As part of their transparent approach, SOPREMA published four environmental product declarations (EPD) covering more than a hundred roofing membrane products. The company also published five eco-declarations validated by the independent third party Vertima, which will soon be followed by three others currently being validated. Ten Health Product Declarations (HPD) have also been published. Among these, the HPD for SOPRA-ISO was selected as part of a third-party validation pilot project with the Health Product Declaration Collaborative, which is a first among Canadian manufacturers for this certification.
