Tomorrow, 22 May, the Dutch Supreme Court in The Hague takes up one of the most consequential legal questions of our time: can a major fossil fuel company be legally compelled to reduce its emissions in line with climate science and human rights law?
The case is Milieudefensie v. Shell, and its outcome will matter far beyond the Netherlands.
A case years in the making
The litigation began when Dutch environmental organisation Milieudefensie, together with co-plaintiffs representing present and future generations, brought Shell to court over its contribution to dangerous climate change. In 2021, a district court issued a landmark order requiring Shell to cut its emissions by 45% by 2030. Shell appealed. In November 2024, the Court of Appeal in The Hague confirmed a critical principle: Shell and other large polluting companies have a duty to protect human rights, must make an adequate contribution to the Paris climate goals, and cannot hide behind existing regulation to avoid their individual responsibilities. The appeals court also recognised that new oil and gas fields could conflict with the Paris Agreement, and that companies bear responsibility not only for their own operational emissions but also for those generated by the use of their products. What the appeals court declined to do was set a specific, measurable reduction percentage for Shell. That gap – between acknowledged responsibility and enforceable obligation – is precisely what Milieudefensie is now asking the Supreme Court to close.
Why the Supreme Court hearing matters
The Dutch Supreme Court’s ruling will be final. No further appeal is possible. Three questions sit at its heart:
First, does the right to effective protection from dangerous climate change require courts to set concrete, measurable targets – not just acknowledge that a duty exists? Second, can courts look beyond narrow scientific consensus to international climate agreements and legal principles when determining what a company must do? Third, is Milieudefensie’s interest in a specific reduction order legitimate, regardless of how Shell might choose to implement it?
These are not abstract legal puzzles. They determine whether climate litigation can deliver real accountability, or whether corporations can satisfy a court by acknowledging responsibility while continuing business as usual.
What this means for advocacy and democracy
At The Good Lobby, we pay close attention to cases like this – not only because of the climate stakes, but because of what they reveal about the relationship between law, power, and democratic accountability. Corporate lobbying has long shaped the political environment in which climate regulation is made and weakened. Courts are increasingly being asked to fill the gap left by legislative inaction or backsliding. Milieudefensie v. Shell tests whether judicial accountability can be a meaningful complement to the political process, and whether citizens and civil society organisations have the standing to enforce it. A strong ruling from the Dutch Supreme Court would send a clear signal globally: corporate climate responsibility is not a PR commitment. It is a legal obligation, and it is enforceable.
The hearing takes place on 22 May. We will be following developments closely. Whatever the outcome, this case has already reshaped the legal landscape: it has established that protection from climate change is a human right, that large companies bear independent responsibility for their emissions, and that courts are not obliged to defer to polluters. The question now is how far accountability can reach – and how fast.
