What They Do

InterEarth is a biomass storage company turning low-value, marginal agricultural land into a valuable carbon sequestering asset. Through their coppicing method and biodiverse native tree selections (which, are well-adapted to the low-rainfall environments, notably in Western Australia, their first base of operations) they have developed a system of continuous and rapid drawdown that, when combined with below-ground or vaulted biomass storage, results in high value, durable and scalable carbon removal with considerable additional social and environmental benefits.

Why It Matters

We love companies that solve multiple problems with simple yet elegant solutions. Photosynthesis is clearly a proven and efficient way to capture CO₂ and, when combined with burial, provides a low-cost but high quality storage solution too. Biomass burial stands out as an immediately scalable route to carbon removal, however it is important that feedstocks are true waste, with limited competing uses, or where land is truly marginal and uneconomic or undesirable for growing food. InterEarth is initially operating in Western Australia, storing waste biomass and also returning mixed, deep-rooted native vegetation to marginal and overworked farmland while leveraging the most damaged areas (usually through secondary salination caused by over-cropping) for storage. This is true ‘carbon farming’ and a scalable route to sequestering genuinely additional CO₂ while also reinvigorating local employment, managing fire risk and increasing biodiversity plus, over the long term, improving soil quality and giving a chance for these lands to slowly revive.
