A Paris court has handed down a landmark ruling in one of Europe's most closely watched climate cases, ordering French energy giant TotalEnergies to formally account for the greenhouse gas emissions generated by its customers' use of its oil and gas products. While the decision stopped short of forcing production cuts demanded by environmental groups, it marks the first time France's corporate duty of vigilance law has been applied directly to climate change.
What the Court Actually Ordered
A Paris court ruled on Thursday that French oil major TotalEnergies must disclose the climate risks linked to emissions from its oil and gas products and set out plans to address them. The court gave the French oil giant six months to report the environmental risks caused by the consumption of its gas and oil products, and scheduled a new hearing for January to consider TotalEnergies' new assessment under the relevant legal framework.
The court was explicit about which category of emissions falls within the company's legal duty. "Scope 3 greenhouse gas emissions are among the emissions resulting from the group's activities within the meaning of the law, due in particular to the inherent link between oil and gas production and the combustion of the products by users," the court said. "Climate-related risks and impacts to which the company may contribute through its activities fall within the scope of the law on the duty of vigilance for parent companies and ordering companies," the court added.
Why This Case Matters Legally
The ruling represents a genuine legal first for France. It's the first time that the so-called corporate duty of vigilance law is being applied to climate change. The law is not intended to make companies "responsible for the risks linked to climate change, which result from all human activity on the planet since the Industrial Revolution," the court said in its statement, but rather requires them to act accordingly within their sphere of influence.
City officials hailed the decision as a watershed moment in French environmental law. The city of Paris hailed the ruling as "a landmark decision in the history of French climate law." Deputy Mayor Alice Timsit said, "For the first time, a judge recognises that climate risks do indeed fall under the duty of vigilance owed by large corporations, and no fossil-fuel multinational can evade this responsibility". "The city joined this lawsuit because we are experiencing firsthand the impact of climate change on a densely populated, urban metropolis," Timsit said, as France and other European countries baked under a record-breaking heatwave.
Where the Court Drew the Line
Despite the symbolic significance of the ruling, the plaintiffs' more aggressive demands were rejected outright. The NGOs wanted the court to order a halt in new fossil fuel projects by TotalEnergies along with production cuts of 37 percent for oil and 25 percent for gas by 2030. But the court declined to impose such measures, saying the law does not allow the judge to "take the place of the company" to demand the implementation of specific actions.
That refusal was reinforced by an unusual intervention from the state itself. In a rare move, the Paris public prosecutor also intervened in the civil proceedings and echoed TotalEnergies' stance, warning that imposing an overly broad protection obligation on companies would not be workable.
The Scale of the Emissions at Stake
The case centered on TotalEnergies' refusal to formally account for emissions generated after its products leave the company's control. The plaintiffs specifically accused TotalEnergies of refusing to account for indirect emissions from end users, which they say amounted to 342 million tonnes of CO2 equivalent in 2024. For context, that figure dwarfs the annual emissions of many entire countries, underscoring why campaigners viewed formal accounting of these "Scope 3" emissions as a critical legal precedent.
TotalEnergies' Response
The company framed the outcome as a partial vindication of its position. TotalEnergies expressed "satisfaction" that the court didn't ban it from pursuing new oil and gas projects or force it to reduce oil and gas production. In a statement, the company said it will update its climate policies following the ruling, and noted it has expanded development of other energy sources and reduced emissions of its operations by 28% since 2015.
Throughout the proceedings, TotalEnergies maintained that singling out one company wouldn't meaningfully address global emissions. TotalEnergies said it was the victim of "demonisation" by the plaintiffs, with its lawyers arguing that climate change would continue even if the company, which accounts for less than two percent of global production, shut its operations. The company called the measures requested by the plaintiffs unreasonable and ineffective, arguing that production cuts or cancelled projects would simply shift output to competitors.
A Years-Long Legal Battle
This ruling caps off a case that has run for more than half a decade and survived multiple procedural challenges. The case, opened in 2020, had produced interim wins for campaigners. In 2024, the Paris appeals court allowed the lawsuit to proceed but dismissed claims from several local authorities, including New York City, which had sought to join the case. Only the city of Paris was recognised as having standing. The four NGOs behind the case — alongside the city of Paris — argued that the law's reference to prevention of environmental risks encompasses both local pollution and climate change, a position the court has now formally endorsed.
Part of a Growing Global Pattern
This case fits into a much broader, worldwide wave of corporate climate litigation with decidedly mixed results so far. In late 2024, a Dutch appeals court overturned a landmark ruling that had ordered Shell to deepen emissions cuts, with the country's Supreme Court due to issue a final ruling on the case. Last year, the United Nations' top court, the International Court of Justice, said that countries could be in violation of international law if they fail to take measures to protect the planet from climate change, while in 2024, the European Court of Human Rights ruled that countries must better protect their people from the consequences of climate change.

What Happens Next
With a follow-up hearing scheduled for January to review TotalEnergies' new emissions assessment, the real test of this ruling's impact will come down to enforcement — whether the company's revised climate disclosures meaningfully change its practices, or simply satisfy a paperwork requirement without altering its underlying business strategy. Either way, campaigners are likely to point to this ruling as a template for future climate litigation against major fossil fuel companies across Europe.
