Introduction
This European standard provides core product category 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 harmonised way.
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 standardisation process has taken place in accordance with EN ISO 14025. All common issues are
covered horizontally for all product types in order to minimise vertical (branch specific) deviations.
EPD information is expressed in information modules, which allow easy organisation and expression of
data packages throughout the life cycle of the product. The approach requires that the underlying data
should be consistent, reproducible and comparable.
The EPD is expressed in a form that allows aggregation (addition) to provide complete #information
for buildings and other construction works$. This standard does not deal with aggregation at the
building level nor does this standard describe the rules for applying EPD in a building assessment.
#The standard deals with a set of quantifiable, predetermined environmental impact indicators. This
standard has been adapted to address the amendment of the standardization Mandate M/350.$
This European Standard provides the means for developing a Type III environmental declaration of
construction products and is part of a suite of standards that are intended to assess the sustainability of
construction works.

1 Scope
This European standard provides core product category rules (PCR) for Type III environmental
declarations for any construction product and construction service.
NOTE The assessment of social and economic performances at product level is not covered by this standard.
The core PCR:
— #defines the indicators to be declared, information to be provided and the way in which they are
collated and reported,$
— describes which stages of a product’s life cycle are considered in the EPD and which processes are
to be included in the life cycle stages,
— defines rules for the development of scenarios,
— includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment
underlying the EPD, including the specification of the data quality to be applied,
— includes the rules for reporting predetermined, environmental and health information, that is not
covered by LCA for a product, construction process and construction service where necessary,
— defines the conditions under which construction products can be compared based on the
information provided by EPD.
For the EPD of construction services the same rules and requirements apply as for the EPD of
construction products.
