A recent analysis by the Potsdam Institute for Climate Impact Research suggested that housing a growing population in dwellings constructed of wood rather than standard steel and concrete might save more than 100 billion tons of CO2 emissions until 2100. …In addition to harvesting from natural forests, freshly created timber plantations are needed to supply building wood. …scientists warned that if not carefully controlled, biodiversity may suffer. The study is the first to examine the effects of a large-scale transition to wood cities on land use, emissions from land-use change, and long-term carbon storage in harvested forests. …The scientists examined four distinct land-use scenarios: one with typical building materials like cement and steel, three with additional timber demand and how the additional high demand for wooden building materials could be met, where it would come from, and what the implications might be in terms of direct and indirect carbon emissions from land usage.
