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...) ?
