Every standard a serious buyer needs — in one platform

Carbon registries are the foundational layer of market integrity. They maintain the public record of every credit issued, transferred, and retired — preventing double-counting and providing the audit trail that institutional buyers and regulatory frameworks require. Not all registries are equal in credibility, methodology rigour, or institutional recognition.

Most institutional buyers now require at least one independent rating before purchasing. Ratings agencies assess additionality (would the carbon project have happened anyway?), permanence (will the carbon stay sequestered?), co-benefits (are social and ecological impacts real and verified?), and MRV integrity (is monitoring credible?).

Stasis Carbon biochar credits carry the full ratings stack — all four major agencies:

ARR Agroforestry note: The Sylvera Rating Pending rating engagement for the ARR project has been initiated and is expected within 4–6 months. BeZero rating application is in queue. All project ratings are currently under process. ICR registry issuance is complete. Buyers should factor rating timelines into their due diligence.

The Integrity Council for the Voluntary Carbon Market (ICVCM) is an independent governance body established in 2021 to restore confidence in voluntary carbon markets. Their Core Carbon Principles (CCP) define the minimum quality standard a carbon credit must meet to be considered institutional grade.

CCP approval is granted at the methodology level — not the project level. A registry methodology (e.g. Verra VM0044) is assessed against 10 core principles covering: additionality, permanence, no net harm to host communities, MRV robustness, and sustainable development co-benefits.

Verra VM0044 v1.2 — the methodology underpinning our Biochar CDR project — has received ICVCM CCP approval. This means every credit issued under VM0044 v1.2 carries the CCP label, which can be stated in CSRD disclosures, CDP A-list submissions, and SBTi annual reports.

Why does this matter for CSRD buyers specifically? CSRD Article 8 requires companies to disclose their climate transition plan, including the quality of carbon credits used. Regulators and auditors increasingly expect CCP-labelled credits for removal and reduction claims. A credit without CCP approval may face challenge during CSRD audit.

The European Biochar Certificate (EBC) is the most rigorous independent quality standard for biochar globally. EBC Gold — the highest tier — requires quarterly laboratory testing of the biochar product itself, not just process monitoring.

What EBC Gold quarterly lab testing requires:

• CHNS elemental analysis — measures carbon (Corg%), hydrogen, nitrogen, and sulphur content
• H:Corg ratio — the key permanence indicator. Our biochar maintains ≤0.38, confirming 100–1,000+ year stability. EBC Gold ceiling is 0.70; Puro CORC200+ requires ≤0.50; our process achieves ≤0.38.
• BET surface area — determines soil amendment and water retention potential (co-benefit evidence)
• PAH content — confirms absence of polycyclic aromatic hydrocarbons (safety certification)
• Heavy metals panel — arsenic, cadmium, lead, mercury, chromium, copper, zinc, nickel

These certificates are produced by EBC-accredited independent laboratories, not by the project operator. They are issued quarterly and published in full to any buyer upon request. They form the physical basis of the permanence claim in every Puro.earth CORC200+ credit we issue.

India's Carbon Credit Trading Scheme (CCTS) is the domestic compliance carbon market being established under the Energy Conservation (Amendment) Act 2022. Three bodies share governance responsibility:

Trading launch is targeted for 2026. The following sectors face compliance obligations under Phase 1:

Our Solar Avoidance project and ARR Agroforestry project are directly eligible as CCTS supply-side instruments. CCTS compliance buyers can purchase these credits to meet their obligations — at the BEE floor price of Rs.1,500/t for solar, and market rates for ARR. The biochar CDR project qualifies under CCTS but is primarily marketed in the premium voluntary tier (Puro CORC200+) where pricing is significantly higher.

Science Based Targets initiative (SBTi): The SBTi Corporate Net-Zero Standard requires companies to achieve near-zero emissions by 2050, with 90%+ absolute reduction. The remaining ≤10% "residual emissions" must be neutralised using permanent carbon dioxide removal — not avoidance credits, not offset credits. From 2030, CDR is effectively mandatory for SBTi companies to claim net-zero. Our Biochar CDR (Puro CORC200+, Rating Under Process, ICVCM CCP-approved) is specifically designed for this use case. EBC Gold certification and H:Corg ≤0.38 permanence are the technical basis for the permanence claim.

Corporate Sustainability Reporting Directive (CSRD — EU): CSRD Article 8 requires European companies to disclose their climate transition plan, including carbon credit quality metrics. The European Sustainability Reporting Standards (ESRS) E1 standard specifies that credits used in net-zero claims should: be from high-quality projects, carry independent third-party ratings, align with ICVCM Core Carbon Principles, and include co-benefit documentation. Our ARR project specifically addresses CSRD biodiversity disclosure requirements — the tree cover expansion, SDG 15 (Land and Life), and the verified farmer benefit-sharing mechanism all provide the co-benefit evidence CSRD auditors require.
