More wood construction for less climate change
Increasing the use of wood in construction is an efficient way to mitigate climate change. Houses built mainly of wood, which store carbon most efficiently, can have as much as 300 kilograms of carbon per floor square metre. 300 kg

If wood were used in the structures, cladding, surfaces and furnishings of new buildings, they could store 55 million tonnes of carbon dioxide in Europe annually. 55 million tonnes
Metsä Group aims to increase the volume of carbon sequestered in forests by 2030. Between 2010 and 2020, Metsä Group and Finnish forest owners planted 270 million seedlings. In 2021, the number will increase by a further 35 million seedlings. 270 million

harvested, it acts as a carbon sink, increasing the volume of carbon sequestered in the trees.
The volume of atmospheric carbon sequestered in Nordic softwood species accounts for some 50 per cent of the dry weight of the wood. Depending on the species, one cubic metre weighs 380–403 kilograms. 50 %

In Finland, approximately 80 per cent of the annual net growth of forests is harvested, which means that the wood volume in forests is increasing annually. In 2020, the volume of growing stock in Finland totalled some 2.5 billion cubic metres.
