With the new Materials and Resources credits in LEED v4, Environmental Product Declarations and Health Product Declarations seem to be the way of the future for product documentation. However, when I search for them, I only seem to find envirodec.com and UL.com for the EPDs, and the Pharos HPD toolbox for the HPDs. Is this right? Are there databases where these are housed that I am not aware of? Or is there really very few EPDs and HPDs in existence today?
