Market Volumes and Pricing

Chapter-length synthesis of biochar carbon removal (BCR) market volumes and price signals as of 2026-09-14. Figures are from primary / high-signal public sources only—chiefly CDR.fyi abridged reports and Puro × Nasdaq indexes. Do not treat this note as live market data; re-pull sources before diligence.

1. How to read the three volume metrics

MetricWhat it measuresWhy it matters
Contracted / purchasedForward offtakes + spot sales reported to trackersDemand & bankability; dominated by multi-year megadeals
DeliveredTonnes actually issued / delivered ex-postOperational proof; BCR leads all durable CDR methods here
RetiredTonnes cancelled on a registry for a climate claimFinal use of the credit; liquidity + claim integrity

CDR.fyi tracks durable removals (hundreds to thousands of years permanence). Coverage claim in Q1 2026 notes: ~97%+ of publicly disclosed durable CDR contract volume (methodology caveats).


2. Cumulative BCR volumes (Q1 2022 → H1 2025)

Growth narrative

  • 2022–2024: purchase tonnage roughly tripled year-over-year; 2024 purchases exceeded all prior years combined.
  • Q2 2025: largest BCR quarter ever, driven by Microsoft–Exomad Green ≥1.24 Mt (Exomad May 2025; Historical Deals).
  • Deliveries and retirements roughly doubled annually 2022–2024; Q1–Q2 2025 retirements were closer to flat vs year-ago quarters (+12% / +0.4%).

BCR’s role inside durable CDR

Share typeBCR sharePeer context
Durable CDR deliveries (since Q1 2022)~86%Delivery leader
Durable CDR retirements~92%Retirement leader
Durable CDR contracted~10%BECCS ~75% of contracted; DAC ~9%

Interpretation: biochar is the workhorse of delivered/retired tonnes and the default entry method for new buyers, while BECCS dominates headline contracted megatonnes that may take years to deliver.

Market value series (pricing basis from 2024 YIR)

Using CDR.fyi’s 2024 Year-in-Review pricing basis applied to BCR volumes (Snapshot 2025):

YearEst. BCR market value
2022$14.6M
2023$33.9M
2024$181.5M

CAGR 131.6% (2022–2024). Exact BCR $/t averages are not published in the abridged Snapshot.

Structural warning from CDR.fyi

Headline volume remains buyer-concentrated. Q1 2026 was strong vs prior Q1s but a step down from mid-2025’s exceptional pace. Expanding the buyer pool (software, finance, professional services; residual-heavy sectors) is framed as necessary for sustained growth—see Buyers and Offtakes · Risks and Controversies.

CORCCHAR < CORCX in this snapshot: biochar trades at a discount to the all-CORC composite on reported near-term Puro transactions—not proof of a global BCR discount vs Verra/Isometric/CSI.

5.3 Index vs bilateral offtakes

ChannelCharacteristics
Index (CORCCHAR)Near-term reported CORC trades; transparent €/t level; Puro-only
Spot platform inventoryCertified tonnes; may track near index
Multi-year offtakesFirm + optional volumes; prices usually confidential; may embed delivery risk, co-benefits, dMRV requirements
Intermediated portfoliosSupercritical, Senken, Watershed, Patch, Carbonfuture, etc.; 74% of Q1 2026 tonnes

Science-side abatement cost ranges (e.g., literature ~$70–360/t) are not credit market prices—see Quantitative Benchmarks.

5.4 Quality-tier effects on price

Public abridged sources do not quantify CCP-label or 1000-year-path premiums in $/t. Practical segmentation hypotheses (unverified price deltas):

  1. Buyers requiring CCP methodology labels today may prefer Verra VM0044 VCUs.
  2. Buyers requiring 1000-year Ro / burial may prefer Isometric Biochar Protocol (e.g., Carba–Microsoft).
  3. Buyers optimizing near-term delivery + CORCCHAR discovery may prefer Puro CORC200+ inventory.
  4. Uncertified marketing claims should clear at zero credit value for neutralization accounting (Durable CDR Quality Tiers).

6. Liquidity & cycle time

SignalFigureSource
Puro biochar CORC issuance → transfer/retirement95 days (2021) → 22 days (mid-2025)Snapshot 2025 citing Puro Aug 2025 report
Retired : delivered (BCR cumulative)~50% by end-Q2 2025Snapshot 2025
Intermediary share of Q1 2026 tonnes74%Q1 2026

Faster CORC turnover improves working-capital dynamics for suppliers on the Puro stack (Puro Project Cycle and MRV · Puro Pricing and CORC Indexes).


7. Why buyers choose BCR (volume implications)

From Snapshot business-case synthesis (Swiss Re, SEB, Tide, Nasdaq, and diversified majors):

  1. Rapid contracting → delivery relative to DAC/BECCS.
  2. Lower prices relative to many engineered methods (qualitative; exact differentials sparse).
  3. Ability to start small (<100 t trials) — explains 290 unique purchasers.

These structural advantages explain why BCR can be ~10% of contracted durable CDR yet ~86–92% of delivered/retired tonnes.


8. Gaps / what isn’t public

  1. Exact BCR average $/t series (only +18% and market-value aggregates in abridged YIR/Snapshot).
  2. Unit prices on Microsoft–Exomad, Microsoft–Liferaft, Google–AMP, Altitude–Empacar, Supercritical–Exomad.
  3. Full registry mix of delivered BCR (Puro vs Verra vs Isometric vs CSI) in abridged posts.
  4. Post–Q1 2026 quarterly abridged update (none fetched as of 2026-09-14 beyond May 2026).
  5. Option volumes, take-or-pay schedules, and penalty clauses in offtakes.
  6. Private inventory and OTC desk quotes outside CORCCHAR.
