Introduction
As in EN 15804:2012+A2:2019, in addition:
This document for gypsum-based products contributes to the further specification and harmonization of
public information regarding the environmental impact of gypsum products. In this way, the current
document also intends to contribute to a more transparent and smooth exchange of EPDs on a European
scale. It offers a common reference for the review of existing PCRs, already developed by several EPD
Program Operators, and a basis for the future development of PCRs, e.g. at the national level. It
complements the core product category rules for all construction products and services as established in
EN 15804:2012+A2:2019.
This document:
— specifies the functional and/or declared unit to be used;
— defines the default system boundaries for gypsum-based construction products;
— defines allocation procedures for the environmental impact of recycling and/or the use of by-
products;
— describes the default scenarios and rules for defining scenarios for each of the life cycle information
modules A-D;
— provides guidance for the determination of the reference service life (RSL) for gypsum-based
construction products.

5 General aspects
5.1 Objective of the PCR for gypsum-based construction products
As outlined in EN 15804:2012+A2:2019, an EPD which is in line with the core PCR provides quantified
environmental information for a construction product or service on a harmonized and scientific basis.
The objective of this c-PCR is therefore to provide additional guidance and/or common rules specifically
for gypsum-based construction products. These additional rules are intended to be used together with
the core product category rules for construction products, which are outlined in
EN 15804:2012+A2:2019.
5.2 Types of EPD with respect to life cycle stages covered
3
The declaration of the product stage modules A1-A3, A4, A5, B, C1, C2, C3, C4 and D is mandatory , as per
EN 15804:2012+A2:2019.
5.3 Comparability of EPD for construction products
As in EN 15804:2012+A2:2019. When comparing EPDs for construction products or assembled product
components, one should also consider standards of ancillary products, such as illustrated in Figure 1.
Figure 1 — Overview of standards related to plasterboards, products from secondary processing
and ancillary products (cf. EN 520:2004+A1:2009 and EN 15283:2008+A1:2009)

Wherever tables under module B are filled in with 0, programme operators should have the possibility to delete
the respective tables.

As in EN 15804:2012+A2:2019, in addition:
In the EPD, it should be clearly indicated whether the EPD is based on site-specific data or whether it
contains average data for a sector/group of plants from the same or different companies.
NOTE A group of manufacturers can be represented by an European and/or National Association with gypsum
product manufacturers on the members list.

6.2 Life cycle stages and their information modules to be included
6.2.1 General
As in EN 15804:2012+A2:2019.
6.2.2 A1-A3, Product stage, information modules
As in EN 15804:2012+A2:2019, in addition:
NOTE Product stage A1 includes raw material extraction and processing, and processing of secondary material.
For the gypsum industry, this covers - but is not limited to – the provision of natural and synthetic gypsum, natural
and synthetic anhydrite and recycled gypsum. In this module raw materials like recycled gypsum (from
construction and demolition waste) or potential waste paper use are accounted for as secondary material
(indicator SM).
Other types of synthetic gypsum, like FGD gypsum, fluoric acid anhydrite, and other types of gypsum
which are generated in other industrial processes are not declared as secondary material (see Table 1),
although they substitute the use of natural gypsum and therefore reduce the environmental impacts of
excavating natural gypsum tremendously. Since synthetic types of gypsum apart from recycled gypsum
are by-products from other industrial processes, they are not wastes and therefore cannot be accounted
5
for as secondary material after purification and reaching end-of-waste status .
5
FGD gypsum is identified as a by-product from combustion. Reference: [1] in bibliography.

6.3.3 Declared unit
As in EN 15804:2012+A2:2019, in addition:
The use of a declared unit is often more appropriate for construction products, which are part of a
building and applied in various situations, uses and construction types. The reference is indeed
independent from specific situations and conditions of the use stage, which is for instance not addressed
in modules C1-C4 and module D of an EPD in a cradle to gate (with options).
Table 2 and EN 15804:2012+A2:2019 shall be referred to for the use of functional units.
