Michigan AG Nessel sues big oil over ‘cartel’-like plot to kill clean energy

Michigan Attorney General Dana Nessel is suing some of the world’s largest oil companies, accusing them of colluding for decades to keep renewable energy and electric vehicles on the margins.

The landmark lawsuit, expected to be filed this morning in the US District Court for the Western District of Michigan, seeks unspecifiedfinancial compensation and forfeiture of profits from oil giants BP, Chevron, Exxon Mobil, Shell and their subsidiaries, as well as the industry lobbying group American Petroleum Institute.

With the suit, Michigan joins dozens of cities and states that have sued oil corporations, claiming they used illegal tactics to maintain market dominance and conceal the risks of their products.

Petroleum industry representatives have begun lobbying Congress for legal immunity, calling such lawsuits a waste of taxpayer resources.

“This cadre of state lawsuits and laws is not only an attack on the companies that provide Americans with affordable and reliable energy, but also an unconstitutional affront to the federal government’s role in setting national energy and climate policy,” said Ryan Meyers, senior vice president and general counsel for the American Petroleum Institute.

Today’s suit comes more than a year-and-a-half after Nessel first announced plans to sue the fossil fuel industry over climate change.

Rather than a suit about environmental harm, Nessel said in an interview with Bridge Michigan, “at the heart, this is an energy affordability case.”

Michiganders pay among the nation’s highest residential energy rates — costs Nessel said “could have been prevented had the fossil fuel cartel not worked together to postpone innovation and to eliminate cost-effective alternatives.”

While many other state and local lawsuits have accused oil companies of violating environmental and public trust laws, Michigan’s case hinges on antitrust laws designed to protect consumers from monopolies.

In the 126-page complaint, state lawyers argue the fossil fuel companies acted like a cartel, conspiring to thwart competition from EVs and renewable energy. That includes using “capture-and-kill tactics” such as buying renewable energy patents and then restricting their use, suing rival companies to keep them from deploying EVs and renewables, misleading the public about the risks of fossil fuels and hiring hackers to “surveil, intimidate and disrupt” investigations by journalists and activists.

Taken together, the lawsuit alleges, those actions amount to “an illicit conspiracy” to restrain free trade. In a world without such collusion, the lawsuit states, Michiganders would have more and cheaper transportation and energy options while avoiding the “staggering external costs” of climate change.

Oil company executives knew as far back as the 1960s that fossil fuels cause climate change, but spent decades publicly denying the science.

Greenhouse gas emissions caused by burning fossil fuels have destabilized Earth’s climate, prompting a global panel of experts to warn that humanity must stop emitting by 2050 or face dangerous “tipping points” such as mass extinction and runaway sea level rise, heatwaves, droughts and fires.

Last year was the third-hottest year on record, just barely cooler than 2023 and 2024.

Even before it was filed, Nessel’s lawsuit drew a rebuke from the Trump administration.

Trump, who campaigned on a promise to “unleash” American oil and gas, has spent the first year of his second term bolstering fossil fuels.

In May, his Department of Justice preemptively sued Michigan, with US Attorney General Pam Bondi arguing that state climate lawsuits “threaten American energy independence and our country’s economic and national security.”

That case is pending in US District Court.

In addition to rolling back regulations on greenhouse gases and toxic coal plant pollution, Trump has canceled tens of billions of dollars’ worth of federal climate grants and clean energy subsidies while pushing instead to expand subsidies for fossil fuels.

Some $540 million in climate-related grants to Michigan have been canceled or held up since Inauguration Day. Nessel has sued the administration in hopes of reversing some of those cuts.

Nessel’s antitrust case will likely not conclude before she leaves office at the end of 2026. She expressed hope that her successor will continue to pursue the case, regardless of their party affiliation.

“Michigan is facing this affordability crisis when it comes to our energy,” she said. “This is not a partisan issue.”
