As a user I want to be able to used EPDs in my LCA analyses without losing on accuracy and detail even when the specific EPD I want to use has not declared some stages like A4, A5, C etc.
A solution to this would be for eToolLCD to move from the exact EPDs or add a hybrid EPD solution. In this solution EPDs will be the bases for materials within the eTool database that will represent the declared product but eTool will supplement the non declared stages with industry average data. For example, in this case impacts like A4, C and replacements will be calculated based on the default input from eToolLCD or what is defined by the user in the same way as all generic material in the database.
