Courts have a major role in ensuring responsibility is taken seriously
In The Hague, the Dutch Supreme Court received the final arguments in a years-long contest between Shell and environmental group Milieudefensie — a dispute that is, at its heart, a question as old as governance itself: when democratic institutions move too slowly to meet a crisis, can courts step in to compel action? The case has already traveled through two lower courts, producing a landmark 2021 ruling that was later overturned, and now rests with the country's highest judges, whose decision in early 2026 may redraw the boundaries of corporate accountability across the world. What hangs in the balance is not merely one company's emissions targets, but the deeper question of whether the judiciary is a legitimate instrument of civilizational survival.
- A 2021 ruling that stunned the fossil fuel industry — ordering Shell to cut emissions 45% by 2030 — was overturned in 2024, leaving climate advocates without the hard legal mandate they had won.
- Milieudefensie's lawyer argued in the Supreme Court that judges are the last reliable check on corporations when governments fail to enforce climate commitments with any real consequence.
- Shell's defense framed judicial intervention as dangerous overreach, warning that courts imposing emissions targets on individual companies would produce legal chaos without the coordination only governments can provide.
- The appeals court's vague instruction for Shell to make an 'appropriate contribution' to Paris goals satisfied neither side, leaving the company's actual obligations in a legal gray zone.
- A separate Milieudefensie lawsuit seeking to block Shell from investing in new oil and gas fields signals that this battle extends beyond regulating current operations into constraining the company's future entirely.
- The Supreme Court's expected 2026 ruling is being watched across Europe and beyond — a decision for either side could either open or close the courthouse door to corporate climate litigation worldwide.
On a Friday morning in May, Shell and Dutch environmental group Milieudefensie stood before the Supreme Court in The Hague to make their final arguments in a case that has already reshaped how the world thinks about climate litigation. The question before the court was stark: can a judge order an oil company to cut its carbon emissions?
The dispute has a long history. In 2021, a lower court issued what many called a landmark ruling, requiring Shell to reduce its emissions by 45 percent by 2030. It was a stunning moment — judges imposing hard numbers on a fossil fuel giant. But in 2024, an appeals court reversed the decision, finding that Shell was already meeting its legal obligations and replacing the specific target with vague language asking only for an 'appropriate contribution' to Paris climate goals.
With the case now at the country's highest court, both sides made their sharpest arguments. Milieudefensie's lawyer Roger Cox told the judges that courts have a responsibility to hold corporations accountable for climate harm — that without judicial intervention, human rights and environmental protections would remain unenforced. Shell's lawyer Freerk Vermeulen countered that emissions regulation belongs to governments and international bodies, not judges, and that court orders targeting individual companies would create legal disorder without the coordination that only democratic institutions can provide.
The disagreement cuts to something fundamental: the proper role of courts in a climate emergency. Global emissions continue to rise nearly a decade after the Paris Agreement, and Milieudefensie's position is that symbolic commitments without judicial enforcement are meaningless. Shell's position is that judicial overreach threatens the rule of law itself.
Milieudefensie is also pursuing Shell in a separate lawsuit aimed at blocking the company from investing in new oil and gas fields — a second front in the same broader war. The Supreme Court is expected to rule in the first half of 2026, and its decision will be watched closely across Europe and beyond. A ruling for Milieudefensie could open new pathways for climate litigation worldwide; a ruling for Shell could signal that courts should leave emissions policy to governments and markets. Either way, the decision will help define who holds the power to determine how quickly the world moves away from fossil fuels.
On a Friday morning in May, Shell and a Dutch environmental group called Milieudefensie stood on opposite sides of the Supreme Court in The Hague, arguing over a question that has consumed their legal teams for years: Can a court force an oil company to cut its carbon emissions?
The battle between them has already traveled through the Dutch court system twice. In 2021, a lower court made what many saw as a landmark decision, ordering Shell to reduce its emissions by 45 percent within nine years. It was a stunning victory for Milieudefensie and seemed to signal that judges were willing to impose hard numbers on fossil fuel companies. But three years later, an appeals court reversed that ruling. The higher court said Shell was already doing what the law required of it, and rather than mandate a specific reduction target, it simply told the company to make an "appropriate contribution" to the Paris climate goals—language so vague it left Shell's actual obligations unclear.
Now the case had reached the country's highest court, and the two sides were making their final arguments about what courts can and should do in the climate crisis. Milieudefensie's lawyer, Roger Cox, told the judges that they had a responsibility to act. He argued that courts were essential to holding both governments and large corporations accountable for climate harm. An order forcing Shell to cut emissions, he said, would be a significant step toward protecting human rights and the environment. The implication was clear: if courts did not intervene, who would?
Shell's lawyer, Freerk Vermeulen, offered a different vision of how the world should work. Emissions regulation, he argued, was the job of governments and international bodies, not judges. Court orders targeting individual companies would be messy, ineffective, and counterproductive. They would create legal chaos, he said, lacking the coordination and flexibility that only governments could provide. Vermeulen painted a picture of judicial overreach—judges imposing arbitrary rules on arbitrarily selected companies, creating uncertainty and inconsistency across industries.
The disagreement ran deeper than just this one case. It was about the proper role of courts in a climate emergency. Should judges be tools for enforcing climate action when governments move too slowly? Or would judicial intervention in corporate operations undermine the rule of law and the democratic process? The Paris climate agreement, signed in 2015, had committed nations to limiting warming to 1.5 or 2 degrees Celsius above pre-industrial levels. But nearly a decade later, global emissions were still rising. Milieudefensie's argument was that if courts did not step in, the agreement would remain a symbolic gesture with no teeth.
Beyond this Supreme Court case, Milieudefensie was also pursuing Shell in a separate lawsuit, seeking to prevent the company from investing in new oil and gas fields. That case represented another front in the same war—a battle over whether courts could not just regulate existing operations but actually constrain future expansion.
The Supreme Court was expected to issue its ruling sometime in the first half of 2026. Whatever it decided would likely echo far beyond the Netherlands. European courts and courts in other countries were watching. If the Dutch Supreme Court sided with Milieudefensie, it could open a new avenue for climate litigation worldwide, giving environmental groups a tool to force corporate action through the judiciary. If it sided with Shell, it would suggest that courts should stay out of emissions regulation, leaving the fight to governments and markets. The stakes were not just about Shell's bottom line or the Netherlands' climate goals. They were about who gets to decide how fast the world moves away from fossil fuels.

The Hearth Conversation Another angle on the story
Why does it matter whether a court or a government sets the emissions target?
Because a court order is binding in a way that a government promise often isn't. Governments change. Administrations come and go. But a court ruling is law. If a judge says Shell must cut 45 percent by 2030, Shell has to do it or face contempt charges.
But Shell's lawyer said courts lack the expertise to regulate emissions. Isn't he right?
He's right that courts aren't engineers. But the question isn't whether judges understand oil refining. It's whether they can read a contract and enforce it. Shell agreed to the Paris climate goals. The question is whether a court can hold them to it.
So why did the appeals court overturn the first ruling?
The appeals court decided the lower court had overstepped. They said Shell was already doing enough, even though "enough" was never clearly defined. It was a way of saying: we're not going to tell a company exactly how to run itself.
And Milieudefensie thinks that's not good enough?
They think it's a dodge. Vague language like "appropriate contribution" means nothing if there's no way to measure it, no way to enforce it. They want numbers.
What happens if the Supreme Court says no?
Then climate activists lose a major tool. They'd have to go back to lobbying governments, which move slowly. And Shell gets to keep operating largely on its own terms.
And if the Supreme Court says yes?
Then every major corporation in Europe has to worry about being sued by environmental groups. It changes the calculus entirely. Suddenly courts become a way to force climate action when politics can't.
