A Court Weighs Climate Lawsuit's Impact on National Security
A Charleston lawsuit against major oil companies raises questions about climate change and national security in light of a Trump executive order.
May 30, 2025, 7:48 p.m. ET - In a notable courtroom clash this week in Charleston, South Carolina, legal teams sparred over significant implications surrounding environmental lawsuits and their potential fallout. Central to the debate is the assertion from former President Trump that lawsuits against oil companies may pose a national security threat.
This case, filed by the City of Charleston, accuses ExxonMobil, Chevron, and a number of their industry counterparts of engaging in a decades-long campaign to misinform the public about the risks associated with climate change. An executive order from Trump, recently issued, describes such lawsuits as risking destabilizing financial damages.
The hearings in Charleston mark the first instance where attorneys have had to directly engage with Trump’s claims in a formal legal setting. His executive order appears to be a strategic part of a larger government push against legal actions that target oil companies for their roles in climate change.
Furthermore, the Justice Department has stepped in, filing lawsuits against states like Hawaii and Michigan to prevent them from pursuing their own climate litigation. Nevertheless, Hawaii has opted to proceed with its case, and Michigan’s attorney general has indicated intentions to move forward as well.
During recent hearings, presiding Judge Roger M. Young Sr. requested both parties present their views on the executive order while addressing motions to dismiss the case, which has been pending since 2020.
The defendants' attorney, Theodore J. Boutrous Jr. of Gibson Dunn, argued that the executive order served to reinforce their stance that emissions regulation falls under federal law, thus rendering state-level climate lawsuits inappropriate. As the legal battle unfolds, the intersection of climate litigation and national security continues to garner widespread attention.
