This paper investigates whether the growing popularity of mass timber as a construction material could lead to unsustainable logging practices in the United States. The authors utilize U.S. Forest Service data to project future timber demand based on optimistic estimates of mass timber consumption in 2035 and compare this with current and projected forest growth. Their analysis considers various factors, including regional differences and timber growth in both harvestable and protected areas, aiming to determine if the U.S. timber supply can sustainably meet the anticipated increase in demand driven by mass timber adoption.
