What We Do

We sequester CO₂ by durably preserving wood waste.

Trees capture CO₂ efficiently, but they emit CO₂ when they die and decay. We can sequester that carbon for millennia by preserving dry wood.

Why store wood?

• Dry wood resists decay

• Dry wood is 50% carbon, sequestering more than its weight in CO₂

• Wood waste is abundant (>1 Gigaton CO2e/year)
