Progressive climate lawsuit supporters are publicly strategizing new legal tactics as the Supreme Court prepares to hear arguments that could halt state-led climate cases, drawing sharp warnings from critics about lawfare and judicial overreach.
With oral arguments in Suncor Energy v. County Commissioners of Boulder County set for October 5, a group of legal academics and activists gathered for a Center for Progressive Reform webinar to discuss how states and local governments might keep suing oil and gas companies if the nation’s highest court restricts such litigation. The panelists traded ideas on using state consumer-protection laws, tort claims, and even international human-rights strategies to hold energy producers accountable for alleged climate deception and damages.
The debate comes as Boulder County, the city of Boulder, and San Miguel County pursue a lawsuit they filed in 2018 against Suncor and ExxonMobil. The local governments argue the companies knowingly promoted fossil fuels while hiding or misrepresenting climate risks, seeking damages for alleged local effects of global emissions. Suncor and ExxonMobil counter that federal law, specifically the Clean Air Act, should preempt such state claims, since Congress set a nationwide framework for regulating air pollution decades ago, as reflected in the 1970 law and its later amendments.
The Supreme Court’s decision could reshape the legal landscape nationwide, much as the Court’s recent rulings have influenced political and regulatory fights on other issues, including access to political ad rates and congressional district maps as seen in major campaign and election cases. Advocates for climate litigation argue the stakes are high for communities forced to spend taxpayer dollars on adaptation, while critics see a coordinated lawfare campaign that threatens constitutional order and economic freedom.
During the Center for Progressive Reform event, panelists mapped out alternative strategies if the Supreme Court rules state courts cannot hear these claims. Robert Glicksman, a George Washington University Law School professor, told attendees that the Suncor case “provides an important opportunity for the courts to provide a mechanism by which local governments forced to spend public money on climate adaptation measures will have the opportunity to hold companies that extract and market fossil fuels accountable for their contributions to the problem.”
Rebecca Bratspies, a Tulane University Law School professor, suggested Boulder could try reframing its case as a consumer-protection action, but pointed out, “Boulder may now want to argue a consumer protection case, but that isn’t the lawsuit it filed or pursued.” She framed the Supreme Court’s core question as “whether a Colorado court can hear these allegations that the company’s violations of Colorado Consumer Protection Law cause harms in Colorado.”
Some panelists even looked beyond American courts. Lemir Teron, a Howard University professor, invoked Malcolm X and argued for considering climate change a human-rights issue, potentially opening the door to international forums like the United Nations or international criminal courts. “If we understand climate change as a human rights issue, then we open up ourselves to, in addition to state or federal claims, exploring some global options, whether that be the UN, international criminal courts,” Teron said.
Legal and policy voices on the right argue the wave of public-nuisance climate cases is a calculated attempt to force unpopular policies through the courts. Amy Cooke, director of the Energy and Environmental Policy Center at the Independence Institute, said Boulder’s suit is “effectively using the courts to impose a carbon tax it couldn’t get legislatively.” She warned that if local officials believe Colorado consumers were defrauded, they should “bring that case” by identifying “the deception, the consumers harmed and the damages caused”, but “that’s a different lawsuit.” For Cooke, “This is about climate change policy, not traditional consumer protection.”
O.H. Skinner, executive director of Alliance For Consumers, made the stakes clear: “In Suncor, the Court has a chance to end the activist lawfare campaign that seeks to use public nuisance climate cases to impose mandatory Progressive Lifestyle Choices on the American people and reshape the nation’s economy without a single vote in Congress.” He called on lawmakers to act: “Lawmakers in every state should rein in public nuisance law and ensure our nation’s economy is not controlled by court orders and ideologically-driven litigation.”
The Suncor case lands at a time when the Supreme Court is no stranger to major political fights, from congressional redistricting to hot-button regulatory disputes. The push to use state or international law to drive climate policy echoes past efforts to move controversial policies through litigation rather than through the ballot box or Congress, as recent battles over the Court’s size and legitimacy have shown in the debate over Supreme Court expansion.
This October, the Supreme Court will hear arguments on whether federal law preempts state-law climate claims seeking damages for interstate and international emissions. At issue is whether Colorado courts can proceed under state law despite the Clean Air Act’s federal framework, or whether Congress’s design leaves no room for local lawsuits over global climate impacts.
The case is being closely watched by those who see litigation as a backdoor attempt to force sweeping policy changes without legislative debate. It follows a pattern seen in Supreme Court interventions on campaign finance, congressional mapping, and other high-stakes questions such as emergency appeals over redistricting.
With climate litigation advocates open about pursuing new legal and international strategies, and critics warning of “woke lawfare” and an assault on democratic accountability, the Supreme Court’s decision in Suncor could set the tone for years to come. As seen in past showdowns over military policy and party campaign rules such as the Trump administration’s Supreme Court battles, the justices’ ruling could ripple far beyond Colorado’s borders.
For voters and taxpayers, it’s a reminder that the courtroom is no substitute for honest debate, and that the Constitution leaves lawmaking to elected representatives, not activist litigators or unaccountable judges.
