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.

Tétaz v. Canton of Valais

Summary:
On 27 May 2026, a case was brought against the Swiss canton of Valais concerning its liability for the Blatten landslide disaster, which took place one year previously, on 28 May 2025. On that date, the collapse of the Birch glacier destabilized the mountainside above the village, the Petit Nesthorn, causing a landslide of ice, mud, and debris that buried 90% of the village of Blatten in Valais’s Lötschental valley. Although the residents of the village were evacuated, the events resulted in one death. In addition, 130 houses as well as the local church were swept away and buried under debris 200 m thick.

One year after the disaster, legal collective “Avocat.e.s pour le Climat” brought a case on behalf of Jean-Marc Tétaz, a philosopher and theologian who lost his home and his life’s work, a library comprising 5000 sources, as well as ongoing research work and handwritten family memoirs, in the disaster. In a conciliation request filed with the municipal court of Sion, he claims the balance of damage not covered by liability insurance, including for the loss of his books, manuscripts, and work notes, as well as lost earnings from publishing projects that cannot be completed. The damage claim amounts to 211,900 Swiss Francs.

The case reportedly argues that the canton of Valais failed act to avoid the disaster or provide information to the public despite having been aware of the risks since 2022, when an “imminent danger” was identified, with a collapse deemed “very likely”, by scientists from the Swiss Federal Institute for Forest, Snow and Landscape Research, who modeled the potential consequences of a landslide at the Petit Nesthorn. According to the plaintiff in this case, the canton of Valais dismissed the scientists’ finding and failed to inform local residents of the dangers, which would have allowed him to relocate his library.

The plaintiff links the glacial instability and permafrost thaw that caused the Blatten disaster with climate change, citing scientific studies that identify climate change as having a role in the disaster. He argues that the cantonal government negligently ignored the risks given its lack of an ambitious climate policy.

More information on this case, and its legal foundations, will be added when it becomes available.

Adaptation Domestic court France Paris Agreement Private and family life Right to life Vulnerability

Urgence Maisons Fissurées Sarthe et al. v. France

Summary:
On 7 April 2025, a group of five individuals litigants and nine civil society organisations presented a request for adaptation measures to the French authorities. Building on GHG emissions reductions litigation, including the ECtHR’s 2024 KlimaSeniorinnen case, this legal action seeks adaptation measures by the French government. The litigants, who are supported by Oxfam France, Notre Affaire à Tous, and Greenpeace France, seek a revision of the third National Plan for Adaptation to Climate Change (PNACC 3) and, more broadly, the adoption of any useful measures to ensure or reinforce France’s adaptation to the effects of climate change. The action argues that the State has a general obligation to take adaptation measures, which must be aimed in particular at strengthening adaptive capacities, increasing resilience to climate change and reducing vulnerability to such change (I.A), and by sectoral and cross-cutting obligations (I.B).

This obligation, they argue, flows not only from domestic constitutional law, but is also clarified and reinforced by international and EU law (including the UNFCCC and the Paris Agreement) and by the law of the Council of Europe, specifically the European Convention on Human Rights. This instrument, they argue, drawing on the ECtHR’s recently climate case-law and its broader environmental jurisprudence and focusing particularly on the right to respect for private and family life (Art. 8 ECHR) and the right to life (Art. 2 ECHR), obliges the State to put in place an appropriate legislative and regulatory framework to effectively protect human life and health against the risks and consequences of climate change. It also requires the State to take preventive measures of a practical nature, in order to protect citizens whose lives may be at risk, and to mitigate the most serious consequences of climate change. And, finally, it requires the State to ensure the effective application of the framework and of the adaptation measures thus put in place, on the basis of the best available science. Reiterating long-standing case-law of the ECtHR, the litigants argue that the French state has an obligation to take all necessary measures to limit exposure to natural risks resulting from climate change, and to ensure that those affected are informed of the existence of such risks.

The action began as a request addressed to the state, which is a procedural requirement under French law before bringing a case to the Council of State (Conseil d’État). If the state responds in an unsatisfactory way or not at all, the case can be then be taken to the Council of State.

African Court on Human and People’s Rights Climate Advisory Opinion

Summary:
On 2 May 2025, a request for an advisory opinion on climate change was submitted to the African Court on Human and People’s Rights. The request was submitted by the Pan African Lawyers Union (PALU), in collaboration with the African Climate Platform, and other African Civil society Organizations including the Environmental Lawyers Collective for Africa, Natural Justice and resilient40, and seeks clarification of States’ obligations in the context of climate change.

Submitted under article 4 of the Protocol to the African Charter on Human and People’s Rights on the establishment of an African Court on Human and People’s Rights and Rule 82(1) of the Rules of the African Court on Human and Peoples Rights, the request submits that “[a]cross the continent, Africans are suffering the consequences of climate change, whether from rising temperatures, unrelenting droughts, catastrophic floods, vanishing biodiversity, or threats to livelihoods. Climate change in Africa has had prior, current and will have future consequences that impact the enjoyment of numerous rights.”

The request sets out impacts, disaggregating them region-by-region and in terms of the groups of people most affected by climate change (mentioning women and girls, children, the elderly, Indigenous peoples, and environmental human rights defenders in particular).

The request then goes on to discuss several issues of law, beginning with issues of admissibility and jurisdiction and then relying on a wide range of rights and instruments, namely:

  • a) the Constitutive Act of the African Union
  • b) the African Charter for Human and Peoples Rights (‘Banjul Charter’), especially articles 2, 3, 4, 5, 8, 9, 10, 11, 12, 14, 16, 17, 18, 19, 20, 21, 22, 23, 24, 60 and 61
  • c) African Union Convention for the Protection and Assistance of Internally Displaced Persons in Africa (Kampala Convention)
  • d) Protocol to the African Charter on Human and Peoples’ Rights on the Rights of Women in Africa (Maputo Protocol)
  • e) The African Charter on the Rights and Welfare of the Child
  • f) The Revised African Convention on Conservation of Nature
  • g) Any other Relevant Instrument.

In doing so, PALU invites the Court to consider international climate change law, including the UNFCCC, the Kyoto Protocol and the Paris Agreement as well as the UN Conventions on Combatting Desertification and on Biological Diversity.

Rights invoked in more detail:
PALU submits that “a rights-based climate approach is needed to address the challenges posed by climate change” and that the human rights framework “provides a robust legal framework upon which the Court may rely to define States’ responsibilities and duties in the context of climate change […] because the Charter clearly provides for collective rights and the explicit protection of the right to a healthy environment.” PALU accordingly invites the Court to consider the following provisions of the Banjul Charter:

  • Articles 2 and 3 (equality and non-discrimination)
  • Article 4 (right to life and inviolability of the human person)
  • Article 5 (right to respect for dignity and prohibition of all forms of exploitation and degradation, including slavery and torture)
  • Article 8 (freedom of conscience and religion)
  • Article 9 (freedom of information and opinion)
  • Article 10 (freedom of association)
  • Article 11 (freedom of assembly)
  • Article 12 (freedom of movement, residence and asylum; prohibition of mass expulsion)
  • Article 14 (right to property)
  • Article 16 (right to health)
  • Article 17 (right to education)
  • Article 18 (protection of the family, prohibition of age and gender discrimination)
  • Article 19 (equality of peoples, prohibition of domination)
  • Article 20 (right of peoples to existence and self-determination)
  • Article 21 (right of peoples to freely dispose of their wealth and natural resources)
  • Article 22 (right of peoples to their economic, social and cultural development)
  • Article 23 (right of peoples to national and international peace and security)
  • Article 24 (right of all peoples to a general satisfactory environment favorable to their development)
  • The request also discusses the implied rights to food and shelter.

Issues for determination:
PALU submits the following issues for determination by the Court (paraphrased):

(a) Whether the Court can be seized with the question of obligations concerning climate change under the Banjul Charter and other relevant instruments?

(b) Whether the Court can interpret and lay down applicable custom and treaty law regarding States’ obligations and duties in the context of climate change?

If these questions are resolved in the affirmative, the Court is invited to further determine:

(a) What, if any, are States’ human and peoples’ rights obligations to protect and safeguard the rights of individuals and peoples of the past (ancestral rights), and present and future generations?

(b) Whether States have positive obligations to protect vulnerable populations including environmental human rights defenders, indigenous communities, women, children, youth, future generations, the current generation, past generations, the elderly and people with disabilities from the impact of climate change in line with the relevant treaties?

(c) What human rights obligations do States have to facilitate a just, transparent, equitable and accountable transition in the context of climate change in Africa?

(d) What are the obligations of African States in implementing adaptation, resilience and mitigation measures in response to climate change?

(e) What, if any, are applicable human rights obligations of States to compensate for loss, damage and reparations?

(f) What responsibilities, if any, do African States have in relation to third parties, including international monopolies, multinational corporations and non-state actors operating on the continent, to ensure that international and regional treaties and laws on climate change are respected, protected, promoted and implemented?

(g) What, if any, is the nature of the obligations on African States to cooperate with other states especially historical emitters to limit global warming to below the 1.5°C threshold, to avert an existential climate crisis for present and future generations on the continent?

Senior Citizens v. Korea

Summary:
In June 2024, a group of 123 older South Korean citizens brought suit against their government before South Korea’s National Human Rights Commission, arguing that the government’s greenhouse gas mitigation plans had violated their human dignity and their right to life. Their case concerns both mitigation and adaptation action. In terms of mitigation, they sought enhancement of the country’s 2030 national greenhouse gas reduction targets and an ambitious next nationally determined contribution (NDC) under the Paris Agreement. In terms of adaptation, they sought a risk assessment of impacts on human rights, including the rights to life, food, health, and housing, and emphasized the State’s fundamental obligation to protect these rights. This assessment should entail, they argued, “a factual survey and epidemiological investigation into the risks the climate crisis poses to the human rights of vulnerable social groups, including older persons”, and lead to more ambitious adaptation measures.

2023 Adaptation Climate activists and human rights defenders Domestic court European Convention on Human Rights Private and family life Right to life Sea-level rise The Netherlands

Greenpeace Netherlands v. State of the Netherlands (Bonaire)

Summary:
On 28 January 2026, the Commerce team of the Hague District Court issued a judgment in a case brought by Greenpeace and seven residents of the Caribbean island of Bonaire against the Dutch government. In examining the case, which concerned both alleged mitigation and adaptation failures, the Court found several violations of the human rights guaranteed in the European Convention on Human Rights (ECHR). In particular, and extensively discussing the European Court of Human Rights’ (ECtHR) KlimaSeniorinnen judgment of 9 April 2024, the Court found that the Dutch State had failed to fulfil its positive obligations towards the inhabitants of Bonaire under Article 8 ECHR, because the authorities’ mitigation and adaptation measures taken as a whole in relation to them did not meet the Netherlands’ obligations under the international climate regime (the UNFCCC and the Paris Agreement, discussing also the Kyoto Protocol). Additionally, given that the Dutch State took mitigation and adaptation measures for the inhabitants of Bonaire much later and less systematically than for the inhabitants of the European Netherlands, it found violations of the ECHR’s non-discrimination norms.

Background to the case:
On 11 May 2023, Greenpeace and seven residents of the Caribbean island of Bonaire sent a pre-litigation letter (Dutch: sommatie) to the office of the Prime Minister of the Netherlands. The letter claimed that the Netherlands does not sufficiently protect the authors from climate change and thereby violates their human rights. Since 2010, Bonaire has been a special municipality of the Netherlands and part of the Caribbean Netherlands. In the pre-litigation letter, the plaintiffs claim that the duties of care arising from Articles 2 and 8 of the European Convention on Human Rights (ECHR), the right to life and the right to family life, have been breached. The inaction of the Netherlands in sufficiently addressing climate change, they argue, violates these human rights. Therefore, they made the following demands:

  1. The Netherlands must implement the necessary measures to protect Bonaire from the consequences of climate change.
  2. The State shall develop and implement a policy which guarantees a 100% reduction of Dutch emission of all greenhouse gases in 2030 when compared to 1990 levels.
  3. Lastly, as part of and to realize the demands above, the State must implement all necessary measures to ensure that, in January 2040 at the latest, the joint volume of the national emission of all greenhouse gases will have been reduced by 100% when compared to 1990 emissions levels.

With the pre-litigation letter to the Prime Minister, the plaintiffs asked for negotiations to find a mutually agreeable decision on their demands. Given the lack of successful negotiations, the plaintiffs initiated proceedings under the Dutch Act on Redress of Mass Damages in Collective Action (WAMCA, alternatively translated as the Settling of Large-scale Losses or Damage (Class Actions) Act), which restructured the Dutch legal system’s approach to mass litigation and collective redress since coming into force in 2020.

Admissibility:
On 25 September 2024, Greenpeace announced that a court in the Hague had ruled that its action on behalf of the public interest of the people of Bonaire was admissible. A hearing was set to follow in 2025.

Judgment of 28 January 2026:
The District Court of Hague (Court) found that individuals residing in Bonaire were owed positive obligations arising from the application of Article 8 of the ECHR in the context of climate-related risks as identified in the judgment in Verein KlimaSeniorinnen et al. v. Switzerland. It further found that the non-discrimination norms found in Article 14 of the ECHR and Article 1 of Protocol 12 to the ECHR were applicable to the case in light of the difference in treatment of the residents of Bonaire arising out of the lack of a climate adaptation applicable to Bonaire, when in contrast, a coherent and integrated climate adaptation policy was being implemented for the European Netherlands since 2016.

In its reasoning, it assessed the Netherlands’ and the EU’s climate mitigation laws as falling short of the minimum requirements of ambition and stringency, which it derived from decisions of the Conference of Parties (COP) to the UNFCCC read with provisions of the UNFCCC and the Paris Agreement. It negatively appraised the Netherlands’ reliance on a ‘grandfathering’ approach, which it found to be ‘controversial’ although not prohibited. These shortcomings informed its negative ‘overall assessment’ of the Netherlands’ climate mitigation framework for compliance with Article 8 of the ECHR, as interpreted by the European Court of Human Rights in the Verein KlimaSeniorinnen judgment. Next, regarding the positive obligation to effectively implement climate mitigation measures, it held that the State’s admission that the 2030 emissions reduction was ‘highly unlikely’ to be met as a decisive factor in determining a breach of that obligation.

Regarding adaptation measures, the Court found that although initial steps have been taken (for instance, the setting up of a local project for the development of an adaptation plan) the fact that no concrete timeline for the implementation of adaptation measures exists despite the known climate risks (especially that of partial submergence significant parts of land territory by 2050), and that the State has carried out insufficient scientific research and committed no financial resources for certain adaptation-related policies in Bonaire were assessed negatively. On this basis the Court concluded that the State had breached its positive obligation to sufficiently and in a timely manner, take appropriate adaptation measures in Bonaire. Finally, it found that the State did not fulfil its obligations to provide relevant environmental information to the residents of Bonaire and allow for their participation in climate-related decision making at least until 2023.

The Court found that the State did not provide an adequate justification of the unequal treatment of Bonaire as it related to its inclusion within the Netherland’s overall climate adaptation policy and the commitment of resources for the implementation of adaptation measures. It thus found that the State had breached its obligation of non-discrimination under Article 14 of the ECHR and Article 1 of Protocol 12 to the ECHR.

Order:
Based on the above, the Court partially allowed the plaintiffs’ claim for specific performance against the state and ordered the State to ensure incorporate ‘absolute’ emissions reduction targets compatible with the minimum requirements arising out of COP decisions and the Paris Agreement into its national climate legislation and provide insight into Netherlands’ ‘remaining emission allowance’; to draft and implement an appropriate national adaptation plan that also includes Bonaire; and pay legal costs to the plaintiffs. It rejected the plaintiffs’ requests that the Court order the State to adopt specific emissions reduction targets, and a binding national carbon budget determined in accordance with its fair share of the global carbon budget for 1.5˚C.

In doing so, it held that the State has considerable policy-making discretion in choosing its measures to comply with its international obligations under the UN climate treaties, meaning that the Court ordered the State to take effective measures to fulfil its UN obligations in a timely manner, without issuing any concrete orders as to the measures to be taken, deferring to the other branches of government and the separation of powers in this regard (trias politica).

Appeal:
With a letter dated 10 April 2026, the Dutch government announced that it had decided to appeal this case. The letter (in Dutch) indicates that the government has identified “compelling (legal) reasons to have the ruling reviewed by the Court of Appeal in The Hague”. The government indicates its reservations about the legal framework applied by the district court and the obligations the court derives from decisions of UN climate conferences (COP decisions). The government also contests the court’s finding that emissions from international aviation and maritime shipping must be taken into account when setting national emission reduction targets; according to the government, this does not align with current international practice, under which these emissions are regulated through specialized UN organizations (ICAO and IMO).

The government also noted that it was seeking a motion to stay the provisionally enforceable nature of the ruling, which would otherwise require the government to immediately implement the judgment, even if an appeal is filed, and include absolute emission reduction targets for the entire economy in national targets, including emissions from international aviation and shipping.

Adaptation Climate-induced displacement Domestic court Indigenous peoples' rights Kenya Loss & damage Non-discrimination Right to life Right to property

Legal Advice Centre T/A Kituo cha Sheria & Anor v. Attorney General and 7 Others (Iten ELC Petition No. 007 of 2022)

Summary:
In 2022, a case was filed in Kenya on behalf of members of indigenous Ilchamus and Tugen communities living on the shores of Lake Baringo. Due to flooding, Lake Baringo has doubled in size since 2010. The plaintiffs assert that, as residents of the area, they are victims of climate change-related flooding, which in turn has caused displacement, deaths and harm to property. The petitioners allege violations of their constitutional human rights as well as violations of the Kenyan government’s duties under the domestic Climate Change Act. Drawing on a 2021 government report that identified climate change as the main cause of flooding in the area, the plaintiffs seek to — in the words of their lead attorney, Omondi Owino, “enforce the climate change duties of public officials”.

The petitioners’ motion for the Supreme Court of Kenya to create a three-judge Environment and Land Court (ELC) panel to hear the case was allowed. A hearing in the case — which alleges that government officials “failed, refused, or neglected” to “anticipate, prevent, or minimize” the impacts of climate change — was held on 24 October 2023 at the ELC in Iten. Government lawyers have reportedly contested the claims and the plaintiffs’ claims for damages, arguing that Kenya’s contribution to global climate change is minimal.

R (Friends of the Earth Ltd, Kevin Jordan and Doug Paulley) v. Secretary of State for Environment, Road & Rural Affairs

Summary:
On 17 October 2023, the reportedly first-ever adaptation case in the United Kingdom was brought against the government before the UK’s High Court of Justice. The plaintiffs in this case included Kevin Jordan, a homeowner from Norfolk (UK), who alleged that his home was acutely threatened by coastal erosion, with the road leading up to it having already collapsed into the sea. Jordan brought his case together with the NGO ‘Friends of the Earth’ and disability rights activist Doug Paulley, a care home resident who alleged that his health conditions were being exacerbated by climate-aggravated heatwaves. Together, the plaintiffs challenged the UK’s National Adaptation Programme (NAP). Domestic law requires the production of new NAP every five years, and the most recent version — NAP3 — was published in July 2023. The claimants argued that NAP3 is deficient for the following reasons:

  1. Failure to set sufficiently specific objectives;
  2. Failure to conduct and publish information on the assessment of the risks involved in implementing NAP3;
  3. Failure to consider the unequal impacts of NAP3 on protected groups (on the grounds of age, race and disability); and
  4. Violation of Articles 2, 8, 14 and Article 1 of Protocol 1 of the European Convention on Human Rights (the rights to life, respect for private and family life, non-discrimination and property, respectively), as enshrined in the Human Rights Act 1998.

In regards to the alleged human rights violations, the plaintiffs invoked:

a. The well-established but urgent need for long-term policy and protected funding to enable care-homes (and similar healthcare settings) to adapt to excessive heat. This remains absent in NAP3 despite the increasing frequency and severity of annual heatwaves.
b. There being no new policy to manage overheating risks in existing health and social care buildings, such that they are properly refurbished as soon as reasonably practicable.
c. A lack of a commitment to provide adequate resources to support communities at imminent risk of being lost to erosion and flooding, including as to the established mental health and emotional wellbeing impacts for those affected.
d. Gaps, inconsistency and uncertainty in the potential allocation of funding provided for a range of areas, in particular for those communities that must (or are likely to have to) relocate and have their homes demolished.
e. There being no insurance or compensation schemes available for the worst affected by coastal erosion and who lose their homes.
f. No evidence of their being an express consideration, or reasoned analysis, of what a fair balance to strike would be between doing more to safeguard the human rights of vulnerable people and the interests of wider society.

High Court Judgment:
In a judgment issued on 25 October 2024, the High Court of Justice for England and Wales rejected the applicants’ claims. Justice Chamberlain, in his judgment, found that there had been no error of law in this case. His ruling extensively considered the 2024 Verein KlimaSeniorinnen judgment of the European Court of Human Rights, but found that “[u]nlike in the field of mitigation, and subject to the arguments about the effect of the ECHR as interpreted in [Verein KlimaSeniorinnen] (…), there is no internationally binding quantified standard governing how States must adapt to climate change. It would be very difficult to devise any such standard because the risks of climate change differ widely from state to state (and indeed within states). In some places, the main risk may be from flooding, in other places extreme heat or drought. Elsewhere, there may be a combination of risks, which all have to be addressed but some of which are more urgent than others. Moreover, the profile of risks, and the priorities attached to addressing them, may change over time” (para. 92 of the High Court ruling).

Assessing the Verein KlimaSeniorinnen judgment overall, Judge Chamberlain found that while this judgment “represents a significant development of the case law in relation to climate change, not only as regards the standing of associations to bring claims before the Strasbourg Court, but also as regards the scope and extent of the positive obligations of the State and the margin of appreciation to be accorded when assessing whether those obligations have been discharged”, “the significance of the judgment for the UK’s climate change framework should not be overstated.” The Judge noted that KlimaSeniorinnen focused heavily on lacunae in domestic legislation and the targets set out in the Paris Agreement, whereas the law of the United Kingdom does not feature similar lacunae in mitigation target-setting.

Lawyers for the government in this case had sought to dismiss the findings of the ECtHR, as made in para. 552 of KlimaSeniorinnen, as an obiter dictum. This paragraph of the Strasbourg Court’s judgment reads as follows:

Furthermore, effective protection of the rights of individuals from serious adverse effects on their life, health, well-being and quality of life requires that the above-noted mitigation measures be supplemented by adaptation measures aimed at alleviating the most severe or imminent consequences of climate change, taking into account any relevant particular needs for protection. Such adaptation measures must be put in place and effectively applied in accordance with the best available evidence (…) and consistent with the general structure of the State’s positive obligations in this context (…).

Judge Chamberlain disagreed with the government as concerns the nature of this finding, noting the dangers of applying “common law concepts [the idea of obiter dicta] to the judgment of a court most of whose members come from different legal traditions.” Still, Judge Chamberlain noted that the Strasbourg Court’s findings were of a general nature (para. 101). He found that KlimaSeniorinnen “appears to indicate that the positive obligation imposed by Articles 2 and 8 [ECHR] extends to adopting and effectively implementing ‘adaptation measures aimed at alleviating the most severe or imminent consequences of climate change, taking into account any relevant particular needs for protection'”, stemming from the State’s underlying regulatory obligation. He notes that “[w]hat that means in the context of adaptation measures, however, is far from clear” (para. 103), given that adaptation measures were not central to the KlimaSeniorinnen case, and that the international legal framework in this regard is less well-developed than for mitigation measures. He went on to anticipate future rulings from the ECtHR, considering it

(…) likely that, if the Strasbourg Court had in a future case to apply the reasoning in [Verein KlimaSeniorinnen] to the adaptation context, it would say that:
(a) the narrow margin of appreciation in relation to the mitigation aims was justified by reference to the internationally agreed objective of carbon neutrality by 2050 and the impact of one State’s default on other States;
(b) neither of these features applies in the field of adaptation; and
(c) accordingly, in the field of adaptation, States are to be accorded a wide margin of appreciation in setting the relevant objectives and a wider margin still in setting out the proposals and policies for meeting them (by analogy with the margin accorded to the State in setting the means for achieving the mitigation objectives).

Accordingly, he found that the current adaptation framework in the United Kingdom appears to “fall comfortably within the UK’s margin of appreciation under Articles 2 and 8 ECHR” and is not “contrary to any clear and consistent line of authority from the Strasbourg Court”. On this basis, he found that there was neither an error of law nor an incompatibility with human rights law evident in this case.

Tsama William & 47 Ors v. Uganda

Summary:

The case was initiated following multiple landslides that occurred in December 2019 in the Bududa district in Eastern Uganda, in an area that is prone to landslides, which the applicants allege were exacerbated by climate change. The applicants claim that the landslides resulted in their displacement from their homes, killed their relatives and destroyed their property and the environment.

The applicants brought the case against the Ugandan government, the environmental authority and the local government of Bududa before the High Court of Uganda seeking orders for protective measures and compensation.  

Claims:

The applicants claim that the respondents have violated their positive obligations under statutory law to protect the applicants from recurrent landslides. They argue that the respondents’ failures to put in place an effective machinery for dealing with landslides and promptly warn the applicants about known risks, violated their fundamental rights to life, a clean and healthy environment, property, and physical and mental health. Aside from declaratory relief, the applicants claim a sum of 6.8 billion Ugandan Shillings as compensation for loss of life, destruction of property, physical and mental harm, as well as the cost of resettlement to safer areas.  The applicants further allege that the risk of future landslides owing to extreme weather events caused by climate change requires the respondents to take measures to relocate and resettle the applicants.  

This case is about adaptation to environmental risks (i.e. it is broader than climate adaptation), since the applicants principally rely on evidence that the problem of recurring landslides in the Bududa district has been going on since the beginning of the 20th century. However, the applicants rely on climate change as one among the factors contributing to the landslide risks they had previously faced and are likely to face in the future, as well as their vulnerability.

Status of the case: The case is pending before the High Court of Uganda.

Climate Advisory Opinion of the IACtHR (OC 32/2025)

Summary:
On 3 July 2025, the Inter-American Court of Human Rights (IACtHR) issued its long-awaited advisory opinion on climate change, at the request of the governments of Chile and Colombia.

Advisory opinion request:
On 9 January 2023, Colombia and Chile jointly filed a request for an advisory opinion on the climate emergency and human rights to the IACtHR. The two governments requested clarification of the scope of States’ obligations, both in their individual and collective dimensions, in responding to the climate emergency within the framework of international human rights law, taking into account the different effects that climate change has on people in different regions and on different population groups, nature and human survival. The governments asked the Court to answer a series of questions grouped into six thematic areas, namely on:

A. The scope of States’ obligations to protect and prevent, including regarding their obligations to mitigate, adapt, regulate and monitor, and their response to loss and damage;

B. States’ obligations to protect the right to life given the existing climate science, and taking into account the right of access to information and transparency of information, including under the Escazú Agreement;

C. States’ obligations with respect to the rights of children and new generations, given especially the vulnerability of children;

D. On the State’s obligations concerning consultative and judicial procedures, taking into account the limited remaining carbon budget;

E. The protective and preventative obligations concerning environmental and land rights defenders, as well as women, indigenous peoples and Afro-descendant communities; and

F. Shared and differentiated obligations and responsibilities in terms of the rights of States, the obligation of cooperation and given the impacts on human mobility (migration and forced displacement of people).

Extended summary of the request:
In their request to the IACtHR, the two governments submitted that they are already dealing with the consequences of the climate emergency, including the proliferation of droughts, floods, landslides and fires. These, they submitted, underscore the need for a response based on the principles of equity, justice, cooperation and sustainability, as well as human rights. The two governments noted that climate change is already putting humans and future generations at risk, but that its effects are not being experienced uniformly across the international community. Instead, given their geography, climatic conditions, socioeconomic conditions and infrastructure, they are particularly being felt in the most vulnerable communities, including several countries in the Americas. They emphasized that these effects are not proportionate to these countries’ and communities’ contribution to climate change.

The governments, in their request, emphasized the relevance of the right to a healthy environment, as well as other interrelated substantive and procedural rights (affecting life, human survival and future generations). They reviewed the existing scientific evidence concerning the impacts and progression of climate change from the IPCC, and noted the vulnerability of the Andean region. The two governments referred to the 2017 Advisory Opinion of the IACtHR, which recognized the right to a healthy environment as an autonomous and individual right, and referred to the negative effects of climate change. However, they argued, there is a need to further clarify the human rights impacts of climate change, and corresponding obligations. In this regard, they raised the existence also of collective rights for the protection of nature under international human rights and environmental law, and cited the need to protect fundamental biomes like the Amazon and to understand States’ shared but differentiated responsibilities in a way that copes with loss and damage. The two governments invited the Court to set out clear standards against the background of litigation and related developments.

Consultation procedure:
In accordance with the Rules of Procedure of the IACtHR (Art. 73(3)), all interested parties (individuals and organizations) are invited to present a written opinion on the issues covered in the advisory opinion request. The President of the Court has established 18 August 2023 as the deadline for doing so. More information is available here.

Advisory opinion of 3 July 2025:
On 3 July 2025, following an oral hearing, the IACtHR issued its advisory opinion in these proceedings (in Spanish, with the text in English to follow). In a 234-page opinion, the Court addressed the questions raised by the governments of Chile and Colombia in their request.

The advisory opinion covers a wide range of relevant issues and obligations, and provides in-depth clarifications of the legal issues raised. It covers, in short:

  • The procedure, competence of the Court and admissibility of the request, as well as a number of other preliminary considerations, including about the (scientific and other) sources used by the Court and the scope of the opinion.
  • The facts of the climate emergency, including its causes, differential contributions of different actors, and its impacts on natural systems, humans, vulnerable territories and ecosystems, as well as the need for urgent action, the possibilities and need for mitigation, the need for adaptation, and the seriousness of climate impacts.
  • The complexity of required responses, including discussions of resilience and sustainable development as a vehicle for protection of both human rights and the environment.
  • The international legal framework around climate change, applicable norms and frameworks, including international investment law, human rights, international environmental law and climate change treaties. The Court also reviewed the case-law of other adjudicators in the context of climate change.
  • The obligations of States in the context of the climate emergency, including the scope of human rights obligations to respect rights, protect rights (including a reinforced due diligence obligation), and the obligation to take measures to ensure progressive realization of economic, social and cultural rights. This includes discussion of various substantive rights, including particularly the right to a healthy environment but also the rights to life, physical integrity, health, private and family life, property and home, freedom of movement and residence, water and food, work and social security, culture and education. The advisory opinion also includes consideration of procedural rights and the link between these rights and democracy, the right to science and recognition of local knowledge, the right of access to information (and combatting disinformation), the right to political participation and access to justice as well as protection of environmental defenders and equality and non-discrimination norms. In this latter regard, the opinion considers the differential protection owed to children and youth, to Indigenous and tribal peoples, Afrodescendant communities, peasants and those involved in fisheries. It also considers the differential effect of climate change and the implications for fight against poverty.

Opinion of the Court:
Appended to the Court’s extensive consideration of the relevant issues and obligations is its concrete opinion, which reads as follows (translation from the original Spanish, to be replaced with the English-language translation by the Court once available):

THE COURT DECIDES
Unanimously, that:

It is competent to issue the present Advisory Opinion, in the terms of paragraphs 14 to 23.

AND IS OF THE OPINION
Unanimously, that:

  1. According to the best available science, the current situation constitutes a climate emergency due to the accelerated increase in global temperature, produced by diverse activities of anthropogenic origin, undertaken unequally by the States of the international community, which incrementally affect and seriously threaten humanity and, especially, the most vulnerable people. This climate emergency can only be adequately addressed through urgent and effective actions for mitigation, adaptation and progress towards sustainable development, articulated with a human rights perspective, and under the prism of resilience, in the terms of paragraphs 183 and 205 to 216.

    Unanimously, that:
  2. By virtue of the general obligation to respect rights, States have the obligations indicated in paragraphs 219 to 223.

    Unanimously, that:
  3. Under the general obligation to ensure rights, States have an obligation to act in accordance with a standard of enhanced due diligence to counteract the human causes of climate change and protect people under their jurisdiction from climate impacts, in particular those who are most vulnerable, in the terms of paragraphs 225 to 237.

    By six votes in favor and one against, that:
  4. By virtue of the general obligation to ensure the progressive development of economic, social, cultural and environmental rights, States must allocate the maximum available resources to protect persons and groups who, because they are in situations of vulnerability, are exposed to the most severe impacts of climate change, in the terms of paragraphs 238 to 243.
    Judge Patricia Pérez Goldberg dissents.

    Unanimously, that:
  5. By virtue of the general obligation to adopt domestic law provisions, States must integrate into their domestic legal framework the necessary regulations to ensure the respect, guarantee and progressive development of human rights in the context of the climate emergency, in the terms of paragraphs 244 to 246.

    Unanimously, that:
  6. By virtue of the obligation to cooperate, the States are obliged to cooperate in good faith to advance in the respect, guarantee and progressive development of human rights threatened or affected by the climate emergency, in the terms of paragraphs 247 to 265.

    By four votes in favor and three against, that:
  7. The recognition of Nature and its components as subjects of rights constitutes a normative development that makes it possible to reinforce the protection of the integrity and functionality of ecosystems in the long term, providing effective legal tools in the face of the triple planetary crisis and facilitating the prevention of existential damage before it becomes irreversible. This conception represents a contemporary manifestation of the principle of interdependence between human rights and the environment, and reflects a growing trend at the international level aimed at strengthening the protection of ecological systems against present and future threats, in accordance with paragraphs 279 to 286.
    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting.

    By four votes in favor and three against, that:
  8. By virtue of the principle of effectiveness, the imperative prohibition of anthropogenic conducts that may irreversibly affect the interdependence and vital balance of the common ecosystem that makes the life of the species possible constitutes a norm of jus cogens, in accordance with paragraphs 287 to 294.
    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting.

    By a vote of five in favor and two partially against, that:
  9. The right to a healthy climate, understood as a component of the right to a healthy environment, protects in its collective dimension the present and future humanity, as well as Nature, in the terms of paragraphs 298 to 316.
    Judge Nancy Hernández López and Judge Patricia Pérez Goldberg dissenting in part.

    By six votes in favor and one partially against, that:
  10. By virtue of the right to a healthy climate, States must protect the global climate system and prevent human rights violations derived from its alteration. Therefore, they must mitigate GHG emissions, which implies (i) adopting regulations on the matter that define a mitigation goal and a mitigation strategy based on human rights, as well as regulating the behavior of companies, in the terms of paragraphs 323 to 351; (ii) adopting mitigation supervision and control measures, in the terms of paragraphs 352 to 357, and (iii) determining the climate impact of projects and activities when appropriate, in the terms of paragraphs 358 to 363.
    Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  11. By virtue of the right to a healthy environment, States must (i) protect nature and its components from the impacts of climate change, and (ii) establish a strategy to move towards sustainable development, in the terms of paragraphs 364 to 376.

    By six votes in favor and one partially against, that:
  12. By virtue of the rights to life, personal integrity, health, private and family life, property and housing, freedom of residence and movement, water and food, work and social security, culture and education, as well as all other substantive rights threatened by climate impacts, States have an enforceability obligation, States have an immediately enforceable obligation to define and update, as ambitiously as possible, their national adaptation goal and plan, in the terms of paragraphs 384 to 391, as well as the duty to act with enhanced due diligence in compliance with the specific duties set forth in paragraphs 400 to 457.
    Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  13. By virtue of the democratic principle, the States must strengthen the democratic rule of law as an essential framework for the protection of human rights, the effectiveness of public action, and open and inclusive citizen participation, also ensuring the full exercise of procedural rights, in the terms of paragraphs 460 to 469.

    By six votes in favor and one partially against, that:
  14. By virtue of the human right to science and the recognition of local, traditional and indigenous knowledge, protected by Articles 26 of the Convention and 14.2 of the Protocol of San Salvador, all persons have the right to access the benefits of measures based on the best available science and on the recognition of local, traditional or indigenous knowledge, in the terms of paragraphs 471 to 487.
    Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  15. Under the right of access to information, States have obligations regarding (i) production of climate information, in the terms of paragraphs 501 to 518; (ii) disclosure of information relevant to the protection of human rights in the face of climate change, in the terms of paragraphs 519 to 523, and (iii) to adopt measures against disinformation, in the terms of paragraphs 524 to 527.

    Unanimously, that:
  16.

    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  18. By virtue of the right to defend human rights, States have a special duty to protect environmental defenders that translates into specific obligations, among others, to protect them, investigate and, if necessary, punish attacks, threats or intimidations they suffer, and to counteract the “criminalization” of the defense of the environment, in the terms of paragraphs 566 to 567, and 575 to 587.

    Unanimously, that:
  19. States should adopt measures aimed at addressing the way in which the climate emergency exacerbates inequality and has a differentiated impact on people living in multidimensional poverty, in the terms of paragraphs 626 and 627.

    By four votes in favor and three partially against, that:
  20. States have specific obligations in situations of special vulnerability such as those faced by (i) children, and (ii) indigenous peoples, tribes, Afro-descendants, and peasant and fishing communities, (iii) people who suffer differentiated impacts in the context of climate disasters, in the terms of paragraphs 599 to 602, and 604; 606 to 613, and 614 to 618. Likewise, States must adopt measures to protect persons who do not belong to the traditionally protected categories but who are in a situation of vulnerability for dynamic or contextual reasons, in the terms of paragraphs 628 and 629.
    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg partially dissent.
