The U.S. Department of Justice (DOJ) has initiated legal action against Hawaii, Michigan, New York, and Vermont, challenging the constitutionality and impact of state-level climate change initiatives. The lawsuits argue that these initiatives overstep state authority and interfere with federal jurisdiction over interstate commerce and international affairs.
In particular, the DOJ has targeted the climate superfund laws of New York and Vermont. These laws, enacted in 2024, seek to hold fuel companies financially accountable for climate-related damages, mirroring the federal Superfund law of 1980, which addresses hazardous waste sites through strict liability. This approach, however, faces potential legal challenges. The Second Circuit Court of Appeals previously ruled against using state tort law to impose penalties on multinational companies for greenhouse gas emissions, as global warming poses unique international challenges.
The DOJ claims these state superfund laws are preempted by the Clean Air Act and argues that New York and Vermont’s legislative actions have exceeded the bounds of state power. In response, a coalition of 24 states has filed a lawsuit opposing New York’s superfund, while the Supreme Court recently declined to review a similar case involving 19 states.
Separately, Hawaii and Michigan are under scrutiny for potential lawsuits targeting fossil fuel companies for climate-related damages. Hawaii has filed a lawsuit against several fuel companies, and Michigan has aligned with three private law firms for possible litigation. Columbia Law School professor Michael Gerrard expressed skepticism about the DOJ’s move, labelling it “an aggressive move in support of the fossil fuel industry.”
The DOJ warns that these state-level initiatives could undermine energy production efficiency and increase costs for American consumers, while leaving the nation vulnerable to foreign threats. Acting Assistant Attorney General Adam Gustafson emphasized the potential national security risks, stating: “When states seek to regulate energy beyond their constitutional or statutory authority, they harm the country’s ability to produce energy and they aid our adversaries.” Michigan Attorney General Dana Nessel criticized the DOJ’s approach as an “unprecedented preemptive intervention.”
These legal actions occur in the context of recent executive actions on climate and energy policies, including President Trump’s Executive Order 14260, aimed at protecting American energy from overreach by states, and Executive Order 14156, declaring a national energy emergency.
