Under the new law, French builders are required to use a certain portion of wood in the construction of new buildings. The required amount is proportionate to floor area and the minimum requirement varies according to the intended use of the building.
The largest wood use requirement is placed on residential buildings. The law also stipulates that the wood used in buildings has to be sourced from sustainably managed forests.
Similar thinking could well be applied in Finland, too. It would be possible to increase the use of wood in construction quite considerably, as the daily growth of the carbon reservoir of Finnish forests is equal to the construction sector’s annual wood consumption.
The structures of the average wooden Finnish single-family home bind about 30 tonnes of carbon dioxide. This is slightly more than the carbon dioxide emissions caused by the average consumer’s motoring in ten years.
The manufacture of wood-based construction materials produces very little carbon dioxide when compared to other materials. Unlike other construction materials, wood uses atmospheric carbon dioxide for its growth – and this carbon dioxide remains bound in wood-based products for their entire lifecycle.
