Environmental Product Declarations (EPDs) make statements about the environmental impact of a product, such as energy and water consumption or the resulting global warming potential. These documents essentially serve as proof for building certification. This means that if buildings are certified according to sustainability systems such as DGNB, LEED or BREEAM, EPDs are required, among other things.
In order to support manufacturers of construction products in the creation of product-specific EPDs, ift Rosenheim, as the program holder, has created its own Product Category Rules (PCR) for various construction products. These serve as the basis for an EPD. The basis for this is DIN ISO 14025 as well as EN 15804 and the General Guideline for the Preparation of Type III Environmental Product Declarations prepared by ift Rosenheim.
In addition to the PCRs, a life cycle assessment (LCA) according to DIN ISO 14040 and EN ISO 14044 is required in order to draw up EPDs.
All advantages at a glance
The preparation of a product-specific, individual EPD is necessary if, for example, there is no average and/or model EPD for the product in question, or if building certification systems or the market require one.
In contrast to a model EPD, a specific EPD involves the determination and analysis of more extensive data. The specific EPD thus enables a detailed and representative description of the product, with which special features are also described for the entire life cycle. For this reason, a specific EPD is particularly appropriate as a differentiating feature and for increasing opportunities in invitations to tenders.
Mandatory findings are required as part of an EPD according to EN 15804+A2 for manufacturing, disposal as well as for benefits and loads outside the system boundaries. The remaining life cycle phases can be considered optionally. Since all certification systems require information from different product life cycle phases, it makes sense to identify all the needs when preparing an EPD.
The verified Environmental Product Declaration applies exclusively for the products named in the declaration.

A PCR provides general rules for the preparation of the EPD and is structured like a regulation or guideline. The basis for the development of PCR documents are the standards DIN EN ISO 14025 and DIN EN 15804.
The Product Category Rules (PCRs) of ift Rosenheim are divided into two parts and marked accordingly. Part A contains general rules and the separate Part B contains product group-specific rules. The PCRs are to be used in the preparation of EPDs according to the program operation for the preparation of Environmental Product Declarations (EPDs) of ift Rosenheim.
