Louisiana Gov. Jeff Landry signed the Louisiana Energy Protection Act into law, blocking civil lawsuits in state courts that seek damages from energy companies over greenhouse gas emissions and climate change. The measure, House Bill 804, cleared the state legislature with overwhelming bipartisan margins, 92-5 in the House and 31-3 in the Senate, before landing on Landry's desk after the 2026 session ended June 1.
Landry framed the new law as a direct check on legal theories that treat climate change as grounds for holding individual companies liable. At a news conference following the signing, the governor told reporters:
"In signing that bill, basically it says that people can't theorize the fact that climate change is manmade and then take that as a theory and hold those companies that are producing energy liable for that."
He described the legislation as "closing the door to frivolous litigation." The bill's sponsor, Rep. Brett Geymann, R-Lake Charles, used blunter language, calling the lawsuits the bill targets "climate lawfare."
The law bars civil lawsuits filed in Louisiana state courts that seek personal injury, property, or economic damages tied to greenhouse gas emissions and global climate change. That language covers a wide swath of the legal landscape, shielding not just oil and gas producers but chemical manufacturers, agricultural groups, trucking companies, timber associations, and cattle operations that backed the final version of the bill.
The law does not grant blanket immunity. Companies can still face suit in Louisiana courts if they violate government-mandated emission caps, workplace safety standards, or the explicit terms of their environmental permits. The distinction matters: the legislation targets speculative, climate-theory-based claims while preserving enforcement of existing environmental law.
Geymann, who chairs the House Natural Resources and Environment Committee, told the Senate Natural Resources Committee that the purpose was straightforward:
"The purpose is to prevent lawsuits against fossil fuel companies, against people, against businesses, against government agencies, against nonprofits, for a claim for damages related to climate change."
He said he looked at bills in Oklahoma and Utah for guidance when writing the legislation, noting that other states are adopting similar protections. The trend suggests a growing red-state consensus that climate litigation amounts to policy-by-lawsuit, an end-run around legislatures by activist lawyers and environmental groups.
Oil producers and natural gas processors backed House Bill 804 heavily, but the coalition extended well beyond the energy sector. Chemical manufacturers, agricultural groups, trucking companies, timber associations, and cattle associations all lined up in support, reflecting the breadth of industries that could face climate-related liability theories.
Tommy Faucheux, president of the Louisiana Mid-Continent Oil and Gas Association, called the law's passage one of the signature accomplishments of the past legislative session:
"This legislation was an important step to prevent the national trend of climate change lawsuits from coming to Louisiana while also chipping away at our state's own destructive litigation climate."
Environmental advocacy groups pushed back hard during committee testimony, arguing the legislation goes too far in shielding corporate polluters. The Sierra Club's Delta Chapter in New Orleans was among the opponents, contending the law strips local communities and coastal parishes of legal rights to hold large industries financially accountable for the economic impacts of rising sea levels and intensifying gulf storms.
That argument deserves scrutiny. Louisiana's coast faces real erosion and storm-damage costs. But the question the legislature answered, by margins that approached unanimity, is whether individual lawsuits premised on global climate theory are the right mechanism for addressing those costs. Ninety-two House members and thirty-one senators said no.
The Louisiana Energy Protection Act is not an isolated move. Landry has positioned Louisiana as one of the most aggressive states in the country on energy policy. National Review reported that Landry also signed Act 462, formerly HB 692, directing the state to prioritize domestic fossil fuel and nuclear energy production over wind and solar. That law requires the Louisiana Department of Energy and Natural Resources to focus on domestic fuel production rather than energy sources dependent on foreign materials.
The governor has described these moves as pursuing "energy independence and dominance." AP News reported that Louisiana also became the latest Republican-led state to classify natural gas as "green energy," following similar laws in Indiana, Ohio, and Tennessee. That law orders state agencies and utility regulators to prioritize natural gas and nuclear power, citing electricity affordability and reliability.
Environmental groups have objected to the natural gas reclassification as well, warning it could allow funds intended for clean energy initiatives to support natural gas instead. Greenpeace USA research director Tim Donaghy called the effort "pure Orwellian greenwashing." But the legislative votes tell a different story about where Louisiana's elected representatives, and their constituents, stand on the question.
The pattern in Baton Rouge mirrors a wider dynamic playing out in state capitals and in Washington, where major legislation continues to advance along partisan and ideological lines, with Republican governors and legislatures moving to lock in policy priorities through statute rather than waiting for federal action.
Geymann's use of the phrase "climate lawfare" captures a real and growing phenomenon. Across the country, municipalities, state attorneys general, and environmental organizations have filed suits against energy companies seeking damages for everything from coastal erosion to wildfire costs to public health effects, all tied to greenhouse gas emissions and climate change.
These suits often rely on creative legal theories that attempt to hold individual companies responsible for the cumulative effects of global emissions. The plaintiffs typically argue that fossil fuel companies knew about climate risks and misled the public. Defendants counter that energy production is a lawful, heavily regulated activity and that climate policy should be set by legislatures, not by juries in sympathetic jurisdictions.
Louisiana's law takes the legislative route explicitly. By barring these claims in state court, it removes the possibility that a single parish jury could impose sweeping liability on an entire industry. The carve-outs, for violations of emission caps, safety standards, and permit terms, preserve traditional environmental enforcement without opening the door to speculative climate damages.
States like Oklahoma and Utah have moved in the same direction. The question now is whether more states follow, or whether federal courts and judges sympathetic to the environmental movement find ways to keep the litigation pipeline open despite state-level barriers.
The lopsided margins in the Louisiana legislature, 92-5 and 31-3, are worth pausing on. This was not a party-line squeaker. Democrats joined Republicans in overwhelming numbers. In a state where energy production is woven into the economy from the Gulf Coast to the northern parishes, the political math was never close.
That breadth of support also reflects a practical calculation. Climate lawsuits don't just threaten oil companies. They threaten trucking firms, cattle ranchers, timber operations, and chemical plants. When the litigation theory is broad enough to reach any entity that produces or uses fossil fuels, the coalition opposing it gets broad in a hurry.
Opponents will argue that the law protects polluters at the expense of vulnerable coastal communities. But the legislation preserves every existing avenue for suing companies that break environmental rules. What it closes is the speculative path, the one where a plaintiff's lawyer argues that a single company's lawful emissions caused a hurricane to intensify or a coastline to recede.
That is not accountability. That is a legal lottery, and Louisiana's legislature decided the state's economy shouldn't be the jackpot. The dynamic is not unlike the politically charged legislation emerging from other statehouses, where governors are signing bills that draw sharp ideological lines and force national debates into state-level action.
Environmental groups will almost certainly challenge the Louisiana Energy Protection Act in court. Whether they can find a constitutional hook remains to be seen. State legislatures have broad authority to define causes of action in their own courts, and the law's carve-outs for permit violations and safety standards undercut any argument that it eliminates all environmental remedies.
The broader fight over climate litigation is far from over. Suits are pending in multiple states and federal courts. But Louisiana has drawn a clear line: lawful energy production is not a tort. The state that produces more oil and gas than nearly any other has decided that its courts will not be weaponized against the industry that keeps its economy running.
In an era when legislative battles increasingly define the political landscape, Landry and the Louisiana legislature chose to settle this fight with votes rather than verdicts. Other energy-producing states are watching closely.
When ninety-two legislators and a governor agree that courtrooms are the wrong place to set climate policy, maybe the activists filing these suits should take the hint.
