ALF Urges Supreme Court To Decide Whether Federal Law Precludes Climate Change Damages Suits

State and local governments have filed dozens of damages suits in state courts around the United States collectively seeking billions of dollars  from major oil and gas producers for the alleged local effects of global warming and climate change.  The potentially disastrous national and international ramifications of allowing these proliferating suits to proceed are enormously important—not only for the defendant fossil fuel companies, but also for the nation’s economy, critical infrastructure, and national defense.  The everyday lives of virtually every American will be adversely affected in numerous ways if these suits succeed in crippling the fossil fuel industry.

Case Background

The 115-page state-court complaint filed by the City and County of Honolulu, Hawaii against major fossil fuel producers is similar to complaints that have been filed by state and local governments around the United States.  Although the complaint includes causes of action for nuisance, trespass, and failure to warn, it alleges that the defendant fossil fuel companies should be held liable for “causing global climate change and dire effects on the planet.”

The defendant fossil fuel companies contend that Honolulu’s state-law suit is precluded by federal law due to the inherently interstate nature of atmospheric greenhouse gas pollution and/or by the preemptive effect of the Clean Air Act.   But according to the Hawaii Supreme Court,  “this is a traditional tort case” that should be allowed to proceed.  The companies are seeking U.S. Supreme Court review.

On behalf of the Atlantic Legal Foundation, I have filed an amicus brief urging the Supreme Court to grant review in Sunoco LP v. Honolulu (23-947) & Shell PLC v. Honolulu (23-952) and hold that federal law precludes climate change damages suits.

ALF’s Amicus Brief

ALF’s amicus brief argues that the extraordinary subject of Honolulu’s suit—alleged responsibility for causing or contributing to global warming and worldwide climate change—is beyond the bounds of traditional state tort law. By viewing Honolulu’s suit as an ordinary product liability case, the Hawaii Supreme Court elevated artful pleading over the true nature of allegations that fossil fuel producers should be held liable for their alleged alteration of the global climate.

The amicus brief explains that there are multiple types and sources of greenhouse gas emissions, and that climate change is both borderless and indivisible. Fossil fuel companies’ alleged liability for causing global climate change cannot be fragmented into myriad state and local pieces.  Allowing state courts around the nation to adjudicate climate change damages suits brought by state and local governments against fossil fuel companies likely would result in conflicting or inconsistent judgments, including imposition of greenhouse gas abatement measures, that would seriously undermine the Clean Air Act’s comprehensive federal-state regulatory scheme.

The Supreme Court should review the Hawaii Supreme Court’s ruling and hold that federal law precludes climate change damages suits.
