GHG inventory · Engineering · TEE attestation
Verification is the new commodity.
Your GHG emissions inventory, decarbonization plan, technical memorandum, PDI or IHM can ship with a certificate, link and QR that an auditor, regulator or buyer checks in seconds, without depending on us. That is TEE attestation, optional: cryptographic proof of the document’s integrity and origin.
The thesis
AI takes care of production.
VERIDIS takes care of proof.
Reports, code, analysis, deliverables: artificial intelligence collapsed the cost of producing all of it. What became scarce is the opposite: proof of origin, faithful execution and accountability. That is why VERIDIS results can ship with a verification envelope: certificate, link and QR that any third party checks, without depending on us.
Services
What we deliver
Six objective fronts, all crossed by the same conducting thread: the result ships verifiable.
Data analysis
Proprietary corpus built on public energy, environment and climate data: multicriteria analysis, sector benchmarking and probabilistic simulation to decide on evidence, not opinion.

Any document of value becomes a traceable, auditable asset: certificate, link and QR that third parties verify independently of the issuer. Proof of integrity, execution and date.

PDI review, abandonment cost and financial guarantees with a method published in a peer-reviewed journal and benchmarking of public projects.
talk about this Export · CBAMProof of emissions origin
For exporters under CBAM: embedded emissions calculated and sealed at the source, in the format the European verifier checks. Those who prove pay the actual value; those who do not, pay the default.
talk about thisWho it is for
Where proof is worth money
From the offshore platform to the public office: wherever Industry 4.0 needs to turn data into proof, there is a document of value waiting for verification.
Emissions reporting under CBAM
The embedded emissions figure becomes certificate cost at the European border. Those who prove the data origin pay the actual value; those who do not, pay the default.
who demands it: European importer and verifierPDI and decommissioning
Decommissioning programs and financial guarantees assessed with a multicriteria method, benchmarking of public projects and a verification trail.
who demands it: regulator and auditEmissions MRV
Monitoring, reporting and verification of GHG with TEE attestation: the model applied in our contract with the Court of Justice of the State of Rio Grande do Sul (TJRS).
who demands it: internal oversight and societyVerifiable technical memoranda
Distributed generation and energy projects with a technical memorandum that proves itself: a memorandum with TEE attestation has already been accepted by a utility.
who demands it: utility and agencyIHM under the Hong Kong Convention
Inventory of hazardous materials for ship recycling, bilingual and verifiable from shipyard to flag.
who demands it: flag, class and yardThe conducting thread
From raw data to portable proof, in five steps
This is the process: what happens to your document. Data goes in, the calculation runs in a trusted execution environment, and the result comes out sealed, registered and verifiable by anyone, anywhere, independently of the issuer.
Input data
Measurement, inventory, memorandum or manifest enter as declared input, with the origin trail preserved.
merkle_root(inputs)Calculation in the enclave
The algorithm runs in a trusted execution environment (TEE) and the code is measured: the hash of what ran is recorded in the proof. Change one line and verification fails.
execution attestationHash and trusted date
A cryptographic hash binds result, exact algorithm version and timestamp into a tamper-evident package, where any later change is detectable.
sha-256 + rfc 3161Public anchor
The seal is anchored in an immutable public registry: no one erases, no one backdates, no one omits.
distributed ledgerCert + link + QR
The client carries the proof: a certificate verifiable by any third party, without depending on our platform.
portable verificationHonest boundary
We do not attest that the input data is true: that is the accredited verifier's role, and we serve as their input, never their rival. What we attest is that, given the declared inputs, the calculation ran faithfully in measured code and the proof package is tamper-evident, datable and verifiable. That discipline is what makes proof count.
Confidentiality and LGPD
Your data comes in protected and leaves without exposure
An emissions inventory touches personal data: staff commuting, business travel, invoices. Handling it carefully is part of the method, not an appendix.
Minimization before delivery
Personal data is removed or anonymized before a file leaves, with the method declared file by file and no third-party authorship metadata.
A cryptographic digest for every file
The delivery package carries the SHA-256 digests of the files received and delivered. With attestation, the digest list itself is sealed, and a later change becomes detectable.
Confidentiality set in the contract
Confidentiality and data processing under Brazil’s data protection law (LGPD, Law 13,709/2018) set in the contract, with a duty to report any incident.
Verify without publishing
TEE attestation is optional. When used, checking it takes only the file and the certificate: the document does not have to be published anywhere.
Credentials
The filters we have already passed
The in-house technology has already passed the most demanding filters there are: public procurement, peer technical review and utility examination.
Born with a signed public contract
VERIDIS starts its operation as an ME company with a five-year contract with the Court of Justice of the State of Rio Grande do Sul (TJRS) for monitoring, reporting and verification of emissions. In the first cycle, the report was attested by TEE.
Approved at the largest energy event in the country
Technical paper on attestation and verification approved for ROG.e, the largest oil, gas and energy gathering in Brazil.
Published and applied method
Multicriteria analysis methodology published in a peer-reviewed journal, applied in the platforms in production.
Brazilian IP filed
A family of patents and software registrations filed with INPI to protect the attestation core and the analysis method.
Accepted by an energy utility
Distributed generation technical memorandum with TEE attestation approved by a power utility.
Technology
Four fronts, one standard of proof
Everything that leaves VERIDIS crosses the same verification thread. The technology changes across fronts; the standard of proof, never.
AI with execution receipt
Agents and models enter the industrial process accompanied by cryptographic proof that they executed the defined policy. We do not promise to explain the model: we deliver proof that it ran the rule.
- Agents applied to licensing, MRV and regulatory monitoring
- Attested execution receipt for every relevant run
- AI governance with probative anchoring
Blockchain in service of proof
Immutable public registry to guarantee trusted date and non-omission, no jargon and no token. Blockchain enters as the registry layer of the verification envelope, in service of proof.
- Public integrity and time anchors
- An audit trail that outlives our own platform
- Interoperable with timestamping and qualified signature
In-depth data analysis
Proprietary corpus built on public energy, environment and climate data, treated methodically: multicriteria analysis, sector benchmarking and probabilistic simulation.
- Multicriteria methodology published in a peer-reviewed journal
- Benchmark of dozens of public decommissioning projects
- Monte Carlo simulation for risk and regulatory scenarios
The conducting thread of truthfulness
Trusted execution environment available for deliverables: the record stands as auditable, portable proof. It is the backbone of the firm, protected by Brazilian Intellectual Property.
- Certificate, link and QR verifiable by third parties, independently of the issuer
- Applicable to any document of value: GHG, PDI, IHM, memoranda
- Family of patents and software registrations filed with INPI
Open architecture
The verification envelope, no black box
If the thread is the process, the envelope is the anatomy of proof: what each layer guarantees, and before whom. The prover is pluggable: today the strongest layer is TEE attestation; if a stronger proof emerges tomorrow, the envelope incorporates it without changing the certificate format.
