The bipartisan 21st Century ROAD to Housing Act — the first major overhaul of housing legislation in more than 30 years — is good news. But the policy, which aims to accelerate housing production across the country, also sets in motion surging demand for one of the oldest and most consequential building materials on Earth: wood. …As cities grapple with the need to increase housing production and decarbonize the built environment, they must take seriously the ecological impact of these material demands. …Since the 1990s, many North American timber operations have received certifications from forestry-standard groups, signaling to eco-conscious developers, architects, and investors that their wood products were responsibly produced. The Forest Stewardship Council (FSC) and the Sustainable Forestry Initiative (SFI) cover the majority of operations in North America. …But SFI policies around clearing primary forests are vague, while the FSC Mix label allows a product to include a majority of wood from non-certified logging operations.
