White-Label EPD's

Hello,

I’m trying to create an EPD for one of our products. An EPD already exists from our supplier for a generic version of the product. Because they’ve used an average product, the declared unit values won’t match our product and I’m wondering what my options are if I am unable to get hold of the raw data from the supplier:

  1. I think I can create a white-label EPD according to the PCR rules? How does that work - do you just add that EPD under A1 materials and then is there an option to say it’s white-label during submission, do I have to declare it as white-label? The PCR rules say it has to be identical results but should include A4, so presumably the results aren’t entirely identical if you’re adding extra information?
  2. Am I able to scale up the EPD somehow so that the mass of the declared unit of our product matches that of the EPD? Or would I have to do that using a sister variant once I’d created a white-label EPD?

Thanks, any info is appreciated as there is nothing that I can see in the PCR rules or oneclick’s help/community sites.
