Introduction These product category rules (PCR) are intended for companies preparing an Environmental

Product Declaration (EPD) for steel as construction material. The purpose of this document is to

define clear guidelines for performing the underlying life cycle assessment (LCA) to ensure

comparability between EPDs.

The PCR is based on and represent a supplement to the European standard EN 15804:2012 -

Sustainability of construction works – Environmental Product Declarations – core rules for the

product category of construction products. The PCR complies with the ISO standards, ISO

21930:2007 - Building construction - Sustainability in building construction – Environmental

declaration of building products and the requirements of ISO 14025:2006 - Environmental

labelling and declarations – Type III environmental declarations – Principles and procedures

and the provisions in ISO 14044:2006 - Environmental management — Life cycle assessment —

Requirements and guidelines.

The EPDs based on this PCR-document are covering two perspectives:

EPD – cradle to gate

EPD – cradle to grave including beyond life cycle of building and will present data that has been aggregated over the relevant life cycle stages as described in

chapter 6 and shown in figure 2.

shall be followed for the execution of inputs and outputs:

- all inputs and outputs to a (unit) process shall be included in the calculation, for which

generic data. Any assumptions for such choices shall be documented.

- In case of insufficient data or data gaps for a unit proves, the cut-off criteria shall be 1 %

of renewable and non-renewable primary energy usage and 1 % of the total mass input of

that unit process. The total of neglected input flows per module (A1-A3, etc.) shall be the

maximum of 5 % of energy usage and mass

- Particular care should be taken to include material and energy flows known to have the

potential to cause significant emission into air and water or soil related to the

environmental indicators

Selection of data 6.3.6

The application of generic and specific data shall follow the model in Table 1. Specific data

derived from the production process shall be used. Generic data can be used for processes the

manufacturer cannot influence, i.e. up- and downstream processes.

2 Economic value

Flows leaving the system and that are at the end-of-waste boundary of the products stage (A1-

A3), should be allocated as co-products by physical properties or by economic value when the

unit price difference is larger than 25%.

For the calculation of module D, a justified value-correction factor should be used to reflect the

functional equivalence of a product substituting primary raw materials.

the European Commission shall be used.

Parameters shall be declared and reported according to standard EN 15804: 2012, clause 7.2.2.

Environmental impact shall be declared as stated in EN 15804: 2012, clause 7.2.3, table 3:

Global warming potential, GWP, in kg CO2 equivalents, 100 years.

Depletion potential of the stratospheric ozone layer, ODP, in kg CFC 11 equivalents, 20 years.

Acidification potential of land and water sources, AP, in kg SO2 equivalents.

Eutrophication potential, EP in kg PO4 equivalents.

Formation potential of tropospheric ozone photochemical oxidants, POCP, in kg C2H4

equivalents.

Abiotic depletion potential for non-fossil fuels in Sb equivalents.1

The indicator describing the depletion of abiotic resources is subject to further scientific development. The use of

this indicator is intended to be reviewed during the revision of the Standard EN 15804: 2012.

measurements of release of regulated dangerous substances. Until the horizontal standards are


page 21 of 24

available, the EPD does not need to include this information, but the emissions should be

declared according to national standards and practices.

leaching, shall be given. Releases to ground and surface water during the use of the steel

supporting the verification of an EPD. The project report shall record that the LCA based

information and the additional information as declared in the EPD meet the requirements of EN

15804. It shall be made available to the verifier with the requirements on confidentiality stated in
