Is it just me, or is there not much to work with in terms of compliant carpet for Low-Emitting Materials in LEED v4? The USGBC's Third Party Certifications and Labels table inlcudes FloorScore and NSF-332 but these don't apply to carpet. The table also lists SCS and Greenguard but as far as I know, neither of these programs have any carpet that's been certified. There is no mention of either Green Label Plus or NSF-140. On GreenWizard, I can find only one product that claims to comply with v4 requirements, via the Collaborative for High Performance Schools path. That's it. Any insights/experience?
