— are physically integrated with other products during installation so they cannot be physically
separated from them at end of life, and
— are no longer identifiable at end of life as a result of a physical or chemical transformation process.
If modules C1 to C4 and module D are not declared this decision shall be justified.
Construction products and materials that are identified as exceptions may omit the declaration of
modules C1-C4 and module D. Any omission of modules C1–C4 and module D shall be justified.
Types of EPD that may be provided are (see Figure 1):
— Cradle to gate with modules C1–C4 and module D: (A1-A3, C and D). These stages are the minimum
to be declared by for products as defined above and shall be based on a functional unit or declared
unit.
— Cradle to gate with options, modules C1–C4, and module D: (A1-A3, C, D and additional modules.
The additional modules may be A4 and/or A5 and/or B1-B7). This type of EPD is only possible for
products as defined above and shall be based on a functional unit or declared unit.
— Cradle to Grave with module D: (A, B, C and D). This declaration is only possible for products as
defined above and shall be based on a functional unit or declared unit.
— Cradle to gate: (A1-A3): These stages are the minimum to be declared for all construction products
that are exceptions as defined above and shall be based on a declared unit. Such an EPD covers raw
material supply, transport, manufacturing and associated processes, i.e. the product stage.
— Cradle to gate with options (A1-A3 and additional modules. The additional modules may be A4 and
A5): This type of EPD is only possible for construction products that are exceptions as defined
above and shall be based on a declared unit. These types of product cannot declare modules B1–B7.
NOTE 1 Information modules can supply information for processes for which there is no EPD available, e.g. a
cleaning process.
NOTE 2 An information module may contain: the values of the pre-determined indicators and the technical
information underlying their quantification, relevant technical information for further calculation of the
environmental performance, scenarios for further calculation of the environmental performance.
NOTE 3 It is possible to have an EPD for a substance or preparation (e.g. cement), for a product (e.g. window), for
a construction service (e.g. cleaning service as part of maintenance) and for an assemblage of products and/or a
construction element (e.g. wall) or technical equipment (e.g. lift).

taken into account;
— the elementary flows related to material inherent properties, such as biogenic carbon content, the
potential to carbonate or the net calorific value of a material, are considered completely and
consistently and the influence of the product systems on the operational aspects and impacts of the
building are taken into account.

“
5.4 Additional environmental information
5.4.1 General
Any additional environmental information provided shall meet the requirements in
EN ISO 14025:2010, 7.2.4, 7.2.5, 7.2.6 and 7.2.7.
In this core PCR the following categories of additional information are addressed:
5.4.2 Additional impact indicators
This core PCR includes additional environmental impact indicators. In order to acquire experience
about the calculation rules of such indicators a defined set of these LCA based additional environmental
impact indicators (see 7.2.3.2) shall be documented and explained in the project report. They may be
declared in the EPD and if declared they shall be declared as additional environmental impact
indicators including disclaimers (see 7.2.3.3). If any of these indicators are not declared in the EPD, a
justification shall be given in the EPD.
A complementary PCR (c-PCR) can define whether any additional environmental impact indicators shall
be declared in the EPD.
5.4.3 Additional information on carbon offset, carbon storage and delayed emissions
Carbon offset processes are not part of the product system under study. Carbon offset shall not be
included in the calculation of the GWP. Carbon offset information may be declared as additional
information. Such information shall be declared together with a description of calculation methodology
and sources.
NOTE A carbon offset is a reduction in emissions of carbon dioxide or other greenhouse gases made in order to
compensate for an emission elsewhere.
The effect of temporary carbon storage and delayed emissions, i.e. the discounting of emissions and
removals over a defined timeframe of up to 100 years, shall not be included in the calculation of the
GWP. The effect of permanent biogenic carbon storage shall also not be included in the calculation of
the GWP. However, the effect of carbon storage and delayed emissions may be declared as additional
information for GWP. Such information shall be declared together with a description of calculation
methodology and sources.

5.4.4 Additional Information not derived from LCA
In the core PCR the following two categories of information not derived from LCA shall be addressed:
— Additional technical information, describing technical conditions underlying scenarios and
characterizing the product’s technical and functional performance during the life cycle stages other
than the product stage and for the information provided under module D “benefits and loads
beyond the system boundary” for any scenario based calculations of the LCA based indicators
(see 6.3.9 and 7.3).
— Additional information on emissions to indoor air, soil and water during the use stage, describing
release of dangerous substances into indoor air, soil and water which are not covered by LCIA. This
additional information is required (see 7.4).
NOTE Information concerning health related emissions to indoor air, soil and water supports the social
performance of buildings which is addressed in EN 16309, Sustainability of construction works — Assessment of
social performance of buildings — Calculation methodology.
“.
10 Modification to 6.2.1 “General”
Replace the 1st paragraph with the following one:
“The environmental information of an EPD covering all life cycle stages (“cradle to grave”) shall be
subdivided into the information module groups A1-A3, A4-A5, B1-B5, B6-B7, C1-C4 and module D. Only
the declaration of the modules, A1-A3, C1-C4 and D is required for compliance with this standard
(see 5.2 for exceptions). The declaration of modules A4-A5, B1-B7 is optional.”.
11 Addition of 6.3.1 “Functional or declared unit”
Add a new subclause 6.3.1 “Functional or declared unit” which reads as follows:
“
6.3.1 Functional or declared unit
A construction product may have a number of possible functions. Based on the goal and scope of an
EPD, the EPD may relate to a specific function and scenario using a functional unit or it may cover a
range of functionalities and scenarios using a declared unit.
Both the functional unit and declared unit provide a reference by means of which the material flows
(input and output data) for each information module of a construction product are normalized (in a
mathematical sense) to produce data, expressed on a common basis. The functional or declared unit
provides the reference for combining material flows attributed to the construction product and for the
addition of environmental impacts for the selected stages of the construction product’s life cycle at the
building level (see Figure 1 and 7.5 on aggregation). Therefore, any functional unit or declared unit shall
be clearly defined and measurable.
NOTE In this standard the term “addition” also means the calculation of environmental impacts of a building or
construction works (EN 15978) by summation of the quantified impacts per indicator and per module of the
construction products constituting the building (e.g. adding kg CO equivalents for bricks + mortar + wall
2
insulation+ concrete block + gypsum plaster, etc.). Limitations on the addition of indicator results across life cycle
stages and their modules are described in 7.5.”.
Change the numbering of the following clauses accordingly.

12 Modification to 6.3.2 “Functional unit”
Replace the whole content of 6.3.2 “Functional unit” (former 6.3.1) with the following:
“
6.3.2.1 General
The functional unit defines the way in which the identified functions or performance characteristics of
the product are quantified. The primary purpose of the functional unit in LCA studies according to
ISO 14044 is to provide a reference by which material flows of construction product’s LCA results and
any other information are normalized to produce data expressed on a common basis, which allows
comparison with other product systems which have been assessed to provide the same functional unit.
NOTE 1 Comparisons of construction products with the same functional unit follow the rules in 5.3.
The functional unit of a construction product shall specify:
— the application of a product or product groups covered by the functional unit;
— reference quantity for the functional unit when integrated in the construction works;
— the quantified key properties, for the functional use or quantified performance characteristics or
minimum performance of the construction product when integrated into a building, taking into
account the functional equivalent of the building;
— the minimum performance characteristics under defined conditions shall be fulfilled over the
defined time period of the functional unit;
— a specified period of time under reference in-use conditions considering the RSL. If the functional
unit uses a different time period than the RSL, the RSL shall be given as technical information in the
EPD (see 6.3.3);
— when developing c-PCR product TCs shall specify the performance characteristics and reference in-
use conditions to be included in any functional unit.
NOTE 2 Guidance on the development of a functional unit is given in EN ISO 14040:2006, 5.2.2.
NOTE 3 Guidance on describing in-use conditions is given in Product Standards and ISO 15686-1, -2, -7 and -8.
NOTE 4 If there are, e.g. no test methods product TCs can develop RSL in accordance with ISO 15686 or use
independent empirical evidence.
6.3.2.2 Performance in a functional unit
The future function of the product within the building or construction works is often uncertain, as the
full functionality of a product may not be required at the building level. It is therefore not easy to define
a complete functional unit, which needs to include information on the required functional performance
of the product within the building or construction works over the full life cycle.
Nevertheless, for a cradle to grave EPD with functional unit a default (typical) application and the key
functionalities shall be defined. These are normally required from the product or products in this
application and provide other functional information as additional technical information.
The declared technical performance shall be based on specifications for determination or calculation of
this performance given in the relevant European harmonized Technical Specification (hEN, EAD) if
available.

Replace the whole content of 6.3.4 “Reference service life (RSL)” (former 6.3.3) with the following:
“
6.3.4.1 General
RSL information to be declared in an EPD covering the use stage shall be provided by the manufacturer.
The RSL shall be specified under defined reference in-use conditions. The RSL shall refer to the declared
technical and functional performance of the product within construction works. The RSL shall be
established in accordance with any specific rules given in European product standards or, if not
available, a PCR, and shall take into account ISO 15686-1, -2, -7 and -8. Where European product
standards or a c-PCR provide guidance on deriving the RSL, such guidance shall have priority.
Information on the product’s RSL requires specification of compatible scenarios for the product stage,
construction process stage and use stage. RSL is dependent on the properties of the product and
reference in-use conditions. The RSL shall be declared together with the reference in-use conditions and
it shall be stated that the RSL applies for the reference in-use conditions only.
The reference in-use conditions for achieving the declared technical and functional performance and
the declared reference service life shall include the following, where relevant:
