EN 16887:2017 (E) 5 Introduction In order to satisfy market expectations, the Product Carbon Footprint (PCF) referred to a defined product needs to be prepared in compliance with specific methods and precise requirements, in order to allow a correct comparison among similar products. This aim can be achieved only if rules of calculation are defined, so that every organization can follow them in preparing a PCF for a specific product. These rules are called “product category rules” (or PCR), that are a complementary part of most general PCF programmes, but are fundamental both during the phase of LCA (Life Cycle Assessment) studies evaluation and the related declarations. As PCRs are internationally recognized, it is crucial that they are defined in a document discussed, shared and approved in an official international context as CEN is, and that they are included in a standard. In this way they will be applied by the organizations in all interested countries. SIST EN 16887:2017



EN 16887:2017 (E) 6 1 Scope This European Standard provides a system for calculation of the carbon footprint of leather as defined in EN 15987 and sold in the semi-processed state or ready to be shipped for use in consumer articles manufacturing processes. 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 15987:2015, Leather — Terminology — Key definitions for the leather trade EN ISO 2589, Leather — Physical and mechanical tests — Determination of thickness (ISO 2589) EN ISO 14021:2016, Environmental labels and declarations — Self-declared environmental claims (Type II environmental labelling) (ISO 14021:2016) EN ISO 14025, Environmental labels and declarations — Type III environmental declarations — Principles and procedures (ISO 14025) CEN ISO/TS 14067, Greenhouse gases — Carbon footprint of products — Requirements and guidelines for quantification and communication (ISO/TS 14067) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 15987 and CEN ISO/TS 14067 and the following apply. 3.1 leather hide or skin with its original fibrous structure more or less intact, tanned to be imputrescible, where the hair or wool may or may not have been removed, whether or not the hide or skin has been split into layers or segmented either before or after tanning and where any surface coating or surface layer, however applied, is not thicker than 0,15 mm Note 1 to entry: If the tanned hide or skin is disintegrated mechanically and/or chemically into fibrous particles, small pieces or powders and then, with or without the combination of a binding agent, is made into sheets or other forms, such sheets or forms are not leather. Note 2 to entry: If the grain layer has been completely removed, the term leather will not be used without further qualification, e.g. split leather, suede leather. [SOURCE: EN 15987:2015, 4.1.1, modified — Note 2 to entry was slightly modified] 3.2 sole leather, vegetable tanned leather tanned with vegetable tannins and finished for the outsoles of footwear 3.3 crust leather which is tanned, fatliquored and dried, before finishing [SOURCE: EN 15987:2015, 4.1.3] SIST EN 16887:2017



EN 16887:2017 (E) 7 3.4 split leather layer from a hide or skin made from a flesh split or a middle split, without any grain structure, tanned to be imputrescible Note 1 to entry: A split is a layer of hide or skin obtained by dividing it horizontally (splitting) to obtain at least two separate layers; the top layer is called grain split, and the bottom layer is called flesh split; for heavy hides also a middle split can be obtained. Note 2 to entry: If the name of the animal whence it originates, or the part of the animal whence it comes, is included in the description, the term “split leather” will be used as a noun, e.g. pig split leather. [SOURCE: EN 15987:2015, 4.1.2] 3.5 fleshings small pieces of connective and adipose tissues cut from the inner surface of hides and skins in the fleshing operation 3.6 by-product substance or object resulting from a production process, the primary aim of which is not the production of that item Note 1 to entry: By-product is a production residue that is not waste. 3.7 Product Category Rules PCR documents that define requirements that are compulsory for the environmental declarations of a certain category of products according to EN ISO 14025 and that enable transparency and comparability between different
environmental footprint studies of these products of a same category 3.8 semi-processed leather intermediates of leather production, like wet blue, wet-white, crust, pickled pelt, etc 3.9 upstream process process occurring along the supply chain of purchased goods/services prior to entering the core process 3.10 product system (core process) collection of unit processes with elementary and product flows, performing one or more defined functions, and which models the life cycle of a product [SOURCE: EN ISO 14040:2006, 3.28] 3.11 downstream process process occurring along a product supply chain after entering the core process SIST EN 16887:2017



EN 16887:2017 (E) 8 3.12 primary data quantified value of a unit process or an activity obtained from a direct measurement or a calculation based on direct measurements at its original source Note1 to entry: Primary data need not necessarily originate from the product system under study because primary data relate to a different but comparable product system to that being studied. Note 2 to entry: Primary data include Green House Gases (GHG) emission factors and/or GHG activity data (defined in EN ISO 14064-1:2012, 2.11). 3.13 site-specific data data obtained from a direct measurement or a calculation based on direct measurement at its original source within the product system Note 1 to entry: All site-specific data are primary data but not all primary data are site-specific data because they also relate to a different product system. 3.14 secondary data data obtained from sources other than a direct measurement or a calculation based on direct measurements at the original source Note 1 to entry: Such sources include databases and published literature validated by stakeholders. 3.15 product result of activities or processes; a product can be tangible or intangible, or a combination of both Note 1 to entry: The product is categorized as follows: — services (e.g. transport, subcontractors activity); — processed materials (e.g. hides). Note 2 to entry: Services have tangible and intangible elements. Provision of a service involves, for example, the following: — an activity performed on a customer-supplied tangible product (e.g. hide to be fleshed). Processed materials are generally tangible and their amount is a continuous characteristic. Note 3 to entry: Adapted from EN ISO 14021:2016 and EN ISO 9000:2015. 3.16 chemicals substance or mixture of substances having a constant chemical composition and characteristic properties SIST EN 16887:2017



EN 16887:2017 (E) 9 4 PCR elements 4.1 General The following subclauses define the data to be collected for each PCR item, in order to prepare a leather Product Carbon Footprint (PCF). 4.2 Definition of the product group 4.2.1 General The product group includes all kind of leather as defined in 3.1, from animals bred for purposes different from leather production (e.g. meat, milk, etc.). This PCF is applicable to any intended use, that shall be specified. Articles with the same functional unit shall be grouped in categories characterized by a similar intended use, as appropriate. 4.2.2 Identification of manufacturing company The information about the manufacturing/producing company to be included in a leather PCF shall be at least: — company name; — tannery production site(s) included in the system boundary; — issuer and contacts; — specification of the process phases carried out in the production site(s). Other voluntary information (e.g.): — information on environmental management system; — specific aspects regarding production; — environmental policy; — manufacturers logotype. 4.2.3 Specification of the product The product under consideration in this standard is “Leather” (3.1), intended as a semi-processed or finished product to either be further processed in the tanning sector or, after completion of all processing steps, in various consumer articles’ manufacturing sectors. SIST EN 16887:2017



EN 16887:2017 (E) 10 Finished or semi-processed leather shall be characterized through the minimum elements included in Table 1: Table 1 — Elements for product specification Product characteristic Example Animal type Bovine Leather type Full grain, flesh split, grain split etc. Thickness ranges (EN ISO 2589) 0,9 – 1,1 mm Process stage Wet blue/crust/finished Type of tanning Synthetic or vegetable or other kind of tanning Intended use(s) Footwear, leather goods etc. If different ranges of thickness are used, all of them shall be reported. To fill in the table, the EN 15987 terms shall be used for describing “leather type”, “process stage” and “type of tanning”. For semi-processed products, the intended use shall be leather. 4.3 Functional unit The functional unit shall be 1 m2 of leather. For the particular case of sole leather (3.2), the functional unit is 1 kg. NOTE It is however usual that semi-finished products are measured in kilograms till they are transformed in crust; only after the subsequent processing the measuring unit usually passes to squared meters. LCI (Life Cycle Inventory) study specifies where this passage occurs relatively to the different process phases. 4.4 Bill of materials The finished leather is composed by stabilized collagen and chemical residuals. Depending on the type of tanning carried out during the process the percentage of the total weight of collagen can vary from 50 % (vegetable sole leather) up to 85 % (chrome tanned leather). The chemicals used during the process can be considered in two main families: those whose intended function is to treat the substrate but do not remain in the finished leather (example: surfactants, acids, bases, etc.) and those whose function is to remain inside the leather. For leather carbon footprint calculation all chemicals shall be included. The bill of materials shall include only t
