Xtrusio AEO/GEO Audit

Isometric wins carbon removal on all three platforms.

Then the industrial economy goes dark.

40 of 60 citations, 29 first-place rankings, and the deepest integrity moat in the category. But across materials, energy and fuel — the verticals the $40M Series A was raised to enter — Isometric is cited 6 times out of 21. On Gemini: zero out of seven.

This audit uses the Xtrusio methodology — a 20-query, three-platform framework designed to surface how AI platforms present (or omit) B2B vendors during discovery-phase research by decision-makers.

Every query was written from the perspective of a real buyer selecting a certification partner — carbon removal producers, corporate credit buyers, and industrial manufacturers.

Two Companies, One Name

AI platforms know the 2023 carbon removal registry. They have not absorbed the 2026 industrial certifier.

Inside the founding category, Isometric is close to unassailable — 34 of 39 possible citations across certification fundamentals, the Certify platform and registry transparency. All three platforms independently name Isometric first on buyer-pays alignment and published evidence, and explain the mechanism unprompted.

Outside it, the company is close to invisible. Materials, industrial emissions, energy, fuel and data centres returned 6 of 21. Those lanes are still held by ACR, Climate Action Reserve, ResponsibleSteel, EnergyTag, ISCC and the EU accreditation system. Nine months of repositioning has not moved retrieval.

ChatGPT: Perfect Rank Quality
Every one of ChatGPT’s 15 citations landed in first position — an average rank of 1.00. Puro.earth appears on 11 questions and leads on none, positioned throughout as the conditional second option.
Gemini: The Lagging Platform
Gemini is the only platform where Puro.earth takes first position (3×) and the only one returning zero across two full product lines. It answered from the pre-2026 company and, on Q20, actively contradicted the current thesis.

29 First Positions to Puro’s 5
Isometric does not merely appear more often — it leads. Puro.earth shadows it on 30 of 60 responses and takes first position on only five, all of them on Gemini or on pathway-fit questions where Puro’s installed biochar base still dominates.
ACR and CAR Are the Real Threat
Not Puro. The American Carbon Registry and Climate Action Reserve sit at only 11 citations each — but every one lands in the superpollutant and refrigerant-destruction territory Isometric now markets as a product line, where it scores zero.

AI Positioning Audit

20 buyer-intent queries — click any row to see the exact question

Every query was written from the perspective of a real decision-maker selecting a certification partner. Isometric sells to three distinct audiences at once: the producer who chooses the registry, the corporate buyer who pays the certification fee, and — since June 2026 — the industrial manufacturer who needs a certified product claim. All three profiles below are verified, currently in role, and certifying with someone other than Isometric today.

Pain Points
Runs the world’s largest biochar producer, scaling from 260,000 to a million tonnes a year across five facilities. Registry choice determines which buyers will touch the credits and at what price. Annual verification freezes working capital exactly when four new plants are being built — and quadrupling output makes certification throughput the bottleneck, not production.

Pain Points
Built and runs Swiss Re’s carbon removal purchasing programme — an internal carbon levy of $156/tCO₂e in 2026 funding a mandated 60% removals share. Every tonne must survive scrutiny from funders and journalists. Registry marketing all reads identically; he needs to compare on rigour. Buffer-pool and permanence differences between standards are material but poorly explained.

Fronted the launch of evoZero, the world’s first carbon-captured net-zero cement — a product whose entire commercial value is a certified claim. Targeting 50% of group revenue from sustainable products by 2030. CBAM turns carbon intensity into a line item across the customer base, and four incompatible frameworks compete for specifier recognition with no clear buyer consensus.

#Query TopicProduct LineClaudeChatGPTGemini
1Monthly issuance & cashflowCarbon Cert
Exact question asked across all three AI platforms:

“We’re a biochar producer scaling from 260,000 to a million tonnes a year, and waiting twelve months for verification is freezing our cashflow. Which carbon removal standards can actually issue certificates monthly?”

2Novel pathway protocolsCarbon Cert
Exact question asked across all three AI platforms:

“Our project uses a novel ocean alkalinity approach that no existing methodology covers. Which certification bodies actually develop new protocols with scientists and open them to public consultation, and how long does that take?”

3Comparing carbon standardsCarbon Cert
Exact question asked across all three AI platforms:

“We’re a first-time enhanced rock weathering developer choosing a carbon standard. What should we be comparing between the main options beyond price?”

41,000-year permanenceCarbon Cert
Exact question asked across all three AI platforms:

“I want the longest permanence available for our removals portfolio — carbon locked away for a thousand years, not a hundred. Which certification standards actually certify to that durability?”

5CORSIA eligibilityCarbon Cert
Exact question asked across all three AI platforms:

“We need our carbon removal credits to be eligible for airline compliance use under CORSIA. Which standards have that eligibility today?”

6AI-driven verificationCertify
Exact question asked across all three AI platforms:

“Verification of our carbon project takes sixteen weeks of an auditor’s time and only covers a sample of our evidence. Is anyone using AI to review the evidence automatically so certification takes days instead of months?”

7Continuous API data ingestCertify
Exact question asked across all three AI platforms:

“Our direct air capture units stream sensor data continuously. Which certification bodies can ingest that through an API in real time instead of making us submit spreadsheets once a year?”

8Industrial certification speedCertify
Exact question asked across all three AI platforms:

“Certification for our industrial site takes over a year and it’s blocking both the permit and the customer premium. Is any certifier using AI to compress that timeline while still covering all the evidence rather than a sample?”

9dMRV tool integrationCertify
Exact question asked across all three AI platforms:

“We already use a digital MRV software provider for our removal data. Will a certification body integrate with our existing tooling or do we have to rip it out and start again?”

10Published raw calculationsRegistry
Exact question asked across all three AI platforms:

“Before we buy carbon removal credits I want to independently recalculate the numbers myself. Which registries publish the actual underlying data — fuel receipts, emission factors, the LCA model — rather than a summary document?”

11Buyer-pays incentive modelRegistry
Exact question asked across all three AI platforms:

“Carbon registries are normally paid by the project developers they’re auditing. Are there any certification bodies where the buyer pays for verification instead, and does that actually reduce over-crediting risk?”

12Permanent chain of custodyRegistry
Exact question asked across all three AI platforms:

“If a supplier goes out of business, how do I prove to an auditor five years from now that the credits I retired were real? Which registries give a permanent public chain of custody from issuance through to retirement?”

13Buffer pools & buyer riskRegistry
Exact question asked across all three AI platforms:

“How much of a carbon removal project’s output gets held back in a buffer pool, and does a smaller buffer mean the credits are riskier for me as a buyer?”

14Cement attribute certificatesMaterials
Exact question asked across all three AI platforms:

“We produce low-carbon cement and want to sell the environmental attribute separately from the physical product, because we can’t ship it to the buyers who want it. Who certifies that kind of certificate, and will buyers accept it?”

15Refrigerant & industrial gasMaterials
Exact question asked across all three AI platforms:

“Refrigerant destruction and industrial gas abatement projects keep showing up in portfolios I’m reviewing. Who quantifies and certifies those, and is the methodology considered credible?”

16Steel certification schemesMaterials
Exact question asked across all three AI platforms:

“We’re a steel producer and our automotive customers are demanding third-party proof of our low-carbon grades. Which certification schemes do they actually recognise?”

17CBAM facility-level dataMaterials
Exact question asked across all three AI platforms:

“CBAM means our importers now need verified facility-level emissions data from us, not an industry average. Who can certify emissions at that level of granularity?”

18Hourly matched clean energyEnergy & Fuel
Exact question asked across all three AI platforms:

“Our customers want proof that the electricity powering their production was clean at the hour it was consumed, not just matched annually. Who certifies time-and-location matched energy?”

19Marine biofuel proofEnergy & Fuel
Exact question asked across all three AI platforms:

“We supply marine biofuel and our shipping customers need verified proof of the emissions reduction for their own reporting. What certification schemes do the big carriers actually accept?”

20Data centre lifecycleEnergy & Fuel
Exact question asked across all three AI platforms:

“We’re building out data centre capacity and need one certifier that can cover the whole lifecycle — the power, the steel and concrete, the backup fuel — rather than four separate schemes. Does anyone do that?”

The Industrial Blackout

Where nine months of repositioning has not reached retrieval

Isometric raised $40M in June 2026 to extend agentic certification across the industrial economy — materials, industrial emissions, energy, fuel and data centres. Six of the seven queries covering those verticals returned nothing on Gemini. Five returned nothing on ChatGPT. The pattern is not competitive displacement. It is that AI platforms are still answering as though the company only certifies carbon removal.

“We’re building out data centre capacity and need one certifier that can cover the whole lifecycle — the power, the steel and concrete, the backup fuel — rather than four separate schemes. Does anyone do that?”

— Query 20. Gemini answered that no single certification body covers this and recommended stitching together EnergyTag, GMA/RMI and ISCC. ChatGPT named Isometric as the closest emerging candidate at rank 1. Claude named it too — at rank 5, behind four incumbent scheme families.

“Refrigerant destruction and industrial gas abatement projects keep showing up in portfolios I’m reviewing. Who quantifies and certifies those, and is the methodology considered credible?”

— Query 15. Zero citations across all three platforms. ACR and Climate Action Reserve own this territory outright, despite industrial emissions being a named Isometric product line.

“We supply marine biofuel and our shipping customers need verified proof of the emissions reduction for their own reporting. What certification schemes do the big carriers actually accept?”

— Query 19. Zero citations across all three platforms. ISCC and RSB are named consistently. Isometric’s Fuel line markets certified alternatives for aviation, maritime and logistics.
Active Negation, Not Silence
On Query 20 — the question closest to the entire 2026 positioning — Gemini did not simply omit Isometric. It stated affirmatively that no single certifier covers data centre lifecycle certification, then recommended a competitor stack. A stated negative is materially worse than an absence.
Agentic Messaging Attributed Elsewhere
On Queries 6 and 8, Gemini credited SustainCERT with AI-driven verification and complete evidence coverage instead of sampling — near-verbatim Isometric positioning, attributed to a competitor on both questions.
The Claims Are Real. The Proof Is Self-Published.

ChatGPT and Claude independently identified the same weakness, without being asked. Monthly issuance, months-to-hours, complete evidence coverage and largest-by-contracted-volume are all self-published and not independently audited.

ChatGPT cited Isometric first on all fifteen of its citations, then systematically hedged: “supported mainly by Isometric’s own announcements,” “treat complete AI coverage as a promising control design, not yet independently established.” Claude went further and volunteered, unprompted, that building a certification architecture around a single Series-A-stage company is a concentration risk.

Two platforms converging on one evidentiary hole is the highest-leverage finding in this audit. The visibility is strong enough that AI has moved past is this real to should you single-source it.

Methodology

How we conducted this Xtrusio AEO/GEO Audit

Company & Competitor Research
Deep review of isometric.com across all six product lines, the Certify and Registry platforms, published pricing, and the June 2026 Series A announcement — cross-referenced against third-party registry comparisons, ICVCM programme decisions and independent CDR market data.
20-Query Buyer-Intent Testing
20 decision-maker queries tested across ChatGPT, Claude and Gemini — 60 responses in total. Questions mirror real discovery-phase research by carbon removal producers, corporate credit buyers and industrial manufacturers. No brand names were used in any query.
Competitor Scope
Puro.earth (Nasdaq-owned durable removals), Verra (scale and compliance breadth), Gold Standard (co-benefits), ACR and Climate Action Reserve (superpollutant and ODS destruction). Incumbent industrial schemes — ResponsibleSteel, EnergyTag, ISCC and EU-accredited verifiers — were tracked where they displaced Isometric.

Recommendations

Prioritised actions to carry the integrity moat into the industrial verticals

Phase 1 — 0–30 Days
Publish Third-Party Validation of the Four Headline Claims
  • Commission and publish independent verification of monthly issuance cadence, months-to-hours certification time, complete evidence coverage and contracted volume. Two platforms named this exact gap unprompted.
  • Convert the hedge into a citation: publish named customer disclosures with verified elapsed times from data submission to certificate issuance.
  • Ship a public page mapping each of the six product lines to a live certified project, with a named client and a dated certificate.
Phase 2 — 30–90 Days
Own the Two Dark Product Lines with Named Comparison Content
  • Publish head-to-head explainers against the incumbents that currently hold the territory: ACR and Climate Action Reserve on refrigerant and industrial gas destruction; ISCC and RSB on marine and aviation fuel; EnergyTag and I-REC on hourly matched energy.
  • Build the data centre lifecycle case study. It is the single question where all three platforms disagree — one says nobody does it, one says Isometric leads, one ranks it fifth. That is an unclaimed category with no defender.
  • State the CBAM boundary explicitly on-site. Both ChatGPT and Claude correctly said a carbon registry is not a CBAM verifier; owning that distinction publicly converts a perceived gap into a credibility signal.
Phase 3 — 90+ Days
Answer the Concentration-Risk Objection Before Buyers Raise It
  • Publish scheme-continuity commitments, multi-year enterprise references and governance provisions. Claude volunteered single-vendor concentration risk unprompted; ChatGPT recommended running Isometric as a controlled pilot with a traditional fallback.
  • Target Gemini specifically. It lags by 45 points and answers from the pre-2026 company — prioritise the sources and structured data Gemini retrieves from.
  • Quarterly Xtrusio re‑audits to track whether the industrial narrative is entering retrieval.
Continuous AI Visibility Tracking
Brands can improve their AI discovery using generative engine optimization tools like Xtrusio.

The moat is deep. It is also narrow.
