Round and sawn timber - Environmental Product Declarations - Product category rules for wood and wood-based products for use in construction

EN 16485 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. 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.

EN 16485:2014 (E) 5 Introduction European Standard 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 European Standard 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 minimise vertical (branch specific) deviations. All common issues are covered horizontally for all wood and wood-based products in order to minimise 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. 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. Future revisions of EN 15804 may lead to the incorporation of additional predetermined parameters. This European Standard 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 15643-1, Sustainability of construction works — Sustainability assessment of buildings — Part 1: General framework — EN 15643-2, Sustainability of construction works — Assessment of buildings — Part 2: Framework for the assessment of environmental performance — EN 15978, Sustainability of construction works — Assessment of environmental performance of buildings — Calculation method — EN 15804, 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 — EN 15942, Sustainability of construction works — Environmental product declarations — Communication format business to business SIST EN 16485:2014

EN 16485:2014 (E) 6 1 Scope 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. SIST EN 16485:2014

EN 16485:2014 (E) 7 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 14025, Environmental labels and declarations — Type III environmental declarations — Principles and procedures (ISO 14025:2006) EN ISO 14044:2006, Environmental management — Life cycle assessment — Requirements and guidelines (ISO 14044:2006) EN 15804:2012, 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 15084:2012 and the following apply. 3.1 co-product any of two or more marketable materials, products or fuels from the same unit process, but which is not the object of the assessment Note 1 to entry: Co-product, by-product and product have the same status and are used for identification of several distinguished flows of products from the same unit process. From co-product, by-product and product, waste is the only output to be distinguished as a non-product. [SOURCE: EN 15804:2012, 3.7] Note 2 to entry: When further used as a material or fuel, according to COM (2007)59, (Communication from the Commission to the Council and the European Parliament on the Interpretative Communication on waste and by-products) Annex I, sawdust, wood chips and off-cuts from untreated wood as generated at saw mills or at secondary operation such as the manufacturing of furniture or pallets and packaging and customarily referred to as by-products are, for the purpose of this document, considered co-products. Materials of this type fall outside the definition of waste. However, where material of this kind requires a full recycling or recovery operation, or contains contaminants that need to be removed before it can be further used or processed, this would indicate that the material is a waste until the recycling or recovery operation is completed. 3.2 biogenic carbon carbon derived from/contained in biomass 3.3 biomass material of biological origin excluding material embedded in geological formations and material transformed to fossilised material 3.4 biogenic carbon neutrality balance of biogenic carbon uptake during growth of biomass and release during natural decay or incineration 3.5 carbon storage biogenic carbon stored over a specific period of time SIST EN 16485:2014

General aspects 5.1 Objective of this general PCR for wood and wood-based construction products An EPD according to this standard provides quantified environmental information for wood and wood-based construction product or related service on a harmonized and scientific basis. It also provides information on health related emissions to indoor air, soil and water during the use stage of the building. The purpose of an EPD in the construction sector is to provide the basis for assessing buildings and other construction works and identifying those which cause less stress to the environment. Thus the objective of this general PCR for wood and wood-based products is to ensure: — the provision of verifiable and consistent data for an EPD, based on LCA; SIST EN 16485:2014

EN 16485:2014 (E) 9 — the provision of verifiable and consistent product related technical data or scenarios for the assessment of the environmental performance of buildings; — the provision of verifiable and consistent product related technical data or scenarios potentially related to the health of users for the assessment of the performance of buildings; — that comparisons between construction products are carried out in the context of their application in the building; — the communication of the environmental information of construction products from business to business; — the basis, subject to additional requirements, for the communication of the environmental information of construction products to consumers. Declarations based on this standard are not comparative assertions. NOTE See definition 3.4 of EN 15804:2012 and EN ISO 14044:2006, 5.1 for more information concerning LCA used for comparative assertion. 5.2 Types of EPD with respect to life cycle stages covered As in EN 15804. 5.3 Comparability of EPD for construction products As in EN 15804. 5.4 Additional information As in EN 15804. 5.5 Ownership, responsibility and liability for the EPD As in EN 15804. 5.6 Communication formats As in EN 15804. 6 Product Category Rules for LCA 6.1 Product category The product category referred to in this standard includes all wood and wood-based construction products as well as related construction services for buildings and other construction works. 6.2 Life cycle stages and their information modules to be included 6.2.1 General As in EN 15804.

Values for apparent density and moisture content can be taken from product or application standards and should reflect the respective values underlying the LCA calculations. 6.3.2 Declared unit As in EN 15804 with the following addition: The declared unit is used instead of the functional unit when the precise function of the product or scenarios at the building level is not stated or is unknown. The declared unit shall be applied when an EPD covers one or more life cycle stages as information modules, i.e. in the case of a "cradle to gate" EPD and "cradle to gate with options" EPD and when the EPD is not based on a full “cradle to grave” LCA. The declared unit provides a reference by means of which the material flows of the information module of a construction product are normalised (in a mathematical sense) to produce data, expressed on a common basis. It provides the reference for combining material flows attributed to the construction product and for combining environmental impacts for the selected stages of the construction product’s incomplete life cycle (see 7.5). The declared unit shall relate to the typical applications of products. The declared unit in the EPD shall be one of the unit types listed below. A different unit may be declared for reasons that shall be explained and in such cases information shall be provided on how to convert this unit to one or more of the required unit types: — an item, an assemblage of items, e.g. 1 wood window; SIST EN 16485:2014

EN 16485:2014 (E) 11 — Volume (m3), e.g. 1 m3 of sawn timber; —

Mass (kg), e.g. wood chips, recovered wood; — Length (m), e.g. 1 m of wood moulding; — Area (m2), e.g. 1m2 of wall elements; 1 m2 of wood flooring; 1 m2 of wood-based panel. If the declared unit is not expressed in mass, then a conversion factor, e.g. to 1 kg of material shall be provided. For the development of, for example, transport and disposal scenarios, conversion factors to mass per declared unit shall be provided. For the development of, e.g. transport and disposal scenarios, the apparent density and moisture content shall be part of the declared unit provided. NOTE 1 Reasons for declaring units other than those listed include the need to use units normally used for design, planning, procurement and sale. NOTE 2 CEN Technical Committees for product standards are expected to harmonize the declared unit to be used for their product families. 6.3.3 Reference service life (RSL) (valid for cradle to gate with options and cradle to grave EPDs) As in EN 15804. 6.3.4 System boundaries 6.3.4.1 General As in EN 15804. 6.3.4.2 Product stage As in EN 15804 with the following addition: The product stage is an information module required to be included in the EPD. As illustrated in Figure 1 of EN 15804:2012 it includes the information modules A1 to A3. The system boundary with nature is set to include those technical processes that provide the material and energy inputs into the system and the following manufacturing, and transport processes up to the factory gate as well as the processing of any waste arising from those processes. NOTE 1 In accordance with European policies forests are understood as a natural system with multiple functions, the production function of timber being one of them. The existence of forests as natural systems is protected by European and national legislation. Therefore, natural growth and decay processes including natural disturbances etc. are not attributable to the production function of forests and are therefore - and as common practice - not considered in LCA. NOTE 2 Harvesting operations lead to temporal decreases in forest carbon pools in the respective stand. Impacts on forest carbon pools resulting from the sustainable or unsustainable management of forests, however, cannot be defined or assessed on stand level but requires the consideration of carbon pool changes on landscape level, i.e. the level based on which management decisions are made. Resulting from the fundamental principle of sustainable forest management to preserve the production function of forest, total forest carbon pools can be considered stable (or increasing) under sustainable forest management. This is due to the fact that temporal decreases of forest carbon pools resulting from harvesti
