Biochar
Biochar is a stable, carbon-rich material produced by heating organic biomass in the absence of oxygen (pyrolysis), which can sequester carbon in soil for hundreds to thousands of years.
What is Biochar?
Biochar converts organic waste (wood chips, crop residues, manure) into a stable form of carbon that resists decomposition. When added to soil, biochar can persist for 100–1,000+ years, providing durable carbon sequestration. It also improves soil health, water retention, and agricultural productivity. Biochar is gaining traction in the voluntary carbon market as a high-permanence removal credit, priced between £80 and £200 per tonne of CO₂e.
Practical Examples
A company purchases biochar carbon removal credits at £120/tCO₂e, valuing the 500+ year permanence for its net zero claim.
A farm produces biochar from crop waste through pyrolysis, sequestering carbon while improving soil fertility and reducing waste emissions.
How Climatise Helps
Climatise helps organisations evaluate biochar and other removal options by quantifying residual emissions that require offsetting.
