U.S. Supreme Court rejects Big Oil attacks on Hawaii climate lawsuit

Climate campaigners and scientists on Monday welcomed the U.S. Supreme Court's decision to reject attempts by fossil fuel giants to quash the Hawaii capital's lawsuit aiming to hold the major polluters accountable for the devastating impacts of their products.

"This is a significant day for the people of Honolulu and the rule of law," Ben Sullivan, executive director and chief resilience officer at the City and County of Honolulu's Office of Climate Change, Sustainability, and Resiliency, said in a statement.

"This landmark decision upholds our right to enforce Hawaii laws in Hawaii courts, ensuring the protection of Hawaii taxpayers and communities from the immense costs and consequences of the climate crisis caused by the defendants misconduct," he added.

Honolulu first sued companies including BP, Chevron, ConocoPhillips, ExxonMobil, Shell, and Sunoco in March 2020. The companies have fought to shut down the case—like dozens of other climate liability lawsuits that states and municipalities have filed against Big Oil at the state level.

Shell and Sunoco led a pair of appeals to the Supreme Court, arguing that Honolulu's suit was "a blueprint for chaos" because it could inform other legal actions against fossil fuel companies and such cases "could threaten the energy industry." Similar to three previous decisions, the justices declined to intervene.

Center for Climate Integrity president Richard Wiles connected Monday's victory to the other cases, saying in a statement that "Big Oil companies keep fighting a losing battle to avoid standing trial for their climate lies."

"With this latest denial, the fossil fuel industry's worst nightmare—having to face the overwhelming evidence of their decades of calculated climate deception—is closer than ever to becoming a reality," Wiles continued. "Communities everywhere are paying dearly for the massive damages caused by Big Oil's decadeslong climate deception. The people of Honolulu and communities across the country deserve their day in court to hold these companies accountable."

Delta Merner, lead scientist for the Union of Concerned Scientists' Science Hub for Climate Litigation, similarly celebrated the decision, which she called "a resounding affirmation of Honolulu's right to seek justice under state law for the mounting climate impacts caused by fossil fuel companies' deceptive practices."

"For more than 50 years, fossil fuel companies have conducted sophisticated disinformation campaigns to obscure their own research showing that burning fossil fuels would drive climate change," Merner highlighted. "This case lays bare how these actions have contributed to rising seas, intensified storms, and coastal erosion that are devastating Honolulu's people, infrastructure, and natural resources."

"Scientific evidence is unequivocal: The human-caused emissions from fossil fuels are the primary driver of climate change," she stressed. "Honolulu's case stands as an example of how communities are using both science and the law to challenge corporate misconduct and demand accountability for climate damages."

Merner added that "the people of Honolulu are demonstrating remarkable leadership in standing up to powerful fossil fuel companies whose disinformation campaigns have directly contributed to the climate harms they now face. Their efforts serve as a powerful example for communities around the world. This decision is one step in a larger effort to seek accountability and justice."

The Supreme Court's latest blow to the oil and gas industry came just a week before the second inauguration of President-elect Donald Trump, who courted Big Oil executives on the campaign trail and pledged to "drill, baby, drill" if he won the November election.

The high court—which has a right-wing supermajority that includes three Trump appointees—had asked the Biden administration to weigh in. Last month, U.S. Solicitor General Elizabeth Prelogar urged the justices not to intervene. Merner said at the time that her briefs "represent an important step in the pursuit of climate accountability."
