CLT Comes Up Short

Don’t be fooled by all the sustainability messaging you hear about cross-laminated timber (CLT). The wood industry claims that CLT is better for the environment than precast concrete.  Proponents tout wood’s capacity to sequester carbon, but the reality is an eye opener: the wood industry is actually the largest sector contributing to carbon pollution.

To build an 18-story, 180,000 sq. ft. CLT building, you need lots of wood – over 17 acres of it. In the process, you’ll release 11,533 metric tons of carbon dioxide into the atmosphere. It’s one of the reasons why clear-cutting trees is behind 12% of the world’s gas emissions, more than all of the cars and trucks on earth. CLT isn’t a form of construction. It’s deforestation, pure and simple.
