Round and sawn timber - Environmental Product Declarations - Product category rules for wood and wood-based products for use in construction
This European Standard provides general Product Category Rules (PCR) for Type III environmental declarations for wood and wood-based products for use in construction and related construction and in-service processes.
This European Standard complements the core rules for the product category of construction products as defined in EN 15804 and is intended to be used in conjunction with EN 15804.
NOTE The assessment of social and economic performances at product level is not covered by this standard.
The core PCR:
— define the parameters to be declared and the way in which they are collated and reported;
— describe 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;
— define rules for the development of scenarios;
— include 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;
— include 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;
— define 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.
Additionally to the common parts of EN 15804, this European Standard for wood and wood-based products:
— defines the system boundaries;
— defines the rules for modelling and assessment of material-specific characteristics such as carbon storage and energy content of wood;
— defines allocation procedures for multi-output processes along the wood chain;
— defines allocation procedures for reuse, recycling and energy recovery;
— includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the assessment of carbon and energy content of wood;
— provides guidance/specific rules for the determination of the Reference Service Life (RSL).
This European Standard is intended to be used for cradle to gate or cradle to grave assessment, provided the intention is properly stated in the system boundary description.

— Proposal for co-product allocation (6.4.3.2);
— Add of new chapter Additional environmental information (7.6);
— Add of two informative annexes.
Introduction
EN 15804 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 harmonized way.
This document provides rules for Environmental Product Declarations (EPD) specifically for wood and
wood-based products. It complements the core product category rules for all construction products and
services as established in EN 15804.
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 EN 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 wood and wood-based products in order to minimize intra-
sectoral deviations.
EPD information is expressed in information modules as defined in EN 15804, which allow easy
organization and expression of data packages throughout the life cycle of wood and wood-based products.
The approach requires that the underlying data should be consistent, reproducible and comparable.
In line with EN 15804, the EPD is expressed in a form that allows aggregation (addition) to provide
complete information for buildings and other construction works. This document does not deal with
aggregation at the building level nor does this standard describe the rules for applying EPD in a building
assessment.
The document deals with a limited number of quantifiable parameters as predefined in EN 15804. Future
revisions of EN 15804 may lead to the incorporation of additional predetermined parameters.
This document provides the means for developing a Type III environmental declaration of wood and wood-
based construction products 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 method
EN 15804:2012+A2:2019, Sustainability of construction works — Environmental product declarations —
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
