In order to best identify and reduce the negative environmental impacts derived from production activities of the habitat, the paramount approach is to study the environmental performance of products and services used in this rank. Type III environmental declarations are based on Life cycle assessment studies, whose purpose is to identify potential environmental impacts of products and services. Therefore, EPDs appear as a tool for assessing the product/services environmental information, assuring its scientific validity with verification by a third party prior to publication.
The DAPHabitat System appeared so as to cooperate in the creation and publication of this kind of documents in Portugal, being a national registration programme of Type III environmental declarations for the habitat.
The DAPHabitat system was built within the scope of a SIAC project, “approved within the framework of a Collective Efficiency Strategy of the Sustainable Habitat Cluster (QREN POFC 01/SIAC/2011 nº18653)”, and aimed to develop a national verification and registration system, of national and international visibility, for Environmental Product Declarations (EPD) specific for products of the habitat, based on objective and independent criteria, allowing for the implementation and availability of PCR (Product Category Rules) that substantiate the creation of EPDs that accurately validated on a database made available to the public.
