Feds sue Minnesota to block landmark climate lawsuit against Exxon Mobil

The federal government has taken legal action against Minnesota in an attempt to halt the state’s long-running lawsuit against Exxon Mobil and other energy firms. The dispute centres on whether Minnesota can pursue claims that these companies misled the public about climate change for decades. Officials in Washington argue that federal law—not state courts—should govern greenhouse gas regulation.

Minnesota’s lawsuit, filed years ago, accuses Exxon Mobil and other energy companies of violating consumer protection laws. The state claims the firms knew about the impacts of climate change as early as the 1970s but deliberately downplayed the risks and spread misinformation. The case has faced repeated delays due to disputes over jurisdiction and free speech concerns, with all previous motions to dismiss being rejected.

The federal government’s new lawsuit seeks an injunction to block Minnesota’s legal action entirely. It argues that the state’s claims are 'preempted and unlawful' and that regulating emissions falls under federal authority. The Justice Department also contends that Minnesota’s lawsuit threatens energy affordability and grid reliability. Minnesota Attorney General Keith Ellison has dismissed the federal case as 'frivolous and meritless'. He has pledged to file for its dismissal, insisting the state has the right to hold companies accountable for alleged deception. Meanwhile, the Trump administration is also challenging similar 'climate superfund' laws in Vermont and New York, aiming to prevent their implementation. The broader legal battle over climate accountability is intensifying. The US Supreme Court is set to review another major case—Boulder, Colorado’s climate lawsuit—during its upcoming term. The Justice Department has filed comparable suits against other states in recent years, though with inconsistent outcomes.

The federal government’s intervention adds another layer to Minnesota’s prolonged legal fight against energy companies. If successful, the injunction could stop the state’s lawsuit in its tracks. The outcome may also influence other climate-related cases currently moving through the courts.
