Big Oil and Gas kept a dirty secret for decades. Now they may pay the price

The environmentalist Bill McKibben once characterized the fossil fuel industry’s behavior as "the most consequential cover-up in US history." And now for the first time in decades, the lawsuits chart a path toward public accountability that climate activists say has the potential to rival big tobacco's downfall after it concealed the real dangers of smoking.

"We are at an inflection point," said Daniel Farber, a law professor at the University of California, Berkeley and director of the Center for Law, Energy, and the Environment.

"Things have to get worse for the oil companies," he added. "Even if they've got a pretty good chance of winning the litigation in places, the discovery of pretty clear-cut wrong doing — that they knew their product was bad and they were lying to the public — really weakens the industry's ability to resist legislation and settlements."

For decades, the country's leading oil and gas companies have understood the science of climate change and the dangers posed by fossil fuels. Year after year, top executives heard it from their own scientists whose warnings were explicit and often dire.

In 1979, an Exxon study said that burning fossil fuels "will cause dramatic environmental effects" in the coming decades.

"The potential problem is great and urgent," it concluded.

But instead of heeding the evidence of the research they were funding, major oil firms worked together to bury the findings and manufacture a counter narrative to undermine the growing scientific consensus around climate science. The fossil fuel industry’s campaign to create uncertainty paid off for decades by muddying public understanding of the growing dangers from global heating and stalling political action.

The urgency of the crisis is not in doubt. A draft United Nations report, leaked last week, warns that the consequences of the climate crisis, including rising seas, intense heat and ecosystem collapse, will fundamentally reshape life on earth in the coming decades even if fossil fuel emissions are curbed.

To investigate the lengths of the oil and gas industry’s deceptions — and the disastrous consequences for communities across the country — the Guardian is launching a year-long series tracking the unprecedented efforts to hold the fossil fuel industry to account.

The legal process is expected to take years. Cities in California filed the first lawsuits back in 2017, and they have been tied down by disputes over jurisdiction, with the oil companies fighting with limited success to get them moved from state to federal courts where they think the law is more favorable.

But climate activists see opportunities long before verdicts are rendered in the U.S. The legal process is expected to add to already damning revelations of the energy giants’ closely-held secrets. If history is a guide, those developments could in turn alter public opinion in favor of regulations that the oil and gas companies spent years fighting off.

A string of other recent victories for climate activists already points to a shift in the industry's power. 

Last month, a Dutch court ordered Shell to cut its global carbon emissions by 45% by the end of the decade. The same day, in Houston, an activist hedge fund forced three new directors onto the board of the U.S.'s largest oil firm, ExxonMobil, to address climate issues. Investors at Chevron also voted to cut emissions from the petroleum products it sells.

Earlier this month, developers of the Keystone XL pipeline cancelled the project after more than a decade of unrelenting opposition over environmental concerns. And although a federal court last year threw out a lawsuit brought by 21 young Americans who say the US government violated their constitutional rights by exacerbating climate change, the Biden administration recently agreed to settlement talks in a symbolic gesture aimed to appease younger voters.

For all that, American lawyers say the legal reasoning behind foreign court judgements are unlikely to carry much sway in the U.S. and domestic law is largely untested. In 2018, a federal court knocked back New York City's initial attempt to force Big Oil to cover the costs of the climate crisis by saying that its global nature requires a political, not legal, remedy.

Other regional lawsuits are inching their way through the courts. From Charleston, South Carolina, to Boulder, Colorado, and Maui, Hawaii, communities are seeking to force the industry to use its huge profits to pay for the damage and to oblige energy companies to treat the climate crisis for what it is — a global emergency.

Municipalities such as Imperial Beach, California — the poorest city in San Diego county with a budget less than Exxon chief executive’s annual pay — faces rising waters on three sides without the necessary funding to build protective barriers. They claim oil companies created a "public nuisance" by fuelling the climate crisis. They seek to recover the cost of repairing the damage and constructing defences.

The public nuisance claim, also pursued by Honolulu, San Francisco, and Rhode Island, follows a legal strategy with a record of success in other types of litigation. In 2019, Oklahoma's attorney general won compensation of nearly half a billion dollars against the pharmaceutical giant Johnson & Johnson over its false marketing of powerful prescription painkillers on the grounds it created a public nuisance by contributing to the opioid epidemic in the state.

Other climate lawsuits, including one filed in Minnesota, allege the oil firms' campaigns of deception and denial about the climate crisis amount to fraud. Minnesota is suing Exxon, Koch Industries, and an industry trade group for breaches of state law for deceptive trade practices, false advertising, and consumer fraud over what the lawsuit characterises as distortions and lies about climate science.

The midwestern state, which has seen temperatures rise faster than the U.S. and global averages, said scorching temperatures and "mega-rains" have devastated farming and flooded people out of their homes, with low income and minority families most at risk.

Minnesota's attorney general, Keith Ellison, claims in his lawsuit that for years Exxon orchestrated a campaign to bury the evidence of environmental damage caused by burning fossil fuels "with disturbing success."

"Defendants spent millions on advertising and public relations because they understood that an accurate understanding of climate change would affect their ability to continue to earn profits by conducting business as usual," Ellison said in his lawsuit.

Farber said cases rooted in claims that the petroleum industry lied have the most promising chance of success.

"To the extent the plaintiffs can point to misconduct, like telling everybody there’s no such thing as climate change when your scientists have told you the opposite, that might give the courts a greater feeling of comfort that they're not trying to take over the U.S. energy system," he said.

Fighting the facts 

Almost all the lawsuits draw on the oil industry's own records as the foundation for claims that it covered up the growing threat to life caused by its products.

Shell, like other oil companies, had decades to prepare for those consequences after it was forewarned by its own research. In 1958, one of its executives, Charles Jones, presented a paper to the industry's trade group, the American Petroleum Institute (API), warning about increased carbon emissions from car exhaust. Other research followed through the 1960s, leading a White House advisory committee to express concern at "measurable and perhaps marked changes in climate" by the year 2000.

API's own reports flagged up "significant temperature changes" by the end of the twentieth century.

The largest oil company in the U.S., Exxon, was hearing the same from its researchers.

Year after year, Exxon scientists recorded the evidence about the dangers of burning fossil fuels. In 1978, its science advisor, James Black, warned that there was a "window of five to ten years before the need for hard decisions regarding changes in energy strategy might become critical." 

Exxon set up equipment on a supertanker, the Esso Atlantic, to monitor carbon dioxide in seawater and the air. In 1982, the company's scientists drew up a graph accurately plotting an increase in the globe’s temperature to date.

"The 1980s revealed an established consensus among scientists," the Minnesota lawsuit against Exxon says. "A 1982 internal Exxon document … explicitly declares that the science was 'unanimous' and that climate change would 'bring about significant changes in the earth's climate.' "

Then the monitoring on the Esso Atlantic was suddenly called off and other research downgraded.

What followed was what Naomi Oreskes, co-author of the report America Misled, called a "systematic, organised campaign by Exxon and other oil companies to sow doubt about the science and prevent meaningful action."

The report accused the energy companies of not only polluting the air but also "the information landscape" by replicating the cigarette makers' playbook of cherry picking data, using fake experts, and promoting conspiracy theories to attack a growing scientific consensus.

Many of the lawsuits draw on a raft of Exxon documents held at the University of Texas, and uncovered by Columbia University and the Los Angeles Times in 2015.

Among them is a 1988 Exxon memo laying out a strategy to push for a "balanced scientific approach," which meant giving equal weight to hard evidence and climate change denialism. That move bore fruit in parts of the media into the 2000s as the oil industry repositioned global heating as theory, not fact, contributing to the most deep-rooted climate denialism in any developed country.

The company placed advertisements in major American newspapers to sow doubt. One in The New York Times in 2000, under the headline "Unsettled Science," compared climate data to changing weather forecasts. It claimed scientists were divided, when an overwhelming consensus already backed the evidence of a growing climate crisis, and said that the supposed doubts meant it was too soon to act.

Exxon's chairman and chief executive, Lee Raymond, told industry executives in 1996 that "scientific evidence remains inconclusive as to whether human activities affect global climate."

"It's a long and dangerous leap to conclude that we should, therefore, cut fossil fuel use," he said.

Documents show that his company's scientists were telling Exxon's management that the real danger lay in the failure to do exactly that.

In 2019, Martin Hoffert, a professor of physics at New York University, told a congressional hearing that as a consultant to Exxon on climate modelling in the 1980s, he worked on eight scientific papers for the company that showed fossil fuel burning was "increasingly having a perceptible influence on earth’s climate." 

Hoffert said he "hoped that the work would help to persuade Exxon to invest in developing energy solutions the world needed." That was not the result.

"Exxon was publicly promoting views that its own scientists knew were wrong, and we knew that because we were the major group working on this. This was immoral and has greatly set back efforts to address climate change," said Hoffert.

"They deliberately created doubt when internal research confirmed how serious a threat it was. As a result, in my opinion, homes and livelihoods will likely be destroyed and lives lost." 

Exxon worked alongside Chevron, Shell, BP and smaller oil firms to shift attention away from the growing climate crisis. They funded the industry's trade body, API, as it drew up a multimillion dollar plan to ensure that "climate change becomes a non- issue" through disinformation. The plan said "victory will be achieved" when "recognition of uncertainties become part of the 'conventional wisdom.' "

The fossil fuel industry also used its considerable resources to pour billions of dollars into political lobbying to block unfavourable laws and to fund front organisations with neutral and scientific sounding names, such as the Global Climate Coalition (GCC). In 2001, the U.S. state department told the GCC that President George W. Bush rejected the Kyoto protocol to reduce greenhouse gas emissions "in part, based on input from you."

Exxon alone has funded more than 40 groups to deny climate science, including the George C. Marshall Institute, which one lawsuit claims orchestrated a "sham petition" denying man-made global climate change. It was later denounced by the National Academy of Science as "a deliberate attempt to mislead scientists."

Drilling down

To Sharon Eubanks the conspiracy to deny science sounded very familiar. From 2000, she led the U.S. justice department's legal team against nine tobacco firms in one of the largest civil cases filed under the Racketeer Influenced and Corrupt Organizations (Rico) Act, which was designed to combat organised crime.

In 2006, a federal judge found that the industry had spent decades committing a huge fraud on the American public by lying about the dangers of smoking and pushing cigarettes to young people.

Eubanks said that when she looked at the fossil fuel industry's strategy, she immediately recognised big tobacco's playbook.

"Big Oil was engaged in exactly the same type of behaviour that the tobacco companies engaged in and were found liable for fraud on a massive scale," said Eubanks. "The cover up, the denial of the problem, the funding of scientists to question the science. The same pattern. And some of the same lawyers represent both tobacco and big oil."

The danger for the fossil fuel industry is that the parallels do not end there.

The legal process is likely to oblige the oil conglomerates to turn over years of internal communications revealing what they knew about climate change, when and how they responded. Given what has already come out from Exxon, they are unlikely to help the industry's case.

Eubanks, who is now advising attorneys general and others suing the oil industry, said a turning point in her action against big tobacco came with the discovery of internal company memos in a state case in Minnesota. They included language that talked about recruiting young people as "replacement smokers" for those who died from cigarettes.

"I think the public was particularly stunned by some of the content of the documents and the talk about the need for bigger bags to take home all the money they were going to make from getting people to smoke," said Eubanks.

The exposure of the tobacco companies internal communications shifted the public mood and the politics, helping to open the door to legislation to curb smoking that the industry had been successfully resisting for decades.

Farber, the Berkeley law professor, said the discovery process carries a similar danger for the oil companies because it is likely to expose yet more evidence that they set out to deceive. He said that will undercut any attempt by the energy giants to claim in court that they were ignorant of the damage they were causing.

Farber said it will also be difficult for the oil industry to resist the weight of U.S. lawsuits, shareholder activism, and shifting public and political opinion. "It might push them towards settlement or supporting legislation that releases some from liability in return for some major concessions such as a large tax to finance responses to climate change."

The alternative, said Farber, is to take their chance on judges and juries who may be increasingly inclined to take the climate crisis seriously.

"They may think this is an emergency that requires a response. That the oil companies should be held responsible for the harm they've caused and that could be very expensive," he said. "If they lose, it's catastrophic ultimately."
