In many parts of the world, wood was the go-to material for housebuilding for thousands of years, until it was supplanted by concrete and steel in the 20th century. Now, however, wood is making a comeback in the construction sector, with mass timber an increasingly popular alternative to more carbon-intensive materials. Gwen Busby, head of research and strategy at Nuveen Natural Capital, tells us that the growing market for mass timber has the potential to significantly increase demand for timber. The climate benefits of mass timber, she says, is a major factor in drawing climate-conscious investors toward including sustainably managed timberland in their portfolios.
