What does sustainable management mean in a DED?

Two types of DED are available for wood products (sustainable or non-sustainable management of the resource). The calculation method applies safety coefficients to all the processes that contribute to the global warming impact indicator, excluding those related to biogenic carbon where the real balance between capture and emission is kept as it is in the calculation, without application of a safety factor. In case of sustainably managed resources, capture of biogenic carbon dioxide is affected by a coefficient of -1, and emission of biogenic carbon dioxide and methane respectively by a coefficient + 1, and + 25, for the impact indicator on global warming. In case of resources that are not managed sustainably, no capture of biogenic carbon dioxide is considered. Emissions are considered in the same way. If the origin of the wood is not known, the DED considers unsustainable resource management.
