Supreme Court to weigh energy companies' bid to end Boulder climate-change lawsuit

Key Points:

• The Supreme Court is set to hear a major climate change case involving Boulder, Colorado, which seeks to hold Exxon Mobil and Suncor Energy accountable for damages linked to global warming caused by fossil fuel emissions.
• The central legal question is whether Boulder's state-law claims can proceed or are preempted by federal law, with Exxon and Suncor arguing that the Clean Air Act and the Constitution bar such lawsuits due to the interstate and international nature of greenhouse gas emissions.
• The case raises broader issues about federalism, state versus federal authority in regulating climate change, and potential conflicts with U.S. foreign policy, with 26 states supporting the fossil fuel companies and Boulder defending its right to seek local remedies for climate harms.
• Justice Samuel Alito has recused himself from the case, leaving eight justices to decide, which could result in a 4-4 split that would uphold the Colorado Supreme Court's ruling allowing the case to proceed.
• A Supreme Court decision is anticipated by summer 2027, with experts noting that Congress could intervene legislatively to limit such lawsuits if deemed necessary.
