Greenpeace Finland & the Finnish Association for Nature Conservation v. Government of Finland

Summary:

Greenpeace Finland and Finnish Association for Nature Conservation have sought judicial review by the Finnish Supreme Administrative Court of the government’s plans for implementation of climate targets under the 2022 Climate Act. These plans are detailed in the Government Report on the National Energy and Climate Strategy and Medium-Term Climate Plan, both of which were issued in December 2025. The plaintiffs argue that the measures envisaged by the government are insufficient to achieve the targets set out in the Climate Act, and alternative pathways towards the achievement of the targets have not been assessed, and thus the government is in breach of its statutory duty.    

The plaintiffs have approached the highest administrative court in Finland directly (rather than via the appellate route), arguing that the impugned government decisions implicate civil rights and obligations as interpreted by the European Court of Human Rights in the Verein KlimaSeniorinnen & Others v. Switzerland judgment.

Community Representative of San Bartolo Coyotepec v. State of Oaxaca

Summary:
On 11 March 2024, a representative of the community of San Bartolo Coyotepec in Mexico’s State of Oaxaca filed an amparo petition with the Ninth District Court of the State of Oaxaca, arguing that the human right to a healthy environment had been violated because municipal, state, and federal authorities had failed to protect Benito Juárez National Park and the corresponding Ecological Reserve and Protected Natural Area. On 20 March 2025, the case was rejected by the Ninth District Court given the failure to demonstrate a concrete, direct, and imminent harm resulting from the alleged failure to protect the designated areas.

The applicant appealed, arguing that the first instance judge had failed to reason his decision, had shifted the burden of proof to his detriment, and had improperly evaluated the evidence concerning the progressive deterioration of the protected natural areas in question.

On 20 October 2025, the Supreme Court of Justice of Mexico accepted the case for review. On 24 February 2026, the Plenary Session of the Supreme Court of Justice ordered that the case be remanded to the Ninth District Court to amend the ruling that denied constitutional protection, gather evidence and determine whether the applicant’s human right to a healthy environment had been violated. It established that, pursuant to Article 4 of the Mexican Constitution, which enshrines the right to a suitable environment, any person who inhabits or uses an ecosystem and benefits from its environmental services may go to court to demand its protection, without needing to prove direct individual harm.

In doing so, the Court explicitly linked the case to climate change. It noted the interconnectedness of the three aspects of the ‘triple planetary crisis’ (climate change, biodiversity loss and pollution), and held that none of these aspects can be treated in isolation from each other. It noted the applicant’s framing of the territory in question as a carbon sink. It also extensively cited the 2025 advisory opinions on climate change of the International Court of Justice and the Inter-American Court of Human Rights (IACtHR). It particularly emphasized the IACtHR’s finding that “urged States to maximize the scope of protection of the right to the environment, recognizing that this right protects not only individuals, but also the components of the environment—such as forests, rivers, seas, and other ecosystems—as autonomous legal interests, even in the absence of certainty or immediate evidence of a direct risk to specific individuals” (para. 43). In doing so, it noted that according to the IACtHR climate change poses an imminent risk to life, health, food security, and the balance of ecosystems on a global scale (para. 42), as well as extensively citing the ICJ’s discussion of the right to a healthy environment in its climate advisory opinion (para. 35).

With this decision, the Court reaffirmed the “adjacent environment” doctrine in environmental matters. This means that individuals who live in or use the area of influence of an ecosystem and receive its environmental benefits may file an amparo petition, even if they do not live immediately adjacent to the Protected Natural Area. Furthermore, the Court noted that environmental protection must be analyzed in accordance with the precautionary principle, meaning that the absence of scientific certainty regarding the benefits of the ecosystem in question cannot be used to deny its protection or to disregard the relationship between people and the natural environment.

Climate Action Professionals Zambia v. Attorney General of Zambia

Summary:

Climate Action Professionals Zambia (CAPZ) is a non-governmental organisation consisting of young professionals and students advocating for climate change redress in Zambia. CAPZ filed a petition on 31 October 2025 against the Attorney General of Zambia challenging the state’s alleged failure to implement the key climate governance mechanisms envisaged by the Green Economy and Climate Change Act 18 of 2024 (GECCA). The GECCA mandates the state to establish key climate governance mechanisms to address climate change effects in the country. The GECCA was enacted on 20 December 2024, published on 26 December 2024, and came into force on 10 October 2025. The key climate governance mechanisms which the GECCA envisages include national adaptation and mitigation plans, a greenhouse gas inventory management system, and a green economy and climate change fund, amongst others.

In the petition, CAPZ argued that in spite of the GECCA’s entry into force, the state had failed to establish or implement several of the mechanisms envisaged by the GECCA, and thereby violated Article 257(g) of the Zambian Constitution which provides: ‘the State shall, in the utilisation of natural resources and management of the environment (…) establish and implement mechanisms that address climate change.’ CAPZ sought relief in the form of a declaratory order stating that the state had violated Article 257(g), as well as a mandatory order ordering the state to establish and implement the mechanisms within a given time period.

The Attorney General opposed the petition on the ground that neither the Constitution nor the GECCA imposed an immediate obligation to realise the mechanisms upon the GECCA’s entry into force. The Attorney General argued that Article 257(g) is directive in nature, requiring progressive implementation subject to capacity and resources, and the incomplete operationalisation of certain mechanisms does not amount to constitutional non-compliance. The Attorney General also raised a separation of powers concern, stating that the point of question in the matter concerned policy and administrative matters, and not constitutional interpretation.

The Constitutional Court decided the case on 25 March 2026 and dismissed the petition for lack of jurisdiction. The Court characterised the specific mechanisms at issue as being within the realm of statutory implementation, not constitutional obligations. Being a matter of statutory compliance, rather than constitutional compliance, it should have been brought before the ordinary courts rather than the Constitutional Court.

Kaarina Dunn et al. v. Public Service Comission of Wisconsin, et al.

Summary:
On 23 April 2026, a court in the US state of Wisconsin ruled in a youth climate case against the Wisconsin Public Service Commission and the Wisconsin State legislature. The case was filed by fifteen young people ranging in age from 8-17. The youth plaintiffs had challenged the constitutionality of statues governing the approval of fossil fuel-fired power plants because those statutes limit the ability of the first respondent, the Public Service Commission of Wisconsin, to consider air quality impacts of when issuing permits for such plants. In doing so, they had invoked their rights, under the Wisconsin state constitution, to liberty and to life, as well as the rights to a stable climate system and to access, enjoy and use navigable waters (both of which they considered inherent within the constitution). They also alleged a violation of Wisconsin’s public trust doctrine.

According to the Plaintiffs, climate change has rendered them unable to enjoy Wisconsin’s natural resources, like its rivers and lakes, as well as prevented them from engaging in recreational activities, like swimming and skiing. Some are deprived of their Indigenous cultural traditions, while others have experienced asthma and contracted Lyme disease.

The judge tasked with resolving this case, Judge Julie Genovese, ruled that “[w]hile the court is sympathetic to the youths and admires their willingness to access the courts in their quest to protect the planet, I conclude that the case must be dismissed because environmental policy is a nonjusticiable political question”. The judge discussed Wisconsin’s political question doctrine, which “dictates that courts will not decide questions that require the court to determine what the best or wisest public policy would be”, and “also embodies a practical component, recognizing that matters of economic and social policy are not reasonably “susceptible to judicial management or resolution.””

The judge concluded that:

“by substituting this court’s judgment for the legislature, the court
would be showing a lack of respect for the legislative and executive branches. Plaintiffs do not like these policy decisions. (…) Because Plaintiffs think it is technologically and economically feasible for Wisconsin to be carbon free by 2050, they conclude that by invalidating the statutes and thus their limitations, the PSC will decide to stop approving fossil fuel-fired plants, and Plaintiffs’ carbon free goal will be achieved. While the court may agree with Plaintiffs’ policy preferences, it would show a blatant lack of respect for our elected officials and the agency defendants to substitute my judgment for theirs, and strike the limitations imposed by the legislature and executed by the PSC. Accordingly, because the court concludes that the legislature’s policy decisions represent a nonjusticiable political question, this case must be dismissed.”

Aurora v. Sweden (Aurora Case II)

Summary

On 6 February 2026, the youth-led association Aurora launched a climate lawsuit before the Nacka District Court against the government of Sweden alleging a violation of their rights to life, health and well-being as well as the prohibition of discrimination (based on age). The case is a follow-up to Anton Folley and Others v. Sweden (Aurora Case). That case was a class action suit brought by over 600 young individuals (supported by Aurora), which the Supreme Court of Sweden dismissed as inadmissible on the ground that the plaintiffs did not meet the high threshold for individual victim status articulated by the European Court of Human Rights in the Verein KlimaSeniorinnen et al. v. Switzerland judgment.

Relying upon the criteria for ‘victim status’ and the standing of associations to litigate climate cases laid down in Verein KlimaSeniorinnen, Aurora argues that this fresh case is admissible and that the district court may proceed to examining the substantive claims.

Claims:

The substantive claims in Aurora II are largely the same as the claims which were made in the Aurora case, with the new petition drawing upon more recent climate jurisprudence, including the ICJ’s Advisory Opinion on the Obligations of States in respect of Climate Change to support its case. In the petition, Aurora identifies a lack of measures or intermediate emission reduction targets envisaged for the period after 2030, and problematizes Sweden’s emissions debt (i.e. the exceedance of its national fair share of the global carbon budget) as failures to exercise due diligence in the discharge of positive obligation to protect individuals who Aurora represents from serious threats to the enjoyment of their rights. The petition also invokes the findings of the IPCC to argue that children and youth, who Aurora represents (majority born between 1998 and 2026), are at a particular risk from climate change, in order to demonstrate the disparate impact of Sweden’s failure to effectively contribute towards climate mitigation. The petition requests the court to handle the case with urgency, to declare violations of Articles 2, 8 and 14 and an order the government to pay legal costs incurred by the plaintiffs.

Response from the State

In June 2026, the Swedish government responded to the case. It agreed that the Aurora case should be heard on its merits, but argued that Sweden action on climate change is already sufficient to protect human rights. This means that the case will now move to examination by the district court, which will determine whether Sweden’s overall climate efforts are sufficient to protect human rights from the effects of the climate crisis.

Bonaire Climate Case: Creative or Questionable Interpretation of International Climate Law?

Pranav Ganesan, PhD Candidate at the University of Zurich

The Greenpeace Netherlands v. State of the Netherlands (Bonaire) judgment of the Hague District Court has stolen the limelight as the new posterchild for strategic climate litigation. The plaintiff in this case, Greenpeace Netherlands, argued that the Dutch government failed in its duty to protect the residents of Bonaire, an island in the Caribbean which formally attained the status of a special municipality of the Netherlands in 2010. Although it is a special municipality (bijzondere gemeente), it is just as much a part of the Netherlands as any other province in the European Netherlands. The Dutch government owes obligations under international human rights law, including those arising from the European Convention on Human Rights (ECHR), towards residents of the municipality. That international human rights law requires states to undertake climate mitigation measures and adaptation measures, as informed by international climate change law where relevant, has been affirmatively held in two advisory opinions from international courts and the European Court of Human Rights. And the proposition that the Dutch government’s duty of care towards its population essentially includes obligations under the ECHR was confirmed by the Supreme Court of the Netherlands in Urgenda. Thus, it comes as no surprise that in material respects, the Hague District Court’s reasoning was so heavily based on international law.[1] In terms of the scope of state conduct implicated in this case, it outdoes the Urgenda case,which only concerned contributions to the mitigation of climate change. The Hague District Court agreed with the plaintiff that the Dutch government had violated Article 8 ECHR as well as the prohibition of discrimination (Art. 14 ECHR and Art. 1 of Protocol No. 12 to the ECHR), the former due to inadequate mitigation measures, inadequate implementation of those measures, delays in adopting an adaptation plan for Bonaire and late provision of procedural safeguards to the residents of Bonaire. In this blog, I provide a quick analysis of the District Court’s engagement with the UN Framework Convention on Climate Change and Paris Agreement in the section on mitigation measures. Readers interested in learning about the adaptation component and how the court addressed discrimination claim are welcome to read this blogpost by Wewerinke-Singh.

There are areas in the judgment where the District Court’s assessment of the compatibility of the Dutch Climate law framework with international climate law is questionable. The first glaring issue is that the court made a finding of non-compliance with Article 4(4) of the Paris Agreement based on the absence of ‘absolute emissions reduction targets’ in the Dutch Climate Act of 2019 (para 11.13.1). The problem identified by the court was that the targets were expressed as goals that the government would ‘strive to achieve.’ However, this does not mean that the targets are not absolute. The difference between absolute and relative emissions reductions targets being whether they are expressed as percentage reductions in comparison to the emissions during a fixed baseline year, as opposed to reductions from a business as usual scenario in case of relative targets (Winkler et al 2014, 636). The use of the expression ‘strive to achieve’ means that the nature of the obligation to achieve the target is one of conduct rather than result, reflecting the nature of the obligation to pursue domestic mitigation measures in pursuance of NDCs communicated under Article 4(2) of the Paris Agreement (ICJ Advisory Opinion, paras 251-253). Another connected example is the court’s declaration that ‘UN standards’ require emission reduction targets to be expressed as percentage reductions to be achieved by the target date, in comparison to 2019 levels as opposed to the 1990 baseline (para 11.13.2). Moreover, strictly speaking, Article 12(8) of the UNFCCC does not require the EU to provide information about each member state’s national carbon budget like the court suggests (para 11.15.3). The court’s interpretation of these treaty provisions might be technically imprecise, but it is undoubtedly bold, being based on the need for exemplary efforts from a developed country like the Netherlands, and reflecting the appropriate sense of urgency in light of the results of the First Global Stocktake (para 11.9.4). Through its interpretive moves, the court effectively hardened ‘soft’ obligations (i.e. normative expectations) sourced from the Paris Agreement and COP decisions (on hard and soft obligations in the Paris Agreement, see Rajamani, 2016).

A final noteworthy aspect of the judgment is the rather detailed response to how the notion of ‘equity’ in Article 3(1) of the UNFCCC and Articles 2(1) and 4(1) of the Paris Agreement is to be applied in reviewing states’ mitigation commitments. Equity is an elusive concept, with debates on what an equitable distribution of the global emissions reduction burden entails having remained unsettled since the inception of international negotiations on the topic of climate mitigation (Oliver Herrera et al, 2025). The court provided the (un)acceptability of a ‘grandfathering approach’ as an example of one such debate (para 11.13.5). But it did not go so far as to hold that the grandfathering approach is legally impermissible because it is inequitable per se, or that an equal per capita emissions approach is the minimum standard under international law. Rather, it assessed the Netherlands’ policy negatively on account of its failure to justify why its current policy, which is based on the controversial grandfathering principle and falls short of the ambition required by the equal per capita emissions approach, is equitable in accordance with Article 3(1) of the UNFCCC and Article 4(1). It thus did not use equity to dictate the outcome of what exactly the Dutch government’s fair share of the global carbon emissions ought to be. At same time, it did not use the underlying controversy as a reason to entirely avoid reviewing the substance of the Dutch climate mitigation policy. This is underscored by its remedial findings, wherein the court declared that the Netherlands’ current mitigation commitments were inequitable, thereby leading to a breach of Article 8 (para 12.1), but dismissed Greenpeace’s request ordering the adoption of specific emissions reduction targets by the government, or at least a carbon budget reflecting the ‘equal per capita emissions approach’ (paras 8.1 (IV)-(VI), 11.55 and 11.58).

Overall, the Bonaire judgment shows how climate litigation can lead to precarious precedents. On the one hand, the way the Court engaged with the concept of equity provided an assessment of Dutch mitigation ambition which was notably pragmatic and might serve as inspiration for other courts when asked to answer the fair share question. On the other hand, the judgment risks signaling to states that legal texts—which negotiators toiled to craft in ‘constructively ambiguous’ terms—may be stretched by domestic courts to uncomfortable extents. Ultimately, the appellate court’s scrutiny of this case (should the Dutch government file an appeal) will reveal how this judgment will be remembered: whether it will be hailed for its boldness or criticized for its questionable interpretation of international treaties.


[1] André Nollkaemper commented: ‘Today’s judgment of the District Court of The Hague fully lives up to the reputation of Dutch courts as strongly international law-minded. […] The conclusion is firmly anchored in international law. With 29 references to the ICJ Advisory Opinion on Climate Change, 64 references to the European Court’s KlimaSeniorinnen judgment, 64 to the UNFCCC, 62 to the Paris Agreement, and 12 to COP decisions, this surely ranks high on the list of climate change cases that are most shaped by international law.’
