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.
1 Scope
This document provides product category rules (c-PCR), that are complementary to
EN 15804:2012+A2:2019, for Type III environmental declarations for gypsum-based products for the
construction industry.
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.
NOTE 1 Annex B of EN 15804:2012+A2:2019 has been complemented in an annex to this document.
NOTE 2 An Annex F has been added to this document.

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
In addition to mandatory declaration as described in EN 15804:2012+A2:2019 the following stages shall
be declared: A4, A5 and B modules.
5.3 Comparability of EPD for construction products
The comparability of EPD for construction products shall be 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.

Wherever tables under module B are filled in with 0, programme operators should have the possibility to delete
the respective tables.
NOTE See EN 520:2004+A1:2009 and EN 15283:2008+A1:2009.

(EN 14496:2017);
— gypsum based adhesives for gypsum blocks (EN 12860:2001 );
— Binders, composite binders and factory-made mixtures for floor screed based on calcium sulfate
(EN 13454-1:2004/ EN 13454-2:2019).
6.1.4 Cast products

— preformed plasterboard cornices (EN 14209:2017).
6.2 Life cycle stages and their information modules to be included
6.2.1 General
As in EN 15804:2012+A2:2019.
Please note that product category rules available for the insulation part of composite or sandwich panels should
be considered as well.
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
for as secondary material after purification and reaching end-of-waste status .

6.3 Calculation rules for the LCA
6.3.1 Functional or declared unit
As in EN 15804:2012+A2:2019.
6.3.2 Functional unit
6.3.2.1 General
As in EN 15804:2012+A2:2019, in addition:
Requirements for the functional units and declared units of gypsum and gypsum-based products are
summarized in Table 1 (6.3.2).
6.3.2.2 Performance in a functional unit
As in EN 15804:2012+A2:2019.
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.
Table 2 gives examples of mandatory information for declared units.

6.3.4 Reference service life (RSL)
6.3.4.1 General
As in EN 15804:2012+A2:2019, in addition:
For gypsum products, there are no influences on ageing when the recognized codes of application are
followed. Therefore, the technical performance characteristics of gypsum-based products are usually
based on a minimum service life of 50 years . Other RSL values should be justified.
6.3.4.2 Scenarios for RSL and functional unit
As in EN 15804:2012+A2:2019.
6.3.5 System boundaries
6.3.5.1 General
As in EN 15804:2012+A2:2019.
6.3.5.2 Product stage
As in EN 15804:2012+A2:2019, in addition:
In the case of input of secondary materials or energy recovered from secondary fuels, the system
boundary between the system under study and the previous system (providing the secondary materials)
is set where outputs of the previous system, e.g. materials, products, building elements or energy, reach
the end-of-waste state.
Reference: [2] in the bibliography.
6.3.5.3 Construction stage
As in EN 15804:2012+A2:2019, in addition:
The construction process stage includes information modules A4 and A5:
For module A4, assumptions regarding transport modes and distances shall be documented.
Module A5 includes manufacture and transportation of materials and any energy demand, e.g. for plaster
mixing or fixing of plasterboards using screw drivers, or water required for the installation or operation
at the construction site, e.g. water used for binders.
Module A5 includes also the estimation of installation waste generated on the jobsite. The default value
for jobsite gypsum-based waste shall be 5 % of the declared value, if not justified by exemption. Other
levels of jobsite waste shall be justified.
Module A5 includes further the treatment of the packaging materials of the declared product. Impacts for
disposal or other types of waste treatment have to be declared in module A5 whereas benefits, e.g. from
material recycling or exported energy from waste incineration are acco
