use their data?
