Carbon removal
Biochar Carbon Removal (BCR) is an approach for extracting carbon dioxide from the atmosphere by utilizing the carbon plants naturally capture and store in biomass through photosynthesis.
Organic residues are exposed to high temperatures (typically around 300–700 °C, depending on the process) in an oxygen-limited environment — a process known as pyrolysis. During this thermochemical transformation, the complex organic materials in the biomass break down, and volatile compounds are released as gases. The remaining material is a stable, carbon-rich solid called biochar, which can be safely stored for long periods. In addition to producing biochar, the process can also generate renewable energy and other valuable by-products. Biochar is tested for parameters such as carbon content, H/C ratio, moisture content, ash, and contaminants — important for safety, performance, and MRV.
BCR plays an important role in net-zero strategies because it permanently removes atmospheric carbon while creating useful outputs that can displace fossil-based resources. By locking carbon into a stable form, biochar helps counterbalance emissions that are difficult to eliminate entirely. This makes BCR a practical carbon removal pathway that complements emission reduction efforts, supporting organizations and governments in achieving long-term climate targets and transitioning toward a net-zero future.
CO₂ Removal Certificate
The technology of biochar is a net-negative emission process: CO₂ is removed from the atmosphere and stored.ne CO₂ Removal Certificate usually represents 1 metric ton of CO₂ equivalent (CO₂e) that has been removed from the atmosphere and safely stored.
With this “climate-negative” technology, converting waste into a carbon sink, the CO₂ Removal Certificates are highly sought after by corporations aiming for net-zero, acting as a reliable, long-term removal solution.
Why biochar CDR is particularly strong compared to other methods
1. Durability: century-scale storage is realistic
Biochar is considered one of the durable CDR options because a large portion of its carbon degrades very slowly. Studies modeling and reporting on suitable biochars frequently show high BC100 values (the share of biochar carbon still present after 100 years) — depending on feedstock and H/C ratio, often roughly in the ~70–80% range (and sometimes higher).
This represents a key difference compared to many nature-based approaches, where reversal or loss risks play a larger role.
2. Measurability & MRV: physical mass balance instead of estimation
Biochar CDR allows large parts of the accounting to be based on measurable material flows: input biomass → output biochar (mass and carbon content), combined with process data and emissions deductions. This simplifies monitoring, reporting, and verification compared to purely model-based approaches.
That biochar is being seriously considered as a “permanent removal” is reflected in regulatory developments in the EU: in early February 2026, the European Commission adopted the first voluntary certification methodologies for permanent carbon removals under the CRCF framework — including biochar.
3. Scalable today: not a “bet on 2040”
Biochar systems are based on mature thermochemical processes and can be scaled modularly. Within the durable CDR market, biochar is already a major driver of real delivery volumes — not just pilot-stage discussion.
4. Cost-benefit profile: often competitive among durable removals
Compared with some high-capex options (e.g., DACCS), biochar CDR is often more accessible from a cost perspective while maintaining high durability. Market indicators (e.g., CORCCHAR index/market reports) in 2025/2026 frequently show price levels roughly around ~125–145 USD/tCO₂e (depending on quality, standard, and volume), with some analyses reporting higher averages.
(For website use, this is best framed as a “typical market range,” not a guarantee.)
5. Co-benefits without distraction
Beyond its CDR effect, biochar can provide additional benefits (e.g., as a material in agriculture, substrates, or construction). This can make projects economically more resilient — provided the CDR accounting remains clearly separated and conservatively calculated.
Why companies should invest in permanent carbon sinks
1. Because Net Zero is not credible without removals
The IPCC makes it clear in AR6 that carbon dioxide removal (CDR) plays a role in many pathways — especially for addressing residual emissions and achieving long-term temperature goals.
Roadmaps such as those from the International Energy Agency also emphasize the need for CO₂ removal/CCUS components in Net Zero pathways.
2. Because “permanent” represents a different quality level than “temporary”
Many nature-based measures are important, but their climate benefit can be reversible (e.g., due to fire, drought, or management changes). Durable storage solutions reduce this risk — and with it reputational and verification pressure.
3. Because standards are clearly moving toward durable removals
The revised University of Oxford principles (Oxford Principles, 2024) explicitly call for a transition toward carbon removals and durable storage, particularly for neutralizing residual emissions.
The Science Based Targets initiative also positions “Beyond Value Chain Mitigation” as a way to invest beyond a company’s own targets — including removals.
4. Because early action reduces procurement and price risk
Durable CDR remains scarce. Companies that establish partnerships and multi-year offtake agreements early secure supply volumes, learning advantages, and better integration capabilities — rather than being forced into costly last-minute purchases.
5. Because it is strategically superior to last-minute offset shopping
Permanent carbon sinks can be treated as long-term climate infrastructure: predictable, auditable, and less vulnerable to reversal debates — making them more compatible with auditors, investors, and emerging regulatory frameworks.
