I think, perhaps foolishly, that we may have some products that can meet this requirement, but can only move forward if I can answer two key questions:
1. What is the baseline from which the product is optimizing? Is it the industry EPD? or something else unnamed? Conceivably if it's the industry standard EPD, a product specific Type III EPD might be able to show the improvement desired.
2. What does the narrative requirement encompass? Will the EPD itself serve as the narrative? Or do we need to ask the manufacturer for something entirely different that hasn't been published?
