Hi all!

I have a doubt about EPD, could someone help me?

This credit explains that products with LCA (ISO 14044) or EPD (ISO 14025) that have at least cradle-to-gate scope are valued as 1/4.

My doubt is: In this case, can the manufacturer do the product declaration WITHOUT external verification? Auto-declaration is enough?

Thanks.

By my understanding, a manufacturer's self-documentation is not enough. An example of an ISO 14044 EPD valued at 1/4 is the Athena Sustainable Materials Institute LCA of concrete. http://www.nrmca.org/sustainability/epdprogram/Downloads/NRMCA%20LCA%20P...

I hope that this helps.

FAQs about MRc2:

For the twenty products with EPDs, can I count multiple products from the same manufacturer?

If I include a product with an EPD in Option 1, do I have to also include it in the scope of products that are part of the Option 2 calculation?

If I include a product in the BPDO EPDs credit, do I also have to include it in the BPDO Material Ingredients credit?

Do I have to submit the full EPD with my documentation for Option 1?

Where can I find a list of products with EPDs?

How do you recognize each type of EPD?

If a company provides an EPD but it does not mention on it that it meets the ISO standards required, can we still submit it for LEED or do we need to have that verification?
