Even as the Trump administration moves to block state and local climate liability efforts, states and municipalities continue to advance lawsuits seeking to hold fossil fuel companies liable for harms associated with climate change. Most recently, the State of Hawaii initiated a climate deception lawsuit, and the City of Charleston, South Carolina, submitted a briefing in a pending case—each alleging that the fossil fuel industry engaged in a decades-long campaign to mislead the public about the risks of fossil fuel consumption and climate change. Both developments come as the Trump administration escalates its opposition to such suits, issuing on April 8 an executive order (EO), Protecting American Energy From State Overreach, targeting and filing lawsuits making constitutional challenges to state-led climate litigation and legislative actions—including a preemptive action against Hawaii just days before the state’s filing.
