The Price of Sovereignty Dr. Vincent Adams on the ExxonMobil Parent Company Guarantee and the Risks Guyana Quietly Carries

Webinars

Dr. Vincent Adams argues that Guyana’s current financial backstop for oil spills is woefully inadequate, leaving the nation exposed to catastrophic risks.

By Guyana Business Journal · May 25, 2026

Speaking days after the Court of Appeal struck down the 2023 Kissoon ruling, Dr. Vincent Adams—the regulator who personally negotiated the disputed clauses—argued that the decision leaves Guyana protected by a financial backstop he considers a fraction of what a real spill would cost. His central claim is that the much-debated word “unlimited” was never the point: the permit says the parent companies must cover “all costs” above insurance if the local subsidiary fails to pay, and “all” already means what it says.

1. What the Ruling Did — and the $2 Billion Question

On May 7, 2026, three Court of Appeal justices unanimously overturned Justice Sandil Kissoon’s 2023 decision, which had read the Liza Phase 1 permit as requiring an unlimited parent company guarantee. What remains, Adams noted, is an arrangement resting on a roughly $2 billion assurance figure alongside a claimed $600 million insurance policy—numbers he called wholly inadequate to a catastrophic spill, and which he says no one has ever been allowed to independently verify.

Adams traced the figure’s origin to a 2019 exchange in which the operator presented London insurance paperwork totaling about $2 billion. He says he rejected it as inadequate and demanded that ExxonMobil’s parent entity provide a guarantee to cover anything above what EMGL and their insurance would provide, which, he notes, cost the company nothing, since it was a guarantee rather than a purchased policy.  This guarantee was, as Adams explained, enshrined in, and agreed to, the operating permit signed by ExxonMobil. The $2 billion ceiling, on his account, then reappeared after the Kissoon case as a permit amendment requiring the sum to be set by “estimate,” without removing the original “all costs” language.

GBJ Data Note: The estimated financial assurance for an oil spill in Guyana is roughly $2 billion, which Dr. Adams considers wholly inadequate compared to the $145 billion cost of the Deepwater Horizon disaster.

“This fictitious cap of $2 billion to clean up an oil spill — an oil spill does not cost $2 billion. It’s a drop in the ocean.”

2. Why the Guarantee is the Only Instrument that Reaches Exxon

The heart of Adams’s argument is structural. Every contract, permit, and authorization in Guyana, he said, is signed not by ExxonMobil but by EMGL—a subsidiary he describes as deliberately created to insulate the parent from liability, holding effectively no recoverable assets. ExxonMobil’s name, he stressed repeatedly, appears on none of the documents.

He dismissed the government’s suggestion that Guyana could simply seize EMGL’s assets, pointing out that under the Production Sharing Agreement, the movable and fixed assets revert to the state on termination anyway—meaning, in a disaster, Guyana would be “seizing our own assets” with no market to sell them into. The parent company guarantee, he argued, is the single instrument that pierces this structure and reaches the parent’s balance sheet; the rest of the framework stops at a subsidiary that can simply declare bankruptcy.

To the common objection that such guarantees are rare internationally, Adams turned the point around: the guarantee is unusual because Guyana’s arrangement is unusual. In the United States, he noted, a company cannot interpose an asset-light subsidiary to run a high-hazard operation in the first place—so the guarantee is unnecessary there precisely because the parent is already on the hook. He cited Shell’s defense in Nigerian spill litigation—that liability belonged to its subsidiary, not the parent—as exactly the outcome the guarantee is meant to prevent. He also cited the Macondo spill, where BP’s name, not a subsidiary’s, was on the operating documents, and, as such, necessitated BP’s coverage of the resulting liability. 

“Exxon, the big company with the deep pocket — they’re invisible. This child company that Exxon formed for the single reason to insulate Exxon from any liability — that’s who signs the agreement, signs the permits.”

3. “All” Means All: The Language of Clauses 14.1 and 14.10

Adams stated that he personally inserted the operative words. Clause 14.1, in his telling, requires the permit holder to obtain insurance without specifying an amount; clause 14.10 then provides that if the permittee (EMGL) fails to cover liabilities, the parent, affiliates, and co-venturers must cover all damages above the insurance, whatever its size.

On this reading, the public framing of “unlimited” was a distraction—a word that appears nowhere in the document but became the battleground anyway. Both Adams and host Terrence Blackman returned to the plainness of the contractual term: if a contract says “all,” a party cannot later decide that “all” means whatever an estimate produces. Adams added that the only defensible way to estimate catastrophic exposure is to look at the nearest analogue—and the analogue is Macondo.

“I put in the word ‘all,’ and I put in ‘if EMGL fails to do so.’ Those are the keywords — ‘fails to do so,’ and ‘all.'”

4. The Capping Stack: A Safeguard Tripled in the Wrong Direction

Among the report’s most striking revelations was Adams’s account of the capping stack—the heavy subsea cap (50–150 tons) used to seal a blown-out well, the very tool the world watched deployed during Macondo. The single most important factor, he said, is how fast it can reach the site.

On his account, the operator first proposed a 20-day mobilization window. He and Dr. Mark Bynoe, the former Head of the Department of Energy, rejected it, negotiated it down to five days, and wrote into the Payara permit a requirement to submit a plan to reach three days, with the equipment staged from South Trinidad, the only location from which those timelines were achievable. After the 2020 change of administration, he said, the Payara permit was amended: the window was tripled to 9 days, and the equipment was relocated to a shore base in Guyana.

Adams also questioned who now maintains the equipment, what their qualifications are, and whether any independent body verifies its readiness, noting that oversight of capping-stack readiness operates on a subscription model with no routine external inspection.

“They tripled the time from three to nine days — which means an extra six days of oil gushing into the ocean. And then they bragged that they improved the environmental requirements. That is nonsense.”

5. Beyond the Guarantee: Limits, Flaring, and Produced Water

The conversation widened into a broader critique of how the operation is run against its own Environmental Impact Assessment, which Adams emphasized carries the force of law once approved. He alleged a consistent pattern of operating beyond the parameters the EIA sets:

• Production limits: For Liza Phase 1, he said the EIA set a safe operating limit of 120,000 barrels/day and an internal control of 100,000 barrels/day—yet production reached 165,000 barrels/day, well above the legal ceiling, with similar overruns on other projects.
• Flaring: A strict prohibition, he says, was in place and was replaced with a fee allowing effectively unlimited flaring—”turning environmental control on its head.”
• Produced water: Rather than reinjecting the produced water — contaminated, radioactive, and 2 to 3 times the temperature of the surrounding ocean, currently running at roughly 170,000 barrels a day — he alleged it is discharged straight into the sea. Meanwhile, he said, about 1,000,000 barrels of seawater are drawn in daily, pulling in millions of fish eggs, under permits that allow a set quantity of residual oil per volume discharged.
• Consultant Report: A 2020 report by Government Consultant, Allison Redford, which he says recommended reinjection and an end to flaring, has, in his account, never been released.

Adams argued that raising production above the EIA limit is not a paperwork matter but a direct increase in the probability of catastrophe—paired, in his view, with a simultaneous refusal to underwrite the consequences.

6. A Regional Risk with No Regional Seat at the Table

Citing the EIA’s own spill-trajectory modeling, Adams said a major Stabroek-area spill would not principally strike Guyana. The plume travels west, northwest, and southwest: Trinidad’s entire eastern shore would be hit first, Venezuela’s coast among the worst affected, with the modeled reach extending as far as Jamaica. He noted the recent Venezuela–Trinidad friction over a comparatively tiny spill as a preview of the diplomatic stakes.

Because an EIA is, by definition, an assessment of who is impacted, Adams said he had intended while at the EPA to bring every island in the spill pathway into the EIA development and the response planning—work he says was never taken up, and which CARICOM has not pursued. For island economies built on fishing and tourism, he warned, the consequences could be existential.

“Every day there is a ship that travels from Guyana through the Caribbean with approximately million barrels. Just imagine if one of those runs aground. It may not even happen in Guyana’s waters.”

7. The Oversight That Never Arrived

Perhaps the quietest but most consequential thread was capacity. Adams described securing World Bank funding to build a 36-member petroleum unit inside the EPA—experienced specialists who would be stationed aboard the FPSOs around the clock, with living quarters Exxon had agreed to provide—plus a study-leave program and a university petroleum-engineering pipeline. None of it, he said, survived. By his account, the EPA today has no staff member with even an hour of formal petroleum training.

He also described the corporate geography behind the operation: the contracting entity is incorporated in the Bahamas rather than Guyana, with a web of related companies running through the Netherlands, and a tax arrangement in which, he alleged, Guyana effectively pays the operators’ taxes and issues receipts the companies are allegedly using for tax benefits abroad.

“Whatever Exxon comes and tells us, that’s what we accept — because we have no ability to ask questions.”

8. Where It Goes From Here

Adams expressed hope that the matter reaches the Caribbean Court of Justice on the right question—not the red herring of “unlimited insurance,” but the plain meaning of “all costs” and the unanswered question the appellate ruling leaves open: who pays for anything above $2 billion? He pointed to Justice Kissoon’s ruling as the most thorough treatment of the issues and urged it be read widely. He criticized the government’s decision to appeal Judge Kissoon’s ruling favoring Guyana and to go all the way to the CCJ to seek authority to join ExxonMobil in the appeal, as difficult to understand on anything other than political grounds.

Both speakers framed the stakes morally as well as legally: a lopsided arrangement in which the operator profits enormously while the host state would absorb the cost of catastrophe from its still-modest sovereign savings. As Adams put it, the guardrails already existed, cost the company nothing, and were given away.

“If something happens, every dime that we have accumulated will be gone — and the loans, and everything, still has to be paid.”
