Volume mix
Retirement mix: removal vs avoidance
Calendar year 2025
10% Removal
90% Avoidance / reduction
Source: MSCI Carbon Markets (global retirements across 18 registries). Nearly all removal retirements in 2025 were nature-based. Engineered removal remains a small share of volume but a large share of value.

Regulatory note
SBTi Corporate Net-Zero Standard V2.0
Published June 2026. Category A companies must support removals from 2035 (1% of ongoing Scope 1 to 3 emissions, rising to 100% by net zero), with long-lived removals ramping from 10% in 2035 to 100% at net zero. Residual emissions at net zero must be neutralised with eligible removals, not avoidance.
Pricing disclaimer
Reference data, not a quote
These are published reference figures for Calendar year 2025, not a Carma quote. Final pricing depends on project type, vintage year, and contracted volume.

What we sell
Carbon Carma supplies two things: verified carbon removal, and tailored high-quality avoidance. Nothing else. We work through curated project developers, retire credits onto recognised registries, and vet every project through our Verified Impact framework before it reaches you.
Removal credits
Credits from curated project developers for verified carbon removal: engineered removal such as biochar, and durable nature-based restoration that pulls carbon out of the atmosphere and stores it. We do not buy off a registry shelf; we select developers, then retire credits onto the appropriate registry.
Retired onto: Puro.earth, Verified Carbon Standard, Gold Standard, Woodland Carbon Code.
Best for: neutralising residual emissions under a net zero target, including SBTi-aligned removal requirements.
High-quality avoidance credits
Credits from curated project developers for verified emissions avoidance: methane capture and destruction, and selectively screened forest protection. We only take avoidance where the methodology is approved against the ICVCM Core Carbon Principles, the vintage is recent, and the project clears our proof bundle. The generic sub-five-dollar avoidance credit is exactly what we do not sell.
Retired onto: Verified Carbon Standard, Gold Standard.
Best for: balancing the carbon ledger during the transition, after you have reduced everything you can.
Pricing
Quotes are set per engagement against project type, vintage year, and contracted volume, from a first verified purchase through to multi-year offtakes. Enquire now for a scoped quote.
The market has changed
In calendar year 2025, about 10% of global credit retirements were removals and 90% were avoidance or reduction (MSCI Carbon Markets). Buyers still need both, but they now need regulator-defensible reporting, supply security, and visible co-benefits. Three shifts are driving that. Integrity frameworks, led by the ICVCM Core Carbon Principles, are setting a quality baseline that legacy credits fail. The SBTi Corporate Net-Zero Standard V2.0 (June 2026) hardens demand for durable removal, including mandatory removal support from 2035 for Category A companies, and in 2024 removal credits averaged a 381% price premium over reduction credits (Ecosystem Marketplace). Disclosure regimes from CSRD to TNFD mean every credit you retire will be reviewed by people whose job is to find the weakness in it. Carbon Carma exists for that scrutiny.
How we vet a project
The proof bundle
Every carbon project we consider runs through a structured nine-slot vetting framework. We call it the proof bundle.
Registry and baseline
Methodology and quantification
Monitoring, reporting, verification (MRV)
Additionality
Permanence and reversal risk
Leakage
Double-counting defence
Stakeholder engagement and safeguards
Risk coverage
Due diligence
How a project moves through the framework
Each project from a curated developer is cross-checked for consistency before sign-off. Four checks run on every credit: volumes, vintage, VVB independence, registry consistency. Where an independent risk rating exists, such as a BeZero Carbon rating, we review it as an additional layer of due diligence on top of registry certification. Final review is human, structured against the nine-slot framework.
Evidence trail
Where the proof lives
Projects that clear the proof bundle are published to IPFS and the Carma Climate Ledger today: public, blockchain-anchored project and credit records. Retirement-record publication is rolling out to production; until that is complete, clients still receive credit-level retirement documentation for audit use.

Retirement records
Credit-level retirement records, traceable on the Carma Climate Ledger.
Tracking
Project tracking on every credit: location, status, and MRV data.
Framework data
Data formatted to feed TNFD-aligned, CSRD-aligned, or B Corp evidence packs.
Substantiation pack
Evidence-backed documentation your comms and legal teams can stand behind for any public claim.
Annual review
Annual review meetings with your sustainability and finance leads, covering reporting updates, portfolio adjustments, and next-cycle planning.
Your auditor and your reporting team own the disclosure. We give them the evidence packs listed above.
Claim hygiene
What we don't claim
Voluntary carbon markets have lost trust through overclaiming. We are trying to do this differently.
We are not the certifier. Registries are. Carma is an agnostic layer: we curate project developers, retire credits onto the right registry for each project, and hold memberships where they matter, including Woodland Carbon Code and Puro.earth.
We do not claim carbon neutrality on your behalf. We do not promise zero emissions. We do not say “climate positive.”
We sell credits and run projects whose impact is verifiable. We give you data your auditor can review. Measurement, reduction, and disclosure remain your team's work; we supply the credit evidence and reporting packs that sit alongside that work.
Standards and memberships
Carma is registry-agnostic. We curate project developers; credits retire onto recognised standards. We are members of the Woodland Carbon Code and Puro.earth, and we work with Verra VCS and Gold Standard where those registries are the right retirement home for a project.
B Corp certified
Carma is B Corp certified. B Impact Score 127.9, independently assessed against social and environmental standards.
Woodland Carbon Code
Carma is a Woodland Carbon Code member. UK woodland projects we work with can retire under the Code.
Puro.earth
Carma is a Puro.earth member. Engineered removal, including biochar, can retire under the Puro Standard.
Verified Carbon Standard
Registry-agnostic retirement: credits from curated developers can retire onto Verra VCS registries.
Gold Standard
Registry-agnostic retirement: credits from curated developers can retire onto Gold Standard registries.
