Introduction
How to use this document

This document provides product category rules (PCR) for Type III environmental declarations (EPDs)

according to !EN 15804:2012+A2:2019" for cement and building lime, in particular to products

according to the standards developed in CEN/TC 51 “Cement and building limes”.

The European Standard !EN 15804:2012+A2:2019", “Core rules for the product category of

construction products”, is intended as the core PCR to be followed. This PCR document supplements

!EN 15804:2012+A2:2019" by giving more detail for specific items relevant to cement and

building lime. In all cases where no specific rules are given in this document,

!EN 15804:2012+A2:2019" should be followed. Therefore, this document should be read in

parallel with !EN 15804:2012+A2:2019". !EN 15804:2012+A2:2019" is normatively
referenced in this document and is indispensable for its application.

The structure of this document follows that of !EN 15804:2012+A2:2019", with all headings and

section numbers kept the same. Where a section of !EN 15804:2012+A2:2019" applies without

modification, this is indicated. Where a section of !EN 15804:2012+A2:2019" is not relevant for

EPDs covered by this PCR, this is also indicated.
The purpose of an EPD is given in the Introduction to !EN 15804:2012+A2:2019".
Definition of the covered products
Cement

Cement is defined in standards published by CEN/TC 51 as “a hydraulic binder, i.e. a finely ground

inorganic material which, when mixed with water, forms a paste which sets and hardens by means of

hydration reactions and processes and which, after hardening, retains its strength and stability even

under water”.
Building Lime

Building lime is defined in EN 459-1 as a “group of lime products, exclusively consisting of two families:

air lime and lime with hydraulic properties, used in applications or materials for construction, building

and civil engineering.” Air lime refers to the product which combines and hardens with carbon dioxide

present in air.

Air lime refers to the product which combines and hardens with carbon dioxide present in air. Air lime

has no hydraulic properties. Air lime is divided into two sub-families, calcium lime (CL) and dolomitic

lime (DL). Calcium lime is an air lime consisting mainly of calcium oxide (quicklime) and/or calcium

hydroxide (hydrated lime). Dolomitic lime is an air lime consisting mainly of calcium magnesium oxide

and/or calcium magnesium hydroxide.

Lime with hydraulic properties is a building lime consisting mainly of calcium hydroxide, calcium

silicates and calcium aluminates. It has the property of setting and hardening when mixed with water

and/or under water. Reaction with atmospheric carbon dioxide is part of the hardening process. Lime

with hydraulic properties is divided into three subfamilies, natural hydraulic lime (NHL), formulated

lime (FL) and hydraulic lime (HL).

1 Scope

The general scope of the core product category rules (PCR) is given in !EN 15804:2012+A2:2019",

Clause 1.

This PCR is primarily intended for the creation of cradle-to-gate EPDs of cement and building lime.

In other respects, the scope is as in !EN 15804:2012+A2:2019".
2 Normative references

!The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

EN 15804:2012+A2:2019, Sustainability of construction works — Environmental product declarations —

Core rules for the product category of construction products"
3 Terms and definitions

For the purposes of this document, the terms and definitions given in !EN 15804:2012+A2:2019"

apply.
4 Abbreviations
As in !EN 15804:2012+A2:2019".
5 General aspects
5.1 Objective of the Core PCR
As in !EN 15804:2012+A2:2019".
5.2 Types of EPD with respect to life cycle stages covered
As in !EN 15804:2012+A2:2019".

!Cement and building lime are physically integrated with other products (e.g. aggregates, chemical

admixtures) into downstream products (e.g. concrete, mortar, plaster). During their hydration, cement

and building lime undergo a chemical transformation. After their hydration, the original products in the

un-hydrated state are not identifiable anymore and cannot be physically separated.

None of the constituents of cement and building lime contain biogenic carbon.
Cement and building lime therefore fulfil the three conditions:

— the product or material is physically integrated with other products during installation so they

cannot be physically separated from them at end of life, and

— the product or material is no longer identifiable at end of life as a result of a physical or chemical

transformation process, and

— the product or material does not contain biogenic carbon and are therefore exempt from the

obligation to declare modules C1–C4 and D."

SIST EN 16908:2017+A1:2022
EN 16908:2017+A1:2022 (E)

Cement and building lime are intermediate products with many different final uses. Cement may for

example be used in ready-mix concrete, precast concrete, mortar, screed, base treatment for various

types of infrastructures, etc. Building lime may for example be used in plasters, renders, masonry

mortars, calcium silica bricks, autoclave aerated concrete, soil treatment, asphalt mixtures etc.

Therefore, it is generally not possible to provide information about the environmental impacts of the

products during the construction process, use, and end of life stages, as this will greatly depend on how

the cement or building lime is used.

For this reason, this PCR is primarily intended to support the creation of cradle-to-gate EPDs, i.e. it

focuses on the life cycle stages A1 – A3: raw material supply, transport, and manufacturing, although

other stages may also be included.

Information on other life cycle modules may be provided in an EPD if relevant. Particularly information

on carbonation of building limes in the life cycle modules A5 and B1 may be provided in EPDs.

If additional stages are included, the modularity principle shall be observed (see 6.3.4.1 of

!EN 15804:2012+A2:2019") in order to produce consistent EPDs.
5.3 Comparability of EPD for construction products
As in !EN 15804:2012+A2:2019".

As cement and building lime are intermediate products, no functional unit can be defined in EPDs for

cement and building lime (see 6.3) and therefore no comparisons with other construction products can

be made based on EPDs according to this PCR. As stated in !EN 15804:2012+A2:2019", “EPD that

are not in a building context are not tools to compare construction products and construction services”.

5.4 !Additional environmental information
5.4.1 General
As in EN 15804:2012+A2:2019.
5.4.2 Additional impact indicators
As in EN 15804:2012+A2:2019.

In EPDs for cement and building lime, the impact categories “Particulate Matter emissions” and

“Ionizing radiation, human health” should be declared. The indicators “Eco-toxicity (freshwater)”,

“human toxicity, cancer effects”, “Human toxicity, non-cancer effects” and “Land use related

impacts/Soil quality” may be declared in EPDs for cement. However, the uncertainties with respect to

the results are high.

5.4.3 Additional information on carbon offset, carbon storage and delayed emissions

As in EN 15804:2012+A2:2019.
5.4.4 Additional Information not derived from LCA
As in EN 15804:2012+A2:2019.

For additional information on emissions to indoor air, soil and water during the use stage, please refer

to the respective PCR/EPDs for downstream products such as ready-mix concrete, precast concrete,

screed, plasters, masonry mortars, etc.
The life cycle of lime is shown in Figure 2."

6.3.2 !Functional unit
6.3.2.1 General
As in EN 15804:2012+A2:2019.

As cement and building lime are intermediate products, no functional unit can be defined in EPDs for

cement and building lime. A declared unit is used as defined in 6.3.3.

6.3.4 Reference service life (RSL)
6.3.4.1 !General
As in EN 15804:2012+A2:2019.

No RSL is declared for cement or building lime as they are intermediate building products. A reference

service life could be declared for downstream products such as ready-mix concrete, precast concrete,

screed, plasters, masonry mortars or other building products in which cement and/or building lime are

used.
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".

Biogenic CO emissions can be compensated by re-growth of biomass in the short term. Therefore, CO

2 2

emissions from biomass fuels (secondary fuels or waste) and the biogenic carbon content of mixed fuels

(secondary fuels or waste) shall not be included in the total CO emissions [10], [11].

For emissions from waste and secondary fuels see Annex D. As a conservative approach, if wastes are

used for energy or material recovery and do not have the same waste status in all regions, for

transparency reasons two figures may be specified in the communication of the LCA results in module

A1 to A3:

— the environmental impacts caused by the emissions including processing, incineration and co-

incineration of waste (gross figure); and

— the environmental impacts caused excluding the incineration of waste (net figure), see Annex D.

— Extraction of raw materials. This includes the quarrying of calcareous or dolomitic materials,

such as limestone or marl, siliceous materials such as sand, argillaceous material, such as clay

or shale and aluminous materials such as bauxite.

— Extraction of primary fuels. Major primary fuels used in the production of cement and building

lime are coal, petcoke, lignite and natural gas.
— A1 Production of upstream products

— Production of quicklime or hydrated lime and alumina for the production of calcium aluminate

cements.

— Production of cements or other pre-products (cf. Annex D of EN 459-1:2015) for the

production of building lime.
