The Chevron lawsuit in Louisiana ended with a jury awarding $744.6 million for wetland restoration.
Chevron has been ordered to pay $744.6 million in damages after a Louisiana jury found the oil giant responsible for decades of environmental damage to the state’s fragile coastal wetlands. The case, brought by Plaquemines Parish in southeast Louisiana, is the first of many pending lawsuits targeting oil companies for contributing to land loss in the state. Legal experts and environmental groups say the verdict could influence dozens of similar lawsuits pending.
This historic decision centers around the Chevron lawsuit in Louisiana, which accused the company—via its predecessor Texaco—of breaking coastal protection laws and failing to clean up after drilling operations. The jury found Chevron liable for land loss, soil contamination, and the abandonment of equipment in the marshes.
The jury awarded $575 million for land restoration, $161 million for contamination damages, and $8.6 million for the cost of abandoned equipment. When interest is factored in, the total owed rises to more than $1.1 billion. Plaquemines Parish had originally sought $2.6 billion, but attorneys representing the parish said the jury’s decision still marks a strong win.
Chevron has said it plans to appeal, claiming the activities in question predated the environmental law under which the parish sued. Still, the verdict sends a powerful message that oil companies may be held accountable for decades-old environmental practices.
The Chevron lawsuit in Louisiana argued that the company violated a 1978 law requiring oil firms to clean and restore wetlands after operations ended. The law applies even to older sites still in use.
Evidence presented at trial showed that Texaco, which merged with Chevron in 2001, dumped billions of gallons of untreated wastewater into Louisiana’s marshes and dredged thousands of miles of canals through fragile wetland systems. These actions, according to experts, destroyed natural protections and worsened the impact of sea level rise, hurricanes, and flooding.
Over the past 100 years, Louisiana has lost more than 2,000 square miles of coastal land—an area larger than the state of Delaware. Without action, state officials warn, another 3,000 square miles could disappear in the coming decades. These wetlands are vital not just to the ecosystem but also to major U.S. ports and oil infrastructure.
Chevron’s lead attorney, Mike Phillips, argued that the company followed the law and blamed the land loss on other causes, including levees along the Mississippi River that prevent sediment from naturally rebuilding the delta. Phillips said that holding the company liable for historic practices sets a dangerous legal precedent.
Chevron also criticized the proposed $1.1 billion restoration plan, calling it unrealistic and more about inflating damages than fixing the coastline.
Despite the defense, the jury decided Chevron’s actions played a major role in Louisiana’s coastal erosion and that the company should pay to fix the damage.
The Chevron lawsuit in Louisiana is just the beginning. Plaquemines Parish alone has filed 20 more cases against various oil and gas companies. In total, dozens of similar lawsuits are making their way through Louisiana’s court system.
Many legal observers believe the Chevron verdict may prompt other companies to settle rather than risk losing in court. The pressure is mounting, especially as Louisiana faces a funding gap for its long-term coastal restoration projects. Much of the current funding came from BP’s settlement after the 2010 Deepwater Horizon oil spill, but those funds are running out.
Governor Jeff Landry, a pro-industry Republican, has supported the lawsuits. He brought the state on board during his time as attorney general, despite opposition from oil industry lobbyists.
Oil companies have repeatedly attempted to have the lawsuits transferred to federal court, where they believe judges might be more sympathetic. So far, those efforts have failed. They also lobbied the state legislature to pass a law to stop the lawsuits altogether, but that too was unsuccessful.
The outcome of the Chevron lawsuit in Louisiana could change how oil companies operate in coastal regions. It also puts pressure on them to clean up past pollution and restore the ecosystems they damaged. That could mean billions of dollars in payouts if more juries find them liable.
Supporters of the lawsuits argue that the money is essential to saving Louisiana’s coast, which protects communities, businesses, and critical energy infrastructure. Opponents say that it could harm the state’s economy and deter future investment in oil and gas projects.
Tommy Faucheux, president of the Louisiana Mid-Continent Oil & Gas Association, warned that the verdict threatens Louisiana’s status as a national energy leader. He also said the ruling could lead to retroactive lawsuits that punish companies for following older laws.
But attorneys for Plaquemines Parish believe the payout could spark positive change.
They say the verdict sends a clear message that companies can no longer ignore environmental responsibility. According to lead attorney John Carmouche, restoring Louisiana’s wetlands isn’t just about cleaning up the past—it’s about protecting the state’s future.
