The voluntary carbon market is undergoing a fundamental shift. Following years of scrutiny over the integrity of nature-based offsets — particularly REDD+ forestry credits — corporate buyers are moving decisively toward engineered carbon dioxide removal (CDR). Biochar is at the forefront of this transition.
Why Biochar Stands Out
Biochar’s permanence story is compelling: carbon fixed into stable aromatic structures at pyrolysis temperatures above 400°C remains sequestered for hundreds to thousands of years. Unlike biological sequestration, biochar is not subject to reversal from drought, fire, or disease.
On the additionality front, GBG’s biochar displaces conventional charcoal production that causes significant deforestation and black carbon emissions. The intervention is additional — it would not happen without the carbon revenue.
Pricing and Demand
Biochar CDR credits currently trade at USD 150–300 per tonne CO₂e on platforms including Puro.earth, with strong forward demand from European and North American corporate buyers. East African production costs, anchored by low-cost plantation biomass and local labour, position GBG competitively relative to European and North American producers.
