With Guyana preparing to celebrate its 60th Independence anniversary on May 26, a fierce national debate has erupted over sovereignty, environmental protection and the country’s ability to hold multinational oil companies accountable after the Court of Appeal overturned a landmark ruling requiring ExxonMobil to provide unlimited coverage for oil spill damages.
Last week, the Court of Appeal reversed a 2023 High Court decision by Justice Sandil Kissoon that had ordered ExxonMobil Guyana Limited (EMGL) to secure an unlimited parent company guarantee from ExxonMobil Corporation and its Stabroek Block partners, Hess and CNOOC, to cover the costs of any offshore oil spill.
The appellate court ruled that while Exxon remains liable for pollution-related damages, Guyana’s environmental permits and laws do not explicitly require unlimited financial assurance, and that the Environmental Protection Agency (EPA) has the discretion to determine the level of coverage required. The matter is expected to be appealed to the Caribbean Court of Justice.
The ruling has drawn fierce criticism from former EPA Executive Director Dr. Vincent Adams, who said the decision leaves Guyana dangerously exposed to financial and environmental catastrophe while effectively insulating ExxonMobil from full liability.
Dr. Adams, an energy expert and former senior manager at the United States Department of Energy, said he “hands down” disagrees with the Court’s overturning of Justice Kissoon’s decision, describing the original ruling as a critical safeguard for Guyana.
“As the Environmental Protection Agency (EPA) Head who created the PCG policy as the only necessary means to protect Guyana’s interest, with all due respect to the Court, I hands down disagree with its overturning of Kissoon’s profoundly thorough understanding of the context and well thought out Decision,” Adams wrote in a public letter.
He warned that Guyana’s founding leaders “must be turning in their graves witnessing the surrendering of Guyana’s sovereignty to new colonial masters such as corporate giant Exxon.”
The case centers on whether ExxonMobil’s parent company should bear full responsibility for the potentially enormous costs associated with a catastrophic offshore oil spill.
Justice Kissoon’s original ruling was widely viewed by environmental advocates and petroleum policy observers as a major step toward stronger accountability in Guyana’s rapidly expanding oil sector. The judge had ruled that the EPA unlawfully failed to enforce permit provisions requiring full parent company guarantees.
Adams argued that the Court of Appeal ignored the clear language contained in the permits themselves.
He cited Clause 14:1, which states that EMGL “is liable for all costs associated with” an oil spill, and Clause 14:10, which requires parent companies and co-venturers to provide legally binding agreements to meet those obligations if EMGL “fail to do so.”
“It is therefore unfathomable how such ‘unambiguous language’ could mean anything but an ‘unlimited guarantee’, since all means no limit,” Adams stated.
He warned that ExxonMobil Guyana Limited, the local subsidiary named in the permits, does not possess sufficient assets to independently cover a catastrophic spill.
“Consequently, in the event of a spill, EMGL declares bankruptcy and Exxon goes scot-free, leaving Guyana holding the bag of financial bankruptcy and environmental catastrophe,” he wrote.
Guyana’s oil sector has expanded rapidly since first production in December 2019, transforming the country into one of the world’s fastest-growing oil producers. ExxonMobil currently operates multiple offshore projects in the Stabroek Block alongside Hess and CNOOC, with production continuing to rise.
Environmental advocates, petroleum analysts and sections of civil society have repeatedly warned that Guyana’s environmental safeguards remain weak compared with more established oil-producing nations.
Adams argued that Exxon would never be allowed to operate under similar liability arrangements in the United States.
“Exxon would never get away with such a scheme in its home country of the USA,” he asserted, while referencing Justice Kissoon’s earlier criticism that EMGL was benefiting from “the omissions of a derelict, pliant and submissive EPA.”
A central issue in the case is Exxon’s existing US$2 billion insurance and financial assurance package. Adams dismissed the suggestion that potential damages from a major spill could be realistically estimated or capped.
He pointed to the 2010 Deepwater Horizon disaster in the Gulf of Mexico, which spilled roughly five million barrels of oil over 87 days and ultimately cost BP approximately US$145 billion.
“Whosoever could do such an estimate has to be a fortune teller and should immediately purchase a lottery ticket,” Adams wrote.
The former EPA head also accused the PPP/C administration of siding with Exxon after returning to office in 2020. According to Adams, Exxon had previously agreed to the parent company guarantee language contained in permits issued beginning in 2019.
The case itself was brought by citizens Frederick Collins and Godfrey Whyte, who argued that Guyana could face devastating consequences if Exxon’s parent company is not legally bound to absorb the full costs of a major spill.
Adams further warned that the country is already confronting mounting environmental risks from offshore operations, accusing Exxon of discharging toxic produced water into the Atlantic Ocean, excessive gas flaring and producing above limits outlined in the Environmental Impact Assessment.
At its core, the dispute has become far bigger than a legal battle over permit language. It now raises profound questions about whether Guyana, amid unprecedented oil wealth, will assert sovereign control over its natural resources or permit foreign oil corporations to operate under protections unavailable in their own jurisdictions.
The outcome may ultimately define whether the country’s oil boom becomes a foundation for national development or a cautionary tale of wealth extraction paired with environmental vulnerability and weakened state authority.
