PLENA Carbon & Climate Finance Attestation
Human-witnessed receipts for carbon projects that satellites cannot fully verify. Built for the voluntary and compliance carbon markets, the climate disclosure regimes of the SEC and EU CSRD, and the project communities whose Free, Prior, and Informed Consent is the difference between a credit that means something and one that does not.
Opening problem
The voluntary carbon market runs between one and two billion US dollars annually. The compliance carbon market — the EU Emissions Trading System, the UK ETS, California's Cap-and-Trade, the Chinese national ETS, Korea's ETS, and regional systems — moves roughly eight hundred fifty billion US dollars in covered emissions. Climate disclosure regimes are rolling out globally: the SEC climate disclosure rules, the EU Corporate Sustainability Reporting Directive, the ISSB's IFRS S1 and S2 standards. Trillions of dollars in capital allocation are being made on the basis of claims about emissions, offsets, and transition plans.
The integrity of those claims is in crisis. Verra-issued credits have been repeatedly invalidated by independent investigation. Gold Standard projects have faced similar scrutiny. The Integrity Council for the Voluntary Carbon Market published its Core Carbon Principles in 2023 explicitly because the existing infrastructure was producing too many credits that represented too little carbon. The compliance markets are not immune: leakage, additionality questions, and verification gaps recur.
The structural problem is that existing verification is dominated by two modes: registry self-regulation (Verra, Gold Standard, ACR, CAR validate the projects they list) and remote sensing (satellite-based MRV measures what it can see from orbit). Both have known failure modes. Registry self-regulation has conflict-of-interest exposure. Remote sensing cannot see what happens inside a community, how consent was obtained, whether benefit-sharing arrangements are real, or whether the people on the land agreed to be part of the project.
PLENA Carbon & Climate Finance Attestation is built to address this gap. Not by issuing or validating carbon credits, not by measuring emissions, and not by replacing third-party verifiers (the DOEs and VVBs that perform formal validation and verification under the various standards) — but by producing the human-witnessed receipt layer that complements satellite-based MRV and registry self-regulation: project community attestation of consent, witnessed declarations of project conditions, refreshed annual confirmations, and the receipt chain for credits from issuance through retirement.
Five cases PlenaProof covers
For each case, three actors share the work: the project (developer or community) makes the declarations, named witnesses (community representatives, local NGO partners, regional auditors — not satellites) attest, and PLENA seals the four-artifact bundle. Every artifact is an existing PLENA receipt format applied to a specific carbon-project or climate-disclosure need — no new platform, no new registry.
Project Origination Attestation
Witnessed declaration at project origination: the baseline argument, the additionality argument, the methodology choice, the host-country approvals, the project developer's identity and history. Sealed with the supporting documents. Designed to be readable years later by an auditor or investigative journalist trying to reconstruct what was claimed at the start versus what was true.
- Origination Declaration. Sealed statement of baseline, additionality argument, methodology choice, host-country approvals, developer identity and history.
- Sealed Evidence Packet. Project design document, host-country letters of approval, methodology selection rationale.
- Annual Yearbook. Year-over-year refresh recording any methodology revision or scope change.
- Multilingual Handover Packet to registries and verifiers. Drafted for Verra, Gold Standard, ACR, CAR, and Article 6 supervisory body intake.
Implementation and Monitoring Refresh
Periodic on-site witnessed receipts of project status, complementing satellite-based MRV. The witness is typically a community representative, a local NGO partner, or a regional auditor — not a satellite. The receipt documents what the satellite cannot see: relationships with neighboring landholders, displaced informal users, project staff conditions, partial implementation versus what was promised.
- Implementation Declaration. Sealed periodic statement of project status, including community relationships and staff conditions.
- Sealed Monitoring Evidence. Photographs, named-witness signatures, partial-implementation disclosures.
- Annual Yearbook. Trended year-over-year delivery against the original plan.
- Multilingual Handover Packet. Releasable to registries, buyers, and disclosing entities.
Community Benefit and FPIC Attestation
For projects on or affecting indigenous, traditional, or community lands, witnessed receipts of Free, Prior, and Informed Consent processes, benefit-sharing arrangements, and ongoing community standing. This case alone has standalone value for projects under IFC Performance Standard 7, the Voluntary Carbon Markets Integrity Initiative requirements, and the Article 6 supervisory body.
- FPIC Declaration with Community Witness. Sealed multilingual declaration of consent, with named community representatives as witnesses.
- Sealed Consent Evidence Packet. Recording of consultation meetings, signed assent rolls, translation attestations.
- Benefit-Sharing Refresh Yearbook. Confirms benefit flows year-over-year and surfaces disputes.
- Multilingual Handover Packet. Releasable in the community's language to registries, buyers, and ombudsman channels.
Credit Issuance and Retirement Receipts
Chain-of-custody for credits from project origination through registry issuance through corporate buyer acquisition through retirement, defending against double-counting and tracking the actual environmental claim each credit underwrites.
- Issuance Receipt. Sealed record of credit issuance under the named methodology and vintage.
- Transfer Chain Evidence. Each transfer between holders, with timestamps and named acquirer attestations.
- Retirement Declaration. Final retirement event, the disclosing entity, and the claim the credit underwrote.
- Multilingual Handover Packet to disclosing entities and regulators. Drafted for SEC, CSRD, ISSB, and Article 6 reporting.
Climate Disclosure and Transition Plan Attestation
For corporate disclosers under SEC, CSRD, or ISSB rules, receipts that the offsets they claim exist and behave as claimed, that the transition plans they publish are being implemented, and that the Scope 3 attributions they report are documented. Bridges from the project-level cases above to the discloser-level reporting obligation.
- Disclosure Position Declaration. Sealed statement of the disclosing entity's claims, with cited underlying receipts.
- Sealed Underlying Evidence. Bundled prior receipts (origination, implementation, FPIC, retirement) supporting the disclosure.
- Annual Refresh Yearbook. Year-over-year continuity of the disclosure claims.
- Multilingual Handover Packet to auditors and regulators. Drafted for the disclosing entity's audit and regulator-facing review.
Institutional version
A parallel set of artifacts for project portfolios, ICVCM and VCMI integrity assessments, corporate ESG departments, and the carbon-ratings agencies.
Aggregated attestation across project portfolios; population-level attestation for ICVCM, Voluntary Carbon Markets Integrity Initiative, and Article 6 supervisory body integrity assessments; integration with existing registry infrastructure. Target buyers: ICVCM and VCMI; project developers under buyer scrutiny; corporate ESG departments (Microsoft, Google, Stripe, Disney, the larger voluntary carbon buyers); insurance providers writing carbon liability coverage (Kita, Oka, Howden's climate desk); World Bank carbon finance arm; Green Climate Fund; regional development banks (AfDB, IDB, AsDB); indigenous-led organizations operating in REDD+ regions; the existing carbon-ratings agencies (Sylvera, Pachama, BeZero, Renoster — potentially as partners rather than competitors, since their satellite and statistical methods complement rather than replace human-witnessed attestation).
Same complement-not-replace disclaimer. PLENA Carbon & Climate Finance Attestation does not issue, validate, or retire carbon credits; does not measure emissions or sequestration; and does not replace third-party validators or verification bodies (DOEs, VVBs).
The 100-Year Operating Commitment
Adapted for a market whose claims are referenced in disclosure and liability proceedings decades after issuance.
PLENA Carbon & Climate Finance Attestation is built on the assumption that carbon credits issued today will be referenced in disclosure and liability proceedings decades from now, by which time many of today's registries, project developers, and verification bodies may no longer exist. Where actually implemented and populated, the intended architecture replicates each artifact produced here across multiple independent archives and anchors it cryptographically to public records that do not depend on the continued existence of any single registry or platform, and verifiable offline by anyone holding the cryptographic keys. Receipts survive registry restructuring, project developer insolvency, and the multi-decade lifetime of carbon liability claims.
Why this differs from carbon ratings and registry self-regulation
Carbon ratings agencies (Sylvera, Pachama, BeZero, Renoster, MSCI Carbon Markets) provide quantitative assessments of carbon credits and projects. Their work is largely satellite-driven and statistical, and is excellent for what it does. Registry self-regulation (Verra VCS, Gold Standard, ACR, CAR) validates projects against standards the registry itself sets. PLENA Carbon & Climate Finance Attestation is a third thing.
The differentiation is structural:
Human-witnessed attestation
Complementing satellite-based MRV, which has known blind spots — consent, benefit-sharing, displacement, partial implementation.
Community-controlled receipts
The project community holds its own attestation, not just the project developer.
Independence from any single registry
Receipts survive Verra or Gold Standard governance changes.
Multilingual by design
Critical for projects in non-English communities where existing documentation often is not.
PLENA Carbon & Climate Finance Attestation complements the carbon ratings agencies and the registries. The receipt layer is the layer none of them produces, and the layer that addresses the failures repeatedly identified in independent investigations of the market.

What this does not do
PLENA Carbon & Climate Finance Attestation does not issue, validate, or retire carbon credits. It does not measure emissions or sequestration. It does not replace third-party validators or verification bodies (DOEs, VVBs). It does not transfer credits or funds. It does not constitute carbon project advice. It does not adjudicate methodology disputes. It does not perform satellite monitoring or remote sensing. It does not represent any party before the registries, the supervisory bodies, or the regulators.
