Sucking up CO2
HQ: San Francisco, CA
Engineering faster-growing, more durable trees.
The Big Idea
Growing trees is the cheapest way to draw down CO2. Yet, far from planting new trees on net, the planet loses 25 million acres of forest each year to fire, agriculture, harvesting, and pests. As a result of other changes to the climate system, it also appears that forests’ capacity to retain carbon is decreasing. It’s no longer enough to plant new trees. We have to develop trees that grow taller, faster, stronger.
How it Works
Living Carbon uses genetic engineering to improve how trees break down a toxic byproduct of photosynthesis. They also dial up the assimilation of certain metals that heighten resistance to fungal decomposition. The result is carbon-guzzling photosynthesis-enhanced trees that grow 30-54% faster while producing more drought- and rot-resistant wood without the need for chemically-intensive treatments.
Living Carbon’s edge comes from seedlings grow more valuable wood products that can be harvested years earlier. Their growth rate shortens the path to profitability of timberland by 2-5 years, resulting in a 50% revenue increase over a 20 year period. In the process, they double the CO2 uptake and sequestration capacity of managed forests, unlocking new upside revenue from carbon markets.
