Biological residues
Plants capture CO₂ as they grow. Instead of letting forestry and farming residues decompose and release it again, we use them as raw material for biochar production.
Biochar
Durable carbon removal
Biochar is one of the most reliable and scientifically grounded approaches to long-term carbon removal available today. Unlike conventional emissions reductions, it actively removes carbon dioxide already in the atmosphere, making it a powerful complement to other climate action.
How it works
From waste to climate benefit
Turning forestry and farming residues into stable carbon. At roughly ten times the cost of standard carbon credits, biochar sits outside conventional climate portfolios. However, it offers individuals and businesses a meaningful way to go beyond conventional carbon credits and invest directly in durable, verifiable carbon removal.
Pyrolysis
The residues are heated to 350–1000 °C in an oxygen-free kiln. This process, called pyrolysis, converts the biomass into biochar.
Stable carbon
The result is a stable, dust-free form of carbon. One tonne of biochar locks in roughly 2.5 tonnes of CO₂ for at least 100 years, and likely far longer.
Soil improvement
Sold as a soil improver, biochar retains water and nutrients, and boosts soil structure. It cuts irrigation and fertilizer needs, supports plant health, captures extra carbon, and builds resilience to extreme weather.
Why should we start funding Durable Carbon Removals today?
- Long-lived carbon removal, not just reduction — carbon locked in soil for 100+ years, independently verified.
- Scaling up solutions — by supporting carbon removal solutions in their early days, we help drive down costs and ensure supply for the net zero transition.
- Future-proof against tightening standards — meets the long-lived removal criteria SBTi requires from 2035.
