Cladding Industry Agrees to One Rulebook for Conducting LCAs
Cladding is the latest product category for which a general industry product category rule (PCR) has been set, joining others like concrete and flat glass. PCRs designate the rules for life-cycle assessment calculations if they are to be used for environmental product declarations (EPDs).
This cladding PCR is of particular interest because it supersedes 14 different material-specific PCRs already on the market, a situation that has led to dubious claims about which systems and materials have the lowest life-cycle impacts (see Cladding: More Than Just a Pretty Façade).
Now that the rules have been standardized across the industry, resulting EPDs are more likely to be a useful comparative instrument.
