The building sector is responsible for 44.6 percent of U.S. carbon dioxide (CO2) emissions. …many environmental experts, architects, and scientists are looking to mass-built timber as a reliable way to reduce carbon and fossil fuel output. …However, thanks in part to innovative wood products, including CLT, nail laminated timber (NLT), and glue laminated timber (glulam), wood construction can be used in buildings as tall as 40 stories. A study by … Poyry and the New England Forestry Foundation shows that the greatest potential for timber-built is in mid-rise (six to 14 story) buildings, as it also tends to be more economical to build with timber at that scale.
