Any help would be appreciated regarding the following questions: I was wondering if any definition is given for the "industry average"? Also, how are the EPDs supposed to help in this direction, as the majority of them are cradle-to-gate, and therefore can not be compared with each other? Finally, why most of the PCRs advise to go with a cradle-to-gate, wouldn't it be more helpful if they would advise to go with a cradle to grave (provided they give some recommandations about the reference life.. etc...) ?

Most building materials are conducted within the scope of cradle to gate for manufacturers so it can be compared but some of them go beyond and conduct say for example disposal or reuse which are up to manufacturer. I think it is right decision to exclude use, maintenance, repair etc as it is diffucult to measure. The most important part is eaw material supply, transportation and manufacture.....

Thank you for your answer, I fully understand that use and maintenance are difficult to evaluate.
But what about the lifetime ? isn't there a risk that products of poor quality that can easely break would get a better environmental score, even though they need to be changed more often?

Same question here: what is the "industry average" and where to look for it?

The only definitive compliance path I have seen with respect to Option 2 is found in LI 10415 (https://www.usgbc.org/content/10415)
How can products contribute to earning Option 2 of the LEED v4 MR credit BPDO – Environmental Product Declarations?
In addition to the option outlined in the credit language, products that meet any of the following requirements can also contribute towards Option 2:
1. Demonstrate reduced impact with a product-specific EPD against an industry-wide generic EPD, provided the manufacturer was part of the study and the two conform to the same PCR.
2. Demonstrate reduced impact of the same product, over time, with two product-specific EPDs.
