What is biochar in simple terms?

Biochar is a stable form of charcoal made by heating biomass (wood, crop residue, manure) in a low-oxygen environment — a process called pyrolysis. The result locks roughly half the feedstock's carbon into a solid form that can stay in soil for centuries to millennia instead of breaking down and re-releasing CO₂.

What is the price of biochar per ton in 2026?

Bulk physical biochar typically sells for $400–$1,200 per metric ton depending on feedstock, particle size, and region. Premium horticultural and inoculated biochar can hit $1,500–$3,000 per ton. Biochar carbon removal credits (CDR) trade separately at roughly $100–$250 per tonne of CO₂ removed — driven by Puro.earth listings and corporate purchases from Microsoft, Frontier, Stripe, and Shopify.

How does biochar remove carbon?

Plants absorb CO₂ as they grow. Normally that carbon returns to the atmosphere when biomass decomposes or burns. Pyrolysis interrupts the cycle: it converts the biomass into biochar (~50% carbon by mass) that is chemically stable for 100–1,000+ years when stored in soil, concrete, or asphalt. The IPCC counts biochar as a durable carbon dioxide removal (CDR) pathway.

Is biochar carbon credit better than tree-planting credits?

They solve different problems. Tree-planting credits are cheaper and have co-benefits like biodiversity and community jobs, but permanence is decades (and reversible through fire or logging). Biochar credits cost more per tonne but deliver centuries-scale permanence and are favoured by corporate buyers with strict CDR mandates. Most serious portfolios use both.

How is biochar verified and certified?

The two leading standards are Puro.earth Biochar Methodology and the European Biochar Certificate (EBC) C-Sink. Both require third-party MRV (Monitoring, Reporting, Verification) covering feedstock sourcing, pyrolysis conditions, biochar mass produced, and end-use. Carbon removal is only credited when biochar is applied in a way that prevents re-release for at least 100 years.

How can my business buy biochar carbon credits?

You can purchase directly from producers via Puro.earth or buy bundled CDR portfolios from intermediaries like Frontier, Supercritical, Climate Impact Partners, Patch, and Carbonfuture. For programmatic, pay-as-you-go integration, an environmental API like 1ClickImpact lets you trigger removal actions with each customer transaction instead of buying credits in bulk upfront.

What Is Biochar?

Biochar is a stable, carbon-rich form of charcoal made by heating biomass — wood, crop residue, manure, sawmill chips — in a low-oxygen environment. The process is called pyrolysis. Roughly half of the feedstock's carbon ends up locked inside a solid that resists decomposition for centuries to over a thousand years.

Biochar matters in 2026 because corporate buyers like Microsoft, Frontier, Stripe, and Shopify have started spending hundreds of millions of dollars on durable carbon dioxide removal (CDR) — and biochar is one of the few methods that's commercially scaled today, costs less than direct air capture, and stores carbon long enough to count under strict net-zero frameworks.

This is the business guide we wish we'd had when researching biochar: what it is, how it's made, what it costs per ton, what credits cost per tonne of CO₂, how it compares to other CDR methods, and how to buy it. With links throughout to 1ClickImpact for businesses that want to start funding verified climate impact today.

How Biochar Removes Carbon (and Why It Stays Removed)

Plants pull CO₂ out of the air as they grow. Normally that carbon goes right back when the plant decomposes, burns, or is eaten. Biochar interrupts that cycle.

Pyrolysis heats biomass to between 300°C and 700°C in a kiln or reactor with almost no oxygen. Instead of fully combusting (which releases CO₂), the biomass thermally decomposes. The hydrogen and oxygen are driven off as bio-oil and syngas. What remains is biochar — a highly aromatic, structurally stable form of carbon.

That stability is the whole game. Buried in soil, mixed into concrete, or stored in landfill cells, biochar's carbon stays locked for 100–1,000+ years. The IPCC, ICVCM Core Carbon Principles, and the major durable CDR standards (Puro.earth, EBC C-Sink) all recognise this permanence and credit it accordingly.

How Biochar Is Produced

A simplified four-step view of an industrial biochar pipeline.

Step 1

Feedstock collection

Agricultural residue, forestry waste, sawmill chips, or even manure are gathered as biomass inputs.

Step 2

Pyrolysis (300–700°C)

Biomass is heated in a low-oxygen kiln. The chemistry locks ~50% of the feedstock's carbon into stable biochar.

Step 3

Co-product capture

Bio-oil and syngas come off as byproducts and are often used to power the kiln — making the process closer to energy-positive.

Step 4

Application & verification

Biochar is applied to soil, mixed into concrete, or used as a filter medium. Each tonne is tracked through Puro or EBC for carbon credit issuance.

Biochar Price Per Ton in 2026

Biochar pricing splits cleanly in two: the physical biochar sold by the metric ton, and the separate carbon removal credit sold per tonne of CO₂. Both are quoted below using 2026 reference ranges from Puro.earth listings, EBC C-Sink data, Frontier offtakes, and producer price sheets.

Product / segment	Price range (2026)	Notes
Bulk agricultural biochar	$400–$700 / metric ton	Coarse particle, basic feedstock — sold by the tonne for soil amendment.
Premium horticultural biochar	$800–$1,500 / metric ton	Sieved, low ash, sometimes inoculated with microbes.
Activated / specialty biochar	$1,500–$3,000 / metric ton	Higher surface area for water filtration, livestock, or industrial uses.
Biochar CDR carbon credits	$100–$250 / tonne CO₂	Tradeable carbon removal certificate (Puro, EBC). Separate from physical biochar.
Frontier / large-tender pricing	$130–$200 / tonne CO₂	Aggregated corporate buyer pricing across multiple producers.

Ranges vary by region, feedstock, certification status, and contract volume. Spot prices fluctuate; long-term offtakes (3–10 year) typically trade at the lower end.

Biochar vs Other Carbon Removal Methods

Biochar sits in the middle of the durable CDR market — more expensive than nature-based credits, much cheaper than direct air capture, with permanence that's good enough for most corporate net-zero targets.

Method	Cost per tCO₂ (2026)	Permanence	Scalability
Tree planting (nature-based)	$5–$50	Decades	Very high
Soil carbon	$15–$80	Decades	High
Biochar	$100–$250	Centuries+	Medium-high (limited by feedstock)
Enhanced rock weathering	$200–$400	Millennia	Medium
BECCS	$150–$400	Millennia	Medium
Direct Air Capture (DAC)	$400–$1,000+	Millennia	Low today, growing

Biochar Applications: Where the Carbon Actually Ends Up

Biochar is only credited as CDR when it's applied in a way that prevents re-release. Here are the dominant end-use markets.

Agriculture & soil amendment

Improves water retention, reduces fertiliser need, and boosts yields. The dominant end-use globally.

Concrete & asphalt additive

Replaces a portion of cement filler — locking carbon into long-lived infrastructure. Companies like Carbon Drawdown and Carbicrete lead here.

Water & stormwater filtration

Activated biochar removes heavy metals, PFAS, and nutrient runoff. Used in green infrastructure and municipal filtration.

Livestock feed additive

Small inclusions in cattle feed reduce enteric methane and improve gut health. A growing application in dairy and beef.

Why Businesses Are Buying Biochar Credits

Permanent carbon storage. Locks carbon away for 100–1,000+ years — qualifying as durable CDR under ICVCM and corporate net-zero standards.
Co-benefits beyond carbon. Boosts soil fertility, reduces fertiliser dependency, holds water in drought-prone regions, and lowers livestock methane.
Distributed production. Pyrolysis units can run at farm scale, regional facility scale, or industrial scale — no one mega-plant needed.
Waste-to-value. Turns agricultural and forestry waste streams into a high-value carbon product instead of burning or composting them.
Verifiable & certifiable. Puro Biochar and EBC C-Sink give buyers third-party MRV — credits are auditable end to end.

How to Buy Biochar & CDR for Your Business

There are three practical routes. Each works — they fit different stages of corporate climate maturity.

Direct from producer

Puro.earth marketplace, EBC-certified producers, or off-take deals. Best for large, programmatic buyers with procurement teams.

CDR portfolio buying

The Bottom Line on Biochar

Biochar is one of the few carbon removal technologies that's already commercial, durably permanent, and significantly cheaper than direct air capture. Bulk physical biochar runs $400–$1,200 per ton, and biochar carbon removal credits trade at $100–$250 per tonne of CO₂. Demand is being pulled forward by Microsoft, Frontier, Stripe, and Shopify, and the supply pipeline is scaling fast.

For most businesses, the smart play isn't building a procurement team to negotiate biochar off-takes — it's working with a platform that handles the verified-removal side for you. That's exactly the gap 1ClickImpact closes: per-action carbon capture and removal, transparent MRV, ready-made integrations.
