Plan B. Earth and Others v. the United Kingdom

Summary:

On 11 July 2022, an application against the United Kingdom was filed before the European Court of Human Rights by the NGO Plan B. Earth and four individual applicants. The applicants argued that the United Kingdom’s government violated their rights under Articles 2, 8 and 14 of the ECHR by failing to take practical and effective measures to tackle the threat of anthropogenic climate change. They also submitted that they had suffered violations of their procedural rights under Articles 6 and 13 ECHR because they had been denied a full hearing of their case.

Citing the UK Government’s acknowledgment of the fact that climate change is a serious threat to humanity, the applicant NGO submitted that its membership included those “who are exposed to disproportionate and discriminatory impacts and risks, whether by virtue of age, gender, mental health or membership of racially marginalised communities, or because their family life is inextricably linked to communities on the frontline of the crisis.” The applicants also cited the State’s positive obligation to safeguard the right to life, and argued that the Paris Agreement, and its temperature goal of 1,5 degrees Celsius, are relevant in determining the scope of these positive obligations. They argued that practical and effective measures are required to ensure climate mitigation, adaptation, finance flows and loss and damage, and that the respondent State has failed in all four regards.

Victim status:

As concerns the applicants’ victim status, they argued that they were “victims” of the alleged Convention violations. They referred to domestic rules that increase the cost risk by £5,000 for each additional claimant in environmental cases; this rule serves to deter class actions, and therefore prevents applicants from sharing the cost and other risks involved in litigation. They noted that the first applicants’ members include individuals exposed to disproportionate and discriminatory impacts and risks as concerns their age, gender, membership of racially marginalised communities, family life inextricably linked with communities in the Global South, and mental health, and those who are at the intersection of such increased risks. They also noted that, given the high risk of overwhelming and irreversible interference with the applicants’ rights, denying them victim status would render their Convention rights theoretical and illusory.

Status of case:

The ECtHR declared the application inadmissible, holding that the applicants were not sufficiently affected by the alleged breach of the Convention or its Protocols to claim to be victims of a violation within the meaning of Art. 34 of the Convention. This decision was taken by a Committee judicial formation, as the result of a written procedure without a public decision.

According to Plan B Earth’s press release following the decision, the panel was composed of three judges, among which the UK Judge Tim Eicke.

Response of litigants:

In response to the judgment, the litigants expressed disappointment over the ECtHR’s disengagement with their claims and the colonial, racial and class-based inequalities at the heart of the case, with Marina Xochitl Tricks arguing for example that “[t]he white working class, diaspora communities in the UK, and colonised communities globally know that the reality we live is one of injustice. (…) [I]t is time for us to stop pretending that justice will come from the colonial classist courts and start building up our own Peoples’ Tribunals. Our people back home are being killed, dispossessed and disappeared everyday at the hands of global capital, that sows violence and disorder in our communities. We know that those networks extend into the banks and establishment here in the City of London.”

Date of decision:

13 December 2022 (according to the ECtHR’s press release).

Humane Being v. the United Kingdom

Summary:
On 26 July 2022, the NGO Humane Being submitted an application to the European Court of Human Rights arguing that the United Kingdom’s government hat violated the European Convention on Human Rights by failing to protect against the life-threatening risks posted by factory farms. The application invokes Articles 2, 3 and 8 ECHR. Factory farming, the applicants argue, is responsible for the risk of millions of human deaths due to the climate crisis, future pandemics and antibiotic resistance. The case also challenges the effects of agricultural methane emissions and deforestation, and argues that factory farming at current levels is not compatible with the Government’s emissions reduction commitments.

Status of case:
The ECtHR declared the application inadmissible in a single judge judicial formation in a non-public written procedure. The (anonymous) judge decided that the applicant was not sufficiently affected by the alleged breach of the Convention or its Protocols to claim to be a victim of a violation within the meaning of Article 34 ECHR. Single judge decisions are not published to the Court’s HUDOC database.

Daniel Billy et al. v. Australia (Torres Straits Islanders case)

Summary:
This petition against Australia was brought to the UN Human Rights Committee by a group of eight indigenous Torres Straits Islanders in 2019, in their own names and on behalf of their children. In their petition, they argued that the Australian government had violated their rights, as inhabitants of low-lying islands, under the International Covenant on Civil and Political Rights (ICCPR) because of its inaction in addressing climate change (failure to mitigate emissions and to take adaptation measures).

Rights at stake:
The applicants in this case invoked a series of rights in the ICCPR, on behalf of themselves and their children, contesting the respondent State’s failure to adopt mitigation measures to reduce greenhouse gas emissions and cease the promotion of fossil fuels. To support this, they drew on Article 27 (the right to culture), Article 17 (the right to be free from arbitrary interference with privacy, family and home), and Article 6 (the right to life) ICCPR. They argued that the indigenous peoples of the Torres Strait Islands, especially those who reside on low-lying islands, are among the most vulnerable to the impacts of climate change. They considered that the Australian government must ensure both mitigation and adaptation measures in order to adequately protect their rights. Previously, the Torres Strait Regional Authority (TSRA), a government body, had stated that “the effects of climate change threaten the islands themselves as well as marine and coastal ecosystems and resources, and therefore the life, livelihoods and unique culture of Torres Strait Islanders.”

Outcome:

On 21 July 2022, the Human Rights Committee adopted its Views in this case.

Observations of the State:

The Australian Government argued that the case was inadmissible, contesting the relevance of climate-related international agreements and its own ability to be held (legally or practically) responsible for climate-related harms. It also submitted that it was not possible to attribute climate change to the State party under international human rights law.

The HRC’s considerations on the admissibility:

On the issue of the exhaustion of domestic remedies, the Government’s position was that it did not owe a duty of care for failing to regulate environmental harm, and that it was not required to provide a remedy where (including in the present case) it understood there to be no breach of ICCPR rights. This question was accordingly reserved to the examination of the merits.

Concerning mitigation measures, the HRC noted that Australia is and has been a major greenhouse gas emitter, and ranks high on economic and development indices. As a result, it found that the alleged (in)actions fell under its jurisdiction under articles 1 or 2 of the Optional Protocol.

Concerning the imminence of the risk concerned, and accordingly the issue of victim status / standing, the Committee found that the authors of this Communication, “as members of peoples who are the longstanding inhabitants of traditional lands consisting of small, low-lying islands that presumably offer scant opportunities for safe internal relocation – are highly exposed to adverse climate change impacts”. Given the uncontested dependence of their lives and cultures on natural resources and phenomena, and their inability to finance adaptation measures on their own, the authors were considered to be “extremely vulnerable to intensely experiencing severely disruptive climate change impacts”. Given the authors’ allegations of serious ongoing adverse impacts, the HRC declared their claims under articles 6, 17, 24 (1) and 27 of the ICCPR admissible.

Merits:

Article 6

The Committee recalled that the right to life cannot be interpreted restrictively, and that it requires States to adopt protective measures (i.e. that it entails positive obligations). It recalled its own General Comment No. 36, issued in 2018, in establishing that the right to life also extends to reasonably foreseeable threats to life, including adverse climate change impacts and environmental degradation.

The Committee rejected Australia’s allegation that the interpretation of the ICCPR contained in this General Comment was not compatible with the rules of treaty interpretation under general international law. It then went on to recall its own earlier Teitiota v. New Zealand case (on climate-induced displacement), ultimately finding that the authors were not currently facing health impacts or real and reasonably foreseeable risks of being exposed harms to their right to life. The Committee also noted that the right-to-life claim being made largely related to the authors’ ability to maintain their culture, which falls under article 27 ICCPR.

Regarding the authors’ submission that, absent urgent action, their islands will become uninhabitable within 10 to 15 years, the Committee noted the adaptation and mitigation measures currently planned or being taken, and found that the time frame of 10 to 15 years could allow for additional protective measures or relocation programmes. As a result, it found that there had been no violation of the right to life in this case.

Article 17

The authors claimed that climate change already affects their private, family and home life, given that they may be forced to abandon their homes. The Committee considered that the authors’ dependence on marine and terrestrial resources and ecosystems is a component of their traditional indigenous way of life, falling under the scope of Article 17 ICCPR.

Considering the adaptation measures and related plans in place, the Committee noted the existence of unexplained delays in seawall construction and the lack of explanation concerning the loss of marine resources, crops and fruit trees. It noted the ongoing inundation of villages and ancestral burial lands; the withering of traditional gardens through salinification; the decline of nutritionally and culturally important marine species; coral bleaching and ocean acidification; and the authors’ anxiety and distress. The Committee also noted the importance of community lands for the authors’ most important cultural ceremonies. It accordingly found that:

“that when climate change impacts – including environmental degradation on traditional [indigenous] lands (…) – have direct repercussions on the right to one’s home, and the adverse consequences of those impacts are serious because of their intensity or duration and the physical or mental harm that they cause, then the degradation of the environment may adversely affect the well-being of individuals and constitute foreseeable and serious violations of private and family life and the home.”

Finding that Australia had failed to discharge its positive obligation to implement adequate adaptation measures to protect the authors’ home, private life and family, the HRC found a violation of the authors’ rights under article 17 ICCPR.

Article 27

Article 27 ICCPR recognizes the right of members of minority indigenous groups to the enjoyment of culture, and protects the survival and continued development of their cultural identity. Interpreted in the light of the UN Declaration on the Rights of Indigenous Peoples, this right enshrines the inalienable right of indigenous peoples to enjoy their traditional territories and natural resources. Here, the authors argued that their ability to maintain their culture has already been impaired due to climate change impacts, which have eroded their traditional lands and natural resources, for which there is no substitute on mainland Australia. The Committee found that these climate impacts represent a threat that was reasonably foreseeable by the State party, as the authors’ community had been raising the issue since the 1990s. While noting existing seawall construction projects, it considered that the delay in initiating these projects indicated an inadequate response by the State party to the threat in question. It found that the failure to adopt timely and adequate adaptation measures “to protect the authors’ collective ability to maintain their traditional way of life, to transmit to their children and future generations their culture and traditions and use of land and sea resources discloses a violation of the State party’s positive obligation to protect the authors’ right to enjoy their minority culture.” Accordingly, it found a violation of Article 27 ICCPR.

As a result of its findings concerning Articles 17 and 27 ICCPR, the HRC considered it not necessary to examine the authors’ remaining claims under article 24 (1) ICCPR.

Remedies:

Under Article 2 (3) (a) ICCPR, the HRC noted that the State was required to make full reparation to the authors, which meant providing adequate compensation; engaging in meaningful consultations with their communities to conduct needs assessments; continuing its adaptation measures and monitoring and reviewing the effectiveness of existing measures; and taking steps to prevent similar violations in the future. The Committee requested the State to provide it with information about the measures taken in this regard within 180 days.

Separate opinions:

Several HRC members appended individual opinions to the Views. These include:

  • The individual opinion by Committee Member Duncan Laki Muhumuza, arguing that there had been a violation of Article 6 ICCPR (the right to life);
  • The individual opinion by Committee Member Gentian Zyberi, concurring but arguing that the Committee had focused too heavily on adaptation measures, and should instead have more clearly linked the right under Article 27 ICCPR to mitigation measures;
  • The joint opinion by Committee Members Arif Bulkan, Marcia V. J. Kran and Vasilka Sancin (partially dissenting), who argued that there had been a violation of Article 6 ICCPR (the right to life). They argued in particular that the “real and foreseeable risk” standard employed by the majority interpreted Article 6 too restrictively, and was inappropriate here as it had been borrowed from the dissimilar context of its refugee cases (Teitiota v. New Zealand, the HRC’s first climate-induced displacement case).

Aji P. and Others v. the State of Washington

Summary:
This case was brought by 13 young people aged between 8 and 18 who sued the US State of Washington, its Governor, and various other state agencies, arguing that the state had “injured and continue[d] to injure them by creating, operating, and maintaining a fossil fuel-based energy and transportation system that [the State] knew would result in greenhouse gas (“GHG”) emissions, dangerous climate change, and resulting widespread harm.” In doing so, they invoked their “fundamental and inalienable constitutional rights to life, liberty, property, equal protection, and a healthful and pleasant environment, which includes a stable climate system that sustains human life and liberty.” They also invoked the impacts on indigenous peoples’ rights. The plaintiffs requested the judiciary to “[o]rder [the state] to develop and submit to the Court . . . an enforceable state climate recovery plan”.

A number of amici filed briefs in the case. For example, the Swinomish Indian Tribal Community, Quinault Indian Nation, and Suquamish Tribe argued that local tribes were already seeing impacts on their traditional lands and abutting marine waters. The Environmental Law Alliance Worldwide (ELAW-US) noted the well-documented impacts of climate change on human and constitutional rights. The League of Women Voters of Washington argued that access to judicial action was particularly important for minors who did not enjoy access to the right to vote. And a group of environmental NGOs submitted that “the right to a healthful and pleasant environment underlies our continued ability to claim our explicitly-guaranteed rights to life and liberty.”

On 8 February 2021, the Court of Appeals of the State of Washington held that it “firmly believe[d] that the right to a stable environment should be fundamental.” It also recognized “the extreme harm that greenhouse gas emissions inflict on the environment and its future stability.” However, it held that “it would be a violation of the separation of powers doctrine for the court to resolve the Youths’ claims.” It accordingly dismissed the claim.

On 6 October 2021, the Supreme Court of the State of Washington denied the petition for review in this case. González, C.J. (dissenting) noted that the plaintiffs “asked this court to recognize a fundamental right to a healthful and pleasant environment that may be inconsistent with our State’s maintenance of a fossil-fuel-based energy and transportation system that it knows will result in greenhouse gas emissions. These greenhouse gases hasten a rise in the earth’s temperature. This temperature change foreshadows the potential collapse of our environment. In its place is an unstable climate system, conceivably unable to sustain human life and continued enjoyment of ordered liberty under law. Today, we have an opportunity to consider whether these are the sorts of harms that are remediable under Washington’s law and constitution. We should have granted review to decide that question”.

ICJ Advisory Opinion on Climate Change

Summary:
On 29 March 2023, the United Nations General Assembly (UNGA) adopted a resolution requesting an advisory opinion from the International Court of Justice (ICJ) to clarify States’ international obligations concerning climate change. This resolution, Res. A/77/L.58, was prepared on the initiative of the Government of Vanuatu, and was adopted by consensus by the UNGA. This request led to the largest (in terms of participants) proceedings before the ICJ to date, with 97 States and 11 international organisations making written or oral submissions. On 23 July 2025, the ICJ issued its advisory opinion, which was immediately received as a historic and landmark contribution to clarifying the international obligations of States regarding climate change.

Background:
In September 2021, during the UN General Assembly’s annual meeting, the Prime Minister of the Republic of Vanuatu, Hon. Bob Loughman Weibur, announced that the country would build a coalition of States to seek an advisory opinion on climate change from the International Court of Justice (ICJ). The initiative received support from a large number of co-sponsoring states.

The proposal aims to contest “environmental devastation and large-scale violations of human rights for the most vulnerable”. Under the slogan of “bringing the world’s biggest problem to the world’s highest court”, this initative was originally spearheaded by a group of students from the University of the South Pacific. By July 2022, the alliance behind the initative included over 1500 civil society organisations in 130 countries. It also received the endorsement of the Organisation of African, Caribbean, and Pacific States (OACPS).

In July 2022, Vanuatu’s Minister of Climate Change, Hon. Silas Bule Melve, clarified the country’s ambitions for the advisory opinion. He stated that “[t]his is not a court case, and we do not seek to assign blame. But we do seek a credible way to bolster climate ambition moving forward to save the Paris Agreement and our blue planet”. The Republic’s legal team in this endeavor is led by Julian Aguon and Margaretha Wewerinke-Singh of the Pacific law firm Blue Ocean Law.

This approach follows an earlier initiative from 2012, by Palau and the Republic of the Marshall Islands, which did not manage to rally a majority of General Assembly members in suport of presenting a question concerning climate change to the ICJ.

Question put to the ICJ:
The resolution was adopted by the UN General Assembly on 29 March 2023. It decided, in accordance with Article 96 UN Charter, to request the ICJ, pursuant to Article 65 of its Statute, to render an advisory opinion on the following question:

“Having particular regard to the Charter of the United Nations, the International Covenant on Civil and Political Rights, the International Covenant on Economic, Social and Cultural Rights, the United Nations Framework Convention on Climate Change, the Paris Agreement, the United Nations Convention on the Law of the Sea, the duty of due diligence, the rights recognized in the Universal Declaration of Human Rights, the principle of prevention of significant harm to the environment and the duty to protect and preserve the marine environment,

(a) What are the obligations of States under international law to ensure the protection of the climate system and other parts of the environment from anthropogenic emissions of greenhouse gases for States and for present and future generations;

(b) What are the legal consequences under these obligations for States where they, by their acts and omissions, have caused significant harm to the climate system and other parts of the environment, with respect to:

(i) States, including, in particular, small island developing States, which due to their geographical circumstances and level of development, are injured or specially affected by or are particularly vulnerable to the adverse effects of climate change?

(ii) Peoples and individuals of the present and future generations affected by the adverse effects of climate change?”

Interim developments:
On 25 April 2023, the President of the ICJ made an Order organizing the proceedings and fixing time limits for written submissions by States and international organisations in this case.

In June 2023, the Court authorized the European Union, the Commission of Small Island States on Climate Change and International Law and the International Union for Conservation of Nature to participate in the proceedings.

On 26 November 2024, preceding its oral hearings in these proceedings, the Court held an expert hearing with a group of past and present authors of the reports of the Intergovernmental Panel on Climate Change (IPCC), aiming “to enhance the Court’s understanding of the key scientific findings which the IPCC has delivered through its periodic assessment reports covering the scientific basis, impacts and future risks of climate change, and options for adaptation and mitigation.”

Oral hearings:
From December 2-13 2024, the ICJ held oral hearings in these proceedings. The proceedings included involvement from 97 states and 11 international organizations, making them the ICJ’s most extensive to date, and for some States marking their first-ever involvement with the Court.

The written comments received by the Court (91 written statements as well as and 62 comments on those same statements) were made available online during the course of the proceedings alongside verbatim reports of the oral interventions made and a video livestream.

The written and oral proceedings covered a wide range of topics, from the meaning of CBDR-RC and equity, to the recognition of the human right to a healthy environment, to the interplay between international climate law and other areas of international law (e.g. its relationship with human rights frameworks), with some States arguing that the former represented a lex specialis to the latter that precluded further-reaching obligations under human rights law.

Several judges also asked questions during the oral proceedings, to which the participants were given leave to reply.

Advisory opinion of 23 July 2025:

In its advisory opinion, which can be read in full below, the ICJ was concerned with identifying the most directly relevant applicable law concerning the international obligations of States in the context of climate change. As this was not a contentious case, it did not apply the law to the context of a specific State.

The opinion covered a broad range of aspects: from asserting the role of climate science for the law, to confirming non-refoulement obligations and the ITLOS findings on greenhouse gas emissions as marine pollution, to holding that sea-level rise does not deprive countries of marine or land territory or their statehood. The below sets out core aspects of the opinion in a non-exhaustive way.

First, importantly, the Court did not accept the lex specialis argument made by some states to try to insulate climate change from all obligations except for those enshrined in the climate treaties (and particularly the Paris Agreement). The Court found that the relevant international instruments complement each other, and that it could not find any actual inconsistencies between the climate treaties and other relevant rules of international law. This meant that the Court considered various areas of law applicable, and found that States have obligations under the climate treaties but also under customary law, environmental treaties, and human rights law. In doing so, the Court held that the international law enshrines binding obligations also for states that terminate their membership in the Paris Agreement.

The ICJ’s opinion extensively examines the obligations contained in the international climate law framework. In doing so, it considered the temperature target that States must try to stay below. The Court interpreted the Paris Agreement based on COP decisions (which, it held, represent “subsequent agreements” under the VCLT) and in doing so recognized the 1,5 degree warming threshold as States’ primary goal, over the 2 degree warming threshold also enshrined in Article 2 of the Paris Agreement. Moving to mitigation, the Court held that that Paris Agreement requires States to set out a nationally determined contribution (NDC) based on stringent standard of due diligence. Rejecting the argument that these could not be subjected to any substantive review, it held that NDCs must satisfy certain standards under the Paris Agreement and that the NDCs of all States must, when taken together as a group, be capable of realizing the objectives of the Agreement as set out in article 2 (the 1,5 degree temperature goal).

The Court also examined the adaptation obligations under the Paris Agreement. It held that States have legally binding obligations to take adaptation planning actions. The fulfilment of these adaptation obligations is to be assessed against a standard of due diligence. That means that it is incumbent on States parties to the Paris Agreement to take measures that can enhance adaptive capacity and reduce vulnerability to climate-related impacts.

Turning to obligations under customary international law, including the prohibition of significant transboundary environmental harm (the ‘no harm’ rule), the Court held that this obligation applied to the context of climate change, and was not restricted to territorially limited, local situations. The Court recognized that the standard of due diligence for preventing significant harm to the climate system is stringent. This meant that States are expected to display a heightened degree of vigilance and that preventive measures are required. Customary international law, the Court held, also enshrines a duty for States to cooperate with each other. In addition, the Court flagged principles of sustainable development, CBDR-RC, equity, intergenerational equity, precautionary principle as applicable guiding principles.

On human rights law, the Court held that a wide range of human rights were at risk in the context of climate change. Concerning the applicability of human rights obligations, it held that these were not displaced by the climate treaties as a lex specialis. Instead, it held that “the core human rights treaties, including the ICESCR [International Covenant on Economic, Social and Cultural Rights] and the ICCPR [International Covenant on Civil and Political Rights], and the human rights recognized under customary international law form part of the most directly relevant applicable law” (para. 145). It went on to find that international human rights law must inform States’ obligations under other sources of obligations, including the climate treaties and customary international law, and vice versa, in the interest of a harmonized interpretation (para. 404). The Court also recognized the importance of the right to a healthy environment, which it described as “inherent in the enjoyment of other human rights” (para. 393). It also indicated that human rights norms could potentially apply extraterritorially.

The Court also made various findings concerning reparations, although not aimed directly ad human rights law or individual redress. It held that the main mitigation obligations set forth in the climate change treaties apply erga omnes and applied the customary rules on reparations (ARSIWA). Notably, it also emphasized the existence of production-side obligations (“[f]ailure of a State to take appropriate action to protect the climate system from GHG emissions — including through fossil fuel production, fossil fuel consumption, the granting of fossil fuel exploration licences or the provision of fossil fuel subsidies — may constitute an internationally wrongful act which is attributable to that State” (para. 427).

Pabai Pabai & Another v. Australia (Torres Strait Islander case)

Summary:
In a case modelled on the Dutch Urgenda case, a group of indigenous Torres Strait Islanders living on islands off Australia’s coast initiated domestic class action proceedings before the Federal court of Australia to claim that the Australian government has failed to protect them from climate change, leading to the progressive destruction of their ancestral islands.

This case was brought by two Torres Straits Islanders on behalf of the residents of Torres Strait Islands who have suffered loss and damage due to Australia’s conduct from about 1985. The claim categorically frames the harms allegedly suffered by the group and the risks they face as being caused by Australia’s failure to exercise due care in protecting them from climate-related harms. Apart from sea level rise, extreme weather events, harm to marine ecosystems and increased disease risks, the plaintiffs allege that Australia’s conduct threatens the loss of their distinctive customary culture- Ailan Kastom, which entails a spiritual connection with their land and the practice of marine hunting and fishing.

Context:
In another, separate climate claim, a group of eight Torres Strait islanders took a Communication to the United Nations Human Rights Committee in 2019, alleging that Australia had violated the human rights of low-lying islanders because of its failure to take climate action. On 21 July 2022, the Human Rights Committee adopted its Views in this case, known as the Billy and Others v. Australia case.

Petitioners:
This case was brought by two First Nations leaders on behalf of the remote Torres Strait islands of Boigu and Saibai. They brought the case on their own behalf and “on behalf of all persons who at any time during the period from about 1985 and continuing, are of Torres Strait Islander descent and suffered loss and damage as a result of the conduct of the Respondent”.

Arguments made:
While their claim is essentially based on the Torres Strait Islanders native title rights under the Native Title Act 1993, the plaintiffs also drew upon a wider body of norms regarding the Torres Strait Islanders as well as the environment in and around the Torres Strait Islands, emanating from international law, domestic law and policy commitments.  

Based on scientific evidence, the plaintiffs argued that climate change is already threatening their native title rights and distinctive customary culture. They alleged that, due to the progression of climate change and the increasing storms and rising sea levels that result from this, they face an increasing threat of floods and of rising salt concentrations in their soil. Some islands, they argue, could become uninhabitable if the global temperature rises to levels more than 1.5°C above pre-industrial levels. One of the plaintiffs noted that that his people have lived on the islands in question for over 65,000 years.

The plaintiffs alleged that the Australian government owes a duty of care to Torres Strait Islanders. It must, in other words, take reasonable measures to protect them, their environment, their culture and their traditional way of life from the harms caused by climate change. Because current climate action and targets are not consistent with the best available climate science, they argue, they argued that this duty of care has been breached. They invoked the Torres Strait Treaty, which requires the Australian government to protect and preserve the marine environment in the region.

Relief sought:
The plaintiffs sought declarations that Australia owes a duty of care to the Torres Strait Islanders which requires reasonable protective measures aimed at the Islanders, their traditional way of life and the marine environment; and that Australia has breached this duty. They further requested the court to order an injunction requiring Australia to implement both climate adaptation and mitigation measures that are consistent with best available science and the payment of compensation for loss and damage.

The plaintiffs sought both mitigation and adaptation measures and relied on the duty of care recognized in the Sharma case.

Fact-finding:
In 2023, representatives of the Federal Court traveled to the Torres Strait to collect evidence from members of the community.

A hearing of expert evidence was held in this case on the premises of the Federal Court in Melbourne starting in late October 2023.  

Ruling of 15 July 2025:
On 15 July 2025, the Federal Court of Australia found that there had been no negligence in this case. In (Pabai v Commonwealth of Australia (No 2) [2025] FCA 796), the court rejected both of the prima facie negligence and their alternative duty of care claims brought by the Torres Strait Islanders, represented by Pabai Pabai and Guy Paul Kabai. The Court found that the applicants failed to prove any of the essential elements of their case: duty, breach, causation, damages. The court orders the parties to confer and within six weeks of the judgment to provide agreed draft orders giving effect to the judgment or in the case of no agreement, competing draft orders and a note as to whether an oral hearing is requested to resolve outstanding issues.

Sharma and Others v. Minister for the Environment

Summary:

In Sharma and Others v. Minister for the Environment, issued on 27 May 2021 by the Federal Court of Australia, a group of children and their litigation representative, Sister Marie Brigid Arthur, argued that the Australian Minister for the Environment owes them and other Australian children a duty of care in approving coal mining projects because of the risk of future climate change related harms, and sought an injunction against the project. Given the evidence of climate harms, the judge concluded that the Minister does have a duty of care towards children, but rejected the application for an injunction.

On 15 March 2022, the Government won its appeal against the judgment in this case. While the Full Federal Court upheld the primary judge’s factual findings, it unanimously (although based on several different strands of reasoning) overturned the ruling on the Ministry’s duty of care when exercising her statutory functions under the EPBC Act.

Date:

27 May 2021 (appeal judgment: 15 March 2022)

Merits:

The case concerned a decision by the Minister to approve the extraction of coal from a coal mine. The judge considered the available evidence about the degree of risk and the magnitude of the risk of harm alleged by the applicants, as well as the foreseeability and likelihood of that harm arising and being caused or contributed to by coal-related CO2 emissions. The judge concluded that the Minister does have a duty of care towards children.

The judgment recognizes that “the risk of harm to the Children from climatic hazards brought about by increased global average surface temperatures, is on a continuum in which both the degree of risk and the magnitude of the potential harm will increase exponentially if the Earth moves beyond a global average surface temperature of 2°C, towards 3°C and then to 4°C above the pre-industrial level.”

At issue was the question of whether the emissions from the mine would be within the remaining carbon budget to be respected in order to keep warming below 2 degrees Celsius. On this, and putting the onus of compliance with this budget on the respondent Minister, the Judge held that he did not have sufficient evidence to conclude that this would not be the case. He noted that:

“The Minister called no evidence. The Minister essentially contended that the Court should infer that the 100 Mt of CO2 would likely be emitted in accordance with the Paris Agreement. There is no sufficient basis for that inference. The Minister relied upon little else than speculation, in circumstances where the evidence showed that at least one of the potential consumers of the coal is not a signatory to the Paris Agreement.”

Remedies:

The Judge rejected the applicant’s request for an injunction, considering that the duty of care had not yet been breached, and that it was appropriate to await the outcome of the Minister’s decision-making process.

In a follow-up judgment, issued on 8 July 2021, the Judge ordered the Minister to pay the claimants’ costs, and held that the Minister has a duty to take reasonable care, in the exercise of her powers, to avoid causing personal injury or death to Australian children arising from carbon dioxide emissions.

Appeal:

The appeal by the Ministry of Environment challenged the primary judge’s finding of a duty of care as well as specific factual findings regarding global warming and the approved project’s contribution to that.

The Full Court upheld in full the factual basis of the case as established by the primary judge. With regards to the legal grounds, it concluded however that no duty of care for human safety should be imposed upon the Minister when exercising her power under the EPBC Act.

While each of the three judges emphasized different legal aspects, their reasoning essentially centered around the following arguments: Determining the point of breach of such a duty of care would prompt core policy questions unsuited to being answered by the judiciary. A common law duty of care would be inconsistent with the Minister’s statutory powers under the EPBC Act. There is no sufficient link between the Minister’s exercise of power and the potential harm inflicted on the children. Finally, the lack of control over the risk of harm, the absence of foreseeability of a causal injury, and indeterminacy were cited to argue against the imposition of the duty.  

Measures taken as a result of the judgment:

On 15 September 2021, the Minister granted approval for the proposed mine expansion.

Status of case:

Overturned on appeal (special leave application possible until 12 April 2022)

Padam Bahadur Shrestha v. Office of Prime Minister and Others

Summary:
The petitioner, Padam Bahadur Shrestha, had applied to the concerned authorities in Nepal to enact a separate law on climate change in August 2018, but did not receive a response. He thus filed a petition with the Supreme Court of Nepal alleging that the situation in Nepal is marked by absence of a special climate change legislation, inadequacies in existing environmental legislation in addressing climate change, and poor implementation of the State’s climate change policy. He argued that this suffices to establish a violation of the right to life, right to live in a healthy and clean environment, right to health care and right to food found in Articles 16, 30, 35, and 36 of the Nepali Constitution.

Date of decision:

25 December 2018

Court’s decision:

The Supreme Court of Nepal found that an amendment to the existing laws and introduction of a new consolidated law that addresses climate change was necessary and issued detailed directions on what features the new law must contain. It based this order on the reasons that such would facilitate Nepal’s compliance with its obligations under international law, including the Paris Agreement and that climate mitigation and adaptation directly concern fundamental rights including the right to life, right to have nutritious food and the right to a clean environment. It further held that although the Environmental Protection Act of 1997 addressed environmental protection along the dimension of climate change, its provisions were inadequate regarding climate change mitigation and adaptation.

Status of the case:

Decided.
