Can anyone tell me what certifications exist that "verify impact reductions below industry average" for the following?
• global warming potential (greenhouse gases), in CO2e;
• depletion of the stratospheric ozone layer, in kg CFC-11;
• acidification of land and water sources, in moles H+ or kg SO2;
• eutrophication, in kg nitrogen or kg phosphate;
• formation of tropospheric ozone, in kg NOx or kg ethene; and
• depletion of nonrenewable energy resources, in MJ.

Good question! I would add that credible certifications and standards must be incorporated to give this Credit some teeth and effectively move things forward. Self-reporting manufacturer policies may work for marketing products and may be well intentioned, but for benchmarking and metrics that bring value and credibility to LEED - not so much.

My question is more focused on understanding how we would find these certifications and document this credit. Since I am not familiar with any certifications that currently exist that document three or more of the listed attributes or furthermore how one would be able to "verify impact reductions below industry average." I don't understand how industry averages will be determined for all the different green building products we typically see on a project.
Since no current programs are listed, it seems optimistic to think they will be developed and approved in two years. Also, "50% by cost of the total value of permanently installed products" seems extremely high and impossible to meet.

I also have the same question as Pamela, What certificates are required to "verify impact reductions below industry average" for Option 2 of Building Product and Optimization - EPD?
Can anyone provide an example of evidence put forward for this option.
