Wood and wood-based products - Calculation of sequestration of atmospheric carbon dioxide
EN 16449:2014 provides a calculation method to quantify the amount of atmospheric carbon dioxide based on the biogenic carbon content of wood.
Holz- und Holzprodukte - Berechnung der Speicherung atmosphärischen Kohlenstoff-Dioxids
Die vorliegende Norm bietet ein einfaches Berechnungsverfahren zum Abschätzen der Menge des durch den wachsenden Baum sequestrierten Kohlenstoff-Dioxids, welches dann bis zum Lebensende als biogener Koh-lenstoff in Holzprodukten gespeichert wird.
Bois et dérivés du bois - Calcul de la séquestration du dioxyde de carbone atmosphérique
La présente norme présente une méthode de calcul simple permettant d'estimer la quantité de dioxyde de carbone séquestrée par les arbres au cours de leur croissance puis stockée sous forme de carbone biogénique dans les produits du bois tout au long du cycle de vie de ces derniers.
Les in lesni izdelki - Izračun vezave atmosferskega ogljikovega dioksida
Standard EN 16449:2014 določa metodo za izračun količine atmosferskega ogljikovega dioksida na osnovi vsebnosti biogenega ogljika v lesu.

EN 16449:2014 (E) 4 Introduction By the process of photosynthesis, growing trees absorb (sequester) atmospheric carbon dioxide which is then, together with the release of some of the oxygen back into the atmosphere, incorporated, within the cambium, into the cells of the tree as both wood and bark. The absorbed carbon dioxide is effectively fixed in the wood as biogenic carbon. When using wood, that biogenic carbon is transferred to the product system. Wood products therefore constitute a pool (reservoir) of biogenic carbon for the duration of their service lifetime as those products. At end-
