Flow chart of the wood and trade balance of Germany 2014 in million in m³(r) (roundwood equivalent)
On the supply side, our wood balances comprise the logged roundwood volume, the quantity of domestic recovered paper and recovered wood and the imports. The use side shows the exports and domestic consumption. Changes in stocks of wood products are also recorded. Data sources are official statistics, statistics from industry federations and scientific studies. Data of annual fellings are taken from Thünen-Recalculation of Wood Fellings, beginning with the year 1995. The general time series of our data start in 1950.
Wood and wood based products comprises all wood based raw materials as well as semi-finished and finished products.
For the calculation we use the unit cubic meters of roundwood equivalent (m³(r)). This unit is a theoretical figure which expresses how many units of roundwood have been used for the manufacturing of a unit of a specific wood based product. Consequently, losses of wood during processing are considered.
