The Biochar Carbon Removal Industry

Biochar accounted for 86% of all carbon dioxide removal (CDR) deliveries in 2024, making it the most commercially mature permanent carbon removal pathway. The global biochar market reached approximately $838 million in 2026, projected to exceed $2.2 billion by 2034 at a 13.4% CAGR.

How Biochar Sequesters Carbon

Pyrolysis converts biomass into a stable, carbon-rich solid that resists decomposition for centuries. One tonne of biochar typically sequesters 2.5 to 3.2 tonnes of CO₂, depending on feedstock and process conditions. The IPCC recognizes biochar as a proven negative-emission technology with 100+ years of carbon permanence.

Market Structure and Key Players

The industry remains highly fragmented—the top five producers control well under 30% of installed capacity. Global annual production exceeds 350,000 metric tonnes of biochar, with capacity growing rapidly:

Company	Annual CO₂ Removal	Notable Deal
Exomad Green	260,000 t	1.24M tonne offtake with Microsoft (2025)
Varaha	50,000+ t	100,000 tonne deal with Google (2025)
Aperam BioEnergia	40,000 t	Puro.earth certified, expanding 3x by 2026

Certification and Registries

Carbon credit buyers rely on third-party verification. The dominant registries for biochar carbon removal include:

Puro.earth: Issues CO₂ Removal Certificates (CORCs) under the Puro Standard. Over 20 biochar suppliers across 13 countries. Acquired by Nasdaq.
Carbon Future: Full chain-of-custody tracking from production to soil application, with European Biochar Certificate (EBC) integration.
Isometric: Science-first registry with rigorous LCA-based verification protocols.

Demand Drivers

Corporate net-zero commitments are the primary demand catalyst. Microsoft, Google, Stripe, and Swiss Re have collectively contracted hundreds of thousands of tonnes of biochar-based carbon removal. Meanwhile, agricultural distributors increasingly source biochar as a dual-purpose product—improving soil water retention and nutrient cycling while generating carbon credits from the same material.

Frequently Asked Questions

Q.How is the production capacity data collected?

When you request this dataset, our AI crawls public sources including company websites, registry filings (Puro.earth, Carbon Future), press releases, and industry reports to compile the latest capacity figures. Data reflects publicly disclosed information only.

Q.Does the list include companies selling carbon removal credits?

Yes. Each entry indicates whether the company sells certified carbon removal credits and through which registry (Puro.earth, Carbon Future, Isometric, etc.), so you can identify credit suppliers directly.

Q.Are small-scale and artisanal biochar producers included?

The dataset focuses on commercially active producers with verifiable public information. Very small kiln operators without a web presence may not appear, but mid-scale producers with published capacity data are covered.

Q.Can I filter by feedstock type or pyrolysis technology?

Yes. You can specify feedstock (forestry residue, crop waste, sewage sludge, etc.) or technology type (slow pyrolysis, flash pyrolysis, gasification) to narrow results to suppliers matching your requirements.
