Through the Build It With Wood initiative, New England Forestry Foundation (NEFF) helps speed the adoption of innovative, sustainable and long-lived wood products in construction, and also documents, researches and provides information about their climate benefits.


Just as the climate crisis demands we transition to renewable energy sources, so too do we need to transition to renewable materials. Wood was one of the earliest renewable materials adopted by human civilization, and remains important today.

New wood construction techniques, paired with new approaches to sustainable forest management, now enable a powerful opportunity to prevent damaging climate change, create a sustainable society, build rural economic opportunity in New England, and improve housing quality and equity. We invite you to learn more about these new mass timber construction techniques and their climate benefits on this resource-rich website.

Want to join us in protecting the region’s climate and building a local, sustainable bioeconomy? First, sign up for NEFF’s Forest-to-Cities Climate Challenge—a movement to help New England build a sustainable future with wood—and then do a deep dive into the world of sustainable wood construction on NEFF’s Build It With Wood website.
