Leather - Standard data for the calculation of leather density

This document specifies average values of leather density, depending on animal origin and thickness of finished leather, to be used for the calculation of LCA. This document is applicable to bovine, caprine and ovine types of leather.
This document does not apply to vegetable sole leather which is traded by weight.

Leder - Standardwerte für die Berechnung der Lederdichte

In diesem Dokument werden die Durchschnittswerte für die Lederdichte festgelegt, in Abhängigkeit von der Herkunft des Tieres und der Dicke des fertigen Leders, die für die Berechnung der Ökobilanz verwendet werden. Dieses Dokument ist auf Rinder , Ziegen  und Schafsleder anwendbar.
Dieses Dokument ist nicht auf pflanzliches Sohlenleder anwendbar, das nach Masse gehandelt wird.

Cuir - Données normalisées pour le calcul de la masse volumique du cuir

Le présent document spécifie les valeurs moyennes de la masse volumique du cuir, en fonction de l'origine animale et de l'épaisseur du cuir fini, à utiliser pour le calcul de l'ACV. Le présent document est applicable aux types de cuirs bovin, caprin et ovin.
Le présent document n‘est pas applicable au cuir de semelle végétal, qui est commercialisé sur la base du poids.

Environmental footprints of materials and products are getting increasing momentum in our
economies. Leather has been very active in this context; the tanning industry has developed both a CEN
Standard for calculating leather Carbon Footprint and leather Product Category Rules (PEFCR) in the
European context.
Whilst leather (except sole leather) is traded on the basis of m , LCA applications need to insert data on
material inputs in kg, so it is necessary to provide leather suppliers and customers with an instrument
that allows them to eco-design their leather products correctly.
