The Hague District Court held that the Dutch State’s mitigation and adaptation measures concerning Bonaire fall short of the Netherlands' obligations under the UN climate framework and violate Articles 8 and 14 ECHR. The Court found that the State’s current approach fails to adequately protect the private and family life of Bonaire’s inhabitants from climate-related risks. Without prescribing specific figures, the Court ordered the State to incorporate economy wide absolute emission reduction targets, including interim targets up to 2050, into national legislation and to draw up and implement a national adaptation plan covering Bonaire by 2030.

Background and summary of the Court’s orders

On 28 January 2026, the District Court of The Hague (the Court) delivered its judgment in proceedings brought by Greenpeace Netherlands against the State of the Netherlands (the State) concerning climate mitigation and adaptation measures affecting the inhabitants of Bonaire (the Judgment).^[1] The Judgment is a first-instance decision and may be overturned on appeal.^[2]

Bonaire – an island in the Caribbean and formerly part of the Netherlands Antilles – became part of the country of the Netherlands in 2010. It has Overseas Country and Territory status, meaning that EU law does not apply to Bonaire in principle (§5.36–5.36.3).

Greenpeace argued that the State has not taken sufficiently timely and appropriate measures to protect Bonaire’s inhabitants from the effects of climate change and that Dutch mitigation policy does not reflect the equitable contribution required under the UN climate regime to pursue the 1.5°C temperature goal (§1.1–1.6; §8.1). It sought, among other relief, accelerated net-zero reduction orders, an adaptation plan by 2027, and the establishment of a Dutch carbon budget (§8.1).

The Court granted the claims in part. It declared that the State has acted and continues to act in violation of Article 8 ECHR towards the inhabitants of Bonaire and is therefore acting unlawfully (operative part §12.1). It also declared a violation of Article 14 ECHR and Article 1 of Protocol 12 ECHR due to unjustified differential treatment of the inhabitants of Bonaire compared with inhabitants of the European Netherlands (operative part §12.3).

The Court ordered the State to:

• within 18 months, incorporate absolute emission reduction targets for the entire economy into national legislation, including intermediate targets and pathways through to 2050 that comply with UN agreements (including Glasgow and Sharm el‑Sheikh), and to clarify the Netherlands’ (remaining) emission allowance (operative part §12.2; see also §11.14.2, 11.58); and
• ensure that, by 2030, the UAE Framework for Global Climate Resilience targets for drafting and implementing a national adaptation plan – also covering Bonaire – are met (operative part §12.4).

The orders are provisionally enforceable, meaning they must be implemented by the State pending a potential appeal (operative part §12.7; §11.61–11.62).

Key findings

1. Each State bears its own responsibility when it comes to climate action

The Court noted that the Netherlands, as an Annex I country (a wealthy and developed country) under the UNFCCC, has international commitments under the UN climate regime, including the Paris Agreement, directed at limiting global warming to 1.5°C. As discussed further below (section 3), the Court treated these UN climate commitments as an important benchmark for assessing whether the State has met its positive obligations under Article 8 ECHR.

The Court considered that climate cases are fundamentally different from other environmental cases given the cumulative and transboundary nature of climate harm and the seriousness of its consequences for present and future generations (§9.3–9.5).

In that context, the Court held that the State cannot avoid its own responsibility to take measures against climate change by pointing to (i) its relatively small share of global emissions, (ii) the limited marginal impact of its measures, or (iii) insufficient action by other States. The Court's approach aligns with the ECtHR’s confirmation in KlimaSeniorinnen that each State bears responsibility for its own share of climate action (§9.4-9.5; referring to KlimaSeniorinnen §442, see our blog on KlimaSeniorinnen here).

In addition to relying heavily on KlimaSeniorinnen, the Court referred to the ICJ Advisory Opinion of July 2025 on States’ obligations under international law in relation to climate change, including the distinction between obligations of conduct and result (§5.26, see our blog on the ICJ Advisory Opinion here). The Judgment, though subject to appeal, thereby forms a further addition to the body of “State responsibility” climate law.

2. KlimaSeniorinnen “overall assessment”

The Court assessed Greenpeace’s claims using the “overall assessment” from KlimaSeniorinnen, which comprises mitigation measures, adaptation measures and procedural safeguards. It emphasised that mitigation and adaptation cannot be evaluated in isolation (§1.6; §10.24.2–10.24.6; §11.1). The Court also stressed that not every arguable deficiency within that overall assessment necessarily amounts to a standalone violation of the ECHR and/or an unlawful act (§1.6; cf. §10.24.3).

Before proceeding with a substantive assessment of the claims, the Court held that Greenpeace had not established, at a collective level, an acute life‑threatening situation engaging Article 2 ECHR. It considered that risks and impacts differ depending on where people live on Bonaire as well as their health, age and socio‑economic circumstances, and on future adaptation measures (§11.3–11.3.4). Nevertheless, the alleged harms were sufficient to engage Article 8 ECHR, which covers longer-term threats to life expectancy, health and wellbeing (§11.3.2–11.3.4). The right to live and practise one’s own culture under Article 27 ICCPR was deemed protected by Article 8 ECHR (§10.6).

In determining whether Article 8 ECHR was violated, the Court identified several mitigation-related concerns as part of its “overall assessment”:

• Binding targets and pathways: the Court considered that Dutch legislation lacks concrete and coherent instruments to achieve its internationally agreed emission reduction targets for the period between 2030 and 2050 (§11.14.2; 11.17; operative part §12.2).
• Implementation of climate measures: the Court referenced the Netherlands Environmental Assessment Agency’s assessment that it is “highly unlikely” the Netherlands will achieve its 2030 target on current policy (§6.6; 11.14.1), treating this as relevant to whether the State's current climate policy is capable of achieving the 2030 goal.
• Clarity on the Netherlands’ remaining emissions allowance: while the Court did not require adoption of a national carbon budget per se, it ordered the State to clarify the (remaining) emission allowance on which Dutch climate policy is based, consistent with transparency expectations in the UN context (§11.15.1–11.15.6; 11.58; operative part §12.2).

3. UN climate commitments and standards used as the benchmark for minimum expectations

The Court’s assessment of the State’s compliance with positive obligations under Article 8 ECHR is explicitly benchmarked against the commitments of Annex I countries under the UNFCCC, as well as subsequent COP outcomes such as the Paris Agreement, the Glasgow Climate Pact, the Sharm el‑Sheikh Implementation Plan and the UAE Framework for Global Climate Resilience (see, e.g., §11.9–11.11; operative part §12.2 and §12.4). In particular, the Court referred to benchmarks such as the 43% reduction of all greenhouse gases by 2030 relative to 2019, as reflected in the Sharm el-Sheikh Implementation Plan, which articulates a global emissions trajectory, when evaluating the adequacy of Dutch mitigation and adaptation measures and the State's compliance with its duty of care.

4. Unequal treatment

While the State argued that Bonaire’s circumstances differ materially from those of the European Netherlands, the Court held that equal treatment does not require identical measures (§11.38–11.44). However, it concluded that the State had taken mitigation and adaptation measures for Bonaire later and less systematically than for the European Netherlands, despite long-standing knowledge that Bonaire would experience serious adverse effects earlier and that local authorities lacked sufficient capacity (§1.5; 11.46). In the Court’s view, those differences pointed to greater urgency. The State had not sufficiently explained why the different timing and approach were appropriate, necessary and proportionate (§11.46), leading to a finding of unequal treatment in breach of Article 14 ECHR (read with Article 8) and Article 1 of Protocol 12 ECHR (§11.39–11.48; operative part §12.3).

Implications

1. Holistic approach to emissions reductions

The Court held that, under the UNFCCC, climate policy and measures must be economy-wide and cover all relevant sources.^[3] It highlighted that aviation and shipping are currently not fully included in the Dutch greenhouse gas emission reduction targets (nor in the EU NDC), despite significant emissions from these sectors in the Netherlands – for example from Schiphol Airport and the Port of Rotterdam (§11.13.3).

The increased scrutiny of emissions reductions across sectors underscores the holistic lens through which the Court evaluated the State’s climate policy. In practice, this may prompt governments to also take a more holistic approach in their climate policy and set targets across all sectors. They will need to take into account that certain sectors are harder to abate (meaning that emissions reductions are less easily achieved than in others), such as the transport sector where it concerns shipping, aviation and heavy-duty trucking.

2. Potential tension with EU climate legislation

The Court found that the EU Emissions Trading System Directive^[4] (ETS), Effort Sharing Regulation^[5] (ESR), Land Use, Land-Use Change and Forestry Regulation^[6] (LULUCF), and the Governance Regulation^[7] – which the State invoked to demonstrate that the emissions on Dutch territory are already being regulated and quantified – do not set out concrete reduction measures for the post-2030 period. In addition, the EU’s NDC does not clearly disclose the underlying carbon budget and the EU has not communicated a breakdown of emission budgets per Member State to the UNFCCC (Judgment §11.15.3). As a result, according to the Court, the Netherlands’ emissions for 2030–2050 are not quantified with sufficient clarity as required by the UN framework (§11.15.4–11.15.5). The Court further noted that there is a “strong indication” that the European reduction standards are lower than the UN minimum standards for Annex I countries and added that if the EU’s climate contribution does not satisfy these standards, the Netherlands might have to submit its own NDC under the Paris Agreement (§11.13.3, 11.15.3, 11.15.4 and 11.16). The Court also observed that both the Dutch Climate Act and the European Climate Law^[8] base their 2030 targets on a 1990 baseline rather than the 2019 baseline referred to in recent UN standards, and that the Dutch Climate Act deviates from the European Climate Law by treating the 55% reduction by 2030 as a target figure rather than a binding objective (§11.13.2).

These findings give rise to several questions, in particular whether the Court should have considered more explicitly whether its interpretation of the Dutch Climate Act risks interfering with certain principles of EU climate legislation. Notably, the 55% target in the European Climate Law is an EU‑wide target. It does not require Member States to enact an identical national target, and it is supported by implementation mechanisms, including the submission and progressive strengthening of National Energy and Climate Plans. Relatedly, the Court’s criticism of the EU’s and the Netherlands’ use of a 1990 baseline appears to overlook the practical effect of the targets: a 43% reduction by 2030 relative to 2019, which the Court draws from the Sharm el‑Sheikh Implementation Plan as its benchmark, would – for the Netherlands – translate into a less stringent absolute emissions outcome than a 55% reduction by 2030 relative to 1990.^[9]

Moreover, the Court does not appear to fully engage with the intentional interaction between the ETS, ESR and LULUCF: these instruments avoid double counting while allowing a limited degree of interchangeability. For example, the ESR permits certain Member States to cancel a limited number of ETS allowances and receive equivalent ESR allocations, and allows limited LULUCF credits to be used towards ESR compliance. Against that backdrop, the Court’s orders require the State to implement a national, economy‑wide layer to its emission‑reduction efforts, which will need to be carefully integrated within this existing EU sectoral climate architecture. To the extent that the Court’s reasoning may be read as casting doubt on the adequacy of the European Climate Law and related instruments in light of the UNFCCC and the Paris Agreement, it also raises the question whether preliminary questions ought to have been submitted to the Court of Justice of the European Union.

3. Legislative orders and separation of powers

In line with the Dutch Supreme Court’s Urgenda judgment in 2019, the Court recognised that it could determine what the State is required to do under binding legal standards. However, it cannot require the legislature to enact laws with a predetermined “specific content”, as such matters fall exclusively within the realm of legislative and political decision-making, nor can it issue legislative orders that would create regulations affecting parties beyond those involved in the case. On the other hand, the Court may impose orders to achieve specified objectives, as long as they allow flexibility in the choice of means (§11.53). In practice, the highly detailed nature of the Bonaire Judgment's orders leaves the State with limited flexibility in how they are implemented. This prompts consideration of what constitutes a 'legislative order' and suggests that the State may face demands for similarly specific orders in future legal actions.

⁹ By way of illustration, Dutch greenhouse gas emissions were 226.6 MtCO₂e in 1990 (Source: Emissieregistratie Rijksoverheid); a 55% reduction by 2030 (relative to 1990) would imply an allowable 2030 emissions level of approximately 102 MtCO₂e. In 2019 emissions were 180.7 MtCO₂e (Source: Compendium voor de Leefomgeving); a 43% reduction by 2030 (relative to 2019) would imply an allowable 2030 emissions level of approximately 103 MtCO₂e.
