"Urbanization and population growth will create a vast demand for the construction of new housing and commercial buildings -- hence the production of cement and steel will remain a major source of greenhouse gas emissions unless appropriately addressed," says the study's lead-author Galina Churkina who is affiliated to both the Yale School of Forestry and Environmental Studies in the US and the Potsdam Institute for Climate Impact Research in Germany (PIK). "Yet, this risk for the global climate system could be transformed into a powerful means to mitigate climate change by substantially increasing the use of engineered timber for construction worldwide. Our analysis reveals, that this potential can be realized under two conditions. First, the harvested forests are sustainably managed. Second, wood from demolished timber buildings is preserved on land in various forms."
