Michigan sues Big Oil ‘cartel’

Oil majors taken to court for climate deception & violating antitrust laws to limit energy options and drive up costs

The State of Michigan has filed an antitrust lawsuit in federal court against ExxonMobil, Chevron, Shell, BP and the American Petroleum Institute (API).

The lawsuit argues that the four oil majors and their largest trade organisation conspired together as a ‘cartel’ to block cleaner energy alternatives to fossil fuels in violation of state and federal antitrust laws.

Michigan is now the 11th state, and Attorney General Dana Nessel the 12th attorney general, to take Big Oil companies to court over their well-documented climate deception.

‘Michigan’s groundbreaking case reveals how the Big Oil cartel conspired to deny Americans cleaner and cheaper energy choices and make life less affordable by keeping consumers hooked on their dirty fossil fuel products. Eleven states and dozens of municipalities are now fighting to put Big Oil companies on trial for their climate lies and make them pay for the harm they’ve caused.

‘Big Oil is desperate to keep the evidence of their climate lies from juries in cases like Michigan’s, and that’s why the fossil fuel industry is now lobbying Congress for a get-out-of-jail-free card. Congress must protect the right of the people of Michigan and every state to hold Big Oil accountable for the harm their climate lies have caused.’

Making life less affordable

As more cases get closer to trial, the fossil fuel industry has been lobbying Congress for a legal shield that would give them immunity from climate lawsuits.

Earlier this month API announced that killing state climate lawsuits is a top 2026 priority for the oil lobby.

‘Michigan is facing an energy affordability crisis as our home energy costs skyrocket and consumers are left without affordable options for transportation. Whether you own a home, a small business, or run a large corporation, rising energy and transportation costs harm everyone.

‘These out-of-control costs are not the result of natural economic inflation, but due to the greed of these corporations who prioritised their own profit and marketplace dominance over competition and consumer savings.’

ATTORNEY GENERAL DANA NESSEL

Damage to Michigan’s economy

As detailed in the Attorney General’s lawsuit, as early as the 1950s, defendants learned that fossil fuel consumption would impose ‘significantly negative externalities’ on consumers and the natural environment, but hid that information from the public.

Defendants similarly concluded that customer demand would likely favour alternative energy sources as the negative harms of fossil fuel consumption became known and the negative externality costs associated with mitigating these harms publicly understood.

Despite this, over succeeding decades defendants engaged in a multifaceted scheme to maintain the dominance of fossil fuels by suppressing the production and availability of renewable energy substitutes, using trade organisations such as the American Petroleum Institute to coordinate industry-wide efforts to delay an energy transition.

As a result of this conspiracy, and its intended and accomplished goal of suppressed competition in energy markets, Michigan consumers suffer from ‘supracompetitive’ prices for fossil fuel energy products and reduced consumer choice in purchasing alternatives, driving an energy cost crisis in the State.

Michigan also suffers high costs in the form of climate change impacts and associated costs of adaptation and mitigation, rising insurance premiums, reduced home values and damage to Michigan’s economy.

Climate accountability lawsuits

11 US states – California, Connecticut, Delaware, Hawaii, Maine, Massachusetts, Michigan,  Minnesota, New Jersey, Rhode Island and Vermont – plus the District of Columbia and dozens of city, county and tribal governments in California, Colorado, Hawai`i, Illinois, Maryland, New Jersey, New York, Oregon, Pennsylvania, Washington and Puerto Rico, have active lawsuits to hold major oil and gas companies accountable for deceiving the public about their products’ role in climate change. These cases collectively represent more than one in four people living in the United States.

Cases from Boulder, Colorado, Honolulu, Hawaiʻi, the District of Columbia and the states of Massachusetts, Vermont, Minnesota and Connecticut are advancing towards discovery and trial after courts denied the companies’ motions to dismiss them.


Lobbying for immunity

The fossil fuel industry is lobbying Congress for immunity from climate accountability lawsuits.

Last year, 16 Republican attorneys general proposed creating a ‘liability shield’ for fossil fuel companies modelled on a 2005 law protecting gun manufacturers from lawsuits.

Lawmakers in Utah and Oklahoma have also introduced state-level immunity bills for the fossil fuel industry.
