Old-growth forests protected by strict conservation are conducive to both increasing carbon stock and biodiversity conservation. However, the carbon uptake will diminish and be zero as they reach the climax phase. Wood in construction and products stores carbon as well as avoids GHG emissions through substitution of more energy intensive materials such as concrete and steel. Studies show that, on average, the use of one cubic meter of wood in products or construction reduces about two tC02e of emissions (including the substitution effect). However, it is good to recognise that the climate benefits of wood use are highly case-specific and depend mainly on carbon-storage capacity of the product, its full life-cycle, as well as the properties of the material that has been substituted. Many countries have already taken national-level initiatives to promote the use of wood in construction.
