Summary:
On 21 April 2026, the Dutch NGO Milieudefensie delivered summons to oil and gas giant Shell Plc, in its second collective legal action against the company following the first Milieudefensie case (decided on appeal in 2024). This second case, under Section 3:305a of the Dutch Civil Code (DCC), is brought on behalf of current and future generations of Dutch citizens after the corporate actor moved its seat from the Netherlands to the United Kingdom. Milieudefensie summoned Shell to appear at a hearing to be held at the District Court of Amsterdam on 29 July 2026.
In its 273-page summons, Milieudefensie covers issues of jurisdiction, the requirements for a collective suit under Section 3:305a DCC, the scientific evidence underpinning its case, the risk of reaching climate tipping points for Europe and for the Netherlands, international climate policy and the global 1.5-degree temperature target, the important role played by non-state actors and their corporate responsibilities to respect human rights, the inhibiting influence of the oil and gas industry, including Shell, on infrastructural carbon lock-ins, including through its historical undermining of climate science and strategies to delay climate action, as well as its lobbying against the EU’s Corporate Sustainability Due Diligence Directive (CSDDD or CS3D) of 13 June 2024.
Milieudefensie sets out the framework for assessing Shell’s responsibility under Sections 3:296 and 6:162 DCC, fleshing this out by invoking the societal duty of care under domestic law, as well as the doctrine of hazardous negligence, human rights law (particularly Articles 2 and 8 ECHR, the rights to life and respect for private and family life), international customary law, international soft law, and legal principles including the precautionary principle, the climate law principle of Common but Differentiated Responsibilities (CBDR), and the principle of intergenerational justice. In particular, the summons argues that
“[s]ince the Urgenda judgment, it has been widely recognised in court judgments that dangerous climate change leads to human rights violations. Not only the ECHR, but also the IACtHR and the ICJ have recently found this. Numerous (supreme) national courts have independently reached the same conclusion. Within Europe, for example, reference can be made to the case law of the [German] Bundesverfassungsgericht and the Court of Appeal in Brussels. Outside Europe, the situation is no different. For example, the Lahore High Court in Pakistan, the Supreme Court of Colombia, the Brazilian Federal Supreme Court, the District Court of Montana (United States) and the Supreme Court of India have all ruled that human rights can be relied on in order to be protected against the effects of climate change. In view of the above, there can be no misunderstanding that human rights (indirectly) have a horizontal effect when the unwritten duty-of-care standard is fleshed out. Nor can there be any debate about the fact that dangerous climate change leads to human rights violations and that human rights can be relied on for protection against dangerous climate change. The only question that remains is what assessment framework needs to be applied here. “
Milieudefensie argues that Shell bears a share of the responsibility to prevent dangerous climate change, discussing its level of knowledge and the foreseeability of harm by arguing that Shell has long known about the fact that fossil fuels cause climate change, with serious consequences for people and the environment, has known that it is making a substantial contribution to climate change and that it needs to take (precautionary) measures. It sets out Shell’s two-pillared obligations: first, a reduction obligation for Scope 1, 2 and 3 CO2 emissions, and second, an obligation not to develop new oil and gas fields.
Concerning the first pillar of obligations, Milieudefensie argues that “Shell must make an equitable contribution (a “fair share”) to preventing dangerous climate change and limiting global warming to 1.5°C by reducing its emissions.” In doing so, it invokes UN reports to argue that:
- companies must demonstrate maximum ambition to achieve (net) zero CO2 emissions as quickly as possible, but by 2050 at the latest;
- companies must set ambitious and credible interim targets for the short and medium term on the road to the above-mentioned goal of net zero CO2 emissions that represent a fair share of the global reduction target; and
- the (interim) targets should cover all Scope 1, 2 and 3 emissions and should aim for absolute CO2 emission reductions.
It also submits that “Shell can be considered to be an influential Western company in several respects; it has both substantial emissions and large transition capabilities and a large historical responsibility. These are all relevant circumstances under the above-mentioned climate protocols (as evidenced by e.g. the reference to the CBDR principle and the need to take on a fair share of the global target) for asking Shell to take on an above-average responsibility and requiring it to reduce its emissions faster than the global average.”
As concerns the second pillar of obligations, Milieudefensie argues that Shell’s obligation not to pursue new fossil fuel projects is “based on the doctrine of hazardous negligence, human rights law, the legal principles discussed, soft law and other objective points of reference, is that Shell must cease the development and production of new oil and gas fields. After all, the carbon budget with a 50% probability of 1.5°C is already exceeded with the operation of the existing fossil-fuel infrastructure alone, and new oil and gas fields are therefore incompatible with the goal of limiting global warming to 1.5°C by the end of this century. “
Milieudefensie concludes that Shell is breaching its societal duty of care under domestic law, and seeks the following provisionally enforceable remedies:
- Emissions reductions, covering annual Scope 1, 2 and 3 emissions, as per the table below;

- A prohibition of achieving these reductions through divestment, i.e. through transfer of shares or assets;
- To prohibit Shell from making use of carbon credits for the purpose of achieving the emission reductions described;
- To order Shell to achieve that the Shell Group ceases, continues to cease and does not start the production of new oil and gas from fields.
