Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements
This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This document applies to concrete and concrete elements for building and civil engineering, excluded autoclaved aerated concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete elements:
- defines the system boundaries;
- defines the modelling and assessment of material-specific characteristics;
- defines allocation procedures for multi-output processes along the production chain;
- defines allocation procedures for reuse and recycling;
- includes the rules for calculating the LCI and the LCIA underlying the EPD;
- provides guidance/specific rules for the determination of the reference service life (RSL);
- gives guidance on the establishment of default scenarios;
- gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

Dieses Dokument gilt für Betone und Betonelemente für Gebäude und für Ingenieurbauwerke, mit Ausnahme von Porenbeton.
Dieses Dokument legt die anzugebenden Parameter und darüber hinaus fest, welche EPD-Typen (und Phasen des Lebenszyklus) zu behandeln und welche Regeln zu befolgen sind, um Sachbilanzen (LCI) zu generieren und Wirkungsabschätzungen (LCIA) durchzuführen, und welche Qualität die bei der Erstellung von EPDs verwendeten Daten haben müssen.
Zusätzlich zu den allgemeinen Abschnitten von EN 15804:2012+A2:2019 hat dieses Dokument für Beton und Betonelemente folgende Ziele: Es
- legt die Systemgrenzen fest;
- legt die Modellierung und Beurteilung der materialspezifischen Eigenschaften fest;
- legt die Allokationsverfahren für Multi-Output-Prozesse entlang der Produktionskette fest;
- legt die Allokationsverfahren für die Wiederverwendung und das Recycling fest;
- enthält die Regeln für die Berechnung der Sachbilanz und der Wirkungsabschätzung, die der EPD zugrunde liegen;
- liefert eine Anleitung/spezielle Regeln für die Ermittlung der Referenz-Nutzungsdauer (RSL, en: reference service life);
- gibt eine Anleitung zur Festlegung von Standardszenarien;
- gibt eine Anleitung für übliche funktionale Einheiten für Betonelemente.
Dieses Dokument ist für die Anwendung bei der Beurteilung der Herstellungsphase sowie weiterer Phasen (von der Wiege bis zum Werkstor mit Optionen) oder der Beurteilung des gesamten Lebenszyklus (von der Wiege bis zur Bahre) vorgesehen; Voraussetzung dafür ist, dass die Ziele in der Beschreibung der Systemgrenzen vorschriftsmäßig angegeben sind.
Auf Bauwerksebene liefert eine umfassende Deklaration (von der Wiege bis zur Bahre) ein besseres Gesamtverständnis der Umweltfolgen, die sich aus Beton und Betonelementen ergeben.

Introduction
The European Standard EN 15804:2012+A2:2019 provides core rules for all construction products and
services.
It provides a structure to ensure that all Environmental Product Declarations (EPD) of construction
products, construction services and construction processes are derived, verified and presented in a
harmonized way.
This European Standard provides additional rules for Environmental Product Declarations (EPD)
specifically for concrete and concrete elements. It complements the core rules for all construction
products and services as established in EN 15804:2012+A2:2019.
An EPD communicates verifiable, accurate, non-misleading environmental information for products and
their applications, thereby supporting scientifically based, fair choices and stimulating the potential for
market-driven continuous environmental improvement.
The standardization process has taken place in accordance with ISO 14025. All common issues are
covered horizontally for all product types in order to minimize vertical (branch specific) deviations. All
common issues are covered horizontally for all concrete and concrete elements in order to minimize
intra-sectorial deviations.
EPD information is expressed in information modules as defined in EN 15804:2012+A2:2019, which
allow easy organization and expression of data packages throughout the life cycle of concrete and
concrete elements. The approach requires that the underlying data should be consistent, reproducible
and comparable.
In line with EN 15804:2012+A2:2019 the EPD is expressed in a form that allows aggregation (addition)
to provide complete information for buildings. This standard does not deal with aggregation at the
building level nor does this standard describe the rules for applying EPD in a building assessment.
The standard deals with a limited number of quantifiable parameters as predefined in
EN 15804:2012+A2:2019. Future revisions of EN 15804 may lead to the incorporation in this standard
of additional predetermined parameters. This European Standard provides the means for developing a
Type III environmental declaration of concrete and concrete elements in the context of the suite of
standards that are intended to assess the sustainability of construction works.
This suite of standards includes:
— EN 15643, Sustainability of construction works — Framework for assessment of buildings and civil
engineering works
— EN 15978, Sustainability of construction works — Assessment of environmental performance of
buildings — Calculation methods
— EN 15804:2012+A2:2019, Sustainability of construction works — Environmental product
declaration — Core rules for the product category of construction products
— CEN/TR 15941, Sustainability of construction works — Environmental product declarations —
Methodology for selection and use of generic data
— EN 15942, Sustainability of construction works — Environmental product declarations —
Communication format — Business to business
— CEN/TR 16970:2016, Sustainability of construction works — Guidance for the implementation of
EN 15804

1 Scope
This document complements the core rules for the product category of construction products as defined
in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This c-PCR applies to products within the scope of CEN/TC 104 and CEN/TC 229, but it may be applicable
to other concrete products until they have product specific c-PCRs.
This document applies to concrete and concrete elements for building and civil engineering, but excludes
autoclaved aerated concrete and resin bound concrete. Apart from Annex G, it may be used as guidance
for glass fibre reinforced concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be
covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle
Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete
elements:
— defines the system boundaries;
— defines the modelling and assessment of material-specific characteristics;
— defines allocation procedures for multi-output processes along the production chain;
— defines allocation procedures for reuse and recycling;
— includes the rules for calculating the LCI and the LCIA underlying the EPD;
— provides guidance/specific rules for the determination of the reference service life (RSL);
— gives guidance on the establishment of default scenarios;
— gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment,
provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive
understanding of the environmental impact associated with concrete and concrete elements.

Introduction
The European Standard EN 15804:2012+A2:2019 provides core rules for all construction products and
services.
It provides a structure to ensure that all Environmental Product Declarations (EPD) of construction
products, construction services and construction processes are derived, verified and presented in a
harmonized way.
This European Standard provides additional rules for Environmental Product Declarations (EPD)
specifically for concrete and concrete elements. It complements the core rules for all construction
products and services as established in EN 15804:2012+A2:2019.
An EPD communicates verifiable, accurate, non-misleading environmental information for products and
their applications, thereby supporting scientifically based, fair choices and stimulating the potential for
market-driven continuous environmental improvement.
The standardization process has taken place in accordance with ISO 14025. All common issues are
covered horizontally for all product types in order to minimize vertical (branch specific) deviations. All
common issues are covered horizontally for all concrete and concrete elements in order to minimize
intra-sectorial deviations.
EPD information is expressed in information modules as defined in EN 15804:2012+A2:2019, which
allow easy organization and expression of data packages throughout the life cycle of concrete and
concrete elements. The approach requires that the underlying data should be consistent, reproducible
and comparable.
In line with EN 15804:2012+A2:2019 the EPD is expressed in a form that allows aggregation (addition)
to provide complete information for buildings. This standard does not deal with aggregation at the
building level nor does this standard describe the rules for applying EPD in a building assessment.
The standard deals with a limited number of quantifiable parameters as predefined in
EN 15804:2012+A2:2019. Future revisions of EN 15804 may lead to the incorporation in this standard
of additional predetermined parameters. This European Standard provides the means for developing a
Type III environmental declaration of concrete and concrete elements in the context of the suite of
standards that are intended to assess the sustainability of construction works.
This suite of standards includes:
— EN 15643, Sustainability of construction works — Framework for assessment of buildings and civil
engineering works
— EN 15978, Sustainability of construction works — Assessment of environmental performance of
buildings — Calculation methods
— EN 15804:2012+A2:2019, Sustainability of construction works — Environmental product
declaration — Core rules for the product category of construction products
— CEN/TR 15941, Sustainability of construction works — Environmental product declarations —
Methodology for selection and use of generic data
— EN 15942, Sustainability of construction works — Environmental product declarations —
Communication format — business to business

1 Scope
This document complements the core rules for the product category of construction products as defined
in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This document applies to concrete and concrete elements for building and civil engineering, excluded
autoclaved aerated concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be
covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle
Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete
elements:
— defines the system boundaries;
— defines the modelling and assessment of material-specific characteristics;
— defines allocation procedures for multi-output processes along the production chain;
— defines allocation procedures for reuse and recycling;
— includes the rules for calculating the LCI and the LCIA underlying the EPD;
— provides guidance/specific rules for the determination of the reference service life (RSL);
— gives guidance on the establishment of default scenarios;
— gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment,
provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive
understanding of the environmental impact associated with concrete and concrete elements.

6.2 Life cycle stages and their information modules to be included
6.2.1 General
In addition to the text of EN 15804:2012+A2:2019:
As all life cycle stages (from A1 to C4 and D) shall be included when assessing a construction work
(building or civil engineering), it is recommended that EPDs prepared cover the same life cycle, i.e. cradle
to grave and module D.
A general description of the life cycle stages is given in Figure 1.
6.2.2 A1-A3, Product stage, information modules
In addition to the text of EN 15804:2012+A2:2019:
NOTE Concrete and concrete elements may contain the following constituents or products (not exhaustive
list):
— aggregates;
— cement;
— water;
— admixtures;
— additions;
— fibres;
— reinforcing steel (for precast concrete elements).
When the full LCI of constituents is not available, impact indicators and aspects from the EPDs complying
to EN 15804:2012+A2:2019 for the constituents or for ready-mixed concrete, covering modules A1 to A3,
can be used for the assessment of module A1 of the concrete or concrete element. If transport is included,
then the impacts and aspects covering modules A1 to A4 can be used for the assessment of modules A1
and A2 (see Figure 2).
