“Wood can help to earn points in categories typically found in green building rating systems— including certified wood, recycled/reused/salvaged materials, local sourcing of materials, waste minimization,
indoor air quality, advanced building techniques and skills and life cycle impacts” …

Sustainability and wood
• Wood is the only major renewable building material
• Wood is recyclable and triggered biodegradable
• Wood products store carbon
• Life Cycle Assessment (LCA) studies show wood to have a comparatively small environmental footprint
• Wood creates a healthy indoor environment
Carbon sequestration and storage
• Wood and wood products store carbon until they burn or biodegrade
